 // MediaCodecLoop is based on Android's MediaCodec API.
 // The MediaCodec API is required to play encrypted (as in EME) content on
 // Android. It is also a way to employ hardware-accelerated decoding.
 // One MediaCodecLoop instance owns a single MediaCodec(Bridge) instance, and
 // drives it to perform decoding in conjunction with a MediaCodecLoop::Client.
 // The Client provides the input data and consumes the output data.  A typical
 // example is AndroidVideoDecodeAccelerator.
