Hi,
The 2 libraries that you speak of (libebml and libmatroska) are requirements of mkvtoolnix which creates, alters and inspects mkv files. Thus they are not requirements to actually
play the files.
A current svn release of ffmpeg will play the mkv files and also allow you to identify the different elements in the container. For example:
Code:
andrew@skamandros~/movies/matrix$ ffmpeg -i matrix.mkv
FFmpeg version SVN-r15563, Copyright (c) 2000-2008 Fabrice Bellard,

Input #0, matroska, from 'matrix.mkv':
Duration: 02:11:20.44, start: 0.000000, bitrate: N/A
Stream #0.0(eng): Video: h264, yuv420p, 720x416, 25.00 tb(r)
Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16
Stream #0.2(eng): Audio: aac, 48000 Hz, stereo, s16
Must supply at least one output file
where you will see 3 elements: a video track encoded with h264 and 2 aac audio tracks. A modern version of vlc, the svn mplayer and the svn ffplay should be able to play this type of file. You might run into trouble, as has been suggested, if you are using versions of this software supplied by your distro that have been deliberately crippled.
