Describe the issue/problem and steps to reproduce

Dear Developers,

Recently I experience glitches and jumps often on the recorded footages. I have gigabit network at home, works well. I tested the system with openRTSP as well without problem. The source of motion's RTSP stream are two Tapo C110 cameras (there is a good quality, high speed Sandisk MicroSD inside in one of them); Both in 720p mode. In the past I didn't experience these problems.

The problematic videos(previews):

[Mr-Dave]

This just sounds like PI performance.

[tosiara]

I agree, that looks like a performance issue, check CPU usage. Try to run only one camera with the lowest resolution possible (ex, use sub-stream) and you will notice that the issue will go away.

ARM devices are not capable of decoding 720p RTSP H264 and encoding at the same time

[anonimusz20220712]

This is by Munin, but maybe the frequency(time intervals) is not high enough:

It was never too high :(

[anonimusz20220712]

The load was neither

[tosiara]

you want to say that those graphs are showing Rpi4 running and recording 2x 720p RTSP cameras? please show the graph since the beginning of february

[anonimusz20220712]

This is that day:

[anonimusz20220712]

Tha load wasn't too high:

[tosiara]

Can you reproduce the issue with one camera and upload a full log with -d 9 ?

[anonimusz20220712]

OK, I will check it out!
