Better implement the subtitle support (and fix whatever other shortcomings/bugs it may have) for the lavf demuxer and make that one the default.

It appears that libavformat doesn't implement subtitle reading on OGG, so the lavf demuxer can't do the subtitle magic. I'll file a bug on ffmpeg (if it isn't filed already).
Since it is better to avoid code duplication, I'll set this to WONTFIX and see what happens on lavf. After it is fixed, we set it as the default for ogg.

Well, it is not code duplication as such, but it will be wasted time since we will switch all demuxers to lavf code in the long run.
You do not need to report the missing text subtitle support, I sent a patch for that.
But report if you have problems with text subtitles with that patch or if you have some other subtitles (I heard rumors about vobsub in ogg, but I have no samples).
There is at least one remaining issue with the lavf ogg demuxer, it does not display a language name for the subtitles.

Well, when you wrote that I had already sent a report to the libav* maling list. Oh well, if it doesn't do any good at least it won't do any evil.
I will set lavf as the default demuxer on my working copy and see what's up on lavf. I'm new to DSP and media, so I'm a bit lost on libavformat code, but I'll try to figure it out.

libavformat code should be much simpler to understand that our demuxer.
Anyway, subtitle support is in now, support for displaying track language is pending but may not be accepted since this feature was never properly specified.
If you have problems with ogg lavf demuxer, report them.
I'm having the same problem.
I saw on the source code that the code to change audio on OGG/OGM is simply not implemented. I'll give a shot at implementing it.
