This is not failing because of shared memory but because it cannot open your video device. It should be able to adjust the permissions to suit but for some reason that is not working. Can you temporarily, as root,

Code: Select all

chmod 777 /dev/video0

and then restart ZM and see if that makes any difference.

ive now got a black box !

camsource still gives an image though.

and when I go console->webcam->settings->brightness changing it to anything results in '0' being rewritten into the box and the image doesnt change
