Asynchronous mode of operation is the key feature. Asynchronous filtering MediaCodec for both decoder and encoder is used in asynchronous mode. This makes processing much faster. At the same time it makes the implementation more difficult.For a pleasant Android user experience it is vital for applications to actively provide feedback. When downloading images and data from the web, delays are expected. Developers should implement asynchronous connections and provide active feedback on their progress. Throttling connections is another important technique.In broad terms, a codec processes input data to generate output data. It processes data asynchronously and uses a set of input and output buffers. At a simplistic level, you request (or receive) an empty input buffer, fill it up with data and send it to the codec for processing.はじめに.
