All Implemented Interfaces:

PlayerMessage.Target, Renderer, RendererCapabilities
```
public class MediaCodecVideoRenderer
extends MediaCodecRenderer
```
Decodes and renders video using MediaCodec.
This renderer accepts the following messages sent via ExoPlayer.createMessage(Target) on the playback thread:
- Message with type Renderer.MSG_SET_SURFACE to set the output surface. The message payload should be the target Surface, or null.
- Message with type Renderer.MSG_SET_SCALING_MODE to set the video scaling mode. The message payload should be one of the integer scaling modes in C.VideoScalingMode. Note that the scaling mode only applies if the Surface targeted by this renderer is owned by a SurfaceView.
- Message with type Renderer.MSG_SET_VIDEO_FRAME_METADATA_LISTENER to set a listener for metadata associated with frames being rendered. The message payload should be the VideoFrameMetadataListener, or null.

```
    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.

    bufferIndex - The index of the output buffer.
    
    bufferFlags - The flags attached to the output buffer.
    
    sampleCount - The number of samples extracted from the sample queue in the buffer. This allows handling multiple samples as a batch for efficiency.
