Problem with ZM and Logitech Quickcam 9000 Pro& Advice?

force · Post by **force** » Wed Jan 26, 2011 1:20 pm

Hello Folks,

i run a Ubuntu 10.10 System and ZoneMinder 1.24.2.

I installed Ubuntu on a old PC (P4 with ~2Ghz i think^^), and installed ZoneMinder via the Synaptic Pakets.

I already can accsess ZM via network, but the Logitech wont show up any pictures. The Cam works with Cheese and the suggestied programm from the wiki (xierTV or something like this?)

I did everything they said in http://www.zoneminder.com/wiki/index.ph ... m_Pro_9000

BUT

it wont work.

something strange, when i run
zmu -d /dev/video0 --verbose -V1 --query
i get this:

Code: Select all

Video Device: /dev/video0
Video Capabilities
  Name: UVC Camera (046d:0990)
  Type: 1
    Can capture
  Video Channels: 1
  Audio Channels: 0

  Contrast: 8224
  Whiteness: 0
Channel 0 Attributes
  Name: Camera 1
  Channel: 0
  Flags: 0
  Type: 2 - Camera
  Format: 0 - PAL

(I noticed that the picture attributes are kinda messed up?)

Current settings are

General:
Source Type: Local
Function: Monitor
Enabeld: (marked)

Source:
device path: /dev/video0
capure method: video for linux vers. 2
device channel: 0
device format: pal
capture palette: yuyv
capt. width: 960
capture height: 720

last bot not least: I want to monitor a small office. 24/7 because some drunk ppl tried to break in about 2 days ago. (its a funeral-director's office - dont know what they expected in here)

i want to set up another (IP-)Camera, had in Mind to set up a SHARP IP-E-134-100b

Is that easier because i only have to access the camera-ip or even harder to set up that damn logitec webcam? :/

im not a pro at linux, but i know some basics and i am willing to learn. but im a bit afraid they will try to break in again this weekend

thanks for your help in advance

Can you enable debugging and post what your logs show?

im not a genius, but i think there is something wrong with the shared momory

cat /proc/sys/kernel/shmall

Code: Select all

and

cat /proc/sys/kernel/shmmax

Code: Select all

33554432

i did

Code: Select all

echo 33554432 >/proc/sys/kernel/shmall
echo 33554432 >/proc/sys/kernel/shmmax

but nothing happend after restarting zm

google brought me to another thread and a quadrozillion other hits, told me to
chmod 666 /dev/mem

chmod: Beim Setzen der Zugriffsrechte fÃ¼r â€ž/dev/memâ€œ: Die Operation ist nicht erlaubt

(operation not allowed)

:/

What kind of specs does your system have? Also, I'm not sure, but I think your system has to be restarted for the kernel memory parameters to take effect, or you need to run sysctl/sysconfig (something like that). Also make sure /dev/videox has full permissions.

FWIW, try starting 'small' with ZM... ie: just monitor mode, cut your buffer sizes down very low, and make sure you also use the correct parameters for your camera. For example, my cams will only work at 640x480. If I specify anything else, I will get errors. The shared memory errors can mean any number of things, and it's best to rule out whatever you can before chasing it down.

Also make sure /dev/videox has full permissions.

Can't shmget is almost always not enough shared memory set, the explanation and fix is here: http://www.zoneminder.com/wiki/index.ph ... solutions.

01/27/11 09:12:35.270497 zmwatch[8315].ERR [Can't get shared memory id '7a6d0002', 2: No such file or directory]

The "can't get shared memory id xxxxxxxxx" usually only means there's nothing there to get. Fix your shared memory settings and you'll be back on the right track

"edit": if your current values are 134217728 then increase 150% to 201326592, if you still get the can't shmget error increase to 200%

I use the same webcam
using:
$ cat /proc/sys/kernel/shmall
134217728
$ cat /proc/sys/kernel/shmmax
