Method Details

onFrameCaptured

default void onFrameCaptured(VideoFrame frame,
 VideoProcessor.FrameAdaptationParameters parameters)

This is a chance to access an unadapted frame. The default implementation applies the adaptation and forwards the frame to CapturerObserver.onFrameCaptured(VideoFrame).

setSink

void setSink(@Nullable
 VideoSink sink)

Set the sink that receives the output from this processor. Null can be passed in to unregister a sink.

applyFrameAdaptationParameters

@Nullable
static VideoFrame applyFrameAdaptationParameters(VideoFrame frame,
 VideoProcessor.FrameAdaptationParameters parameters)

Applies the frame adaptation parameters to a frame. Returns null if the frame is meant to be dropped. Returns a new frame. The caller is responsible for releasing the returned frame.
