Hi all,
I upgraded my desktop last weekend and decided to try the new
*uvideo*driver from OpenBSD.
When I run |pwcview|, the image is displayed incorrectly: it is
horizontally duplicated and shows interlaced lines.
If I switch back to |webcamd|, the webcam works normally.
I also tested it with *Google Meet*and *Jitsi Meet*in Firefox.
On Google Meet, I receive a warning indicating that my webcam is not
functioning properly.
Has anyone experienced this issue or have any suggestions on how to
troubleshoot it?
My web cam is HD Pro C920 USB
