hit brick wall conecting USB Quickcam Pro 4000

[daves]

Hi all,

I have installed ZoneMinder on xubuntu Gutsy, it has a zoneminder package 1.22.3-7 . My problem is with my USB Quickcam Pro 4000 webcam - after
a lot of tinkering I still cant get it to display an image in ZoneMinder.

I checked compatibility, the camera works under ekiga - but I dont know what that app uses under the hood so I looked up
linuxquestions.org HCL and it says the the 4000 works great with v4l

Next I checked modules ...

dave@dave-desktop:~$ lsmod | grep pwc
pwc 86272 0
compat_ioctl32 2304 1 pwc
videodev 29312 1 pwc
usbcore 137864 9 snd_usb_audio,snd_usb_lib,usblp,pwc,usb_storage,libusual,ehci_hcd,uhci_hcd
dave@dave-desktop:~$

so pwc is loaded ... ok so far ...................................................................

dave@dave-desktop:~$ xawtv -hwscan

Googleing I found that -nodga might be the answer ......................................

xawtv -nodga -c /dev/video
a window flashes on the screen, followed by xfce completely resetting itself opps !

OK so getting the info from xawtv ..........................................................

Mmmm ... shared memory not valid ??.................................


So I fed the above data into the ZoneMinder config ... zip images.
Im stuck !!! Any suggestions on where to go from here

Cheers

WOW just had a breakthrough , installed zonemonitor on KDE, (I thought - try KDM instead of GDM)

dave@dave-desktop:~$ xawtv -nodga -c /dev/video
This is xawtv-3.95.dfsg.1, running on Linux/i686 (2.6.22-9-generic)

dave@dave-desktop:~$

so I linked /dev/video0 to /dev/video ... then ...

root@dave-desktop:/dev# xawtv -nodga -device /dev/video0

And I can see my picys in xawtv :)

Still zip in zoneminder though !
