System: Ubuntu 18.04
Tested with Zed2 camera using OpenCV's cv::VideoCapture

When launching StereoCameraVideo, the hard drive is filling fast until there is no more space:

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            7.7G     0  7.7G   0% /dev
tmpfs           1.6G   11M  1.6G   1% /run
/dev/nvme0n1p7  288G  288G     0 100% /
tmpfs           7.7G  172K  7.7G   1% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           7.7G     0  7.7G   0% /sys/fs/cgroup
...

The problem can be fixed following this post by deleting /var/log/uvcdynctrl-udev.log and setting uvcdynctrl debug flag to 0: https://askubuntu.com/a/196332

On my computer the log file increased to 45 GB to fill the hard drive:

$ ls -l /var/log
