Method Detail

setSurfaceTextureHelper

default void setSurfaceTextureHelper(SurfaceTextureHelper surfaceTextureHelper)

getSupportedFormats

List<VideoFormat> getSupportedFormats()

Returns list of all supported video formats this capturer supports.

isScreencast

boolean isScreencast()

Indicates whether the capturer is a screen cast.

Returns:

true if the video capturer is a screencast and false if not.

startCapture

void startCapture(VideoFormat captureFormat,
                  VideoCapturer.Listener capturerListener)

Starts capturing frames at the specified format. Frames should be provided to the given listener upon availability.

Note: This method is not meant to be invoked directly.

Parameters:

captureFormat - the format in which to capture frames.
