[CentOS] Zoom....

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....
