Hi, I read this email thread regarding 'flush operation'in v4l2 m2m driver framework: http://www.spinics.net/lists/linux-media/msg42944.html To implement a 'flush' operation, I should implement support for 'V4L2_DEC_CMD_STOP' command. Is my understanding correct?/ But my currently just implement 'stream_on/stream_off' function callback, do I need to switch that to V4L2_DEC_CMD_START' command? If not, I find it weird that my driver implemention has support for V4L2_DEC_CMD_STOP not V4L2_DEC_CMD_START (and user need to call stream_on to start, stream_off to stop and V4L2_DEC_CMD_STOP for 'flush' Thank you. -- 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
