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.

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.



avs2pipemod  ver 1.0.0
built on Jul 10 2016 14:14:38
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.
-benchmark - do benchmark aviscript, 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.
-y4mbits[=9/10/12/14/16 default 16] specify true bit depth of YUV4XXP16 this option is available only at the time of Y4M output
-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.
