Hi, folks, 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. Anyone got any clues? Being a free end user, all zoom offers is the knowledge base.... mark ------------------------------------------ Mark, I am runnning Centos 7.8 with a Logitech Brio webcam that move around to use on a multiple of machines that are set up the same way. Cheese worked fine, but Zoom would not work at all. I could not get Zoom to work on these until after I installed 'kamoso'. This ended up being an easy, easy fix for me. Hope it works for you too.
