don't sweat the audio too much - we can strip that out just fine with quicktime player. i noticed ffmpeg doesn't handle anything but stereo particularly well, so i guess it's a grey area in mov's specs or something (6 or 4 channel movs are hellish to demux with anything but QT player). and TMPG's qtreader passes everything as 44.1k and crashes on audio...
one thing i'm interested in is returning something other than RGB, because i've yet to be able to do that with DSS or (obviously) Qtreader.vfp. ffmpeg does it okay, but that requires an intermediate avi file, which defeats the purpose of avisynth somewhat. at work i've been getting an increasing number of blackmagic movs, and would rather not go uyvy to RGB to yv12 if i can help it
. if it's me doing the capping i use avi, but not everyone does that...
[edit]
but don't let this hijack your OMF plugin. movsource should really get its own thread if it's going to happen...
