[MPlayer-advusers] mkv demuxer bug: no stream recognized

[Attila Kinali]

Moin,

I just stumbled over a bug in the mkv demuxer of MPlayer:

MPlayer is unable to detect any streams within the file:

---schnipp---
$ mplayer mkv_no_stream_found.mkv -v
MPlayer dev-SVN-r19650-4.1.2 (C) 2000-2006 MPlayer Team
[...]
Playing mkv_no_stream_found.mkv.
