I actually just registered here to comment the first time after lurking for years ;) I had the displeasure to upgrade from a broken g3 flex to a g5 flex, and then finding out they cut out the rtsp stream functionality for unknown (probably business) reasons. I dont plan to buy a protect appliance, and frigate should still handle my nvr stuff, so this comment thread comes really handy right now. Is there any possibility for you to publish this proxy to github or similar?
