All Superinterfaces:

CapturerObserver

Modifier and Type	Method	Description
`static VideoFrame`	`applyFrameAdaptationParameters(VideoFrame frame, VideoProcessor.FrameAdaptationParameters parameters)`	Applies the frame adaptation parameters to a frame.

- 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.
