Hello everyone! I have been hosting this wiki for a long time. I have been hosting it since around 2010 (from Richard Berg). Although the content is maintained by several people, and I'm very grateful for their time, the hosting costs a lot of money. If you are happy with the site, please make a donation! I would be very grateful and we can keep this site alive:

=== {{ReverseHeading3|What is AviSynth?}} === __NOEDITSECTION__
AviSynth is a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a [[frameserver]], providing instant editing without the need for temporary files.
<p>
AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced [[NLE|non-linear editing]]. While this may at first seem laborious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.

External filters

2025-12-06T13:32:50Z

Admin: changed wilbertdijkhof.com to wilbertdijkhof.nl

Rough classification of third-party filters for AviSynth - a perpetual work in progress.

This page lists both scripts (see [[Import]]) and plugins (see [[Plugins]]).

== Introduction ==

==== Download sites ====
A large list of filters can be downloaded from the following sites but be aware that some plugins listed '''may be outdated''', only recommended as a backup.

*[https://web.archive.org/web/20130803185015/http://www.64k.it:80/andres/dettaglio.php?sez=avisynth Andres' Filter Collection]
*[https://chaosking.de/repo/avsfilters/ AviSynth Filter DB by ChaosKing] | [https://web.archive.org/web/20140412062911/http://chaosking.de/avisynth-filter-db mirror]
*[http://www.avisynth.info/?plugin=attach&pcmd=list&refer=%E3%82%A2%E3%83%BC%E3%82%AB%E3%82%A4%E3%83%96 AviSynth.info Filter Archive]
*[http://xhmikosr.1f0.de/_old/avisynth/plugins/ XhmikosR's Builds]
*[http://www.avisynth.nl/users/warpenterprises/ Warp Enterprises' AviSynth Filter Collection]

====64-bit filters====
'''[[AviSynth%2B_x64_plugins|Comprehensive list of AviSynth+ 64-bit filters]] →'''

====Outdated AviSynth plugins====
[[External plugins old|External plugins (old)]] - these older plugins are not recommended, page is there mainly for historical purposes.

==== Using filters ====
Most scripts will apply filters in the following order:

# Create an AviSynth clip from a video file using a source filter.
# Correct or remove any unwanted features in the video (e.g. dot crawl, field blending or telecine).
# Denoise the video (optional).
# Manipulate the video into the desired format (by e.g. changing the size and frame rate).

| [[ColorMatrix]]
| ColorMatrix corrects the colors of MPEG-2 streams. More correctly, many MPEG-2 streams use slightly different coefficients (called Rec.709) for storing the color information than AviSynth's color conversion routines or the XviD/DivX decoders (called Rec.601) do, with the result that DivX/XviD clips or MPEG-2 clips encoded by TMPGEnc/QuEnc are displayed with slighty off colors. This can be checked by opening the MPEG-2 stream directly in VDubMod.

|SegmentDisplayOCR is a seven-segment display recognition filter for AviSynth. It has built in logging functionality (it will log frame recognition results) and also can be used in AviSynth conditional filters. The main purpose of this filter is to process readings of various digital instruments (e.g. digital multimeters) captured on video. So if your favourite instrument lacks interface for connecting it to PC you can capture it's readings on cam and convert them to computer readable format with SegmentDisplayOCR filter.

| TMonitor is a filter very similar to AVSMon. It enables monitoring of an Avisynth clip via previewing the video, viewing clip information (such as video width, height, colorspace, number of frames, audio samples, sample rate, number of audio channels, and more), and adjusting the audio delay. It also supports multiple instances per script, allowing viewing of differences between different parts of a processing chain.

Hello everyone! I have been hosting this wiki for a long time. I have been hosting it since around 2010 (from Richard Berg). Although the content is maintained by several people, and I'm very grateful for their time, the hosting costs a lot of money. If you are happy with the site, please make a donation!

=== {{ReverseHeading3|What is AviSynth?}} === __NOEDITSECTION__
AviSynth is a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a [[frameserver]], providing instant editing without the need for temporary files.
<p>
AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced [[NLE|non-linear editing]]. While this may at first seem laborious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.
</p>

Hello everyone! I have been hosting this wiki for a long time. I have been hosting it since around 2010 (from Richard Berg). Although the content is maintained by several people, and I'm very grateful for their time, the hosting costs a lot of money. If you are happy with the site, please make a donation! I would be very grateful and we can keep this site alive:

=== {{ReverseHeading3|What is AviSynth?}} === __NOEDITSECTION__
AviSynth is a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a [[frameserver]], providing instant editing without the need for temporary files.
<p>
AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced [[NLE|non-linear editing]]. While this may at first seem laborious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.

Hello everyone! I have been hosting this wiki for a long time. I have been hosting it since around 2010 (from Richard Berg). Although the contents is maintained by several people and I'm very grateful for there time, the hosting costs a lot of money. If you are happy with the site please give a donation! I would be very grateful and we can keep this site a live. You can donate by buying me a coffee: https://buymeacoffee.com/avisynth

=== {{ReverseHeading3|What is AviSynth?}} === __NOEDITSECTION__
AviSynth is a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a [[frameserver]], providing instant editing without the need for temporary files.

AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced [[NLE|non-linear editing]]. While this may at first seem tedious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.

Please put <nowiki>~~~</nowiki> behind your comments to add your name/date.

I tried to download avisynth but get a message that I need administrator rights to install it. I have administrator rights and have never had a problem downloading anything before. Any idea what's wrong? Anyone else have this problem?

:See [http://forum.doom9.org/showthread.php?t=97406]. Apperently you are not the only one with this problem. Uninstalling it first solves the problem. What is the latest AviSynth version which installs without problems? [[User:Wilbert|Wilbert]] 03:39, 31 March 2006 (EST)

The Resize (tried Bicubic and Spline36) function crashes AviSynth on my Windows Vista 64-bit, 8GB RAM (core2quad). Everything else works fine - including all other functions/filters I tried.

I would like to port all the plugins documentation (website / readme files) and the plugins themself into this wiki so no data get lost because of canceled webhosting services, removed images, etc. Can i just start or do i have to ask the plugin developer for permission before? What if the developer does not reply at all? Is there a special wiki page naming system i should follow? Does the server behind avisynth.org have enough power to host the whole wiki & files or should i help with my own ded. server? :) Thanks! [[User:An3k|an3k]] 12:58, 21 December 2012 (UTC)

i would like to buy your website , is it for sale?

if yes reply me at yonielbb1@gmail.com with the price

I was trying to support old links such as this:<br>
http://avisynth.org/mediawiki/FAQ_frameserving <br>
...which I encountered here:<br>
http://forum.doom9.org/showpost.php?p=1360122&postcount=6

Sadly it does not work. To support old links like this would require a web-server level [http://httpd.apache.org/docs/2.2/mod/mod_alias.html redirect] in your web root [[wikipedia:.htaccess|<code>.htaccess</code>]] file - something like:
RedirectMatch permanent '/mediawiki/' http://avisynth.nl/index.php/
I believe this would fix all old links like the one above - or at least do no harm. I have done similar redirects for another site, required by a complete site reorganization while not breaking old URLs, and it worked very well.<br>
Your web host may prefer you add redirects through the admin control panel, rather than edit <code>.htaccess</code> directly. Either way is good.<br>

== Best CBD Products ==

I tried CBD products in the interest of the beginning term pattern week, and I'm genuinely surprised by the results. I've struggled with nervousness and auxiliary sleeplessness, and CBD seemed to tender a arcane, still effectual, have of coolness and relaxation. There was no 'high-pitched,' perfectly a unruffled easing of my foreboding symptoms and a more tranquillizing night's sleep. It tasted a bit dirty, but that's a miniature trade-off for feeling more at peace. I'm looking forward to seeing how it helps in the desire run.

== Try cannabis products! ==

Infuriating hemp flower quest of the first metre was an eye-opening experience. The relaxation and euphoria were unexpected but welcomed. It enhanced my sensory appreciation and sparked a newfound appreciation appropriate for music and art. Anyway, the highly-strung mania caught me off guard. Total, it was a historic introduction to a late the human race of sensations.

==== 2.60 alpha ====

''v.2.6.0 ST, 32-bit at SourceForge (still in alpha stage)''

Shouldn't a note be put up to encourage people to get this version, something like (in StainlessS's words, [http://forum.doom9.org/showthread.php?p=1690445#post1690445 here]) <blockquote>''v2.6 is much better. If you don't like the alpha status, then just don't use 2.6 additional colorspaces or functions - 2.58 compatible stuff is considerably more stable.''</blockquote> [[User:Raffriff42|Raffriff42]] 05:34, 20 August 2014 (CEST)
(EDIT forgot to add four ~'s for auto-sig)

-- -- --

Yeah I've thought about doing something like this. Maybe create a page exclusively for AviSynth 2.6 info and add all possible references in hope of convincing people to use 2.6 over 2.5.8?

*IanB: http://forum.doom9.org/showthread.php?p=1629125#post1629125 (note: this was written during the alpha4 phase, maybe some of the things mentioned no longer apply to alpha5?)
<blockquote>As a 2.5.8 replacement 2.6.0 should be just as stable. It passes all current the 2.5 regression tests, while 2.5.8 fails a few due to bugs being fixed and test to expose them being added. Most problems show up in new code, so if you use the new 2.6 features, that is where you might expect to find problems. A lot of people are downloading 2.6. And the only 2.5 bug reports I seem to get are for things broken in 2.5.8 as well, the few 2.6 bug reports are to do with things like YV24 overlay and YV411 text painting.

I have most of the API changes mapped out to cover hooks for expected features for 2.6.1 and 2.6.2 like extra colour spaces and threading so that 2.6 plugins won't need to be recompiled. I have a long standing bug in the cache from 2.5.7 that I am working on at present and I intend to do an Alpha 5 release when I finish and test that fix. If Alpha 5 stands up without any new bugs I will probably promote it to Release Candidate 1, i.e. 1st Beta release.</blockquote>

*Doom9 thread: [http://forum.doom9.org/showthread.php?t=168478 Which Avisynth version are you using?] - A poll which clearly shows that most people are using 2.6.

I also have my own little rant on this very issue: http://forum.doom9.org/showthread.php?p=1684284#post1684284 - nothing of importance just frustrated that people are still using 2.5.8 and still have the audacity to complain.

<div style="max-width:62em" >

{{AvsPlusFullname}}<br>
Up-to-date documentation: [https://avisynthplus.readthedocs.io/en/latest/avisynthdoc/corefilters/resize.html https://avisynthplus.readthedocs.io]
</div>

Scales the input video frames to an arbitrary new resolution, and optionally crops the frame before resizing with sub-pixel precision.

There are trade-offs to be considered between preservation (or augmentation) of image detail and possible artifacts (i.e., oversharpening).
</div>
__TOC__

== Common Parameters ==

{{Par2|target_width, target_height|int|}}
:Width and height of the returned clip.

{{Par2|src_left, src_top|float|0, 0}}
:See [[#Cropping |cropping]] discussion below.
<div {{ListItemContinue|2}} >
Cropping of the {{FuncArg|left}} and {{FuncArg|top}} edges respectively, in pixels, before resizing.
</div>

{{Par2|src_width, src_height|float|(source width, height)}}
:See [[#Cropping |cropping]] discussion below.
<div {{ListItemContinue|2}} >
As with [[Crop]], these arguments have different functionality, depending on their value:
* If  > zero, these set the '''width''' and '''height''' of the clip before resizing.
* If <= zero, they set the cropping of the '''right''' and '''bottom''' edges respectively, before resizing.
Note, there are certain limits:
* {{FuncArg|clip}}.[[Clip_properties|Width]] must be >= ({{FuncArg|src_left}} + '''width''')
* {{FuncArg|clip}}.[[Clip_properties|Width]] must be >  ({{FuncArg|src_left}} + '''right''')
* {{FuncArg|clip}}.[[Clip_properties|Height]] must be >= ({{FuncArg|src_top}} + '''height''')
* {{FuncArg|clip}}.[[Clip_properties|Height]] must be >  ({{FuncArg|src_top}} + '''bottom''')
...otherwise it would enlarge ("un-crop") the clip, or reduce width or height to 0, which is not allowed.
</div>

== Cropping ==
<div style="max-width:62em" >
* All resizers have an expanded syntax which '''crops''' the frame before resizing:
<div {{BoxWidthIndent|54|3}} >
BilinearResize(100, 150, ''src_left''=10, ''src_top''=10, ''src_width''=200, ''src_height''=300)
</div>
<div {{ListItemContinue}} >
...or more succinctly:
</div>
<div {{BoxWidthIndent|54|3}} >
BilinearResize(100, 150, 10, 10, 200, 300)
</div><div {{ListItemContinue}} >
The operations are the same as if you put [[Crop]] before the Resize:
</div>
<div {{BoxWidthIndent|54|3}} >
Crop(10, 10, 200, 300).BilinearResize(100, 150)
</div>

*Note the cropping parameters are all [[Script_variables|floating point]]. This allows any '''Resize''' filter to be used as a sub-pixel shifter. <sup>[http://forum.doom9.org/showpost.php?p=938102&postcount=2]</sup>

*Note that [[Crop]] gives a hard boundary, whereas the '''Resize''' filters interpolate pixels outside the cropped region – depending on the resizer kernel – bilinear, bicubic etc, and not beyond the edge of the image.

