Black Picture after installation of 1.24.2

Hello,

I updated my zoneminder installation to 1.24.2 today. I installed it from source on Ubuntu 9.04 using the guide in the wiki.

Everything worked out fine but now I can’t get a picture on any of my cameras anymore. They just stay black. All of the sources (/dev/video*) in ZM also show up as red for some reason.

I’ve tried "chmod 777 /dev/video*" for debugging purposes but that changes nothing. Everything worked fine with the older version (I believe it was 1.23.3 or so).

Here are the logs:

Why does it fail to set the video format?

It is set to PAL and RGB24 which is also what the old installation was set to and worked just fine.

try to run on the terminal as root:

zmfix

or have a look at the permissions for the /dev/videoxxx by doing

ls -l /dev/video*

hope it helps

What are the settings you have defined in ZM for that monitor, and are they within the bounds of the output you have above from zmu?

I fixed the problem by trying different Device Format/Capture Palette options for the cameras.

The working settings in 1.23.x were PAL/RGB24 but in 1.24.2 I had to set PAL B/BGR24 to make the cameras work. Everything is back to normal now. :)

This error is a good indicator that it didn't agree with one of the setting you had. Glad you got it sorted.
