VideoFrameProcessor.Listener

Kotlin |Java

interface VideoFrameProcessor.Listener

Listener for asynchronous frame processing events.

All listener methods must be called from the Executor passed in at creation.

Summary

Public functions
`Unit`	`onEnded()` Called after the `VideoFrameProcessor` has rendered its final output frame.
`Unit`	`onError(exception: VideoFrameProcessingException!)` Called when an exception occurs during asynchronous video frame processing.
`Unit`	`onInputStreamRegistered( @VideoFrameProcessor.InputType inputType: Int, format: Format!, effects: (Mutable)List<Effect!>! )` Called when the `VideoFrameProcessor` finishes `registering an input stream`.
`Unit`	`onOutputFrameAvailableForRendering( presentationTimeUs: Long, isRedrawnFrame: Boolean )` Called when an output frame with the given `presentationTimeUs` becomes available for rendering.
`Unit`	`onOutputFrameRateChanged(frameRate: Float)` Called when the output frame rate changes.
`Unit`	`onOutputSizeChanged(width: Int, height: Int)` Called when the output size changes.

fun onEnded(): Unit

Called after the VideoFrameProcessor has rendered its final output frame.

fun onError(exception: VideoFrameProcessingException!): Unit

Called when an exception occurs during asynchronous video frame processing.

If this is called, the calling VideoFrameProcessor must immediately be released.

fun onInputStreamRegistered(
    @VideoFrameProcessor.InputType inputType: Int,
    format: Format!,
    effects: (Mutable)List<Effect!>!
): Unit

The VideoFrameProcessor is now ready to accept new input frames, bitmaps or textures.

Parameters
`@VideoFrameProcessor.InputType inputType: Int`	The `InputType` of the new input stream.
`format: Format!`	The `Format` of the new input stream.
`effects: (Mutable)List<Effect!>!`	The list of `effects` to apply to the new input stream.

fun onOutputFrameAvailableForRendering(
    presentationTimeUs: Long,
    isRedrawnFrame: Boolean
): Unit

Called when an output frame with the given presentationTimeUs becomes available for rendering.

Parameters
`presentationTimeUs: Long`	The presentation time of the frame, in microseconds.
`isRedrawnFrame: Boolean`	Whether the frame is a frame that is `redrawn`, redrawn frames are rendered directly thus `renderOutputFrame` must not be called on such frames.

fun onOutputFrameRateChanged(frameRate: Float): Unit

Called when the output frame rate changes.

Parameters
`frameRate: Float`	The output frame rate in frames per second, or `NO_VALUE` if unknown.

fun onOutputSizeChanged(width: Int, height: Int): Unit

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 setOutputSurfaceInfo.
