#10855: Huge RTSP latency achieved over long time of streaming from specific IP
camera

I've discovered that RTSP video latency can grow over time when using some
specific IP camera.
Command line used with ffplay.exe 6.1.1 on Windows to have low latency:
```
ffplay.exe -y 420 -fflags nobuffer -flags low_delay
rtsp://someuser:somepass@192.168.3.111:554/AVStream1_1
```
I've launched two instances of ffplay for this "problematic" camera on the
left, and two instances with other camera that seems to work fine on the
right, and in the video attached you can see that problematic camera
latency grown more than 10s over weekend.
