All Implemented Interfaces:

PlayerMessage.Target, Renderer, RendererCapabilities, MediaClock
```
public class MediaCodecAudioRenderer
extends MediaCodecRenderer
implements MediaClock
```
Decodes and renders audio using MediaCodec and an AudioSink.
This renderer accepts the following messages sent via ExoPlayer#createMessage(Target) on the playback thread:
- Message with type C.MSG_SET_VOLUME to set the volume. The message payload should be a Float with 0 being silence and 1 being unity gain.
- Message with type C.MSG_SET_AUDIO_ATTRIBUTES to set the audio attributes. The message payload should be an AudioAttributes instance that will configure the underlying audio track.

  - onAudioSessionId
```
protected void onAudioSessionId(int audioSessionId)
```
    Called when the audio session id becomes known. The default implementation is a no-op.

                        throws ExoPlaybackException
```
    Description copied from class: BaseRenderer
    
    Called when the position is reset. This occurs when the renderer is enabled after BaseRenderer.onStreamChanged(Format[], long) has been called, and also when a position discontinuity is encountered.

    Description copied from interface: Renderer
    
    Whether the renderer is ready for the ExoPlayer instance to transition to Player.STATE_ENDED. The player will make this transition as soon as true is returned by all of its Renderers.
    This method may be called when the renderer is in the following states: Renderer.STATE_ENABLED, Renderer.STATE_STARTED.
    
    Specified by:
    
    isEnded in interface Renderer
    
    Overrides:

    If the renderer is in the Renderer.STATE_STARTED state then returning true indicates that the renderer has everything that it needs to continue playback. Returning false indicates that the player should pause until the renderer is ready.
    If the renderer is in the Renderer.STATE_ENABLED state then returning true indicates that the renderer is ready for playback to be started. Returning false indicates that it is not.
    This method may be called when the renderer is in the following states: Renderer.STATE_ENABLED, Renderer.STATE_STARTED.
    
    Specified by:

    Called immediately before an input buffer is queued into the codec.
    The default implementation is a no-op.
    
    Overrides:
    
    onQueueInputBuffer in class MediaCodecRenderer
    
    Parameters:
    
    buffer - The buffer to be queued.
  - processOutputBuffer

```
    Description copied from class: MediaCodecRenderer
    
    Processes an output media buffer.
    When a new ByteBuffer is passed to this method its position and limit delineate the data to be processed. The return value indicates whether the buffer was processed in full. If true is returned then the next call to this method will receive a new buffer to be processed. If false is returned then the same buffer will be passed to the next call. An implementation of this method is free to modify the buffer and can assume that the buffer will not be externally modified between successive calls. Hence an implementation can, for example, modify the buffer's position to keep track of how much of the data it has processed.
    Note that the first call to this method following a call to MediaCodecRenderer.onPositionReset(long, boolean) will always receive a new ByteBuffer to be processed.
    
    Specified by:
    
    processOutputBuffer in class MediaCodecRenderer
    
    Parameters:
    
    positionUs - The current media time in microseconds, measured at the start of the current iteration of the rendering loop.
    
    elapsedRealtimeUs - SystemClock.elapsedRealtime() in microseconds, measured at the start of the current iteration of the rendering loop.
    
    codec - The MediaCodec instance.
    
    buffer - The output buffer to process.
    
    bufferIndex - The index of the output buffer.
    
    bufferFlags - The flags attached to the output buffer.
    
    bufferPresentationTimeUs - The presentation time of the output buffer in microseconds.
    
    shouldSkip - Whether the buffer should be skipped (i.e. not rendered).
    
    Returns:
    
    Whether the output buffer was fully processed (e.g. rendered or skipped).
    
    Throws:
    
    ExoPlaybackException - If an error occurs processing the output buffer.
  - renderToEndOfStream
```
protected void renderToEndOfStream()
                            throws ExoPlaybackException
```
    Description copied from class: MediaCodecRenderer
    
    Incrementally renders any remaining output.
    The default implementation is a no-op.
    
    Overrides:
    
    renderToEndOfStream in class MediaCodecRenderer
    
    Throws:
    
    ExoPlaybackException - Thrown if an error occurs rendering remaining output.
  - handleMessage
```
public void handleMessage(int messageType,
                          java.lang.Object message)
                   throws ExoPlaybackException
```
    Description copied from interface: PlayerMessage.Target
    
    Handles a message delivered to the target.
    
    Specified by:
    
    handleMessage in interface PlayerMessage.Target
    
    Overrides:
    
    handleMessage in class BaseRenderer
    
    Parameters:
    
    messageType - The message type.
    
    message - The message payload.
    
    Throws:
    
    ExoPlaybackException - If an error occurred whilst handling the message. Should only be thrown by targets that handle messages on the playback thread.
