I released a new version of the the GStreamer FFmpeg plugin today. Try it today!
Disc content detection:
Wrote some code (similar to the code in gnome-volume-control, in hindsight) to detect the type of disc that the user is opening in his favourite movie player. Didn't commit, mainly because the audio CD input plugin in GStreamer is giving me headaches, as in: it eats my memory, it fails to play and if it doesn't do that, it just crashes.
