I was sucessfully using Zoneminder on a home server setup on Ubuntu 9.04.
I recently upgraded my system including a new motherboard and CPU so decided to do a fresh install and upgraded to Ubuntu 9.10.
I have now completed three fresh installs and followed a number o guides on here trying both memory map setups and the initial memory setup where you have to calculate your shmmax and shmall.
Every time the install runs fine but I am left with a situation where my camera image is 'rolling' and has so many lines over it that you can't make out what is happening.
I have increased the debug to 5 and viewed as many logs as I can find but can't see the fault. I have even changed the slot that the capture card is sat in but to no avail.
Ironically, I remember having a similar problem some months back and have even posted here when I managed to solve it but for the life of me I can't remember what i did!
Has any one out there had a similar problem and solved it or is there any one who can think of a solution.
My last resort would be to replace the capture card, but I am reluctant to fork out for a new one at the moment, when I am sure that it is not the problem!
'rolling' image / feed (SOLVED - sort of)

Thanks for replying and sorry it has taken me so long to come back.
In the mean time I have done a fresh install of Ubuntu and ZM and am still having the same problem.
As far as your suggestions, the settings are as follows:
V4L_MULTI_BUFFER - I have tried this both on and off but with no change.
CAPTURES_PER_FRAME - It was at 1 and I have tried it at 2 and 3 but still with no luck.
This is really starting to do my head in! When I have it working, ZM is such a great bit of software but when I have prolems with the settings, it drives me mad![/code]

Well I have managed to resolve the problem.
I have had to set the device format to PAL Nc. No idea why as with the old setup, PAL worked as standard and I have not changed either the camera or the capture card. Must be something to do with the way that Ubuntu 9.10 differs from 8.04??
Any way, I now have two 640 x 480 feeds but only in grey. Colour seems to break it but as long as I have a picture thats the main thing. Ill do some more digging on the colour before posting again!
