I Cant get working any camera Debian with Lenny

Post by subnic »

Hi guys,

I've been playing around with ZoneMinder for a while but i can't get working my IP camera, i've been looking and reading the wiki, i've tryed the shared memory trick and every think i found or figured out, but without luck.

This is my system:

Code: Select all

ZoneMinder 1.24.2
Linux Debian Lenny
Vivotek PT32x7 IP Camera
ZoneMinder is working in the system and it looks just well. When i configure the camera using the JPG file mode i can't get any image, the viewer is black.

if i put this address in my browser i can get the camera image just fine:

Code: Select all

http://user:password@<ip>:<port>/cgi-bin/video.jpg
When i start looking for a fix i found about the shared memory and i calculate the value for my system and increase the memory but it is still not working.

this is the te output with the command tail -f /tmp/zm*

You may need to recheck the shared memory settings.

What resolution are we looking at here? The wiki figures work for 640x480 but if you're a megapixel camera then you'll need to at least double them.

Hello and thanks for reply :)

I've been playing with the shared memory, i calculated with the FAQ tutorial the amount of memory i need as follow:

Code: Select all

352*288px * 24bit color * 80 frames buffer * 1.1 (+ 10%) = 29196288 bytes
and then i set it for my session:

Code: Select all

echo 29196288>/proc/sys/kernel/shmall
but the result is same, same logs and it is still not working.

I've tried as well leaving the shared memory as i explained and change the camera configuration to

Code: Select all

100*75px * 8bit color * 40 frames
but ti is still not working, just a black square...

any ideas? do you think it could be usefull to recompile ZM with MMAP or something?

thanks in advanced.

Hi, first of all thanks for the reply :)

My system is a Dual PIII 933Mhz wirh 512Mb RAM running Debian Lenny, i want to use just one IP camera for now (the vivotek) what is 352x288px but i culdn't get it working.

I'm gonna try to recompile it and i'll tell you.

by the way, compiling with nmap is encesary to tweak the shared memory as well?

Thanks!

I've been owrking around the problem, i followed the next steps:

- Uninstall ZoneMinder (everything even the DB)
- Recompile/reinstall Zoneminder with mmap

but i'm still having the same problem, i can't watch my camera. Now the logs are diferent, as:

GENERAL:

Source Type -> Remote
Function -> Monitor
Enabled -> True

SOURCE:

Remote Protocol	-> HTTP
Remote Method	-> regexp
Remote Host Name -> user:pass@local-ip	 
Remote Host Port -> 55444	
Remote Host Path -> /cgi-bin/video.jpg	
Remote Image Colours -> 24 bit	
Capture Width (pixels) -> 352px
Capture Height (pixels)	-> 288px
Preserve Aspect Ratio -> NO	
Orientation -> Normal	
what is for the Remote Method option? what is the diference between simple and regexp?

I don't know what else to try, i will apreciate any help!!

thanks everyone

shmall is the total size of RAM linux is permitted it to use. The value you calculated should go in shmmax. The value you should put in shmall should be something a bit less than the total RAM on the machine.

As KeithB says, you're only doing half the steps for the current session

From the wiki

Code: Select all

echo 134217728 >/proc/sys/kernel/shmall
echo 134217728 >/proc/sys/kernel/shmmax
That should be ample for a up to 640x480 .

Hi Flash_ I have changed the values as follow:

Code: Select all

kernel.shmall = 536870912
kernel.shmmax = 524288000
But it is still not working...

Why i have to change the shared memory settings if i'm ussing mmap now?

I've tried as well, installing ZoneMinder in antoher computer with Ubuntu 10.4 Descktop (AMD 64 4200+, 2GB RAM) but i'm having the same problem, i'm not able to get any frame from the camera...

Is my config settings (se above) right for a camera giving to me a JPG file?

I can do MPEG streaming too but i think this use a propietary protocol from Vivotek...

I keep trying... Thanks for your help.
