[FFmpeg-devel] Matroska demuxer gives presentation order in dts

i just stumbled over some strange behaviour when reading Matroska files,
the reported pts are in expected presentation order (non-monotonous),
but the dts values of the packet are as well!

Beside that the Matroska demuxer reports several issues with that file, like
Ignoring seekhead entry for ID=0x1549a966
Unknown entry 0x73a4 in info header
Unknown track header entry 0x55aa - ignoring
Unknown attachedfile ID 0x46ae

Is there interest in this file? can one just cut 10mb off the start of a
 mkv file and it still is useable? Original is nearly 100mb in size.

I am much more interested in the dts problem though...

Regards, Thorsten
