Example #1

File: RealSense.cpp Project: areslp/HAL

  uvc_error_t RealSenseDriver::getFrame(uvc_stream_handle_t *streamh, uvc_frame_t **frame)
  {
    uvc_error_t err;
    err = uvc_stream_get_frame(streamh, frame, -1); //use the latest acquired frame
    if(err != UVC_SUCCESS)
      {
	uvc_perror(err, "uvc_get_frame");
      }
    return err;
  }
