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?
