Hi all,

As ZoneMinder seems to be a great piece of free and Open Source software, I'm very intersting for using it in order to survey my shop.

Here is my configuration:
- EEEbox + Xubuntu 9.04
- Two D-Link DCS 910 (they work with software named motion)
- ZoneMinder v1.23.3 installed thanks to Synaptic package manager

I've set up following settings in /etc/sysctl.conf file:
- kernel.shmall=134217728
- kernel.shmmax=134217728
(and reboot).

Here is the configuration of one of my webcams:

Code: Select all

-GENERAL
--NAME: CAM-CAISSE
-- Source Type: Remote
-- Function: Monitor
-- Enabled: checked
-- Max FPS: 15.00
-- Reference Image Blend: 7

-SOURCE
-- Remote Host Name: 192.168.1.20 (authentication is disabled)
-- Remote Host Port: 80
-- Remote Host Path: /VIDEO.CGI?
-- Remote Image Colours: 24bits
-- Capture Width: 640
-- Capture Height: 480
-- Preserver Aspect Ration: not checked
-- Orientation: Normal

All other settings are set up to default values.

Here an extract of the logs:

I see no error in the log but when I try to visualize camera video output I only see a black screen!! I've tried with IE, Firefox and Opera... same problem!

Any advise would be very appreciated. Thanks

Marcus.

EDIT: Could a moderator move this thread in the right forum please ?

Hi again,

I've decided to try ZoneMinder version 1.24.2 from sources. I've removed ZoneMinder package thanks to Synaptic and successfully installed ZoneMinder v1.24.2 from sources.

My webcams are well detected, as a prove here an extact of the TCP stream captured with Wireshark:

[........very long raw data]

I've set up them in Modect mode. Events are well generated and I can extract them as jpeg but all video extract fail saying Video generation failed.

How can I fiw this problem ? What should I check ? What am I doing wrong ? Thanks in avdance for you help.

Marcus.

Hi one more time,

I've found why I could not see video camera output: that was a CGI directive missing in the virtualhost set up in Apache configuration. I discovered it by checking error.log file of Apache.

Here the configuration I use:

Code: Select all

ServerName cam-recoder
<VirtualHost>
   ServerAdmin webmaster@localhost
   DocumentRoot /var/www/zm
   <Directory>
      Options FollowSymLinks
      AllowOverride None
   </Directory>
   <Directory>
      php_flag register_globals off
      Options Indexes FollowSymLinks
      <IfModule>
         DirectoryIndex index.php
      </IfModule>
      Options Indexes FollowSymLinks MultiViews
      AllowOverride None
      Order allow,deny
      allow from all
   </Directory>
   ScriptAlias /cgi-bin/ /var/www/cgi-bin/
   <Directory>
      AllowOverride None
      Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
      Order allow,deny
      Allow from all
   </Directory>
   ErrorLog /var/log/apache2/error.log
   # Possible values include: debug, info, notice, warn, error, crit,
   # alert, emerg.
   LogLevel warn
   CustomLog /var/log/apache2/access.log combined
</VirtualHost>

Now I can see my to webcam streams

Note that I use JPEG mode. For unknown reason (to me

) MPEG mode doesn't work.

Last problem: video export generation.

is ffmpeg compiled by you or is it a distro package

Posted: **Sat Aug 08, 2009 9:13 pm**

Was this ever fixed? I am having the same problem and was hoping you discovered the problem.

You can use mjpeg with remote host path /MJPEG.CGI, if you uncheck ZM_NETCAM_REGEXPS under Options/Network

Some where it seems that your defined output container is not properly defined. check and make sure your options in ZoneMinder are set correctly in FFMPEG_FORMATS and that you are selecting a format. Otherwise you will need to trace down why it's putting in 0x0000.

I get this same error no matter what output format I select for video generation. I am running 1.24.2 and FFMPEG_FORMATS is set to the installation default: mpg mpeg wmv asf avi* mov swf 3gp**

I have tried ffmpeg SVN-r19480 and r20006. Am I missing something?

I posted my full ffmpeg.log file in this thread:

anybody fix this problem ?

Posted: **Sat Feb 05, 2011 8:09 am**

Hi,

All those suffering from ffmpeg failing to generate a video, please try ffmpeg 0.6 or newer, although this might be break compatibility with old versions of ZM. If that happens, use ZM from SVN.
