Kodak DVC-325 can't grab image

arosboro · Post by **arosboro** » Sat Dec 10, 2005 7:31 am

I have a Kodak DVC-325 but I can't seem to get a jpeg or other appropriate image to appear from the source in zoneminder. It works fine with gqcam and I've read someone else in the forum has their kodak working.

I was wondering if anyone else could give me some tips. It's the final problem to overcome before I have a fully working setup.

Here's my tail of /var/log/messages:

Thankyou.

ERR [Failed to set picture attributes: Invalid argument]

Usually is a result of an incorrect image size or color is set in zm.

I'll ask but I have just been dispatched out to work so I may not be able to respond for a couple days.

What are your settings in zm?

Try to start with some thing common place like 320x240 and try different color pallets.

Corey

happens when I run zmc -d /dev/vide0 at console

I don't think this is a PAL camera ... I bought it in the us and I remember reading somewhere that it's output is neither pal or ntsc, so I've been playing around with those attributes. It works in gqcam and to a degree in xawtv, but it's hard testing because I'm too lazy to run X and plug in a monitor so instead I use X-Win32 remotely.

If you bought it in the US then most likely it is NTSC, I has to be one or the other else I don't think it would work.
Is it a color or monochrome camera?
Have you tried changing the color pallate to RGB24 ?

Corey

Some how rebooting got my picture working. Maybe the module needed reloaded ... I have it set with NTSC but it works the same with PAL. RGB24 and 320x240 are working. I think grey and 640x480 don't work. 640x480 seems to have errors finding enough memory to store the images. I guess the system only has about 300+ MB ram.

Everything is funcitoning in modect mode w/ jpegs. The only weird thing is that at first I had a black image and I had to set the brightness to 65024 or something like that. Now I have picture but when I adjust hue color or contrast to anything above 0 they go back to 0. Any ideas what may be causing that?

Thanks for your help

Darn it I meant to mention that but I guess I got side tracked somewhere and didn't in my last post. Sorry about that. You should always at least restart zm when you make any camera changes.
