mplayer fails to play dirac in ogg file

[hanno@…]

mplayer seems to be unable to play dirac streams in ogg files. A bit odd, as ogg is the common container for dirac.

The other sample provided there (quicktime container) plays fine.

Tested with latest mplayer svn and both dirac and schroedinger support enabled.

I wonder why noone has answered here.
The bug is still valid.
Dirac neither works "ootb" in an ogg container nor in a ts container.

Testfiles:
ogg:

ts:

The "workaround" is using -demuxer lavf with mplayer. Then it plays fine. But it should be autodetected and not only giving the message "NO VIDEO!".

The solution should not only be found with google in the mailing list archive:

where there is no final answer since nearly two years.

Fixed by making the lavf ogg demuxer the default.
Adding support for new formats for ogg is a huge pain/effort (which is one of the reasons why ogg is generally hated among most developers), so there is no real chance for it to be added to the native demuxer, and some of the issues with the lavf one were only recently fixed.
The situation is basically the same for TS, except that there are probably still more issues left to fix before we can switch, though it might be reasonably easy to add dirac support.
Either way, dirac is of so little relevance it's barely worth any effort, patches however are welcome...

The dirac-in-TS is also working now, though quite hackish/experimental.
