MPlayer interrupted by signal 6 in module: decode_video
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.

Reproduce steps:
----------------
1. xinit &
2. mplayer -nosound -fps 30 -vo vaapi -va vaapi bitstreams/sony-ct2.bits
