Yeah sorry, should have said you need to convert the RTSP first, but there are multiple ways of doing that, github also has multiple projects for it for example. What I use is a bit different, i have a CCTV recorder with the RTSP url that is being recorded (on motion), but since the stream disconnects after 5 minutes it currently can’t record continious. So on movement i use the "stream card) which triggers the EUFY servers to start the stream, and i already record that stream, so i can record it now (with a delay).
Main thing here is that for this to work you need to remove the timestamp and token from the RTSP stream that you are recording, but it needs those 2 for creating the stream, so the “stream card” makes the EUFY servers create the stream, and then you can record/watch it without the date/token (they change every time).
And yeah, it’s a very nasty workaround…but it works
