Updated CentOS 7 the other day. Updated zoom last night. Ancient (15

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
It didn't work with 6.x. I rebuilt the beginning of April to CentOS 7.
Didn't work, until I got rid of the default gspca_spca561, and used the
gspca_spca508. Updated the beginning of this week, and didn't work until
I went back to gspca_spca561.
Works 100% of the time with cheese, when I add that preload.
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
I was really, really trying to avoid installing chrome.
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)
Been trying to join a test meeting in firefox, and it opens a new tab,
and demands that I use the app.
Hope this helps.
Thanks for trying.... I may have to try chrome (really didn't want
google scanning what I do to sell it.
