GlShaderProgram.OutputListener (ExoPlayer library)

Enclosing interface:

GlShaderProgram
```
public static interface GlShaderProgram.OutputListener
```
Listener for output-related video frame processing events.
This listener can be called from any thread.

Method Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default void`	`onCurrentOutputStreamEnded()`	Called when the `GlShaderProgram` will not produce further output frames belonging to the current output stream.
`default void`	`onOutputFrameAvailable(GlTextureInfo outputTexture, long presentationTimeUs)`	Called when the `GlShaderProgram` has produced an output frame.

- Method Detail
  - onOutputFrameAvailable
```
default void onOutputFrameAvailable(GlTextureInfo outputTexture,
                                    long presentationTimeUs)
```
    Called when the GlShaderProgram has produced an output frame.
    After the listener's owner has processed the output frame, it must call GlShaderProgram.releaseOutputFrame(GlTextureInfo). The output frame should be released as soon as possible, as there is no guarantee that the GlShaderProgram will produce further output frames before this output frame is released.
    
    Parameters:
    
    outputTexture - A GlTextureInfo describing the texture containing the output frame.
    
    presentationTimeUs - The presentation timestamp of the output frame, in microseconds.
  - onCurrentOutputStreamEnded
```
default void onCurrentOutputStreamEnded()
```
    Called when the GlShaderProgram will not produce further output frames belonging to the current output stream. May be called multiple times for one output stream.
