That bring us closer to the issue I have mention earlier. One would
need to have a look at the GstBuffer produced by vaapidecode, and check
 if there is a GstVideoMeta being set (even though shmsrc/sink does not
support that). If that is the case, it means we need to add a buffer
copy in vaapidecode for that specific case. It will kill the
performance of course, but provide correct output.
