Support V4L stateless video decoder API by NVIDIA Tegra decoder driver. Tested using GStreamer [1] and libvdpau-tegra [2]. [1] https://github.com/grate-driver/gstreamer/commit/b8509bdbb69b534e61419ea1798f32f9ad2f3597 [2] https://github.com/grate-driver/libvdpau-tegra/commit/f822e95911e5e0c39f8ba19f843ddc1e0138d5ce Changelog: 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.
