Shared memory troubles - Ubuntu 8.04

volto · Post by **volto** » Sat Oct 18, 2008 2:45 am

Hi im on Ubuntu 8.04, zoneminder 1.23.3
Trying to connect to D-Link DCS-5300g network cameras.
I am unable to get any images to show.

It seems I dont have enough shared memory, but...

I have these settings in my /etc/sysctl.conf
kernel.shmall=2097152
kernel.shmmax=40550400

on 704x480x24 I get a broken image
on 320x240x24 I get a black image
on 320x240x8 I get a black image

debug set to 4

With 320x240 I get this in the debug log:

Thanks in advance for any help.

is this on an analog on a Ipcam if so what brand
Because this happen to me on an Axis when i specified the wrong size and it out put a different resolution also if it is anolog the cameras must all have the same resolution set on most cards

Captured image does not match expected size, check

It's a D-Link DCS-5300g

resolution of output image is 704x480x24

Thanks
