152	152	After choosing a video file, the program starts using the video input in “real time”; since things are not really real-time, the controller does not work too well. (Simulating time properly is not fundamentally a problem but something we didn’t finish implementing.) This means you can mostly ignore the debug-printouts about ticks happening. What you can do is test the image processing / ball detection. This works better than on the Pi, because we are providing controls for pausing or changing the playback speed.
