 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

 After some research i discovered following commit for vpdau :


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