    Nicolas and I have discussed the pixel format, and came up with
    the following proposal.

    Given this format represents H264 parsed slices, without any start code,
    perhpaps we name it as:

    V4L2_PIX_FMT_H264_SLICE_RAW

    Then, we'd also add:

    V4L2_PIX_FMT_H264_SLICE_ANNEX_B

    To represent H264 parsed slices with annex B (3- or 4-byte) start code.
    This one is what the Rockchip VPU driver would expose.

    Ideas?
