I can see the video from my camera when I:

xawtv -c /dev/video0

But I get a broken image, where there should be video, when I set it up in zoneminder.

Where do I start? No errors in any of the relevant logs.

If there are no errors then try switching zms<->nph-zms.

Got frustrated, so did the ol' reboot.

Getting useful logged errors now, along with this at startup:

Code: Select all

# /etc/init.d/zoneminder start
 * Starting zoneminder ...                                                                [ !! ]
#

I'm guessing the capture daemons aren't working for some reason?

Wasn't sure what user needed to be added to the 'video' group, so I just made the device world readable.

Code: Select all

# ls /dev
lrwxrwxrwx  1 root root         10 Feb  3 17:05 video0 -> v4l/video0

Code: Select all

# ls /dev/l4v
crw-rw-r-x  1 root video 81, 0 Feb  3 17:05 video0

Here are some excerpts from the shiny new error logs it finally started making:

That seems to be about it. Sorry if this has been covered before, I really don't know what to search for. Camera works perfectly fine in kopete and xawtv. No, I don't try to run them simultaneously...

[Moved to correct topic]
Is there any errors showing in messages?
What Distro are you using?

Revelation: user is apache.

Added apache to video group.

(shouldn't have mattered since permissions are 777 on both /dev/video0 and /dev/v4l/video0)

'Stills' view works! But 'stream' just shows me the icon for 'waiting for image to arrive' framed out by the proper 320x240 dimension that the image will be if it ever arrives. And it never does. Note, this never becomes a 'broken image' icon.

If I switch to stills, then back to stream, the stream view shows me the last image captured in stills, but it never updates or changes.

Seems to record in mocord (events appear and cpu usage goes up a lot during events), But since the playback for events is streaming method, I can't see it. Don't think it's browser related, as the same thing happens in Firefox on both Winblows and Linux/KDE, Konqueror in Linux/KDE, and IE in Winblows.

Perfect 30fps output in xawtv, kopete, etc....

So now try changing zms<-->nph-zms (apache runs cgi that start with nph so that it will not parse the headers). This whould be the only situation where you might not see any errors in the apahe or other ogs.

I tried it upon your first suggestion, with no effect. I have changed it back and forth 4 times, restarting the zoneminder daemons after each change. No effect.

What browser are you using?
The stream will ot work in IE without cambozola.jar installed.
If you check the properties of the frame the image should be in, what does it show for a path?
Have you checked the apache error log to make sure nothing funny going on there?

If stills view works, check that (Options/paths/ZM_PATH_ZMS) the path to zm cgibinaries directory be correct. You switched between zms and nph-zms, BUT are they really where zm is looking for them ?
