[MPlayer-users] Two Bugs when playing Matroska Video Files

Hi,
hey - my first mail to the mplayer mailing list and two bugs to report!
;) No, mplayer is great software, but maybe we can get these things
below fixed. :) I use the current CVS version, by the way. If I did
something wrong in this bug report, please tell me. :)
I get a crash (sig11) when trying to play a selfencoded Matroska Video
File, containing video captured from DVB-s. Audio is the original MPEG-2
192 kbps stream from DVB, Video is reencoded XviD dev-api-4 from cvs.
I muxed the file in Windows using AVI-Mux GUI 1.16.4. The crash does not
happen when I try to playback a MKV file created with VirtualDubMod,
which contains a different movie, but also the original MPEG-2 192 kbps
stream from DVB and reencoded XviD.
I can't really upload the file as I only have ISDN and no flatrate.. if
you really need it, tell me and I will find a way to get it on your ftp.
"BluesBrothers (XviD 1.0rc3-cvs)_1.mkv" is the file which does not work
and "indy_1.mkv" is the file which "works" - sound however is distorted
and it sounds as if it was encoded with a very low bitrate - artifacts,
hiss and things like that. When I playback the original audio file which
is muxed in the MKV file using mpg123 it sounds completely correct. I
don't get any error messages or warnings or something like that. I will
convert the MKV file to an AVI and see if the sound is still distorted.
However I don't think, that it's the fault of the Matroska Splitter..
Some information about my system, the files, a gdb backtrace and some
other things see below. If you need anything else, just mail me or the
list. :)
