just wanted to share a recent success of mine. I've been running octoprint for over a year with a cheap RTSP IP camera and I could only ever get a screenshot to work on the live stream portion of octoprint.
after stumbling across this thread on reddit, https://www.reddit.com/r/octoprint/comments/eoz25z/octoprint_and_wyze_cam/
user Eroji has made a solution that works perfectly for me with my noname RTSP IP camera!!
I have had zero issues with this now, live stream is now working on the octoprint page which is very nice. I could access a screenshot previously, or the live stream via VLC or otherwise. now it just works.... and I didn't need to run software on any external device to do it. all on the Pi
