But this prevents CMD_STOP from being used during a dynamic resolution change to mark the last source buffer. Since CMD_STOP is ignored, but doesn’t fail, there is no warning that the command needs to be resent, and CAPTURE will continue to attempt to dequeue buffers waiting, futilely, for one with V4L2_BUF_FLAG_LAST. Fix this problem by carrying out en/decoder commands even if CAPTURE is not streaming.
