While ffmpeg2theora is the topic... does anyone have some hints on which
formats to use for conversion source (avi, mpeg, or what? which codecs?). A
colleague of mine did some tests converting with ffmpeg2theora recently and
we tried playing that back in our application, using theora reference
decoder, but some of the files played back erratically. The library reported
that video bitrate was 0. Though it did play, it blocked on some frames,
then ffwd-ed quickly etc. Does anyone know what may be the reason for such
