Vision Processing Error

Technical Java
#1

Hi, my team is trying to do Vision Processing this year, and we are having some issues. The robot can detect a stationary target from boot, but once the target starts to move around a bit, it throws this error:

ERROR: serve_fc: Too many simultaneous client streams (MjpegServerImpl.cpp:403)

My code is as follows:

@Override
	public void robotInit() {
		Pipeline visionPipeline=new Pipeline();
		visionThread=new Thread(() -> {
			UsbCamera camera=CameraServer.getInstance().startAutomaticCapture();
			CvSink imageSink=CameraServer.getInstance().getVideo();
			CvSource imageSource=CameraServer.getInstance().putVideo("fc", 320,240);
			Mat image = new Mat();;
			Mat image2 = new Mat();
			List<MatOfPoint> contours;
			while (!Thread.interrupted()) {
				// Tell the CvSink to grab a frame from the camera and put it
				// in the source mat.  If there is an error notify the output.
				if (imageSink.grabFrame(image) == 0) {
					// Send the output the error.
					imageSource.notifyError(imageSink.getError());
					// skip the rest of the current iteration
					continue;
				}
			image.copyTo(image2);
			visionPipeline.process(image2);
			contours=visionPipeline.filterContoursOutput();
			Imgproc.drawMarker(image2,new Point( Imgproc.boundingRect(contours.get(0)).x, Imgproc.boundingRect(contours.get(0)).y),new Scalar(0,0,255,255));

			
			
			//Imgproc.drawContours(image2, contours, -1, new Scalar(0,0,255,255));
			imageSource.putFrame(image2);
			}
		});
		visionThread.start();
		

	}

Has anyone had similar issues and been able to fix them?