*As a general rule,
** [[Crop]] any hard borders or noise; '''Resize''' cropping may propagate the noise into the output.
** Use '''Resize''' cropping to maintain accurate edge rendering when excising a part of a complete image.

*Negative cropping is allowed; this results in repeated edge pixels as shown below:
<div {{BoxWidthIndent|54|3}} >
BilinearResize(Width, Height, -64, -64, Width, Height)
</div>
:[[File:Sintel_frm6291_Resize_shift.jpg|680px]]
</div>

== BilinearResize ==
<div style="max-width:62em" >
{{FuncDef
|BilinearResize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'' ] )
}}

'''BilinearResize''' uses standard [[Wikipedia:Bilinear_filtering|bilinear filtering]] and is a good choice for smoothing overly sharp sources.
</div>

== BicubicResize ==
<div style="max-width:62em" >
{{FuncDef
|BicubicResize(clip ''clip'', int ''target_width'', int ''target_height'' [, float ''b'', float ''c'', <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'' ] )
}}

'''BicubicResize''' is similar to [[#BilinearResize|BilinearResize]], except that instead of a linear filtering function it uses the [[Wikipedia:Mitchell–Netravali_filters|Mitchell–Netravali]] two-part cubic. The parameters {{FuncArg|b}} and {{FuncArg|c}} can be used to adjust the properties of the cubic; they are sometimes referred to as "blurring" and "ringing" respectively.

If you are enlarging your video, you will get sharper results with '''BicubicResize''' than with BilinearResize. However, if you are shrinking it, you may prefer [[#BilinearResize|BilinearResize]] as it performs some [[Wikipedia:Spatial_anti-aliasing#Examples|antialiasing]].

==== parameters ''b'' and ''c'' ====
{{Par2|b, c|float|1/3}}
:The default for both {{FuncArg|b}} and {{FuncArg|c}} is 1/3, which were recommended by Mitchell and Netravali for having the most visually pleasing results.

<div {{ListItemContinue|2}} >
Set [{{FuncArg|b}} + 2{{FuncArg|c}} = 1] for the most numerically accurate filter. This gives, for {{FuncArg|b}}=0, the maximum value of 0.5 for {{FuncArg|c}}, which is the [[Wikipedia:Cubic_Hermite_spline#Catmull.E2.80.93Rom_spline|Catmull-Rom spline]] and a good suggestion for sharpness.

Larger values of {{FuncArg|b}} and {{FuncArg|c}} can produce interesting op-art effects – for example, try ({{FuncArg|b}}=0, {{FuncArg|c}}= -5.0).

As {{FuncArg|c}} exceeds 0.6, the filter starts to [[Wikipedia:Ringing_artifacts|"ring"]] or overshoot. You won't get true sharpness – what you'll get is exaggerated edges.
Negative values for {{FuncArg|b}} (although allowed) give undesirable results, so use {{FuncArg|b}}=0 for values of {{FuncArg|c}} > 0.5.

With ({{FuncArg|b}}=0, {{FuncArg|c}}=0.75) the filter is the same as [http://www.virtualdub.org/blog/pivot/entry.php?id=95 VirtualDub's "Precise Bicubic"].

'''BicubicResize''' may be the most visually pleasing of the '''Resize''' filters for ''downsizing'' to half-size or less.<sup>[http://forum.doom9.org/showthread.php?t=172871&page=2 doom9]</sup><br>Try the default setting, ({{FuncArg|b}}=0, {{FuncArg|c}}=0.75) as above, or ({{FuncArg|b}}= -0.5, {{FuncArg|c}}=0.25).
</div>
</div>

== BlackmanResize ==
<div style="max-width:62em" >
{{FuncDef
|BlackmanResize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'', int ''taps'' ] )
}}

'''BlackmanResize''' is a modification of LanczosResize that has better control of [[Wikipedia:Ringing_artifacts|ringing]] artifacts for high numbers of {{FuncArg|taps}}.

==== parameter ''taps'' ====
{{Par2|taps|int|4}}
:See [[#lanczos_taps|LanczosResize]] for an explanation of the {{FuncArg|taps}} argument (default 4, range 1-100).
</div>

== GaussResize ==
<div style="max-width:62em" >
{{FuncDef
|GaussResize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'', float ''p'' ] )
}}

'''GaussResize''' uses a [[Wikipedia:Gaussian_filter|gaussian]] resizer, which unlike the bicubics, does not overshoot – but perhaps does not appear as sharp to the eye.

==== parameter ''p'' ====
{{Par2|p|float|30.0}}
:Sharpness. Range from about 1 to 100, with 1 being very blurry and 100 being very sharp.
</div>

== LanczosResize ==
<div style="max-width:62em" >
{{FuncDef
|LanczosResize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'', int ''taps'' ] )
}}

{{FuncDef
|Lanczos4Resize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'' ] )
}}

'''LanczosResize''' is a sharper alternative to [[#BicubicResize|BicubicResize]]. It is NOT suited for low bitrate video; the various Bicubic flavours are much better for this.

'''Lanczos4Resize''' is a short hand for <code>LanczosResize(taps=4)</code>. It produces sharper images than LanczosResize with the default {{FuncArg|taps}}=3, especially useful when upsizing a clip.

<div id="lanczos_taps" style="display:inline;font-size:50%;height:0;line-height:0;overflow:hidden;"></div>
==== parameter ''taps'' ====
{{Par2|taps|int|3}}
:Basically, {{FuncArg|taps}} affects sharpness. Default 3, range 1-100. Equal to the number of filter [[Wikipedia:Lanczos_resampling#Lanczos_kernel|''lobes'']] (ignoring mirroring around the origin).

<div {{ListItemContinue|2}} >
''Note:'' the input argument named {{FuncArg|taps}} should really be called "lobes". When discussing resizers, "taps" has a different meaning, as described below:

<div {{ListItemContinue|1}} >
{{BoldColor|black|120|“}}So when people talk about Lanczos2, they mean a 2-lobe Lanczos-windowed sinc function. There are actually 4 lobes -- 2 on each side...

For upsampling (making the image larger), the filter is sized such that the entire equation falls across 4 input samples, making it a 4-tap filter. It doesn't matter how big the output image is going to be - it's still just 4 taps. For downsampling (making the image smaller), the equation is sized so it will fall across 4 *destination* samples, which obviously are spaced at wider intervals than the source samples. So for downsampling by a factor of 2 (making the image half as big), the filter covers 8 input samples, and thus 8 taps. For 3X downsampling, you need 12 taps, and so forth.

The total number of taps you need for downsampling is the downsampling ratio times the number of lobes, times 2. And practically, one needs to round that up to the next even integer. For upsampling, it's always 4 taps.{{BoldColor|black|120|”}}

[http://www.avsforum.com/forum/26-home-theater-computers/460922-lanczos-vs-bicubic-comparison-2.html#post4760581 Don Munsil (avsforum post)] | [[lanczos lobs/taps|mirror]].
</div>
</div>
</div>

== PointResize ==
<div style="max-width:62em" >
{{FuncDef
|PointResize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'' ] )
}}

'''PointResize''' is the simplest resizer possible. It uses a Point Sampler or [[Wikipedia:Nearest-neighbor_interpolation|Nearest Neighbour]] algorithm, which usually results in a very "blocky" image. So in general this filter should only be used, if you ''intend'' to have inferior quality, or you need the clear pixel drawings. Useful for magnifying small areas for examination.
</div>

== Spline based resizers ==
<div style="max-width:62em" >
{{FuncDef
|Spline16Resize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'' ] )
}}

{{FuncDef
|Spline36Resize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'' ] )
}}

{{FuncDef
|Spline64Resize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'' ] )
}}

'''Spline16Resize''', '''Spline36Resize''' and '''Spline64Resize''' are three [[Wikipedia:Spline_interpolation|Spline based]] resizers. They are the (cubic) spline based resizers from [http://sourceforge.net/projects/panotools/ Panorama tools] that fit a spline through the sample points and then derives the filter kernel from the resulting blending polynomials. See [http://forum.doom9.org/showthread.php?t=147117 this thread] for the technical details.

The rationale for '''Spline''' is to be as sharp as possible with less ringing artifacts than [[#LanczosResize|LanczosResize]] produces. '''Spline16Resize''' uses √16 or 4 sample points, '''Spline36Resize''' uses √36 or 6 sample points, etc ... The more sample points used, the more accurate the resampling. Several resizer comparison pages are given in the [[#External Links|External Links]] section.

*'''Spline64Resize''' may be the most accurate of the '''Resize''' filters.<sup>[http://web.archive.org/web/20060827184031/http://www.path.unimelb.edu.au/~dersch/interpolator/interpolator.html Dersch]</sup>
*'''Spline16Resize''' is sharper and [[Wikipedia:Ringing_artifacts|rings]] just a bit (which may be desirable with soft sources),<br>and looks pleasing to the eye when enlarging or reducing in moderate amounts.<sup>[http://forum.doom9.org/showthread.php?p=1689519#post1689519 doom9]</sup>
*'''Spline36Resize''' is somewhere in between the other two.
</div>

== SincResize ==
<div style="max-width:62em" >
{{FuncDef
|SincResize(clip ''clip'', int ''target_width'', int ''target_height'' [, <br>
     float ''src_left'', float ''src_top'', float ''src_width'', float ''src_height'', int ''taps'' ] )
}}

'''SincResize''' uses the truncated sinc function. It is very sharp, but prone to [[Wikipedia:Ringing_artifacts|ringing]] artifacts.

==== parameter ''taps'' ====
{{Par2|taps|int|4}}
:See [[#lanczos_taps|LanczosResize]] for an explanation of the {{FuncArg|taps}} argument (default 4, range 1-20).
</div>

== Examples ==
* Cropping:
<div {{BoxWidthIndent|42|3}} >

== Notes ==
<div style="max-width:62em" >
* AviSynth has completely separate vertical and horizontal resizers. If input is the same as output on one axis, that resizer will be skipped. The resizer with the smallest downscale ratio is called first; this is done to preserve maximum quality, so the second resizer has the best possible picture to work with. [[Filter_SDK/Data_storage|Data storing]] will have an impact on what [[Modulo|mods]] should be used for sizes when resizing and cropping; see [[Crop#Crop restrictions|Crop restrictions]].

If you have trouble loading animated GIFs, see this discussion @ doom9.org:

Try AviSynth+
Try FFmpegSource
Try LSMASHSource/LWLibavVideoSource

:Both animated gifs (that are mentioned in that thread) load fine for me. Guess they must be using the old DevIL library or so. Please don't do this without testing it yourself (and file a bug report etc ...).

=== {{ReverseHeading3|What is AviSynth?}} === __NOEDITSECTION__
<p>
AviSynth is a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a [[frameserver]], providing instant editing without the need for temporary files.

AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced [[NLE|non-linear editing]]. While this may at first seem tedious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.

Filter SDK/C API/AVS VideoInfo

2023-04-01T22:04:59Z

Admin:

The AVS_VideoInfo structure holds global information about a clip (i.e. information that does not depend on the frame number). It's a member of the AVS_FilterInfo structure. Below is a description of it (for AVISYNTH_INTERFACE_VERSION=6).

== Properties and constants ==
* Colorspace constants, Colorformat constants and Image_type constants:

:These constants are the same as the ones in the C++ API with a AVS_ prefix. For example, the C++ API constant CS_BGR becomes AVS_CS_BGR.

:For some reason these constants are not part of the AVS_VideoInfo structure. Why not???

* Colorspace properties, Image_type properties and General properties:

:These are the same as in the C++ API.

* Chroma placement constants (bits 20 -> 23):

:They are missing in the C API. Todo: add them in the API.

