Process and decode all OUTPUT buffers queued by the client before the VIDIOC_DECODER_CMD() was issued and mark the last buffer with V4L2_BUF_FLAG_LAST flag. Decoder is stopped after processing the last buffer. Resume the decoder when one of below are issued by client: - V4L2_DEC_CMD_START - pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the CAPTURE queue - pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the OUTPUT queue Add the handling to resume decoding when client issues V4L2_DEC_CMD_START to resume decoding after source change is detected.
