Filter SDK

Revision as of 13:08, 10 May 2013

AviSynth external Filter SDK is a package for developers to create your own filters (plugins) for AviSynth.

The package consists of:

• this documentation text files (in HTML or Wiki format);
• the header file 'avisynth.h' (recent version) with all declarations to include in plugin source code;
• SimpleSample plugin source codes;
• may be some extra files in 'Extra' folder.

You must have some necessary software.

Ben's AviSynth Docs is the documentation written for AviSynth 1.0 by Ben Rudiak-Gould, in its original form.

See more about the modifications for AviSynth 2.5 in the AviSynth Two-Five SDK.

Also, Simple sample has some very simple examples covering development of a filter that does virtually nothing through to one that draws a variable sized square, in the middle of the screen, in all Color spaces.

One thing not covered in Simple sample, is how to change frame size in a filter. Also have a look at Getting started with Audio.

See Non-clip sample how to create runtime AviSynth functions.

There are several different Colorspaces in AviSynth. See more information about Color spaces and Working with Images.

Read more about the Internal Functions in AviSynth.

You can also browse various topic on Assembler Optimizing.

Once you've got the basics down on AVS development (Ben's text is quite good), the SDK for VirtualDub is also a good read. Good news is you won't have to worry about writing function pointers and raw Win32; meanwhile, Avery knows his stuff when it comes to video & CPU optimization techniques, so you better pay attention.

Some video related ebooks (PDF) can be downloaded freely from Snell & Wilcox.

Please read AviSynth SDK History.
