Updated CentOS 7 the other day. Updated zoom last night. Ancient (15 yr
old) USB camera, Logitech QuickCam Express.
If I run LD_PRELOAD=/usr/lib64/libv4l/v4l2convert.so cheese, I get video.
Zoom, with or without the LD_PRELOAD - no video. I've tried stracing zoom,
and created a file /etc/ld.so.preload, with the contents of
/usr/lib64/libv4l/v4l2convert.so, and in strace, I see it loading it, but
still no video.
I assume you're using the Zoom Linux client since you updated Zoom.
Thinking out loud .. I wonder what would happen if you:
Booted a CentOS 7.6 kernel keeping all else the same
Booted from a variety of CentOS / Fedora Live CD images to see what
kernels do / don't work if it's even kernel related
Try using Zoom via Chrome which can do pretty much everything natively
without Zoom extension
Try using Zoom via Chrome with Zoom extension
Try using Zoom via Firefox with Zoom extension (Zoom with Firefox without
Zoom extension is very limited)
Hope this helps.
