Help with checkerboard error effect
Posted: Tue Mar 23, 2010 3:50 pm
Hello all:
First, thanks for this wonderful software, it works great!.
But I'm having some problems on my setup, I can't get it working correctly.
It happens that my images randomly (and very often) change to a checkerboard effect. This wrecks everything, and the motion detection gets confused.
See what I'm talking about:
As soon as I change some property on v4l, it fixes the error. I.e. if I run the command: v4lctl -c /dev/video0 bright 126 the image gets normal.
My Setup:
Intel(R) Pentium(R) 4 CPU 2.80GHz and 1GB RAM
lspci
So I have 3 video inputs.
Zoneminder logs usually gets lost signal of the camera (could be, they are cheap and they have a long cable run), but only on 2 out of 3 video inputs (video0 and video2). /dev/video1 doesn't have any ZM error and stills appears the checker effect:
dmesg shows an error on each capture card, but it seems a common OpenSuse error related to ACPI on ioremap.c:
Any thoughts???
Thanks in advance
