Incorrect and Incorrect.  The mplayer team (of which the ffmpeg
project is a part) have a long-running vendetta against Ogg, part of
which is a long list of things they incorrectly claim Ogg can't do.
Their position is that the only acceptable strategy is to completely
abandon Ogg for their (practically entirely equivalent) .nut format or
they're going to take their toys and go home, which they've partially
done by refusing to implement Ogg support in any meaningful way.

The developer culture there seems more interested in complaining about patches.

Well, it's very ogg-specific.  Personally I use mplayer for alot of
conversion tasks and have hacked a mode into mine to bolt it to the
Theora example encoder.  Unfortunately, mplayer/mencoder are a bit too
buggy to just hand out the patch and recommend people use it.  Too
much functionality is subtly broken or outright nonfunctional in all
but a narrow range of uses, and those bugs would get blamed on us.

See above.  It's never going to happen.  The project has the
equivalent of five or six full-blown Joerg Schillings.

That said, we need to do a better job with our own tools if we can't
rely on the mplayer folks.
