from Christian König
The problem is neither the driver nor the application, but rather the design of VA-API. The hardware supports some high profile features (like CABAC), but unfortunately not all of them (like B-frames or MBAFF). Now the profile selects what the decoder needs to be able to do to handle a certain video, but doesn't tells you anything about the encoder except for selecting the encoding of the headers. We should support the encoding of the headers, so if an application selects high profile it actually gets better compression because of CABAC support. But if the application also tries to use B-frames it will get an invalid stream. Additional to that we currently have a firmware problem which corrupts all streams != baseline. Could be that you are running into that one. Boyuang is already investigating it and you could try to downgrade your firmware version to test that.
