I have one official disk of DAFEG (german deaf society), one of videos from disk disk i snot working with totem or gst-launch, but it is working with vlc or mpalyer. I assume it is a bug in gst-libav, but may be i'm wrong. Link to affected file: https://www.dropbox.com/s/ca7ul5etcwamarc/gottes.mov
Apparently there is an extra 4 bytes of 0 inside the svq3 stsd atom that was causing qtdemux to busy loop as it would read that as a 0 size atom. I added a check for size=0 -> abort and now it plays. It looks like a poorly generated file, but still playable.
