Support V4L stateless video decoder API by NVIDIA Tegra decoder driver. Tested using GStreamer [1] and libvdpau-tegra [2][8]. [1] https://github.com/grate-driver/gstreamer/commit/b8509bdbb69b534e61419ea1798f32f9ad2f3597 [2] https://github.com/grate-driver/libvdpau-tegra/commit/f822e95911e5e0c39f8ba19f843ddc1e0138d5ce [8] https://github.com/grate-driver/libvdpau-tegra/commit/80db4d02369f2a984ce3173d6bc305f32e9fdb97 Changelog: v5: - Corrected drivers/staging/media/Makefile, where I removed the VI driver instead of VDE. This was reported by the 0-DAY build bot. v4: - Added r-b from Nicolas Dufresne to the "V4L2_H264_DECODE_PARAM_FLAG_P/BFRAME flags" patch. - Added patches to de-stage driver, like was suggested by Hans Verkuil. - Added patch to enable driver in ARM's multi-platform defconfig. v3: - Added new decode_params flags [7] instead of V4L2_BUF_FLAG_*FRAME flags, as was suggested by Nicolas Dufresne. [7] https://github.com/grate-driver/gstreamer/commit/c5cd847f9c26b7669720ae58f9058de2515f51a2 - Added new patch that removes legacy UAPI. v2: - Made V4L2_BUF_FLAG_*FRAME flags mandatory [3] and dropped reading of raw bitstream from the driver code, as was suggested by Nicolas Dufresne. [3] https://github.com/grate-driver/gstreamer/commit/aee292f0f2e84b7654a314dd7e63f916888ffaa5 - Ran v4l2-compliance [4] and fluster [5][6] tests, like was suggested by Nicolas Dufresne. Fixed minor v4l2-compliance errors that were related to a partial initialization of the coded format and were harmless in practice, but made compliance checker unhappy.
