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 :;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.
