[MPlayer-users] mkv demuxer dying at certain places in file

[Robert Henney]

I've run across a file that seems to confuse the matroska demuxer enough
that it will appear to abort when reaching certain points in the file.
seeking past these points gets around the problem, as well as using the
lavf demuxer.

using the lavf demuxer, though it allows the file to play fine, does
provide what might be clues.  at the times the matroska demuxer would
abort, the lavf demuxer prints "Unknown entry 0xbf in cluster data".
Not sure what exactly that indicates though.  I do not believe that 
the file is corrupt.

I made the file available at http://rut.org/mplayer/
The times where these problems occur are at 0:53 and 1:08.
