[FFmpeg-devel] [PATCH] avformat: avisynth demuxer rewrite

Dear ffmpeg-devel,

The current Avisynth demuxer is misnamed; rather, it would be more
appropriately described as a VfW demuxer. This email contains a
rewrite of the demuxer that uses the Avisynth library directly, with
the following benefits:

1) useful error messages instead of video clips with error text
2) no dependency on VfW, and hence no requirement for the related SDKs/libraries
3) able to support AvxSynth (https://github.com/avxsynth/avxsynth/wiki) on Linux

I have tested the demuxer on both Windows and Linux and verified that
I was able to ffprobe YV12, YUY2, and RGB32 scripts as well as encode
them to rawvideo.

Review and comments would be appreciated.
