Problems setting up my webcams

henfri · Post by **henfri** » Sun May 22, 2011 10:24 am

Hello,

first of all I'd like to thank you for this interesting software.
Then I'd like to introduce myself:
We will start building our house soon, and with zoneminder I want to regularly take photos, loading them up to some webspace and later creating a timelapse of it. For this purpose, I want to use 1-2 webcams attached to it.

I have two webcams attached to my zoneminder, which is running on Debian on a Dockstar (Armel).
Below, you find the data of the webcams.

The problem I have is, that I get no output opening the monitors, see the attachment.

Could you please help me, to figure out, what settings I need for these cameras?

Thanks a lot. I've already spent a lot of time, trying around

Greetings,
Hendrik

You shoudl probably read this post and include some of the output from the log files otherwise nobody can really do anything other than guess.

Hi Phil,

thanks for your reply.
The first log (var/log/messages) shows only:

I am using ZoneMinder 1.24.2-8 on Debian squeeze (armel). (packet zoneminder_1.24.2-8_armel.deb)

Unfortunately, the FAQs show only entries for monitors with timestamp. But I don't even have the timestamp (see Screenshot above).

Greetings,
Hendrik

There are a few other logs to check, see http://www.zoneminder.com/wiki/index.ph ... e_Shooting but also it may be that it would be worth running in debug mode and capturing a debug log.

henfri · Post by **henfri** » Sun May 22, 2011 8:27 pm

Hello Phil,

There are three scopes of debug available. Leaving this option blank means that all components will use extra debug (not recommended). Setting this option to '_<component>', e.g. _zmc, will limit extra debug to that component only. Setting this option to '_<component>_<identity>', e.g. '_zmc_m1' will limit extra debug to that instance of the component only. This is ordinarily what you probably want to do.

Can you hint me, what component I should limit the extra debug to?

Besides this: Do you think from the screenshot and information about my camera above, that my settings are correct?

Regards,
Hendrik

Post by **zoneminder** » Sun May 22, 2011 8:57 pm

If you only have the two monitors and they are both causing trouble then just specifying 'zmc' will create a file for each zmc process, suffixed by pid. Otherwise the syntax is zmc_ddevvideo0 (avoiding '/' etc). I would suggest using level 5 to start with,

henfri · Post by **henfri** » Mon May 23, 2011 7:48 pm

Hello,

I have used these settings:
EXTRA_DEBUG checked
EXTRA_DEBUG_TARGET zmc or zmc_ddevvideo0
EXTRA_DEBUG_LEVEL 5
EXTRA_DEBUG_LOG /tmp/zm_debug.log+

I have saved these settings.

The result is not, what I expected:

Code: Select all

ls /tmp/z*
/tmp/zmaudit.log  /tmp/zmdc.log  /tmp/zmdc.sock  /tmp/zmfilter.log  /tmp/zmpkg.log  /tmp/zmwatch.log

/tmp/zmswap-m3:

Do you have a hint?

Regards,
Hendrik

Post by **zoneminder** » Mon May 23, 2011 7:54 pm

That should be enough, but I would do a full ZM restart if you haven't already. Failing that we will have to run it from the command line and see what you get.

Do

Code: Select all

export ZM_DBG_PRINT=1
export ZM_DBG_LEVEL=5
/path/to/zmc -d /dev/video0

in a shell and see what that squirts out.

Hi,

Try using the V4L2 API instead, it has much better support for USB video devices.

Also try with a smaller image size (to start with) for the second one or read this if you want to do a proper adjustment.
