Black Screen on Reolink Cameras

[mgranger]

I have four cameras right now and I am having trouble getting two setup in Zoneminder. The two I am having trouble setting up are Reolink (one is 412 and other is a 422) I am setting them up using RTSP and I am able to get them running but after a few minutes I lose the image and the whole screen will go black. I have both cameras set up so the FPS is 2 within the camera itself. I don't really understand why this happens? Any advice on what is wrong?

Here is some of the error log:

I found that "remote" works better than "ffmpeg" long term. Also, confirm with VLC for your image sizes.

Sometimes I will lose an image and just going to the setup screen and saving without changing anything will correct the image. I think the stream gets out of sync and the decoder loses it's place.

I am using remote because I found the same thing to be true. I do go into the setup screen without saving and reset to correct the image but within a few minutes it happens again. It just happens to often to be reliable

Reolink claims that their products are ONVIF compatible. See: https://reolink.com/3rd-party-compatibility/

Therefore you should be able to use any of several ONVIF utilities, including the Zoneminder built in, to get the camera paramaters to get to the stream. Yes, confirm the stream string with VLC and also take note of the video resolution. Ffmpeg is likely your best bet with newer cameras. Many cameras can output multiple video streams such as mpeg, jpg and h.264. With modern hi def cameras h.264 with a fram rate of 5 fps and a key frame interval of 2 to 10 seconds should be good. As always get it working with a low video resolution and work upward as you learn the impact on your server.
