VideoFrameProcessor.Listener (ExoPlayer library)

Enclosing interface:

VideoFrameProcessor
```
public static interface VideoFrameProcessor.Listener
```
Listener for asynchronous frame processing events.
All listener methods must be called from the Executor passed in at creation.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`onEnded()`	Called after the `VideoFrameProcessor` has rendered its final output frame.
`void`	`onError(VideoFrameProcessingException exception)`	Called when an exception occurs during asynchronous video frame processing.
`void`	`onOutputFrameAvailableForRendering(long presentationTimeUs)`	Called when an output frame with the given `presentationTimeUs` becomes available for rendering.
`void`	`onOutputSizeChanged(int width, int height)`	Called when the output size changes.

- Method Detail
  - onOutputSizeChanged
```
void onOutputSizeChanged(int width,
                         int height)
```
    Called when the output size changes.
    The output size is the frame size in pixels after applying all effects.
    The output size may differ from the size specified using VideoFrameProcessor.setOutputSurfaceInfo(SurfaceInfo).
  - onOutputFrameAvailableForRendering
```
void onOutputFrameAvailableForRendering(long presentationTimeUs)
```
    Called when an output frame with the given presentationTimeUs becomes available for rendering.
    
    Parameters:
    
    presentationTimeUs - The presentation time of the frame, in microseconds.
  - onError
```
void onError(VideoFrameProcessingException exception)
```
    Called when an exception occurs during asynchronous video frame processing.
    If an error occurred, consuming and producing further frames will not work as expected and the VideoFrameProcessor should be released.
  - onEnded
```
void onEnded()
```
    Called after the VideoFrameProcessor has rendered its final output frame.
