Method Details

tick

public void tick()

initialize

public void initialize(SurfaceTextureHelper surfaceTextureHelper,
 android.content.Context applicationContext,
 CapturerObserver capturerObserver)

Description copied from interface: VideoCapturer

This function is used to initialize the camera thread, the android application context, and the capture observer. It will be called only once and before any startCapture() request. The camera thread is guaranteed to be valid until dispose() is called. If the VideoCapturer wants to deliver texture frames, it should do this by rendering on the SurfaceTexture in surfaceTextureHelper, register itself as a listener, and forward the frames to CapturerObserver.onFrameCaptured(). The caller still has ownership of surfaceTextureHelper and is responsible for making sure surfaceTextureHelper.dispose() is called. This also means that the caller can reuse the SurfaceTextureHelper to initialize a new VideoCapturer once the previous VideoCapturer has been disposed.

Specified by:

initialize in interface VideoCapturer

startCapture

public void startCapture(int width,
 int height,
 int framerate)

Description copied from interface: VideoCapturer

Start capturing frames in a format that is as close as possible to width x height and framerate.

Specified by:

startCapture in interface VideoCapturer

stopCapture

public void stopCapture()
                 throws InterruptedException

Description copied from interface: VideoCapturer

Stop capturing. This function should block until capture is actually stopped.

Specified by:

stopCapture in interface VideoCapturer

Throws:

InterruptedException

changeCaptureFormat

public void changeCaptureFormat(int width,
 int height,
 int framerate)

Specified by:

changeCaptureFormat in interface VideoCapturer

dispose

public void dispose()

Description copied from interface: VideoCapturer

Perform any final cleanup here. No more capturing will be done after this call.

Specified by:

dispose in interface VideoCapturer

isScreencast

public boolean isScreencast()

Specified by:

isScreencast in interface VideoCapturer

Returns:

true if-and-only-if this is a screen capturer.
