 /**
  * Helper class to create and synchronize access to a SurfaceTexture. The caller will get notified
  * of new frames in onTextureFrameAvailable(), and should call returnTextureFrame() when done with
  * the frame. Only one texture frame can be in flight at once, so returnTextureFrame() must be
  * called in order to receive a new frame. Call disconnect() to stop receiveing new frames and
  * release all resources.
  * Note that there is a C++ counter part of this class that optionally can be used. It is used for
  * wrapping texture frames into webrtc::VideoFrames and also handles calling returnTextureFrame()
  * when the webrtc::VideoFrame is no longer used.
