Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

͏    Probably driver issue.
͏    "The current MFX implementation is not supported, try next MFX implementation."

͏    Maybe current FFmpeg expected certain minimum driver version:
͏    That no more applicable to the specific hardware.
