Good stuff.

Hmm, I think that showing a message, or even erroring when only an audio
stream isn't available is a bad idea. Don't go put policy in the
framework, we'd really need a way to the backend to check whether or not
the audio and/or video is supported, and whether audio and/or video is

The current version of Totem-xine only errors if the video can't be
played for a video file, and if the audio is unsupported for an
audio-only file.

Even better is keeping a list of known crasher/problematic streams, and
regression test those. Launch Totem with a playlist of streams during
the night, and watch the crashes/hangs back in the morning.


I'm happy to see there is work being done on getting the GStreamer
backend better. I must tell you that the xine backend still isn't fully
finished (as seen in the error handling changes recently, the bug fixes,
etc.), and there are a lot more things to be done to support multiple
backends easily (like being able to tell whether or not such and such
backend supports a particular feature).