* Remaining constants (they are not present in the C++ API):

enum {
AVS_FILTER_TYPE=1,
AVS_FILTER_INPUT_COLORSPACE=2,
AVS_FILTER_OUTPUT_TYPE=9,
AVS_FILTER_NAME=4,
AVS_FILTER_AUTHOR=5,
AVS_FILTER_VERSION=6,
AVS_FILTER_ARGS=7,
AVS_FILTER_ARGS_INFO=8,
AVS_FILTER_ARGS_DESCRIPTION=10,
AVS_FILTER_DESCRIPTION=11
};

enum { //SUBTYPES
AVS_FILTER_TYPE_AUDIO=1,
AVS_FILTER_TYPE_VIDEO=2,
AVS_FILTER_OUTPUT_TYPE_SAME=3,
AVS_FILTER_OUTPUT_TYPE_DIFFERENT=4
};

Todo: add description.

== Functions [need to add examples] ==

These functions are not members of the AVS_VideoInfo structure, but they take an AVS_VideoInfo structure as input. Unless stated otherwise the functions have the same funcionality as the corresponding ones in the C++ API.

Note the name of the functions are basically the same as the ones in the C++ API, with a 'avs_' prefix, a AVS_VideoInfo as input, lower case letters and with a underscore between separate words in the name.

For example, instead of vi.IsYUV(), you would use avs_is_yuv(&fi->vi) where fi is a pointer to AVS_FilterInfo.

<br>
== Description ==
This filter will enable you to send clips over your network. You can connect several clients to the same machine.
<br>
<br>
== Requirements ==
* [x86]: [[AviSynth+]] or [https://sourceforge.net/projects/avisynth2/ AviSynth 2.6]
* [x64]: [[AviSynth+]]
<br>
== [[Script variables|Syntax and Parameters]] ==

=== Server: ===

<code>TCPServer</code> (clip, int "port")<br />
<br />
This will spawn a server thread on the current machine running on the specified port. Port default is 22050.<br />
You will get output in the application you open your script in, but the server will only be running as long as the application (vdub for instance) is open.<br />
<br />
Example:

<pre>Colorbars(512, 256)
TCPServer()</pre>
will start a server.
<br>
<br>
=== Client: ===

<code>TCPSource</code> (string hostname, int "port", string "compression")<br />
<br />
This will connect to the machine with the given address (IP-number for instance) to a server running on the given port. Port default is also 22050 here.

Compression enable you to choose the compression used for the video:

:{|
| '''Compression Type'''
| '''Description'''
|-
| None
| Use no compression. Fastest option - video will not be compressed before being sent over the net.
|-
| LZO
| Use [http://www.oberhumer.com/opensource/lzo/ LZO] dictionary compression. Fairly fast, but only compresses well on artificial sources, like cartoons and anime with very uniform surfaces.
|-
| Huffman
| Uses a fairly slow Huffman routine by [http://bcl.sourceforge.net/ Marcus Geelnard]. Compresses natural video better than LZO.
|-
| GZip
| Uses a [http://www.gzip.org/ Gzip] Huffman only compression. Works much like Huffman setting, but seems faster.
|}

If no compression is given, GZip is currently used by default. Interlaced material compresses worse than non-interlaced due to downwards deltaencoding. If network speed is a problem you might want to use [[SeparateFields]].

Example:

<pre>TCPSource("127.0.0.1")
Info()</pre>
This will connect to the local machine, if a server is running.
<br>
<br>
== Examples ==

You can use this to run each/some filters on different PC's. For example:

<pre># Clustermember 1:
AVISource
Deinterlacer
TCPServer

# Clustermember 2:
TCPSource
Sharpener
TCPServer

# Clustermember 3:
TCPSource
# client app -> video codec -> final file</pre>

=== Usability Notes ===

Once you have added a TCPServer, you cannot add more filters to the chain, or use the output from the filter. The server runs in a separate thread, but since AviSynth isn't completely thread-safe you cannot reliably run multiple servers. This should '''not''' be used:

<pre>
AviSource("avi.avi")
TCPServer(1001)
TCPServer(1002) # This is NOT a good idea
</pre>
So the basic rule is '''never more than one TCPServer per script'''.

Using commands after TCPServer is also a bad idea:

<pre>AviSource("avi.avi")
TCPServer(1001)
AviSource("avi2.avi") # Do not do this, this will disable the server.</pre>
AviSynth detects that the output of TCPServer isn't used, so it kills the Server filter. '''TCPServer should always be the last filter.'''
<br>
<br>
== Changelog ==
Version Date Changes<br>
v0.2 2017/02/13 - TCPDeliver for AviSynth+ version 0.2
- Differences from 0.1:
* support for YUVA/PlanarRGBA colorspaces;
* HBD formats should be handled better if compression is involved;
* dropped old garbage from source code;
* no need in the old VS runtime.

== Description ==
[[DGDecNV]] is a decoder/frameserver for AVC, HEVC, MPEG2, and VC1 streams that runs on the GPU of Nvidia graphics cards that support CUDA video decoding. It works in conjunction with the indexing tool DGIndexNV. See official homepage: http://rationalqm.us/dgdecnv/dgdecnv.html

'''DGDecodeNV.dll''' includes the following AviSynth filters:
* <code>DGSource</code>: source filter that delivers decoded video in YV12/i420/YUV420P16 format. (requires AviSynth+ for high-bit-depth work)
* <code>DGDenoise</code>: fast stand-alone CUDA filter that implements [https://en.wikipedia.org/wiki/Non-local_means NLM denoising]. Supports [[YUV420P16]].
* <code>DGSharpen</code>: fast stand-alone CUDA filter that implements limited sharpening like the well-known filter [[LimitedSharpen|LimitedSharpenFaster]](). Supports [[YUV420P16]].
* <code>DGTelecide</code>: fast stand-alone CUDA filter that implements field matching and adaptive deinterlacing.
* <code>DGDecimate</code>: fast stand-alone CUDA filter that implements N-in-M frame decimation.
* <code>DGBob</code>: fast stand-alone CUDA filter that implements the YADIF deinterlacing algorithm (original concept by Michael Niedermayer).
* <code>PVBob</code>: a stand-alone version of the PureVideo deinterlacer. This is the same functionality that you get using the deinterlace parameter of DGSource().
<br>
'''DGIndexNV'''
DGIndexNV, part of the DGDecNV package, is primarily designed to create an index of an AVC/HEVC/MPG/VC1 video stream, containing the location of each frame in the input stream, and some additional information about each frame. This index, or project file, is used by the companion Avisynth filter DGDecodeNV to provide frame-accurate serving of the video via an Avisynth script. DGDecNV can also be used with Vapoursynth because Vapoursynth can load and use Avisynth source filters. DGIndexNV can open AVC/HEVC/MPG/VC1 video in elementary streams, and in program, transport, Matroska, and MP4 containers.

{{FuncDef|Version()}}

Generates a 24[[wikipedia:Frame_rate|fps]], 10-second, [[RGB24]]-format video clip with a version, build time, copyright statement, and homepage information in 24-point, Arial, light yellow ([[Colors|$ECF2BF]]) text on a 25% grey ($404040) background. Width and height are chosen to fit the message, so clip size varies by version.

:[[File:avisynth-version-2.6.png]]

If the '''Version''' message is presented by itself (as is the normal case, when simply checking the installed AviSynth version), you don't care about the exact size, frame rate etc; but if you want to [[Splice]] this clip with other video clips, the [[Clip_properties|properties]] must be compatible: you will need more control. The following script implements a variant of the '''Version''' filter with a clip argument {{FuncArg|bg}} which defines the resulting properties, and (if {{FuncArg|showbg}}=true) the audio/video content in the background.

== Introduction ==

The Avisynth API is a C++ API, but that doesn't mean that you can use every C++ compiler to compile your plugin. Unfortunately compilers have different ideas about what the C++ ABI should look like. In practice, this means that if you want things to work 100% as expected, you must compile your plugin with the same compiler that was used to compile AviSynth. That's MSVC 6.0 for official builds. Later versions of MSVC will kinda sorta work, as will ICL (up to ICL10.1), but there are caveats (for example, you must never allow any C++ exceptions to escape your plugin ever - use ThrowError() instead - and you must always make sure memory allocated by AviSynth is freed by AviSynth itself and not by your plugin). So unfortunately it matters what C++ compiler will be used to compile a plugin.

An application binary interface ([http://en.wikipedia.org/wiki/Application_binary_interface ABI]) specifies how software components should interact with each other at the binary level (in this case AviSynth and a plugin). ABIs cover details such as the sizes, layout, and alignment of data types, the calling convention of functions' arguments that are passed and returned. It standardizes details such as the [http://en.wikipedia.org/wiki/Name_mangling#Name_mangling_in_C.2B.2B C++ name mangling] and exception propagation. The problem is that there are different C++ ABIs.

Microsoft set their general C++ ABI with their first C++ compilers, and it has had some changes along the years and versions of their compiler suite. Intel and Borland, among others, support the Microsoft ABI, and thus things built with the other generally work, just like with Linux and the ABI used by GCC. Enter MinGW.

Instead of implementing the Microsoft ABI, the people at GCC and MinGW decided to just use the same C++ ABI on Windows as they use everywhere else. Thus we have two groups of compilers that use a different ABI. It will give issues if you try to load a mingw-built C++ API DLL from a MSVC-built Avisynth. The opposite will not work, either. The C interface was made exactly for this reason, as pretty much by chance the ABI for C is (more or less) set, and thus it is generally OK to mix binaries created by different C compilers.

This is why the Avisynth C API exists: if you want a portable API, you want a C API. C++ API's are more or less by definition unportable.

This section explains how to compile Avisynth plugins that are using the C++ API and that are using the C API. For the latter see the MSVC++ 2010 section.

=== Further reading ===

If you want extra reading regarding calling conventions and name mangling and such ABI-related things, you can read the following PDF that lists quite a few things of various implementations. Available [http://www.agner.org/optimize/calling_conventions.pdf here]. Basically these things in general are not fixable by a mere header, you would have to patch a compiler for the other calling convention, as well as handle exceptions so that the other side would understand it as well. And so forth, and so forth. (source: Doom9 forum posts: [http://forum.doom9.org/showthread.php?p=1653392#post1653392], [http://forum.doom9.org/showthread.php?p=1653737#post1653737].)

== Installing necessary software ==

For installing software and setting up environments have a look at [[Filter_SDK/SDK_necessaries|necessary software]] and [[Filter_SDK/Compile AviSynth|necessary software and setting up environments]].

== Compiling AviSynth plugins step by step instructions (for MS VC++ 6.0) ==

Open VC++. Select a new project: Go to the File tab -> New. Select a Win32 Dynamic-Link Library in the Projects tab:

[[Image:Compiling_plugins.png‎]]

Add the location of your project and the Project Name. The location is the project folder where the source of your project will be.

Select "An empty DLL project":

[[Image:Compiling_plugins2.png‎]]

Copy existing source files (*.cpp), headers (*.h) and avisynth.h in your project folder. If you started from scratch, you only need to copy avisynth.h in your project folder.

Go to the Project tab -> Add To Project -> Files:

[[Image:Compiling_plugins3.png‎]]

Add the existing source files (*.cpp), headers (*.h) and avisynth.h to your project. If you start from scratch, you need to a new files to your project:

Go to the Project tab -> Add To project -> New:

1) Select C++ source file, and give it a name.
2) Select C/C++ header file (if you are going to use one), and give it a name.

Go to the Build tab -> Set Active Configuration -> select the release build.

If you go to the Project tab again -> Settings. Then you should see something similar as this:

[[Image:Compiling_plugins4.png‎]]

Save your workspace: File -> Save Workspace.

Finally, code your source/header files, and compile your plugin. Go to the Build tab -> Build (...)

== Compiling AviSynth plugins step by step instructions (for MS VC++ 2005 Express Edition) ==

=== How to compile existent (old MS VC 6.0) plugin with MS VC++ 2005 ===

* Start VC++ 2005, go to folder with old plugin (e.g. [[Filter_SDK/Simple_sample | SimpleSample]]) unpacked zip file with full source codes and project files, and open plugin workspace file SimpleSample.dsw.

* Agree in dialog to convert and open this project.

* Go to menu Build -> Configuration Manager, Set active solution configuration to Release (or Debug if you want firsly debug it).

* Go to Build -> Build Solution (F7) to compile and create SimpleSample.dll

* If you get fatal error LNK1181: cannot open input file 'odbc32.lib', then go to menu Project -> SimpleSample Properties. Select Configuration Properties -> Linker -> Input -> Additional Dependencies, and remove extra unneeded libraries like odbc32.lib, odbccp32.lib.

