avs2pipe is a tool to output y4m video, wav audio, dump some info about the input avs clip or suggest x264 blu-ray encoding settings. Usage: avs2pipe [audio|video|info|x264] input.avs audio - output wav extensible format audio to stdout. video - output yuv4mpeg2 format video to stdout. info - output information about aviscript clip. x264bd - suggest x264 arguments for blu-ray disc encoding. It simply takes a path to an avs script that returns a clip with audio and/or video and outputs it as a y4m (--video) or wav (--audio) stream to stdout. It can also generate information about the clip (--info) in an easily parsable format for gui's. The advantage of avs2pipe over other solutions, other than it doing multiple things in one and supporting more colorspaces is that it links directly with avisynth.dll via the C interface, so it compiles with both Visual Studio and MinGW and when used with wine in linux simply requires that the avisynth dll's are in PATH, so no need to have vfw configured correctly. Also as it uses WAVE_FORMAT_EXTENSIBLE for wav output and directly takes data from avisynth it will output exactly the same data as avisynth uses internally. Source is provided in the src folder and is released under the GPL-3.0. In addition to the source is: src\avisynth25 - header and link lib from AviSynth 2.5.8 src\avisynth26 - header from http://git.videolan.org/?p=x264.git;a=blob;f=extras/avisynth_c.h;hb=HEAD link lib from AviSynth AVS 2.6.0 Alpha 2 [090927] Projects and scripts to build the source are located in: vs2010 - Project for Visual Studio 2010 Express mingw - Batch file MinGW on Windows, sh script for MinGW under Linux The YUV4MPEG2 output is inspired by Avs2YUV by Loren Merritt, it is basically the same method, converted from C++ to C. The changes are: Interlaced Support - Picks up the flags for interlaced content from AssumeFieldBased(), AssumeTFF() etc. and will pass this on to programs such as x264 eliminating the need to add flags to the encoder command. Extended Color Spaces - Thanks to Chikuzen when compiled against AviSynth 2.6 there is support for a whole host of extra colorspaces. The WAV output is coded from scratch using specs from "the internet" and so could be full of problems, altho I have not found any in testing yet.
