 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.
