Glitchy videos while recording with reolink cameras via rtsp / no live-streaming, only recording

[RG_M-2002]

Dear Community,

I urgently need help with a problem. For some time now, strange picture errors and artefacts have been occurring during video recordings using OBS. Unfortunately, the same problem also occurs sporadically with the VLC mediaplayer when I retrieve the signal from the poe cameras.
Unfortunately, I am neither a streaming expert nor an IT specialist and cannot find the cause. However, there is no way around OBS at the moment as I am using the "advanced scene switcher".
I am currently accessing the signals from 4 cameras (Reolink RLC811-A model). The stream is not going out. I only use OBS for recording as I need a flexible solution for my purposes.
I have been looking for a solution for some time. The approach with (FFmpeg options: rtsp_transport=tcp rtsp_flags=prefer_tcp) has unfortunately not had the desired effect.

An error occurred on 10 July at 16:44, the log is attached to this post.
On 11 July at around 15:25 the error occurred again.

Enclosed you will find the logs and the errors, as well as the specifications of my computer.
I hope you can help me?

Specs:
Windows 11
Core i7-12700
16 GB DDR5 - 4800 MHz (2 x 8 GB)
M.2 512 GB SSD
GeForce RTX 3070 / 8 GB / GDDR6

I also had this issue with my C210. chatgpt suggested adding th following parameter, which solved my issue:

fflags=+genpts

Currently I use those parameters for my C210s behind NAT.

rtsp_transport=tcp buffer_size=20000000 fflags=nobuffer probesize=5000000 analyzeduration=10000000 fflags=+genpts
