Mjpg-streamer is a good open source project to use as a video server, using the V4l2 interface. We talked about the transplant process earlier, but in certain circumstances the project does not meet our needs, so we need to modify the source code, or directly write a video server. Before you modify the source code or write your own server, we analyze the source codes.
There are three par
