Comment (by cehoyos):

 Replying to [ticket:3226 michalsrb]:
 > Summary: Playing a video in vlc crashes with SEGFAULT in libavcodec.

 I played your sample on Opensuse 12.3 with vlc ~ten times and I do not
 experience a crash, What cpu does your system use?

 > Crash happens **at random time** (each time different).

 This would normally indicate a hardware problem. (Did you run memtest86
 recently?)
 Please test the following command line:
 {{{$ vlc --ffmpeg-threads=1 sample-file.avi}}}
 If you can not reproduce the problem, try heating your cpu at the same
 time, for example with the following command:
 {{{ $ ffmpeg -f lavfi -i smptehdbars -vcodec png -f null -}}}

 > I am not sure how (if possible) to reproduce it with ffmpeg command
 only.

 You can try the following:
 {{{$ ffmpeg -i sample-file.avi -f null -}}}
