Stuck

[stefs22]

Pi 4 2gb ram.
Reolink 410w and Reolink Duo.
Yes, like this, i try with rtsp and rtmp links.
On both first a couple of seconds i get works, but after a couple of minutes it start to stutter, and stutter more and more until you simply cant watch this.
It happens 2 things:
First and mostly- cam stuttering
Second and rare, cam works good, but timing is wrong, it a bit slower, for examle, if it 12.00, time on cam is 11.50, and like time go, its slower and slower, ali after one hour, timing is 4, 5 minutes back.
Pi is cool, around 60c, cpu is not more that 5percent, i try with low, med, high res, its just stuttering.
I put gpu mem to 128,256, 512, 600, 700, 800, it not want to boot when i put more than 700, so i just now leave on 512.
I do everything i can, i change sd card, try full and lite rom, disable screen saver, low bandwitch on cam for 4x, add swap file up to 4gb, but its the same.

Sorry for my bad english.

Also, i found online some streams of roads in my city that i will want to have to watch.
But, its images that update every 10 or 15 seconds, when i try this to vlc, its play to 10sec and turn off, can this be set?
