 I built "multimedia/vlc" (1.1.13) and it was able to play all the
 media files that caused mplayer to crash.  vlc segfaults on exit though
 it's qt4-related, rather than av-codec-related.  (I should note that when
 mplayer crashes, it doesn't leave a core file behind).
 
 Then I built "multimedia/vlc2" (2.0.3 in pkgsrc-2012Q3) and it dies with
 a segfault as follows:
 
 Core was generated by `vlc'.
 Program terminated with signal 11, Segmentation fault.

 Backtrace stopped: previous frame inner to this frame (corrupt stack?)
 
 I will try building with PKG_OPTIONS.vlc2+=debug to see if there's more
 information to be had.
