removing the fill buffer after the data, processing, processing, after the end of the buffer marked "empty", Go back to the queue for the "producer" to continue populating the data.On the input side, "Client" is the ring buffer "producer", "Mediaocodec module" is "consumer".On the output side, the "Mediaocodec module" is the ring buffer "producer", and "Client" becomes "consumer".This is the core of the principle of work, in fact, not complicated, we calm down, we will soon be able to understan
