How can I stream my desktop to node for TensorFlow proccessing?

I want to stream my main computer monitor over to node-red so it can process that stream live using TensorFlow, and I heard that you can stream webcams so I've set up an OBS webcam too so I can downscale it for faster processing. Though I've gotten stuck on actually capturing it, and I don't know where to start on streaming it back so I can see it. Is there a node that can help? I know about the HTTP streams but I don't know how to set it up, will I have to overwrite the node-red connection because of the port? I can even do that type of stream on OBS.

How are you going to stream the video from the monitor ?
