Avs2YUV

Latest revision as of 21:57, 5 March 2020

[edit] Description

Avs2YUV is a command-line program, originally intended for use under 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.

[edit] Requirements

AviSynth 2.6.0 or greater | AviSynth+

• Supported color formats: Y8, YV12, YV16, YV24

[edit] Usage

Usage: avs2yuv [options] in.avs [-o out.y4m] [-o out2.y4m] [-hfyu out.avi]

-v      print the frame number after processing each frame
-seek   seek to the given frame number
-frames stop after processing this many frames
-slave  read a list of frame numbers from stdin (one per line)
-no-mt  disable detection of AviSynth MT which adds Distributor()
-raw    output raw I400/I420/I422/I444 instead of yuv4mpeg
-csp    convert to I400/I420/I422/I444 or AUTO colorspace (default I420)
-depth  specify input bit depth (default 8)
-fps    overwrite input framerate
-par    specify pixel aspect ratio

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

v0.24bm6     06/30/2019      - BugMaster's mod 6
                             - 4:0:0 (monochrome) output support

v0.24bm5     08/18/2016      - BugMaster's mod 5
                             - minor fixes

v0.24bm4     08/18/2016      - BugMaster's mod 4
                             - new option: -no-mt  disable detection of AviSynth MT which adds Distributor()
                             - support for AviSynth+ high bit-depth pixel formats

v0.24bm3     09/04/2014      - BugMaster's mod 3
                             - new options:
                               -depth specify input bit depth (default 8), >8 expects AviSynth 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

v0.24bm2     09/20/2011      - BugMaster's mod 2
                             - merge 2 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)

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

v0.24        03/04/2005      - new option: -raw outputs raw I420 (omits yuv4mpeg headers)

v0.23        01/26/2005      - new option: -slave takes a list of frames to decode

v0.22        11/25/2004      - fixed a bug when -frames comes before -seek on the command line

v0.21        11/22/2004      - write to multiple output streams

                             - huffyuv preset (doesn't work under wine)

v0.20        11/22/2004      - prints avisynth error messages instead of crashing
                             - no longer requires avisynth_c.dll

v0.13        11/10/2004      - binmode stdout again

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

v0.11        10/31/2004      - binmode stdout (may or may not fix some piping problems)
