hi
i am trying to use a USB webcam with GEM on my IBM laptop with Ubuntu Studio but pd gives me an error
error: failed opening device '/dev/video0'
the same camera runs perfectly on the same laptop under XP and also on my desktop machine with Ubuntu Studio. All using the same patch and same versions of PD and GEM.
The camera is a logitech quickcam communicate STX PD 0.39.3 extended-rc5 Linux r2d2-desktop 2.6.20-16-lowlatency #2 SMP PREEMPT Fri Aug 31 00:58:46 UTC 2007 i686 GNU/Linux
The camera seems to be recognised, if i plug it on i can see the camera's blue light flashing and dmesg gives this :
[27776.980572] ubuntu/media/gspcav1/gspca_core.c: USB SPCA5XX camera found.(ZC3XX)
same message as in the desktop machine.
Comparing the PD output from both machines i can see that after saying
- GEM start rendering
my desktop says :
- v4l::thread starting
but the laptop says:
- error: failed opening device '/dev/video0'
i searched with synaptic for v4l and compared all stuff installed in both machines just in case i was missing some library in the laptop, but it is exactly the same in both...
my bet is that some module is missing, but i dont know which ones might be as i havent mess around with modules very much so far, i am comparing the lsmod from the desktop and laptop at the moment, there are few differences but i dont really know where to start from, any one has any idea?
thanks!

I don't really know Linux, but have you test your configuration (usb
webcam) with pdp object ([pdp_v4l]) ?
I know it's not a good answer, but it could help to know if your
webcam work with your system.
Sorry !

With GEM and [pix_video] you can send the message [driver 0( or
[driver 1( to switch between drivers (e.g: v4l and ieee1394).
I can't test here.

most likely it is a problem with permissions: check whether there is a file /dev/video0, and check which permissions are set. are you in the correct group?

Sorry, i was on the wrong way :)

hi altern
according to this:
http://www.qbik.ch/usb/devices/showdev.php?id=3503
you need a driver called 'dkms-gspca'.
