Logitech QuickCam 4000 pro

[dwhile]

I am having problems getting ZM to work with this camera.

/var/log gives an error when it tries to set the camera up it seems to be failing on the whiteness parameter - it gives error - invalid parameter.

Anyone any ideas?

Have you tried switching off STRICT_VIDEO_CONFIG in the Options?

Phil,

Yes - I tried that - the daemon continues to run but there are still errors.

Here's what I get with the option on:
Nov 12 19:46:55 unix zmc-d0[8225]: INF [P:15]
Nov 12 19:46:55 unix zmc-d0[8225]: INF [D:24]

Nov 12 19:46:55 unix zmc-d0[8225]: ERR [Failed to set picture attributes: Invalid argument]

and the daemon stops.

If I turn that option off I get:

Does this help?

[tech_fixer]

Seems like ZM is not able to access the shared memory segment where it stores the camera images for processing.

Are you using RedHat 9 by any chance?

Certainly am! Is there a solution??

[dwhile]

Ok I'm getting further!

I have upped the shared memory limit in the kernel and now it gets further - it initialises the camera but I still get errors:

Nov 14 15:05:43 unix zmc-d0[3368]: INF [Loaded monitor 2(Camera1), 1 zones]

[dwhile]

Whey hey!!!

Got it working now!

Need to set the Capture palette as YUV420P to get it to work.

Now I just need to figure out how to get pwcx loaded to get a higher frame rate.
