crash when trying to watch matroska encoded videofiles

[Stephan Rügamer]

With dappers version (I only tested dappers version) watching matroska encoded videofiles (*.mkv) is not possible.

It crashes with:

VLC media player 0.8.4 Janus
*** glibc detected *** free(): invalid pointer: 0x084eac88 ***
Aborted

I'll attach a backtrace just now

I get the same error in the latest Dapper, with a very similar backtrace.

[Reinhard Tartler (siretart)]

could you please provide a sample video for testing?

[Daniel Robitaille (robitaille)]

The one I tried was this one:
http://www.bunkus.org/videotools/mkvtoolnix/samples/vsshort-aac.mkv

That directory on that web site contains a very sample mkv files

[Daniel T Chen (crimsun)]

I've temporarily placed test packages for dapper/i386 at http://sh.nu/~crimsun/vlc/ ; please verify that they fix your mkv crashes.

[Daniel Robitaille (robitaille)]

The crash on that mkv file still occured after I upgraded to your test packages. The only 3 packages installed on my laptop that had upgrade available in your test directory were:

vlc_0.8.4.debian-1ubuntu6_i386.deb
vlc-plugin-alsa_0.8.4.debian-1ubuntu6_i386.deb
wxvlc_0.8.4.debian-1ubuntu6_i386.deb

[Daniel T Chen (crimsun)]

Thanks for testing. Is the crash with mkvs reproducible with the debs here [0]?

[0] http://nightlies.videolan.org/build/breezy-i386/vlc/

[Daniel Robitaille (robitaille)]

They don't install in Dapper:
dpkg: dependency problems prevent configuration of vlc:
 vlc depends on libcdio3; however:
  Package libcdio3 is not installed.
 vlc depends on libdbus-1-1 (>= 0.36.2); however:
  Package libdbus-1-1 is not installed.
 vlc depends on libiso9660-3; however:
  Package libiso9660-3 is not installed.
 vlc depends on libsysfs1; however:
  Package libsysfs1 is not installed.

If you force the install, then it complain at runtime about:
vlc: error while loading shared libraries: libdbus-1.so.1: cannot open shared object file: No such file or directory

Interestingly, they don't install in Breezy either: it needs libgcrypt11 > 1.2.2 while Breezy's version is 1.2.1-3

[Terry Callan (tcallan)]

I can confirm that the nightlies version is uninstallable under dapper. However, adding the vlc nightlies repository for breezy:
deb http://nightlies.videolan.org/build/breezy-i386 /
allows installation. (It contains libgcrypt11_1.2.2)
Under breezy this updade removes the problem.

[Daniel T Chen (crimsun)]

Can those of you using current Dapper please test the debs at http://nightlies.videolan.org/build/dapper-i386/vlc/0.8.5-test2/ against a mkv file? I've built and tested up through 0.8.5-test4, and they all crash in the mkv demuxer, leading me to believe that one of the libraries we use is outdated and needs an UVFe req.

[Daniel Robitaille (robitaille)]

I installed that 0.8.5-test2 version in Dapper (Flight 7), and it still crashes on that vsshort-aac.mkv file (url in a previous comment). The error is:

VLC media player 0.8.5-test2 Janus
*** glibc detected *** free(): invalid pointer: 0x085f2be8 ***
Aborted