* Also check Linker -> Output File option there and set approriate pathname (or Inherit From Process default).

* You can make some changes (edit) of source codes if you want.

* Repeat command Build -> Build Solution (F7) to compile and create SimpleSample.dll

=== How to create new plugin from scratch with MS VC++ 2005 ===

* Start VC++2005.
* Menu: fiIe -> Create new project.
* Select Win32 console appication.
* Enter name of your new project and press OK.
* You will in Win32 Appcilation Wizard. Press Application Settings (left panel).
* Select Application Type as DLL (but it may be console too).
* At Additional options select "Empty project"
* Copy files to project folder with Explorer.
* Add header file avisynth.h to the project: Menu Project -> Add existent item. Also add existant (e.g. simplesample.cpp) or create new CPP files by Project -> Add new item.
* Go to menu Build -> Configuration Manager, Set active solution configuration to Release (or Debug if you want firsly debug it).
* Make some changes (edit) of source codes to implement your algorithm. See [[Filter_SDK/Simple_sample | SimpleSample]] or some other open source plugin source code and Avisynth [[Filter SDK]] for details.
* Go to Build -> Build Solution (F7) to compile and create plugin SimpleSample.dll

== Compiling AviSynth plugins step by step instructions (for MS VC++ 2008 Professional Edition) ==

* In this guide, we will compile the Example plugin from CPP for C programmers, from http://forum.doom9.org/showthread.php?p=1538557#post1538557 or directly from http://www.mediafire.com/download.php?tc61m9otustmy29
* Start Microsoft Visual Studio 2008
* Upon first start, you are asked to set up your environment. You may choose the typical Visual C++ option
* Choose File->New->Project or click the New Project icon
* On the left pane, under Project Types, expand Visual C++ and select Win32
* On the right pane, choose Win32 Console Application
* Enter a name for your project (in this example we will use Example), click OK
* You may get an error: An error has occurred in this dialog, Error: 54, Unspecified Error. This may be because you installed some windows updates but didn't reboot yet. Click OK.
* You are shown the current project settings. Click Next.
* Under Application Type, click the DLL option. Under Additional options, check the Empty project box.
* A new directory is created, My Documents\Visual Studio 2008\Projects\Example
* You need to extract the files from our example plugin into My Documents\Visual Studio 2008\Projects\Example\Example
* In the default layout, there is a Solution Explorer pane on the left side. Right click Header Files, and select Add->Existing Item, select avisynth.h and click Add
* Continue to add the other files, Info.h and InfoF.h
* Right click Source Files, select Add->Existing Item, and select Example.cpp

To fix this, double-click that error line to highlight it's location in the example.cpp source file. Change 'const wstep = (vi.IsRGB24()) ? 3 : 4; // 3 bytes for RGB24, & 4 for RGB32.' to 'const int wstep = (vi.IsRGB24()) ? 3 : 4; // 3 bytes for RGB24, & 4 for RGB32.'
* Click Build->Build Solution
* If you get an error 'unresolved external symbol _main referenced in function ___tmainCRTStartup', then you're trying to build an .exe. Use Project->Example Properties, Configuration Properties, General, set Configuration Type to Dynamic Library (.dll)
* By default, a debug version is made. To change this, Build->Configuration Manager, select Release in the left drop-down
* You will have to re-apply the configuration changes: Project->Example Properties, Configuration Properties, General, Configuration Type=Dynamic Library (.dll) and Character Set=Use Multi-Byte Character Set
* The following file should appear: My Documents\Visual Studio 2008\Projects\Example\Release\Example.dll. Note that there is also a directory My Documents\Visual Studio 2008\Projects\Example\Example\Release which contains only tempory files, but not the dll. This is set under Project->Example Properties, General, Output Directory=$(SolutionDir)$(ConfigurationName), Intermediate Directory=$(ConfigurationName). In this case $(SolutionDir)=My Documents\Visual Studio 2008\Projects\Example, $(ConfigurationName)=Release.
* You need to copy Example.dll to your Avisynth plugins directory, and then test it with the Example.avs file.
* If everything worked, you can proceed to modify the example by following the comments, or also using the SimnpleSample included in the Avisynth distribution.

== Compiling AviSynth plugins or console applications step by step instructions (for MS VC++ 2010 Express and Professional Edition) ==

These instructions are also valid for the 2008 editions. Be sure to start with the [[Filter_SDK/SDK_necessaries|necessary software]] and [[Filter_SDK/Compile AviSynth|necessary software and setting up environments]].

=== Creating a new project ===

Open MSVC++ 2010. Select a new project:

[[Image:Compiling_plugins_msvc2010_001.jpg|720px]]

Select a Win32 Console Application. Add the location of your project and the project name. The Location\Name will be the project folder (or Solution Directory as MSVC++ 2010 calls it) where the source of your project will be. If the folder "Name" already exists the 'Create directory for solution' box should be left unchecked, otherwise it will create as a subfolder regardless.

[[Image:Compiling_plugins_msvc2010_002.jpg|720px]]

Select application settings. When creating a plugin check the application type 'DLL' and when creating a console application (such as avs2wav.exe for example) check the application type 'Console application'. Also check the additional option 'Empty project' boxes. Click on finish:

[[Image:Compiling_plugins_msvc2010_003.jpg]]

=== Adding files to the project ===

In the Solution Explorer window, the solution has the 'folders' External Dependencies, Header Files, Resource Files and Source Files:

[[Image:Compiling_plugins_msvc2010_004.jpg]]

* When creating a plugin using the C++ API, you need to copy the existing source files (*.cpp), headers (*.h) and avisynth.h in your project folder. If you started from scratch, you only need to copy avisynth.h in your project folder.

* When creating a plugin using the C API, you need to copy the existing source files (*.c), headers (*.h) and avisynth_c.h in your project folder. If you started from scratch, you only need to copy avisynth_c.h in your project folder. Note make sure your source files end with '.c' instead of '.cpp' (that's how for example MSVC++ knows it's C code).

You can add the source and header files to your project by right-clicking on a 'folder' (say Header Files as in the screenshot below), select Add and Existing Item (or New Item if you start from scratch):

[[Image:Compiling_plugins_msvc2010_005.jpg]]

When creating a plugin using the C API, you need to do two additional things:

* You need to link to avisynth.lib (create the folder InvertNeg/lib and copy the library to it). In the linker add lib\avisynth.lib under 'Additional Dependencies' (both for the release and debug configuration):
:[[Image:Compiling_cplugins_msvc2010_001.jpg]]

* When compiling with MSVC++ you also need to add a definition file to your project (otherwise LoadCPlugin can't load the library). Create a text file (here named InvertNeg.def), add it to your project (under source files) and add it to the 'Module Definition File' in the linker (both for the release and debug configuration):
:[[Image:Compiling_cplugins_msvc2010_002.jpg]]

Select the release build, since we are building the release build.

=== General settings ===

If it's your first time you use the compiler, you need to select the expert settings to make the build tab visible:

Tools > Settings > Expert Settings

[[Image:Compiling_plugins_msvc2010_006.jpg|720px]]

In the property page you can see (and change) the location of the DLL that will be build:

Right click on the project name (InvertNeg in our case) > Properties > Configuration Properties > General

The default location is $(SolutionDir)$(Configuration)\. You have set the 'SolutionDir' when defining the project (D:\AviSynth\Plugins\InvertNeg in our case). 'Configuration' will be the Release or Debug folder depending on which configuration you have selected.

[[Image:Compiling_plugins_msvc2010_07.jpg|720px]]

Next you need to be aware of the VC++ Directories and change them if necessary:

Right click on the project name (InvertNeg in our case) > Properties > Configuration Properties > VC++ Directories

Here you will find the location of the 'Include Directories' and others. $(VCInstallDir)include points to the include folder of MSVC++ 2010 and $(WindowsSdkDir)include to the include folder of the Microsoft Platform SDK. When including headers (such as windows.h) in your project they will be searched for in the include folders (unless you explicitly add its location when including them). So both of them should point to the correct folders.

Note that in general windows.h should be included in your project. It is the header file for accessing the Win32 API through C/C++ and it is located in the include folder of the Microsoft Platform SDK.

[[Image:Compiling_plugins_msvc2010_008.jpg]]

You can see the values of VCInstallDir and WindowsSdkDir when opening the VS command prompt:

Tools > Visual Studio > Command Prompt

The VS command prompt will be loaded. Type set and you will see the variables. They will be set when starting MSVC++ 2010 (by vsvars32.bat which is located in your <VisualStudioInstallDir>\Common7\Tools folder).

=== Building the plugin or console application ===

Now you are ready to build you DLL/EXE. Go to

Build > Build Solution

And you will find your compiled plugin in the Location\Name\Folder.

Admin: /* Introduction */

== Introduction ==

The Avisynth API is a C++ API, but that doesn't mean that you can use every C++ compiler to compile your plugin. Unfortunately compilers have different ideas about what the C++ ABI should look like. In practice, this means that if you want things to work 100% as expected, you must compile your plugin with the same compiler that was used to compile AviSynth. That's MSVC 6.0 for official builds. Later versions of MSVC will kinda sorta work, as will ICL (up to ICL10.1), but there are caveats (for example, you must never allow any C++ exceptions to escape your plugin ever - use ThrowError() instead - and you must always make sure memory allocated by AviSynth is freed by AviSynth itself and not by your plugin). So unfortunately it matters what C++ compiler will be used to compile a plugin.

An application binary interface ([http://en.wikipedia.org/wiki/Application_binary_interface ABI]) specifies how software components should interact with each other at the binary level (in this case AviSynth and a plugin). ABIs cover details such as the sizes, layout, and alignment of data types, the calling convention of functions' arguments that are passed and returned. It standardizes details such as the [http://en.wikipedia.org/wiki/Name_mangling#Name_mangling_in_C.2B.2B C++ name mangling] and exception propagation. The problem is that there are different C++ ABIs.

Microsoft set their general C++ ABI with their first C++ compilers, and it has had some changes along the years and versions of their compiler suite. Intel and Borland, among others, support the Microsoft ABI, and thus things built with the other generally work, just like with Linux and the ABI used by GCC. Enter MinGW.

Instead of implementing the Microsoft ABI, the people at GCC and MinGW decided to just use the same C++ ABI on Windows as they use everywhere else. Thus we have two groups of compilers that use a different ABI. It will give issues if you try to load a mingw-built C++ API DLL from a MSVC-built Avisynth. The opposite will not work, either. The C interface was made exactly for this reason, as pretty much by chance the ABI for C is (more or less) set, and thus it is generally OK to mix binaries created by different C compilers.

This is why the Avisynth C API exists: if you want a portable API, you want a C API. C++ API's are more or less by definition unportable.

This section explains how to compile Avisynth plugins that are using the C++ API and that are using the C API. For the latter see the MSVC++ 2010 section.

=== Further reading ===

If you want extra reading regarding calling conventions and name mangling and such ABI-related things, you can read the following PDF that lists quite a few things of various implementations. Available [http://www.agner.org/optimize/calling_conventions.pdf here]. Basically these things in general are not fixable by a mere header, you would have to patch a compiler for the other calling convention, as well as handle exceptions so that the other side would understand it as well. And so forth, and so forth. (source: Doom9 forum posts: [http://forum.doom9.org/showthread.php?p=1653392#post1653392], [http://forum.doom9.org/showthread.php?p=1653737#post1653737].)

== Installing necessary software ==

For installing software and setting up environments have a look at [[Filter_SDK/SDK_necessaries|necessary software]] and [[Filter_SDK/Compile AviSynth|necessary software and setting up environments]].

== Compiling AviSynth plugins step by step instructions (for MS VC++ 6.0) ==

Open VC++. Select a new project: Go to the File tab -> New. Select a Win32 Dynamic-Link Library in the Projects tab:

[[Image:Compiling_plugins.png‎]]

Add the location of your project and the Project Name. The location is the project folder where the source of your project will be.

Select "An empty DLL project":

[[Image:Compiling_plugins2.png‎]]

Copy existing source files (*.cpp), headers (*.h) and avisynth.h in your project folder. If you started from scratch, you only need to copy avisynth.h in your project folder.

Go to the Project tab -> Add To Project -> Files:

[[Image:Compiling_plugins3.png‎]]

Add the existing source files (*.cpp), headers (*.h) and avisynth.h to your project. If you start from scratch, you need to a new files to your project:

Go to the Project tab -> Add To project -> New:

1) Select C++ source file, and give it a name.
2) Select C/C++ header file (if you are going to use one), and give it a name.

