You have to try this again, I cannot make sense out of your message. What do you mean with: "The buffer remove and buffer done of output queue is separated into two works" I suppose this: the value of owned_by_drv_count isn't zero when output queue stream off before flush decode. should be: therefore the value of `owned_by_drv_count` isn't zero while flushing the decoder in the STREAMOFF(OUTPUT queue) IOCTL. right? >Changing the flush decode from capture to output when stream off to >make sure all the output queue buffers are set to done list. I'd change this section to: Flushing the decoder during STREAMOFF(OUTPUT) instead of during STREAMOFF(CAPTURE) makes sure that all buffers on the OUTPUT queue are set done. The rest looks fine.

The buffer remove and buffer done of output queue is separated into two works, the value of owned_by_drv_count isn't zero when output queue stream off before flush decode. Changing the flush decode from capture to output when stream off to make sure all the output queue buffers are set to done list.
