Odd "jumps" in frames when streaming form the Reolink client

ole

Hi all.

I'm new in the IP-Cam world.
I've connected two Reolink RLC-520 IP-CAMs.

I've played around with resolution, bitrate and FPS - but I encounter a problem.
When streaming via the Reolink Client (windows) then the frames "jumps". I can see that the time-stamps jumps a lot. I can see that movements are "flickering" of "old" frames being submitted.
Sometimes I also encounter GREEN frames (if that is any help).
I've checked the recordings, and they show exactly the same issue as the live-stream - hence it's the actual stream, which is affected.

Any tips and tricks?
