 I work on vaapi support for xine using ffmpeg as decoder.
 While working in my xine stuff i discovered that since quite a while
 decoding of some h264 live material on dvb-s2 was broken with vaapi in
 ffmpeg. The affected material was showing artefacts in the decoded
 picture.
 After some research i discovered following commit for vpdau :

 http://git.videolan.org/?p=ffmpeg.git;a=commit;h=a4ab70f92e4d8705434a2fee42a2b69a8bfa6bb1

 based on that commit i made similar changes to vaapi_h264.c which are in
 the attached patch. This patch is fixing the artefacts.
