FrameProcessor.Listener (ExoPlayer library)

Enclosing interface:

FrameProcessor
```
public static interface FrameProcessor.Listener
```
Listener for asynchronous frame processing events.
All listener methods must be called from the same thread.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`onFrameProcessingEnded()`	Called after the `FrameProcessor` has produced its final output frame.
`void`	`onFrameProcessingError(FrameProcessingException exception)`	Called when an exception occurs during asynchronous frame processing.
`void`	`onOutputFrameAvailable(long presentationTimeUs)`	Called when an output frame with the given `presentationTimeUs` becomes available.
`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 FrameProcessor.setOutputSurfaceInfo(SurfaceInfo).
  - onOutputFrameAvailable
```
void onOutputFrameAvailable(long presentationTimeUs)
```
    Called when an output frame with the given presentationTimeUs becomes available.
    
    Parameters:
    
    presentationTimeUs - The presentation time of the frame, in microseconds.
  - onFrameProcessingError
```
void onFrameProcessingError(FrameProcessingException exception)
```
    Called when an exception occurs during asynchronous frame processing.
    If an error occurred, consuming and producing further frames will not work as expected and the FrameProcessor should be released.
  - onFrameProcessingEnded
```
void onFrameProcessingEnded()
```
    Called after the FrameProcessor has produced its final output frame.