Go to the Build tab -> Set Active Configuration -> select the release build.

If you go to the Project tab again -> Settings. Then you should see something similar as this:

[[Image:Compiling_plugins4.png‎]]

Save your workspace: File -> Save Workspace.

Finally, code your source/header files, and compile your plugin. Go to the Build tab -> Build (...)

== Compiling AviSynth plugins step by step instructions (for MS VC++ 2005 Express Edition) ==

=== How to compile existent (old MS VC 6.0) plugin with MS VC++ 2005 ===

* Start VC++ 2005, go to folder with old plugin (e.g. [[Filter_SDK/Simple_sample | SimpleSample]]) unpacked zip file with full source codes and project files, and open plugin workspace file SimpleSample.dsw.

* Agree in dialog to convert and open this project.

* Go to menu Build -> Configuration Manager, Set active solution configuration to Release (or Debug if you want firsly debug it).

* Go to Build -> Build Solution (F7) to compile and create SimpleSample.dll

* If you get fatal error LNK1181: cannot open input file 'odbc32.lib', then go to menu Project -> SimpleSample Properties. Select Configuration Properties -> Linker -> Input -> Additional Dependencies, and remove extra unneeded libraries like odbc32.lib, odbccp32.lib.

* Also check Linker -> Output File option there and set approriate pathname (or Inherit From Process default).

* You can make some changes (edit) of source codes if you want.

* Repeat command Build -> Build Solution (F7) to compile and create SimpleSample.dll

=== How to create new plugin from scratch with MS VC++ 2005 ===

* Start VC++2005.
* Menu: fiIe -> Create new project.
* Select Win32 console appication.
* Enter name of your new project and press OK.
* You will in Win32 Appcilation Wizard. Press Application Settings (left panel).
* Select Application Type as DLL (but it may be console too).
* At Additional options select "Empty project"
* Copy files to project folder with Explorer.
* Add header file avisynth.h to the project: Menu Project -> Add existent item. Also add existant (e.g. simplesample.cpp) or create new CPP files by Project -> Add new item.
* Go to menu Build -> Configuration Manager, Set active solution configuration to Release (or Debug if you want firsly debug it).
* Make some changes (edit) of source codes to implement your algorithm. See [[Filter_SDK/Simple_sample | SimpleSample]] or some other open source plugin source code and Avisynth [[Filter SDK]] for details.
* Go to Build -> Build Solution (F7) to compile and create plugin SimpleSample.dll

== Compiling AviSynth plugins step by step instructions (for MS VC++ 2008 Professional Edition) ==

* In this guide, we will compile the Example plugin from CPP for C programmers, from http://forum.doom9.org/showthread.php?p=1538557#post1538557 or directly from http://www.mediafire.com/download.php?tc61m9otustmy29

Clip properties

2017-10-29T22:44:20Z

Admin: typo

<div style="max-width:62em" >
You can access a variety of clip properties in AviSynth scripts. For example, if the variable ''clip'' holds a video clip, then ''clip''.{{FuncArg|Height}} is its height in pixels, ''clip''.{{FuncArg|FrameCount}} is its length in frames, and so on.

Clip properties can be accessed like [[Script_variables|script variables]], except that they are read-only (in [[wikipedia:C_(programming_language)|'''C''']] terminology, they cannot be ''L-values'').

__TOC__

The full list of properties:

==== Content Properties ====
* ''bool'' clip.{{Term|HasAudio}}
: Returns true if the clip has audio, false otherwise.
* ''bool'' clip.{{Term|HasVideo}}
: Returns true if the clip has video, false otherwise.

==== Video: Resolution ====
* ''int'' clip.{{Term|Width}}
: Returns the width of the clip in pixels.
* ''int'' clip.{{Term|Height}}
: Returns the height of the clip in pixels.

<div style="max-width:62em" >
In addition to [[Internal_filters|internal filters]] AviSynth has a fairly large number of other (non-clip) internal functions.

The input or/and output of these functions are not clips, but some other variables which can be used in a script.
</div>

__TOC__

== Boolean functions ==
<div style="max-width:62em" >
: These return true or false, if the condition that they test holds or not, respectively.

{{ScriptFunctionH5|IsBool||IsBool(var)}}
: Tests if {{FuncArg|var}} is of the bool type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
b = false
IsBool(b) = true
IsBool(1 < 2 && 0 == 1) = true
IsBool(123) = false
</div>

{{ScriptFunctionH5|IsClip||IsClip(var)}}
: Tests if {{FuncArg|var}} is of the clip type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >

c = [[AviSource]](...)
IsClip(c) = true
IsClip("c") = false
</div>

{{ScriptFunctionH5|IsFloat||IsFloat(var)}}
: Tests if {{FuncArg|var}} is of the float type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
f = [[Internal_functions/Numeric_functions|Sqrt]](2)
IsFloat(f) = true
IsFloat(2) = true # ints are considered to be floats by this function
IsFloat(true) = false
</div>

{{ScriptFunctionH5|IsInt||IsInt(var)}}
: Tests if {{FuncArg|var}} is of the int type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
IsInt(2) = true
IsInt(2.1) = false
IsInt(true) = false
</div>

{{ScriptFunctionH5|IsString||IsString(var)}}
: Tests if {{FuncArg|var}} is of the string type. {{FuncArg|var}} can be any expression allowed by the [[AviSynth Syntax]].
''Examples:''
<div {{BoxWidthIndent|56|2}} >
IsString("test") = true
IsString(2.3) = false
IsString([[Internal_functions/Conversion_functions|String]](2.3)) = true
</div>

{{ScriptFunctionH5|Exist||Exist(filename)}}
: Tests if the file specified by {{FuncArg|filename}} exists.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
filename = ...
clp = Exist(filename)
\ ? [[AviSource]](filename)
\ : [[Internal_functions/Control_functions|Assert]](false, "file: " + filename + " does not exist")
</div>

{{ScriptFunctionH5|Defined||Defined(var)}}
: Tests if {{FuncArg|var}} is defined. Can be used inside [[Script_functions]] to test if an optional argument has been given an explicit value.
: More formally, the function returns false if its argument (normally a function argument or variable) has the void ('undefined') type, otherwise it returns true.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
b_arg_supplied = Defined(arg)
myvar = b_arg_supplied ? ... : ...
</div>
</div>

== Control functions ==
<div style="max-width:62em" >
: These facilitate flow of control (loading of scripts, arguments checks, global settings adjustment, etc.).

{{ScriptFunctionH5|Apply||Apply(string ''func_string'' [, arg1 [, arg2 [, ... [, argn]]]] )}}
: Calls the function or filter {{FuncArg|func_string}} with arguments {{FuncArg|arg1}}, {{FuncArg|arg2}}, ..., {{FuncArg|argn}} (as many as supplied). Thus, it provides a way to call a function or filter '''by name''' providing arguments in the usual way as in a typical function call.
: Consequently, <tt>Apply("f", x)</tt> is equivalent to <tt>f(x)</tt> which in turn is equivalent to <tt>Eval("f(" + String(x) + ")")</tt>.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# here the same call to [[Resize|BicubicResize]] as in the Eval() example is shown
Apply("BicubicResize", last, 352, 288)
# Note that the clip argument must be supplied - 'last' is not implicitly assumed
</div>

{{ScriptFunctionH5|Eval||Eval(expression [, string ''name''])}}
: Evaluates an arbitrary {{FuncArg|expression}} as if it was placed inside the script at the point of the call and returns the result of evaluation (either to the [[Script_variables|variable]] that is explicitly assigned to or to the Last special variable.
: You can use '''Eval''' to construct and evaluate expressions dynamically inside your scripts, based on variable input data. Below some specific examples are shown but you get the general idea.
: Argument {{FuncArg|name}} will be shown in the error message besides the script name. Both will be followed with the line number in the script where the is error caused.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# calls [[BicubicResize]](last, 352, 288)
settings = "352, 288"
Eval( "BicubicResize(" + settings + ")" )

# results in Defined(u) == false
u = Eval("#")

# increments a global based on a variable's value
Eval("global my_counter = my_counter + " + String(increment))

# multi-line example with comment and line continuation
Eval("""
[[ColorBars]]
[[BicubicResize]](352, 288)
#FlipVertical
Subtitle(
\ "Width = " + [[Internal_functions#String|String]]([[Clip_properties|Width]]) + "\n"
\ + "Height = " + String(Height)
\ , align=7, lsp=0)
""")
</div>

{{ScriptFunctionH5|Import||Import(filename)}}
: Evaluates the contents of another script and returns that script's return value. Typically it is used to make available to the calling script library functions and the return value is not used. However this is simply a convention; it is not enforced by the [[AviSynth Syntax]]. See also the dedicated [[Import]] page in [[Internal filters]] for other possible uses.
: Possible scenarios (an indicative list) where the return value could be of use is for the library script to:
:* indicate whether it succesfully initialised itself (a bool return value),
:* inform for the number of presets found on disk (an int return value);
: the value then could be tested by the calling script to decide what action to take next.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
# here we do not care about the value (''mylib.avsi'' contains only functions)
Import("mylib.avsi")
...
# ''mysources.avsi'' loads predetermined file names from a folder into globals
okflag = [[Import]]("mysources.avsi")
source = okflag ? global1 + global2 + global3 : [[BlankClip]]()
</div>

{{ScriptFunctionH5|Select||Select(index, item0 [, item1 [, ...[, itemn]]])}}
: Returns the item selected by the {{FuncArg|index}} argument, which must be of int type (0 returns {{FuncArg|item0}}, 1 returns {{FuncArg|item1}}, ..., etc). Items can be any script [[Script_variables|variable]] or expression of any type and can even be mixed.

:If {{FuncArg|index}} is out of range, an error is raised.

''Examples:''
<div {{BoxWidthIndent|56|2}} >
# select a clip-brush from a set of presets
idx = 2
brush = Select(idx, [[AviSource]]("round.avi"),
\ rectangle, diagonal, diagonal.[[FlipHorizontal]])
</div>

Note - all branches are evaluated:
<div {{BoxWidthIndent|56|2}} >
index=1
Select(index, "zero", "one", "two",
\ Assert(false, "Select evaluates all branches"))
## NOTE this code does not run - it throws [[#Assert|Assert]] error
## because Select evaluates all branches
</div>

If this is not desired, use the [[Ternary_operator|conditional execution]] operator:
<div {{BoxWidthIndent|56|2}} >
index=1
x = (index==0) ? "zero"
\ : (index==1) ? "one"
\ : (index==2) ? "two"
\ : Assert(false, "index out of range")
</div>

{{ScriptFunctionH5|Default||Default(x, d)}}
: Returns {{FuncArg|x}} if '''Defined'''(x) is true, {{FuncArg|d}} otherwise. {{FuncArg|x}} must either be a function's argument or an already declared script variable (ie a variable which has been assigned a value) else an error will occur.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
...
}
</div>

{{ScriptFunctionH5|Assert||Assert(condition [, err_msg])}}
: Does nothing if {{FuncArg|condition}} is true; throws an error, immediately terminating script execution, if {{FuncArg|condition}} is false. In the later case {{FuncArg|err_msg}}, if supplied, is presented to the user through a dialog box; else the standard message "Assert: assertion failed" shows up.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
function myfunc(clip c, ..., int "strength") {
...
strength = Default(strength, 4) # if not supplied make it 4
Assert(strength > 0, "'strength' must be positive")
...
}
</div>

{{ScriptFunctionH5|NOP||NOP()}}
: This is a no-operation function provided mainly for conditional execution with non-return value items such as [[Import]], when no "else" condition is desired. That is, use it whenever the [[AviSynth Syntax]] requires an operation (such as with the ?: [[Operators#For_Booleans|operator]]) but your script does not need one.
: Return value: 0 (int type).
''Examples:''
<div {{BoxWidthIndent|56|2}} >
preset = want_presets ? [[AviSource]]("c:\presets\any.avi") : NOP
...
loadlib ? [[Import]]("my_useful_functions.avs") : NOP
</div>

{{ScriptFunctionH5|Undefined|v2.60|Undefined()}}
: Returns the undefined state.
: It's the state for which '''Defined'''() returns false.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
x = Undefined()
Defined(x) # == false
</div>
</div>

