At the V4L2 codec API session during ELC-E 2014, we agreed that for the decoder draining flow, after a V4L2_DEC_CMD_STOP decoder command was issued, the last decoded buffer should get dequeued with a V4L2_BUF_FLAG_LAST set. After that, poll should immediately return and all following VIDIOC_DQBUF should return -EPIPE until the stream is stopped or decoding continued via V4L2_DEC_CMD_START. (or STREAMOFF/STREAMON). regards Philipp Peter Seiderer (1): [media] videodev2: Add V4L2_BUF_FLAG_LAST Philipp Zabel (1): [media] videobuf2: return -EPIPE from DQBUF after the last buffer drivers/media/v4l2-core/v4l2-mem2mem.c | 10 +++++++++- drivers/media/v4l2-core/videobuf2-core.c | 18 +++++++++++++++++- include/media/videobuf2-core.h | 1 + include/uapi/linux/videodev2.h | 2 ++ 4 files changed, 29 insertions(+), 2 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
