Avs2pipemod

Latest revision as of 04:27, 20 August 2019

[edit] Description

Given an AviSynth script as input, avs2pipemod can send video, audio, or information of various types to stdout for consumption by command-line encoders or other tools. It is a continued development of avs2pipe. Thanks to Chris Beswick for releasing avs2pipe under GPL 3.0.

[edit] Differences compared to the original:

• Display total elapsed time.
• contents of 'info'
• New option 'benchmark'.
• New option 'trim'.
• New option 'x264raw'
• New option 'dumptxt'
• 'y4mp', 'y4mt', 'y4mb' and 'rawvideo' options instead of 'video'.
• FieldBased input will be corrected to framebased on yuv4mpeg2 output modes.
• Colorspace conversion that takes colormatrix and interlace into consideration.
• 'wav', 'extwav' and 'rawaudio' option instead of 'audio'.
• Convert bit depth function in audio output mode.
• Only the compilation with mingw/msys is supported.

[edit] Requirements

• AviSynth 2.6.0 or greater
• Supported color formats: Y8, YV12, YV16, YV24, YV411

[edit] Usage

avs2pipemod  ver 1.1.1
built on Aug 15 2016 00:32:12

Usage: avs2pipemod [option] input.avs
  e.g. avs2pipemod -wav=24bit input.avs > output.wav
       avs2pipemod -y4mt=10:11 input.avs | x264 - --demuxer y4m -o tff.mkv
       avs2pipemod -rawvideo -trim=1000,0 input.avs > output.yuv

   -wav[=8bit|16bit|24bit|32bit|float  default unset]
        output wav format audio(WAVEFORMATEX) to stdout.
        if optional arg is set, audio sample type of input will be converted
        to specified value.

   -extwav[=8bit|16bit|24bit|32bit|float  default unset]
        output wav extensible format audio(WAVEFORMATEXTENSIBLE) containing
        channel-mask to stdout.
        if optional arg is set, audio sample type of input will be converted
        to specified value.

   -rawaudio[=8bit|16bit|24bit|32bit|float  default unset]
        output raw pcm audio(without any header) to stdout.
        if optional arg is set, audio sample type of input will be converted
        to specified value.

   -y4mp[=sar  default 0:0]
        output yuv4mpeg2 format video to stdout as progressive.
   -y4mt[=sar  default 0:0]
        output yuv4mpeg2 format video to stdout as tff interlaced.
   -y4mb[=sar  default 0:0]
        output yuv4mpeg2 format video to stdout as bff interlaced.

   -rawvideo[=vflip default unset]
        output rawvideo(without any header) to stdout.

   -info  - output information about aviscript clip.

   -filters - output external plugin filters/functions list to stdout.

   -benchmark - do benchmark avs script, and output results to stdout.

   -dumptxt - dump pixel values as tab separated text to stdout.

   -trim[=first_frame,last_frame  default 0,0]
        add Trim(first_frame,last_frame) to input script.
        in info, this option is ignored.

   -dll[=path to avisynth.dll  default "avisynth"] specify which avisynth .dll is used.
note1 : in yuv4mpeg2 output mode, RGB input that has 720pix height or more
        will be converted to YUV with Rec.709 coefficients instead of Rec.601.

note2 : in fact, it is a spec violation to use WAVEFORMATEX(-wav option)
        except 8bit/16bit PCM.
        however, there are some applications that accept such invalid files
        instead of supporting WAVEFORMATEXTENSIBLE.

note3 : '-extwav' supports only general speaker positions.