== Global Options ==
<div style="max-width:62em" >
{{ScriptFunctionH5|SetMemoryMax||SetMemoryMax(amount)}}
: Sets the maximum memory that AviSynth uses (in MB) to the value of {{FuncArg|amount}}. Setting to zero just returns the current Memory Max value. In the 2.5 series the default Memory Max value is 25% of the free physical memory, with a minimum of 16MB.
: The default Memory Max is also limited to 512MB.
:{|class="wikitable"

| 192
| 448
| 512
| 512
|}
: In some versions there is a default setting of 5MB, which is quite low. If you encounter problems (e.g. low speed) try to set this values to at least 32MB. Too high values can result in crashes because of 2GB address space limit.
: Return value: Actual MemoryMax value set.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetMemoryMax(128)
</div>

{{ScriptFunctionH5|SetWorkingDir||SetWorkingDir(path)}}
: Sets the default directory for AviSynth to the {{FuncArg|path}} argument.
: This is primarily for easy loading of source clips, [[Import|importing]] scripts, etc. It does not affect plugins' autoloading.
: Return value is 0 if successful, -1 otherwise.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
SetWorkingDir("c:\my_presets")
[[AviSource]]("border_mask.avi") # this loads c:\my_presets\border_mask.avi
</div>

{{ScriptFunctionH5|SetPlanarLegacyAlignment||SetPlanarLegacyAlignment(mode)}}
: Set alignment mode for [[planar]] frames. {{FuncArg|mode}} can either be true or false.
: Some older [[External_plugins|plugins]] illegally assume the layout of video frames in memory. This special filter forces the memory layout of planar frames to be compatible with prior versions of AviSynth. The filter works on the [[The_script_execution_model/Evaluation_of_runtime_scripts|GetFrame]]() call stack, so it effects filters '''before''' it in the script.
''Examples:''
<div {{BoxWidthIndent|56|2}} >
Example : Using an older version of Mpeg2Source() (1.10 or older):

LoadPlugin("...\Mpeg2Decode.dll")
Mpeg2Source("test.d2v") # A plugin that illegally assumes the layout of memory
SetPlanarLegacyAlignment(true) # Set legacy memory alignment for prior statements
[[Convert|ConvertToYUY2]]() # Statements through to the end of the script have
... # advanced memory alignment.
</div>

{{ScriptFunctionH5|OPT_AllowFloatAudio||global OPT_AllowFloatAudio = true ## default false}}
: [[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true (this option enables WAVE_FORMAT_IEEE_FLOAT audio output<sup>[http://forum.doom9.org/showthread.php?t=109608]</sup>). In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

:The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.<br>

{{ScriptFunctionH5|OPT_UseWaveExtensible||global OPT_UseWaveExtensible = true ## default false}}
: This option enables WAVE_FORMAT_EXTENSIBLE audio output. The default is WAVE_FORMAT_EX.
: '''Note:''' The default DirectShow component for .AVS files, "AVI/WAV File Source", does not correctly implement WAVE_FORMAT_EXTENSIBLE processing, so many application may not be able to detect the audio track. There are third party DirectShow readers that do work correctly. Intermediate work files written using the AVIFile interface for later DirectShow processing will work correctly if they use the DirectShow "File Source (async)" component or equivalent.

{{ScriptFunctionH5|OPT_dwChannelMask|v2.60|global OPT_dwChannelMask(int v)}}
: This option enables you to set ChannelMask. It overrides WAVEFORMATEXTENSIBLE.dwChannelMask<sup>[[http://wiki.multimedia.cx/index.php?title=WAVEFORMATEXTENSIBLE]</sup> which is set according to this table

</div>

{{ScriptFunctionH5|OPT_AVIPadScanlines|v2.60|global OPT_AVIPadScanlines = true ## default false}}
: This option enables DWORD aligned planar padding. Default is packed aligned planar padding. See [[AVIFile output emulation|memory alignment used in the AVIFile output emulation]].<br>

{{ScriptFunctionH5|OPT_VDubPlanarHack|v2.60|global OPT_VDubPlanarHack = true ## default false}}
: This option enables flipped YV24 and YV16 chroma planes. This is an hack for early versions of Virtualdub with YV24/YV16 support. <br>

{{ScriptFunctionH5|OPT_Enable_V210|{{AvsPluscon}}|global OPT_Enable_V210 = true ## default false}}
: For 10bit YUV422, [[Frameserver|Frameserve]] interleaved V210 instead of planar P210. (VfW)
<div {{BoxWidthIndent|56|2}} >
{{BoldColor|black|100|§}} ''VfW'' here means [[wikipedia:Video_for_Windows|Video For Windows]] clients such as VirtualDub are affected, but not other clients such as ffmpeg.

{{ScriptFunctionH5|OPT_Enable_Y3_10_10|{{AvsPluscon}}|global OPT_Enable_Y3_10_10 = true ## default false}}
: For 10bit YUV422, set the [[FourCC]] to Y3[10][10] ('Y', '3', 10, 10) instead of P210 ('P', '2', '1', '0'). (VfW) <br>

{{ScriptFunctionH5|OPT_Enable_Y3_10_16|{{AvsPluscon}}|global OPT_Enable_Y3_10_16 = true ## default false}}
: For 16bit YUV422, use Y3[10][16] instead of P216 (VfW)

== Conversion functions ==
<div style="max-width:62em" >
: These convert between different types.

{{ScriptFunctionH5|Value||Value(string)}}
: Converts a decimal string to its associated numeric value.
''Examples:''
<div {{BoxWidthIndent|56|2}} >

Hex (10824234) = "A52A2A"
</div>

{{ScriptFunctionH5|String||String(var [, string format_string])}}
: Converts a variable to a string. String arguments are passed along unchanged; booleans are converted to "true" or "false"; numbers (ints or floats) are formatted as described below; all other value types are converted to the empty string.
: If the variable is float or integer, it first converts it to a float and then uses {{FuncArg|format_string}} to convert the float to a string.
:The syntax of format_string is as follows:
: <code>'''%'''[flags][width][.precision]'''f'''</code>
:; ''flags'':
:: <tt>- </tt> left align (instead right align)
:: <tt>+ </tt> always print the +/- sign
:: <tt>0 </tt> padding with leading zeros
:: <tt>' '</tt> print a blank instead of a "+"

Internal filters

2017-07-10T14:24:12Z

Admin: /* Audio processing filters */

<div style="max-width:76em; min-width:48em">
The available (internal) filters are listed here and divided into categories. A short description is added, including the supported [[Color_spaces|color formats]] (and sample types for the audio filters). There are some functions which combine two or more clips in different ways. How the video content is calculated is described for each function, but [[filters_with_multiple_input_clips|here is a summary which explains which properties that the resulting clip will have]].

An alphabetical listing of the internal filters can be found [[:Category:Internal_filters|here]].

=== Interlace filters ===

These filters can be used for creating and processing field-based material (which is frame-based material separated into fields). AviSynth is capable of dealing with both progressive and interlaced material. The main problem is, that it often doesn't know what it receives from source filters. This is the reason that the field-based flag exists and can be used when dealing with interlaced material. More information about field-based video can be found [[Interlaced_fieldbased|here]].

=== Audio processing filters ===

These filters process audio. Audio samples will be automatically converted if any filters requires a special type of sample. This means that if a filter doesn't support the type of sample it is given, it will automatically convert the samples to something it supports. The internal formats supported in each filter is listed in the sample type column. A specific sample type can be forced by using the [[ConvertAudio]] functions.

{{AvsPluscon}} automatic conversion is ''not'' performed. The new behavior is to raise an error when a sample type is not compatible. It is your responsibility to use [[ConvertAudio]] where needed.

[[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true. In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.

=== Conditional and other meta filters ===

''Meta'' filters can be used to control other filters' execution. The basic characteristic of conditional filters is that their scripts are evaluated (executed) at every frame instead of when the clip is loaded. This allows for complex video processing that would be difficult or impossible to be performed by a normal AviSynth script.

Admin: /* Audio processing filters */

<div style="max-width:76em; min-width:48em">
The available (internal) filters are listed here and divided into categories. A short description is added, including the supported [[Color_spaces|color formats]] (and sample types for the audio filters). There are some functions which combine two or more clips in different ways. How the video content is calculated is described for each function, but [[filters_with_multiple_input_clips|here is a summary which explains which properties that the resulting clip will have]].

An alphabetical listing of the internal filters can be found [[:Category:Internal_filters|here]].

=== Conditional and other meta filters ===

''Meta'' filters can be used to control other filters' execution. The basic characteristic of conditional filters is that their scripts are evaluated (executed) at every frame instead of when the clip is loaded. This allows for complex video processing that would be difficult or impossible to be performed by a normal AviSynth script.

Filter SDK/CInvertNeg

2017-01-13T22:43:53Z

Admin:

I'll start off with a complete, working Avisynth C plugin. It's called "InvertNeg", and it produces a photo-negative of the input clip.

Here's InvertNeg.c:

#include "avisynth_c.h"

AVS_VideoFrame* AVSC_CC InvertNeg_get_frame(AVS_FilterInfo* fi, int n)
{
AVS_VideoFrame* src;
AVS_VideoFrame* dst;
int row_size, height, src_pitch, dst_pitch;
const BYTE* srcp;
BYTE* dstp;
int x, y, p;

int planes[] = {AVS_PLANAR_Y, AVS_PLANAR_V, AVS_PLANAR_U};

src = avs_get_frame(fi->child, n);
dst = avs_new_video_frame(fi->env, &fi->vi);

for (p=0; p<3; p++) {
srcp = avs_get_read_ptr_p(src, planes[p]);
dstp = avs_get_write_ptr_p(dst, planes[p]);
src_pitch = avs_get_pitch_p(src, planes[p]);
dst_pitch = avs_get_pitch_p(dst, planes[p]);
row_size = avs_get_row_size_p(dst, planes[p]);
height = avs_get_height_p(dst, planes[p]);

for (y = 0; y < height; y++) {
for (x = 0; x < row_size; x++) {
dstp[x] = srcp[x] ^ 255;
}
srcp += src_pitch;
dstp += dst_pitch;
}
}

avs_release_video_frame(src);
return dst;
}

AVS_Value AVSC_CC Create_InvertNeg(AVS_ScriptEnvironment* env, AVS_Value args, void* user_data)
{
AVS_Value v;
AVS_FilterInfo* fi;
AVS_Clip* new_clip = avs_new_c_filter(env, &fi, avs_array_elt(args, 0), 1);

if (!avs_is_planar(&fi->vi) || !avs_is_yuv(&fi->vi)) {
return avs_new_value_error("InvertNeg: planar YUV data only!");
}

fi->get_frame = InvertNeg_get_frame;

v = avs_new_value_clip(new_clip);

avs_release_clip(new_clip);
return v;
}

const char* AVSC_CC avisynth_c_plugin_init(AVS_ScriptEnvironment * env)
{
avs_add_function(env, "InvertNeg", "c", Create_InvertNeg, 0);
return "InvertNeg sample c-plugin";
}

Link to avisynth.lib and when using the MSVC++ compiler add the definition file. Compile this file into a DLL named InvertNeg.dll. See [[Filter_SDK/Compiling_instructions|compiling instructions]]. Now create an Avisynth script which looks something like this:

LoadCPlugin("d:\path\InvertNeg.dll")
clip = BlankClip().ConvertToYV12()
return clip.InvertNeg()

=== Line by line breakdown ===

Here's a line-by-line breakdown of InvertNeg.c:

#include "avisynth_c.h"

This header declares all the classes and miscellaneous constants that you might need when writing a plugin. All external plugins should #include it.

External plugins do not link with avisynth.dll, so they can't directly access functions that are defined in the main Avisynth source code. Therefore, every important function in avisynth_c.h is either defined inline or (???).

AVS_VideoFrame* AVSC_CC InvertNeg_get_frame(AVS_FilterInfo* fi, int n)

This function is the main callback functions for our filter. When called it should return frame n. It returns this frame as a pointer to AVS_VideoFrame.

AVSC_CC stands for Avisynth calling convention. Right now it is stdcall (it used to be cdecl when the C interface was exposes through seperate plugin). By using AVSC_CC you should be able to maintain source code compatibility when the calling convention changes.

AVS_VideoFrame* src;
AVS_VideoFrame* dst;
int row_size, height, src_pitch, dst_pitch;
const BYTE* srcp;
BYTE* dstp;
int x, y, p;

Declaring all of the variables we will need '''must be done up front''' (for the C++ plugin this is not necessary). Doing it in between the code will get you strange compile errors.

int planes[] = {AVS_PLANAR_Y, AVS_PLANAR_V, AVS_PLANAR_U};

The plugin requires planar YUV data, so we need to process the planes. Note the constants (such as AVS_PLANAR_Y) are the same as the ones in the C++ inteface, except for the 'AVS_' in front of it.

src = avs_get_frame(fi->child, n);

"child" is a member of AVS_FilterInfo, of type AVS_Clip. It generally contains the clip that was passed into the filter. For our filter to produce frame n we need the corresponding frame of the input clip. If you need a different frame from the input, all you have to do is pass a different frame number get_frame.

