 Starting somewhere between ffmpeg-1.1.4 and ffmpeg-1.2 something happend
 with the vaapi code in ffmpeg that's causing crashes when decoding mpeg2.

 I'm not 100% sure if only mpeg2 is affected, and i'm also not sure what
 might be causing this. It Looks like vaapi is not properly initialized, as
 the pic param buffer is missing.

 A possible backtrace looks like this:

 This one is from a vlc git master build. The same happens in XBMC. Both
 using latest master ffmpeg/libavcodec.
