Crash when opening a WMV file

[Pierre Rudloff]

There is a WMV file I am trying to play but VLC crashes when I open it :

[Pierre Rudloff (rudloff)]

Hum, looks like the file is DRM protected...

[Bryce Harrington (bryce)]

For crashes it's required to provide a full backtrace. If apport isn't collecting it automatically you may need to gather it manually using gdb. Be sure to install debug versions of all dependencies to get the necessary symbols.

Sometimes it helps to have an example file that causes the crash, although in this case if its drm protected you may not be legally allowed to redistribute it.

[Rémi Denis-Courmont (rdenis)]

This is probably a bug in libavformat, though it cannot be confirmed with neither a sample nor a stacktrace.

[Bryce Harrington (bryce)]

Thanks Pierre, however that backtrace still lacks the libav symbols. You'll need to install them like:

apt-get install libav-dbg

Then regenerate the backtrace.

[Aditya Avinash (adityaavinash)]

There is a new vlc version available. Try installing it. The bug may be fixed in the latest release.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same issue when running vlc 2.2 and 2.1.3 and totem. my gstreamer version is

[Chris H (harsesus)]

Sorry, typo, my gstreamer1.0-libav is version 1.2.3-1. The problem does not occur with mplayer. Multiple WMV were used to test. All WMV tested produced a core dump in both VLC and Totem.

I get the exact same backtrace, when trying to play apple lossless files (all of them):

I confirm this is not a VLC bug, but a libav one.

[Sebastian Ramacher (s-ramacher)]

If this is still an issue with the latest libav version, please follow https://libav.org/bugreports.html and report the issue upstream.