Note the functions (such as avs_get_frame) are similar as the ones in the C++ inteface, except for the 'avs_' in front of it.

get_frame calls are usually intercepted by Avisynth's internal caching code, so the frame request may never actually reach the child filter (meaning ???).

dst = avs_new_video_frame(fi->env, &fi->vi);

The avs_new_video_frame function allocates space for a video frame of the supplied size. (In this case it will hold our filter's output.) The frame buffer is uninitialized raw memory.

"env" is a member of AVS_FilterInfo which is a pointer to AVS_ScriptEnvironment. One instance of AVS_ScriptEnvironment is created for each AVS script.

"vi" is another member of AVS_FilterInfo. It is a structure of type AVS_VideoInfo, which contains information about the clip (like frame size, frame rate, pixel format, audio sample rate, etc.). avs_new_video_frame uses the information in this structure to return a frame buffer of the appropriate size.

Frame buffers are reused once all references to them go away. So usually memory won't need to be allocated from the heap.

for (p=0; p<3; p++) {

Loop over all planes.

srcp = avs_get_read_ptr_p(src, planes[p]);
dstp = avs_get_write_ptr_p(dst, planes[p]);

All frame buffers are readable, but not all are writable.

The rule about writability is this: A buffer is writable if and only if its reference count is one. In other words, you can only write to a buffer if no one else might be reading it. This rule guarantees that as long as you hold on to a video frame and don't write to it yourself, that frame will remain unchanged. Any buffer you get from avs_new_video_frame is guaranteed to be writable. However, frames you get from other clips via get_frame may not be writable, in which case avs_get_write_ptr will return a null pointer.

There is an is_writable method which you can call to find out if a buffer is writable or not, and there's a avs_make_writable method (described below) to ensure that it is.

src_pitch = avs_get_pitch_p(src, planes[p]);
dst_pitch = avs_get_pitch_p(dst, planes[p]);

The "pitch" of a frame buffer is the offset (in bytes) from the beginning of one scan line to the beginning of the next. The source and destination buffers won't necessarily have the same pitch.

Buffers created by avs_new_video_frame are always double word (16-byte) aligned and always have a pitch that is a multiple of 16.

row_size = avs_get_row_size_p(dst, planes[p]);

The row size is the length of each row in bytes (not pixels). It's usually equal to the pitch or slightly less, but it may be significantly less if the frame in question has been through Crop.

Since our source and destination frames have the same width and pixel format, they will always have the same row size. Thus I only need one row_size variable, and I could just as well have used dest instead of src.

height = avs_get_height_p(dst, planes[p]);

The height is the height in pixels. Again, for our filter this is the same for the source and the destination.

for (y = 0; y < height; y++) {
for (x = 0; x < row_size; x++) {
dstp[x] = srcp[x] ^ 255;
}
srcp += src_pitch;
dstp += dst_pitch;
}
}

This is the code that does the actual work. The "srcp += src_pitch; dstp += dest_pitch;" idiom is a useful way of dealing with potentially differing pitches without too much grief.

avs_release_video_frame(src);

Once we are done with a video frame it needs to be released. Releasing a video frame does not actually delete it but decrements the reference count.

return dst;

GetFrame returns the newly-created frame.

AVS_Value AVSC_CC Create_InvertNeg(AVS_ScriptEnvironment* env, AVS_Value args, void* user_data)

In order to use our new filter, we need a scripting-language function which creates an instance of it. This is that function.

Script functions written in C take three arguments. env contains the same ScriptEnvironment pointer that will later be passed to GetFrame. args contais all the arguments passed to the function by the script. user_data contains the void pointer which you passed to AddFunction (see below). Usually you won't need this.

AVS_Value is a variant type which can hold any one of the following: a boolean value (true/false); an integer; a floating-point number; a string; a video clip; an array of AVS_Values; or nothing ("undefined"). You can test which one it is with the methods avs_is_bool, avs_is_int, avs_is_float, avs_is_string, avs_is_clip, avs_is_array, and avs_defined (which returns true if the AVS_Value is not "undefined"). You can get the value with avs_as_bool, avs_as_int, etc. for arrays, you can use the avs_array_size method to get the number of elements, and avs_array_elt get the elements themselves. For convenience, avs_is_float and avs_as_float will work with integers also. But boolean values are not treated as numeric (unlike C).

The name "Create_InvertNeg" is arbitrary. This function will actually be known as "InvertNeg" in scripts, because that's the name we pass to avs_add_function below.

AVS_Value v;

v will serve as the return value.

AVS_FilterInfo* fi;
AVS_Clip* new_clip = avs_new_c_filter(env, &fi, avs_array_elt(args, 0), 1);

"avs_new_c_filter" creates a new filter. AVS_Clip is an abstract type representing a filter. In this case it will represent our new filter. "env" is the current script environment. "fi" will be set to point to our filter AVS_FilterInfo which is the concrete representation of a C filter. We will modify this structure later. "avs_array_elt(args, 0)" is accessing the first value of args, which is generally the parent clip. The last parameter, is a boolean value "store_child". It should generally always be set to true.

if (!avs_is_planar(&fi->vi) || !avs_is_yuv(&fi->vi)) {
return avs_new_value_error("InvertNeg: planar YUV data only!");
}

Our filter will not work unless the video is stored as YUV planar. If this is not the case than an error is returned.

fi->get_frame = InvertNeg_get_frame;

Here we are setting the get_frame callback. There are other callbacks (like get_audio, set_cache_hints and get_parity), but since "store_child" was set to true we do not have to worry about implementing all of them. Just the ones we need.

v = avs_new_value_clip(new_clip);

The return value is then set to the new clip returned by avs_new_c_filter. avs_new_value_clip stores the clip in an AVS_Value which will be returned by our Create_InvertNeg. It also creates a new reference to the clip.

avs_release_clip(new_clip);

We must now release the clip returned by avs_new_c_filter. In the case of an error the clip is no longer needed. Otherwise a new reference is created to the clip with avs_new_value_clip so we must release the original reference.

return v;

Finally we return our new clip. We could also have returned an error instead (instead of returning an error right away).

const char* AVSC_CC avisynth_c_plugin_init(AVS_ScriptEnvironment * env)

This is the only function which gets exported from the DLL. It is called by the script function LoadCPlugin the first time this plugin in loaded in a particular script. If several scripts are open at once and more than one of them loads this plugin, avisynth_c_plugin_init may be called more than once with different ScriptEnvironments. Therefore:

* You should not save the env parameter in a global variable.
* If you need to initialize any static data, you should do it in DLLMain, not in this function.

The main purpose of the avisynth_c_plugin_init function is to call avs_add_function.

avs_add_function(env, "InvertNeg", "c", Create_InvertNeg, 0);

As promised, we now call add_function to let Avisynth know of the existence of our filter. This function takes four arguments: the name of the new script function; the parameter-type string; the C function implementing the script function; and the user_data cookie.

The parameter type string specifies the paramaters for the function. The return value is untyped. It consists of a series of letters specinging the parameter types with 'c' for clip, 'i' for integer, 's' for string, 'b' for boolean, and 'f' for float. In addition:

* Any type can be followed with a '*' or '+' to indicate "zero or more" or "one or more" respectively. In this case all the matching arguments will be gathered into a sub-array. For example, if your type string is "is+f", then the integer argument will be args[0], the string arguments will be args[1][0], args[1][1], etc. (and there will be avs_array_size(args[1]) of them), and the float argument will be args[2].
* '.' matches a single argument of any type. To match multiple arguments of any type, use ".*" or ".+".
* Named arguments can be specified in [brackets] before the type. Named arguments are also optional arguments; if the user omits them, they will be of the undefined type instead of the type you specify.

return "InvertNeg sample c-plugin";

The return value of avisynth_c_plugin_init is a string which can contain any message you like, such as a notice identifying the version and author of the plugin. This string becomes the return value of LoadCPlugin, and will almost always be ignored. You can also just return 0 if you prefer.

== As an in-place filter ==

The InvertNeg filter could easily do its work in a single buffer, rather than copying from one buffer to another. Here's a new implementation of get_frame that does this:

#include "avisynth_c.h"

AVS_VideoFrame* AVSC_CC InvertNeg_get_frame(AVS_FilterInfo* fi, int n)
{
AVS_VideoFrame* src;
int row_size, height, src_pitch;
BYTE* srcp;
int x, y, p;

int planes[] = {AVS_PLANAR_Y, AVS_PLANAR_V, AVS_PLANAR_U};

src = avs_get_frame(fi->child, n);
avs_make_writable(fi->env, &src);

for (p=0; p<3; p++) {
srcp = avs_get_write_ptr_p(src, planes[p]);
src_pitch = avs_get_pitch_p(src, planes[p]);
row_size = avs_get_row_size_p(src, planes[p]);
height = avs_get_height_p(src, planes[p]);

for (y = 0; y < height; y++) {
for (x = 0; x < row_size; x++) {
srcp[x] = srcp[x] ^ 255; // or srcp[x] =^ 255;
}
srcp += src_pitch;
}
}

return src;
}

AVS_Value AVSC_CC Create_InvertNeg(AVS_ScriptEnvironment* env, AVS_Value args, void* user_data)
{
AVS_Value v;
AVS_FilterInfo* fi;
AVS_Clip* new_clip = avs_new_c_filter(env, &fi, avs_array_elt(args, 0), 1);

if (!avs_is_planar(&fi->vi) || !avs_is_yuv(&fi->vi)) {
v = avs_new_value_error("InvertNeg: planar YUV data only!");
} else {
fi->get_frame = InvertNeg_get_frame;
v = avs_new_value_clip(new_clip);
}

avs_release_clip(new_clip);
return v;
}

const char* AVSC_CC avisynth_c_plugin_init(AVS_ScriptEnvironment * env)
{
avs_add_function(env, "InvertNeg", "c", Create_InvertNeg, 0);
return "InvertNeg sample c-plugin";
}

The key difference between this version of the function and the original version is the presence of the avs_make_writable callback. This is necessary because this time "we don't know where that source frame has been." Someone else in the filter chain may be holding a reference to it, in which case we won't be allowed to write to it.

Filter SDK/CInvertNeg

2017-01-13T22:30:28Z

Admin: /* Line by line breakdown */

I'll start off with a complete, working Avisynth C plugin. It's called "InvertNeg", and it produces a photo-negative of the input clip.

Here's InvertNeg.c:

#include "avisynth_c.h"

AVS_VideoFrame* AVSC_CC InvertNeg_get_frame(AVS_FilterInfo* fi, int n)
{
AVS_VideoFrame* src;
AVS_VideoFrame* dst;
int row_size, height, src_pitch, dst_pitch;
const BYTE* srcp;
BYTE* dstp;
int x, y, p;

int planes[] = {AVS_PLANAR_Y, AVS_PLANAR_V, AVS_PLANAR_U};

src = avs_get_frame(fi->child, n);
dst = avs_new_video_frame(fi->env, &fi->vi);

for (p=0; p<3; p++) {
srcp = avs_get_read_ptr_p(src, planes[p]);
dstp = avs_get_write_ptr_p(dst, planes[p]);
src_pitch = avs_get_pitch_p(src, planes[p]);
dst_pitch = avs_get_pitch_p(dst, planes[p]);
row_size = avs_get_row_size_p(dst, planes[p]);
height = avs_get_height_p(dst, planes[p]);

for (y = 0; y < height; y++) {
for (x = 0; x < row_size; x++) {
dstp[x] = srcp[x] ^ 255;
}
srcp += src_pitch;
dstp += dst_pitch;
}
}

avs_release_video_frame(src);
return dst;
}

AVS_Value AVSC_CC Create_InvertNeg(AVS_ScriptEnvironment* env, AVS_Value args, void* user_data)
{
AVS_Value v;
AVS_FilterInfo* fi;
AVS_Clip* new_clip = avs_new_c_filter(env, &fi, avs_array_elt(args, 0), 1);

if (!avs_is_planar(&fi->vi) || !avs_is_yuv(&fi->vi)) {
return avs_new_value_error("InvertNeg: planar YUV data only!");
}

fi->get_frame = InvertNeg_get_frame;

v = avs_new_value_clip(new_clip);

avs_release_clip(new_clip);
return v;
}

const char* AVSC_CC avisynth_c_plugin_init(AVS_ScriptEnvironment * env)
{
avs_add_function(env, "InvertNeg", "c", Create_InvertNeg, 0);
return "InvertNeg sample c-plugin";
}

Link to avisynth.lib and when using the MSVC++ compiler add the definition file. Compile this file into a DLL named InvertNeg.dll. See [[Filter_SDK/Compiling_instructions|compiling instructions]]. Now create an Avisynth script which looks something like this:

LoadCPlugin("d:\path\InvertNeg.dll")
clip = BlankClip().ConvertToYV12()
return clip.InvertNeg()

=== Line by line breakdown ===

Here's a line-by-line breakdown of InvertNeg.c:

#include "avisynth_c.h"

This header declares all the classes and miscellaneous constants that you might need when writing a plugin. All external plugins should #include it.

