mkvtoolnix broken?

Hi all!

I recently converted some TV recordings to Mpeg4 Video and Vorbis Audio and wanted to mux the resulting streams together in Matroska containers. Almost everything works fine except for the resulting Matroska files having incorrect information about the duration of the Media - mkvinfo, mplayer and vlc tell me that the duration is 0 seconds. The files play fine but I can't seek in them with vlc and don't have this nice seeking bar in mplayer and this is really annoying me. Since I tried mkvmerge with nearly every video/audio stream I've got on my hd and every result's got the same problem I'm almost sure that this is not a problem with the source media.

I already filed a bugreport for mkvtoolnix on its webpage and the developer of it is almost sure that this is not the fault of his applications. Someone else had the same problem and finally found out that the problem was libebml and libmatroska being compiled with gcc 3.3 while kvtoolnix (which links to the former libs) was compiled with gcc 4. So all he had to do was to recompile both libraries and mkvtoolnix with the same compiler to get the bug fixed. I tried to do the same but the problem still exists. See http://www.bunkus.org/anthill/query.php?bug=183 and http://www.bunkus.org/anthill/query.php?bug=182.

Now I wanted to ask if anyone else has got the same problem with the Arch packages of libebml, libmatroska and mkvtoolnix or am I the only one having this problem? In case you want to test if it works for you, I put up two sample streams: http://nooms.de/up/short.avi http://nooms.de/up/short.ogg which you can mux with

mkvmerge -o short.mkv short.avi short.ogg

To get the duration of the file in the Matroska header use

mkvinfo short.mkv | grep Duration

Thanks for the reply. Anyone else can confirm this problem? Or, better yet, anyone else has an idea what could cause this?

It's a bug in libebml that got fixed just a few days ago. The fixed version is 0.7.7 (extra still has 0.7.6 though): https://www.bunkus.org/anthill/query.php?bug=183
