Rtsp insted of usb camera


Have just started with Jetson and I have not much experience since before. I have started with the first course Getting Started with AI on Jetson Nano. I have the USB or the csi camera to choose from. But I want to use a network camera insted. I have read o lot in this forum but I cant understand how I should do it. I have so far succeeded to get a picture from a rtsp stream in vlc. Can someone help me where to start?

Best Regards
