Hi, are there new infos / tips on this error?

I tried the ubuntu live cd with preinstalled zm and I see the same behavior with it.

Today I downloaded newest ffmpeg and zoneminder from svn. I tried with the configure option "--enable-mmap=yes/no"

--enable-mmap=yes:

Code: Select all

Got unexpected memory map file size 2305524, expected 18433204

--enable-mmap=no:

Code: Select all

I compiled vlc from git and my cam works perfect with v4l2.
With a fresh compiled zoneminder I still get a grey or green jerky video.

I was able to make a video from the camera stream using zoneminder. This video was created while using the palette RGB24 and V4L2.if I select YUV422P I get a green video.
I discovered this in my zmdc.log:

Hi,

I see more and more programms, which ran into the problem I got with zoneminder. Only Cheese (which has no options) displays the video.

I tried very much combinations of ffmpeg & zonemonder, but I can't figure out my problem. I tried even a fresh install, but nothing has changed.

It seems that the video palette is not set, no matter which setting I use.
