[QTvcp.QTVCP.WIDGETS.CAMVIEW_WIDGET][ERROR]  Video capture error: VideoCapture() takes at most 1 argument (2 given) (camview_widget.py:290)

The cam works in vlc (and used to work great in qtDragon).
This is my production machine, using the buildbot version (updated today).

The linux_info file doesn't give any pertinent info.
Can you post the output from he terminal.
On a quick look I can't see an error in the file.
Maybe you could post the camview.py file too?

  Maybe there is something strange going on.... See the screenshot where the checkmarks are gone.

Yesterday I purged the install of LinuxCNC and did a fresh apt install linuxcnc-uspace on this production machine.
Debian 10.12
LinuxCNC LINUXCNC - 2.9.0-pre0-6533-g54bc57f73

Yes it is, so check for a space or a . or whatever that might be seen as the second argument on line 290.
