I am just getting started with Zoneminder so thought I'd give it a try with my old V4l1 webcam, which is a Labtec (with no other markings on). I have got it working through Skype by doing the LD_PRELOAD method:
LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v41compat.so skype
However, I can't get it working in Zoneminder. I have tried adding the command below to the zmdc.pl script, but that hasn't worked - I just get a blank screen:
$ENV{LD_PRELOAD} = '/usr/lib/i386-linux-gnu/libv4l/v41compat.so';
I have also tried increasing the shared memory as someone suggested elsewhere, and played around with the Zoneminder source settings, but nothing has worked yet.
I am currently running Lubuntu 12.10, and Zoneminder was installed via apptitude.
Can anyone help?
