Interface VideoProcessor

All Superinterfaces:

CapturerObserver

public interface VideoProcessor
extends CapturerObserver

Lightweight abstraction for an object that can receive video frames, process them, and pass them on to another object. This object is also allowed to observe capturer start/stop.

Method Detail

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.
