== Description ==
Avs2YUV is a command-line program, originally intended for use under [http://en.wikipedia.org/wiki/Wine_%28software%29 Wine], to interface between AviSynth and Linux-based video tools. Nowadays is commonly used to pipe video (including high bit depth) to encoders like x264, x265, and FFmpeg/Libav. An advantage of using Avs2YUV is that one can pipe from a 32-bit AviSynth to 64-bit applications.
<br>
<br>

== Requirements ==
[http://sourceforge.net/projects/avisynth2/ AviSynth 2.6.0] or greater | [[AviSynth+]]
* Supported color formats: [[Y8]], [[YV12]], [[YV16]], [[YV24]]
<br>

== Usage ==
 Usage: avs2yuv [options] in.avs [-o out.y4m] [-o out2.y4m] [-hfyu out.avi]<br>
 {{Template:FuncDef|-v}}      print the frame number after processing each frame
 {{Template:FuncDef|-seek}}   seek to the given frame number
 {{Template:FuncDef|-frames}} stop after processing this many frames
 {{Template:FuncDef|-slave}}  read a list of frame numbers from stdin (one per line)
 {{Template:FuncDef|-no-mt}}  disable detection of AviSynth MT which adds Distributor()
 {{Template:FuncDef|-raw}}    output raw I400/I420/I422/I444 instead of yuv4mpeg
 {{Template:FuncDef|-csp}}    convert to I400/I420/I422/I444 or AUTO colorspace (default I420)
 {{Template:FuncDef|-depth}}  specify input bit depth (default 8)
 {{Template:FuncDef|-fps}}    overwrite input framerate
 {{Template:FuncDef|-par}}    specify pixel aspect ratio<br>
 The outfile may be "-", meaning stdout.
 Output format is yuv4mpeg, as used by MPlayer, FFmpeg, Libav, x264, mjpegtools.
 Huffyuv output requires ffmpeg, and probably doesn't work in Wine.

 Version      Date            Changes<br>
 v0.24bm6     06/30/2019      - BugMaster's mod 6
                              - 4:0:0 (monochrome) output support<br>
 v0.24bm5     08/18/2016      - BugMaster's mod 5
                              - minor fixes<br>
 v0.24bm4     08/18/2016      - BugMaster's mod 4
                              - new option: -no-mt  disable detection of AviSynth MT which adds Distributor()
                              - support for [[Avisynthplus_color_formats|AviSynth+ high bit-depth pixel formats]]<br>
 v0.24bm3     09/04/2014      - BugMaster's mod 3
                              - new options:
                                -depth specify input bit depth (default 8), >8 expects AviSynth [[Stack16|16-bit hack]] input video
                                -fps overwrite input framerate
                                -par specify pixel aspect ratio
                              - new supported value AUTO for -csp option which will try to detect input colorspace or convert to I420<br>
 v0.24bm2     09/20/2011      - BugMaster's mod 2
                              - merge 2 [http://github.com/chikuzen/avs2yuv changes by Oka Motofumi] (aka Chikuzen):
                              - added 128 KB file buffering for speed up
                              - use ffmpeg for huffyuv encoding instead of mencoder
                              - added support for interlaced avs sources (it must be field-based instead of frame-based)
                              - new option: -csp i420/i422/i444 for support of I422/I444 colorspaces output (AviSynth 2.6+ is required)<br>
 v0.24bm1     07/07/2011      - BugMaster's mod
                              - replaced AviSynth C++ interface with C interface
                              - compiles with GCC instead of MSVS
                              - added call of 'Distributor' for multi-threaded scripts
                              - calls avs_delete_script_environment at the end of work<br>
 v0.24        03/04/2005      - new option: -raw outputs raw I420 (omits yuv4mpeg headers)<br>
 v0.23        01/26/2005      - new option: -slave takes a list of frames to decode<br>
 v0.22        11/25/2004      - fixed a bug when -frames comes before -seek on the command line<br>
 v0.21        11/22/2004      - write to multiple output streams<br>
                              - huffyuv preset (doesn't work under wine)<br>
 v0.20        11/22/2004      - prints avisynth error messages instead of crashing
                              - no longer requires avisynth_c.dll<br>
 v0.13        11/10/2004      - binmode stdout again<br>
 v0.12        11/09/2004      - reduced memory footprint
                              - no longer requires that avisynth be installed; merely having the dlls is enough
                              - fixed a possible crash on exit<br>
 v0.11        10/31/2004      - binmode stdout (may or may not fix some piping problems)<br>
