  • Method Details

    • initialize

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

    • startCapture

      void startCapture(int width, int height, int framerate)
      Start capturing frames in a format that is as close as possible to width x height and framerate.

    • stopCapture

      void stopCapture() throws InterruptedException
      Stop capturing. This function should block until capture is actually stopped.
      Throws:
      InterruptedException

    • changeCaptureFormat

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

    • dispose

      void dispose()
      Perform any final cleanup here. No more capturing will be done after this call.

    • isScreencast

      boolean isScreencast()
      Returns:
      true if-and-only-if this is a screen capturer.
