    decoder: h264: add support for grayscale encoded clips.
    
    Fix support for grayscale encoded video clips, and possibly others if
    the underlying driver supports the non-YUV 4:2:0 formats. i.e. defer
    the decision that a surface with the desired chroma format is not
    supported to the actual VA driver implementation.
