After close scrutiny of the VP8 specification, it seems the VP8 stateless API is ready. This series contains a series of clean-ups and improvement: renaming symbols for consistency, documenting things for clarity, and then moves the control to proper V4L2 headers. It must be noted that, unlike parsed H.264, V4L2_PIX_FMT_VP8_FRAME buffers must contain the VP8 frame header. In others words a VP8 parsed frame buffer is: +--------+-----------------------------------------------------+-----+------------+ | tag 3B | extra 7B | header | MB data | DCT size | DCT part 0 | ... | DCT part N | +--------+-----------------------------------------------------+-----+------------+ Hopefully the pixel format documentation is now clear about that. Support in Cedrus and Hantro is available upstream, and Mediatek support is available downstream [1] which uses the API as-is. This was tested with GStreamer v4l2codec [2] element and Fluster [3] conformance test, on a Hantro G1 device.
