Thanks for reporting.

But you need to see bug #778942, #734093.
There's a reason that jpeg caps is missing in vaapidecode.

Why don't you use vaapijpegdec as the pipeline you show, by the way?

Hello

sorry for the report, you are right 
the patch was from a older testing with vaapidecoderbin

all works fine with vaapijpegdec
