I'm on Fedora 10 with a Logitech QuickCam E3500.
Previously, I've been running with the stock 1.23, but had to use mjpg_streamer via an http: ref. in ZM for the cam as ZM didn't support V4L v2 which the camera apparently needs (hope I'm not talking tosh here!).
Seeing 1.24 was out, and having read that it should be able to support V4L v2, I compiled my own 1.24.2 RPM from the Fedora rawhide baseline and have installed it to give it a run.
However (!), the camera's not working in ZM, and I was wondering what the errors I'm seeing might indicate. Needless to say, the camera itself is OK: it was working with mjpg_streamer, and also Skype and cheese.
The errors I'm seeing are:
zmu -d /dev/webcam/e3500-1 -q -v
Error, failed to query crop /dev/webcam/e3500-1: Invalid argument
and
zmwatch[20376].ERR [Can't get shared memory id '7a6d0001', 1: No such file or directory]
I think I'm more concerned about the latter initially. Several searches have turned up other refs. to this error, but most a while ago and none seem relevant. I think I recall seeing something in the changelog about 1.24 doing something different in this area; maybe I've inadvertently compiled it up wrong?
I have tried upping the 'shmall' kernel setting, to no avail (it's already quite high on my box of other reasons anyway).
