Summary:
-------------------
The following bug info reproduced both using mplayer and gstreamer to decode mpeg2 files.
But mpeg2 clips displays normally when using mplayer or gstreamer:
 mplayer -nosound -fps 30 -vo vaapi -va vaapi /root/media_tools/decoder/bitstreams/tcela-7-slices.bits

Command line:
-------------------
LD_PRELOAD=/root/media_tools/decoder/i965_drv_video_hook_op.so mplayer -nosound -fps 30 -vo vaapi -va vaapi /root/media_tools/decoder/bitstreams/tcela-7-slices.bits

gst-launch-1.0 filesrc location=/root/media_tools/decoder/bitstreams/tcela-7-slices.bits '!' mpegvideoparse '!' vaapidecode '!' vaapisink sync=false

MPlayer interrupted by signal 6 in module: flip_page
- 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.
