Heavily distorted video feed from USB camera, please help

Post by 81bones »

I have been trying to get ZoneMinder set up on my system for a few days now, and I'm having an issue with the images from my camera that I just can't figure out. I have ZoneMinder v1.25.0 installed on a Mandriva 2010.2 system (kernel 2.6.33.7-desktop-2mnb). I was able to compile it and install it without any errors or issues, and I can access the web interface and set up a monitor.

I wanted to use my Microsoft VX-6000 USB webcam with ZoneMinder. Yes, I know it's a Microsoft camera, and yes, I know there are often problems getting them to work with Linux. However, the camera works just fine. I can use VLC Player and xawtv with the camera and I get a great picture. I can also use the lightweight webcam_server program to view the camera over the internet, and that works great as well. So the camera works with V4L2.

Unfortunately, the picture I get with ZoneMinder is just a jagged jumble of colored blocks. If I move my hand in front of the camera the blocks will shift, so I *think* I really am getting a feed from the camera; there's just something really wrong with the settings. I've tweaked as many ZM settings as I could find and still no change. I've included some examples using a Capture Palette of "GREY" and a Capture Palette of "YUV420" below.

I have no idea what's wrong. I've included some output from my messages log if it will help. I've also included a screenshot of my monitor settings in case it helps. I've noticed there are a few other people in the forums that seem to have this problem and no one has helped them out yet (http://www.zoneminder.com/forums/viewto ... 29&t=18839, http://www.zoneminder.com/forums/viewto ... 29&t=19142) -- so if anyone has any ideas, this may help a bunch of people.
