[MPlayer-users] [BUG] Can't play DVDs with ffmpeg12

[Carlos Laviola]

Hello,

When trying to play DVD titles with -vc ffmpeg12, mplayer crashes.  I
have debugged mplayer as told by the documentation, for reproducible
crashes (this happens to me every time, and with more than one DVD).
I've done exactly what is told on "How to conserve information about a
reproducible crash".  Hope I've done everything right, but if there's
need for more info, I can supply it, of course.

The exact command line is:
mplayer -vc ffmpeg12 -dvd 4

Note that the DVD really plays just fine with mpeg12, but I'm told this
is much slower than libavcodec's video codec.