External plugins do not link with avisynth.dll, so they can't directly access functions that are defined in the main Avisynth source code. Therefore, every important function in avisynth_c.h is either defined inline or (???).

AVS_VideoFrame* AVSC_CC InvertNeg_get_frame(AVS_FilterInfo* fi, int n)

This function is the main callback functions for our filter. When called it should return frame n. It returns this frame as a pointer to AVS_VideoFrame.

AVSC_CC stands for Avisynth calling convention. Right now it is stdcall (it used to be cdecl when the C interface was exposes through seperate plugin). By using AVSC_CC you should be able to maintain source code compatibility when the calling convention changes.

AVS_VideoFrame* src;
AVS_VideoFrame* dst;
int row_size, height, src_pitch, dst_pitch;
const BYTE* srcp;
BYTE* dstp;
int x, y, p;

Declaring all of the variables we will need '''must be done up front''' (for the C++ plugin this is not necessary). Doing it in between the code will get you strange compile errors.

int planes[] = {AVS_PLANAR_Y, AVS_PLANAR_V, AVS_PLANAR_U};

The plugin requires planar YUV data, so we need to process the planes. Note the constants (such as AVS_PLANAR_Y) are the same as the ones in the C++ inteface, except for the 'AVS_' in front of it.

src = avs_get_frame(fi->child, n);

"child" is a member of AVS_FilterInfo, of type AVS_Clip. It generally contains the clip that was passed into the filter. For our filter to produce frame n we need the corresponding frame of the input clip. If you need a different frame from the input, all you have to do is pass a different frame number get_frame.

Note the functions (such as avs_get_frame) are similar as the ones in the C++ inteface, except for the 'avs_' in front of it.

get_frame calls are usually intercepted by Avisynth's internal caching code, so the frame request may never actually reach the child filter (meaning ???).

dst = avs_new_video_frame(fi->env, &fi->vi);

The avs_new_video_frame function allocates space for a video frame of the supplied size. (In this case it will hold our filter's output.) The frame buffer is uninitialized raw memory.

"env" is a member of AVS_FilterInfo which is a pointer to AVS_ScriptEnvironment. One instance of AVS_ScriptEnvironment is created for each AVS script.

"vi" is another member of AVS_FilterInfo. It is a structure of type AVS_VideoInfo, which contains information about the clip (like frame size, frame rate, pixel format, audio sample rate, etc.). avs_new_video_frame uses the information in this structure to return a frame buffer of the appropriate size.

Frame buffers are reused once all references to them go away. So usually memory won't need to be allocated from the heap.

for (p=0; p<3; p++) {

Loop over all planes.

srcp = avs_get_read_ptr_p(src, planes[p]);
dstp = avs_get_write_ptr_p(dst, planes[p]);

All frame buffers are readable, but not all are writable.

The rule about writability is this: A buffer is writable if and only if its reference count is one. In other words, you can only write to a buffer if no one else might be reading it. This rule guarantees that as long as you hold on to a video frame and don't write to it yourself, that frame will remain unchanged. Any buffer you get from avs_new_video_frame is guaranteed to be writable. However, frames you get from other clips via get_frame may not be writable, in which case avs_get_write_ptr will return a null pointer.

There is an is_writable method which you can call to find out if a buffer is writable or not, and there's a avs_make_writable method (described below) to ensure that it is.

src_pitch = avs_get_pitch_p(src, planes[p]);
dst_pitch = avs_get_pitch_p(dst, planes[p]);

The "pitch" of a frame buffer is the offset (in bytes) from the beginning of one scan line to the beginning of the next. The source and destination buffers won't necessarily have the same pitch.

Buffers created by avs_new_video_frame are always double word (16-byte) aligned and always have a pitch that is a multiple of 16.

row_size = avs_get_row_size_p(dst, planes[p]);

The row size is the length of each row in bytes (not pixels). It's usually equal to the pitch or slightly less, but it may be significantly less if the frame in question has been through Crop.

Since our source and destination frames have the same width and pixel format, they will always have the same row size. Thus I only need one row_size variable, and I could just as well have used dest instead of src.

height = avs_get_height_p(dst, planes[p]);

The height is the height in pixels. Again, for our filter this is the same for the source and the destination.

for (y = 0; y < height; y++) {
for (x = 0; x < row_size; x++) {
dstp[x] = srcp[x] ^ 255;
}
srcp += src_pitch;
dstp += dst_pitch;
}
}

This is the code that does the actual work. The "srcp += src_pitch; dstp += dest_pitch;" idiom is a useful way of dealing with potentially differing pitches without too much grief.

avs_release_video_frame(src);

Once we are done with a video frame it needs to be released. Releasing a video frame does not actually delete it but decrements the reference count.

return dst;

GetFrame returns the newly-created frame.

AVS_Value AVSC_CC Create_InvertNeg(AVS_ScriptEnvironment* env, AVS_Value args, void* user_data)

In order to use our new filter, we need a scripting-language function which creates an instance of it. This is that function.

Script functions written in C take three arguments. env contains the same ScriptEnvironment pointer that will later be passed to GetFrame. args contais all the arguments passed to the function by the script. user_data contains the void pointer which you passed to AddFunction (see below). Usually you won't need this.

AVS_Value is a variant type which can hold any one of the following: a boolean value (true/false); an integer; a floating-point number; a string; a video clip; an array of AVS_Values; or nothing ("undefined"). You can test which one it is with the methods avs_is_bool, avs_is_int, avs_is_float, avs_is_string, avs_is_clip, avs_is_array, and avs_defined (which returns true if the AVS_Value is not "undefined"). You can get the value with avs_as_bool, avs_as_int, etc. for arrays, you can use the avs_array_size method to get the number of elements, and avs_array_elt get the elements themselves. For convenience, avs_is_float and avs_as_float will work with integers also. But boolean values are not treated as numeric (unlike C).

The name "Create_InvertNeg" is arbitrary. This function will actually be known as "InvertNeg" in scripts, because that's the name we pass to avs_add_function below.

AVS_Value v;

v will serve as the return value.

AVS_FilterInfo* fi;
AVS_Clip* new_clip = avs_new_c_filter(env, &fi, avs_array_elt(args, 0), 1);

"avs_new_c_filter" creates a new filter. AVS_Clip is an abstract type representing a filter. In this case it will represent our new filter. "env" is the current script environment. "fi" will be set to point to our filter AVS_FilterInfo which is the concrete representation of a C filter. We will modify this structure later. "avs_array_elt(args, 0)" is accessing the first value of args, which is generally the parent clip. The last parameter, is a boolean value "store_child". It should generally always be set to true.

if (!avs_is_planar(&fi->vi) || !avs_is_yuv(&fi->vi)) {
return avs_new_value_error("InvertNeg: planar YUV data only!");
}

Our filter will not work unless the video is stored as YUV planar. If this is not the case than an error is returned.

fi->get_frame = InvertNeg_get_frame;

Here we are setting the get_frame callback. There are other callbacks (like get_audio, set_cache_hints and get_parity), but since "store_child" was set to true we do not have to worry about implementing all of them. Just the ones we need.

v = avs_new_value_clip(new_clip);

The return value is then set to the new clip returned by avs_new_c_filter. avs_new_value_clip stores the clip in an AVS_Value which will be returned by our Create_InvertNeg. It also creates a new reference to the clip.

avs_release_clip(new_clip);

We must now release the clip returned by avs_new_c_filter. In the case of an error the clip is no longer needed. Otherwise a new reference is created to the clip with avs_new_value_clip so we must release the original reference.

return v;

Finally we return. "v" is either an error or the new clip.

const char* AVSC_CC avisynth_c_plugin_init(AVS_ScriptEnvironment * env)

This is the only function which gets exported from the DLL. It is called by the script function LoadCPlugin the first time this plugin in loaded in a particular script. If several scripts are open at once and more than one of them loads this plugin, avisynth_c_plugin_init may be called more than once with different ScriptEnvironments. Therefore:

* You should not save the env parameter in a global variable.
* If you need to initialize any static data, you should do it in DLLMain, not in this function.

The main purpose of the avisynth_c_plugin_init function is to call avs_add_function.

avs_add_function(env, "InvertNeg", "c", Create_InvertNeg, 0);

As promised, we now call add_function to let Avisynth know of the existence of our filter. This function takes four arguments: the name of the new script function; the parameter-type string; the C function implementing the script function; and the user_data cookie.

The parameter type string specifies the paramaters for the function. The return value is untyped. It consists of a series of letters specinging the parameter types with 'c' for clip, 'i' for integer, 's' for string, 'b' for boolean, and 'f' for float. In addition:

* Any type can be followed with a '*' or '+' to indicate "zero or more" or "one or more" respectively. In this case all the matching arguments will be gathered into a sub-array. For example, if your type string is "is+f", then the integer argument will be args[0], the string arguments will be args[1][0], args[1][1], etc. (and there will be avs_array_size(args[1]) of them), and the float argument will be args[2].
* '.' matches a single argument of any type. To match multiple arguments of any type, use ".*" or ".+".
* Named arguments can be specified in [brackets] before the type. Named arguments are also optional arguments; if the user omits them, they will be of the undefined type instead of the type you specify.

return "InvertNeg sample c-plugin";

The return value of avisynth_c_plugin_init is a string which can contain any message you like, such as a notice identifying the version and author of the plugin. This string becomes the return value of LoadCPlugin, and will almost always be ignored. You can also just return 0 if you prefer.

== As an in-place filter ==

The InvertNeg filter could easily do its work in a single buffer, rather than copying from one buffer to another. Here's a new implementation of get_frame that does this:

#include "avisynth_c.h"

AVS_VideoFrame* AVSC_CC InvertNeg_get_frame(AVS_FilterInfo* fi, int n)
{
AVS_VideoFrame* src;
int row_size, height, src_pitch;
BYTE* srcp;
int x, y, p;

int planes[] = {AVS_PLANAR_Y, AVS_PLANAR_V, AVS_PLANAR_U};

src = avs_get_frame(fi->child, n);
avs_make_writable(fi->env, &src);

for (p=0; p<3; p++) {
srcp = avs_get_write_ptr_p(src, planes[p]);
src_pitch = avs_get_pitch_p(src, planes[p]);
row_size = avs_get_row_size_p(src, planes[p]);
height = avs_get_height_p(src, planes[p]);

for (y = 0; y < height; y++) {
for (x = 0; x < row_size; x++) {
srcp[x] = srcp[x] ^ 255; // or srcp[x] =^ 255;
}
srcp += src_pitch;
}
}

return src;
}

AVS_Value AVSC_CC Create_InvertNeg(AVS_ScriptEnvironment* env, AVS_Value args, void* user_data)
{
AVS_Value v;
AVS_FilterInfo* fi;
AVS_Clip* new_clip = avs_new_c_filter(env, &fi, avs_array_elt(args, 0), 1);

if (!avs_is_planar(&fi->vi) || !avs_is_yuv(&fi->vi)) {
v = avs_new_value_error("InvertNeg: planar YUV data only!");
} else {
fi->get_frame = InvertNeg_get_frame;
v = avs_new_value_clip(new_clip);
}

avs_release_clip(new_clip);
return v;
}

const char* AVSC_CC avisynth_c_plugin_init(AVS_ScriptEnvironment * env)
{
avs_add_function(env, "InvertNeg", "c", Create_InvertNeg, 0);
return "InvertNeg sample c-plugin";
}

The key difference between this version of the function and the original version is the presence of the avs_make_writable callback. This is necessary because this time "we don't know where that source frame has been." Someone else in the filter chain may be holding a reference to it, in which case we won't be allowed to write to it.
