Hi all, i have been using a philips webcam (PCVC680K vesta pro) for two
years now and never had any problems with it using the pwc module, but
this changed with SUSE 10.0.
I can't get any picture from the device.

var/log/messages show no errors:
Dec 18 21:17:06 SUSE10 kernel: usb 4-1: new full speed USB device using uhci_hcd and address 25
Dec 18 21:17:06 SUSE10 kernel: pwc Philips PCVC680K (Vesta Pro) USB webcam detected.
Dec 18 21:17:07 SUSE10 kernel: pwc Registered as /dev/video0.

When i try to use the device with xawtv i get:
chris(a)SUSE10:~> xawtv -device /dev/video0
This is xawtv-3.94, running on Linux/i686 (2.6.13-15.7-smp)
X Error of failed request: XF86DGANoDirectVideoMode
Major opcode of failed request: 137 (XFree86-DGA)
Minor opcode of failed request: 1 (XF86DGAGetVideoLL)
Serial number of failed request: 65
Current serial number in output stream: 65

I've been searching for the error given by xawtv with google but i can't
find anything relevant, or anything i can read since most of the results
from google were not in english or dutch.

Now when webcams are finaly getting supported by some instant messengers
like amsn and kopete, my webcam stops working :-(
I'm always this lucky :-/

Can anyone help?

Chris Maaskant.

Ok i googled a little more and found that dga (whatever that is) is not
supported anymore by the latest nvidia driver 1.0-8174 so i loaded
1.0-7676 and the dga problems are gone.

Still no picture though, now i get:
This is xawtv-3.94, running on Linux/i686 (2.6.13-15.7-smp)
/dev/video0 [v4l]: no overlay support
v4l-conf had some trouble, trying to continue anyway
ioctl: VIDIOCMCAPTURE(frame=0;height=96;width=128;format=7): Ongeldig argument
ioctl: VIDIOCMCAPTURE(frame=0;height=96;width=128;format=5): Ongeldig argument
ioctl: VIDIOCMCAPTURE(frame=0;height=96;width=128;format=4): Ongeldig argument
ioctl: VIDIOCMCAPTURE(frame=0;height=96;width=128;format=1): Ongeldig argument
ioctl: VIDIOCMCAPTURE(frame=0;height=96;width=128;format=13): Ongeldig
argument

where "ongeldig" means invalid.

So now i'm googleing for getting overlay support..

Don't hessitate to help me in the meantime :-)

Greetings Chris,
Sounds like you may have upgraded to SuSE 10? You may need to install
a newer driver for your kernel. Take a look at www.saillard.org. Look
in the Linux > Phillips Web cam driver section. I too use the
2.6.13-15.7-smp kernel and found the pwc-10.0.7a.tar.bz2 better for
my kernel than the pwc-10.0.9-rc1, but I'm running a Logitech QC Pro
3000. The source modules seem to work better than the rpm's, again my
experience. For help in compiling the module see
http://www.novell.com/coolsolutions/feature/16340.html.
Good luck!
Regards,
Solor^

I'm wondering if trying to force /dev/video0 causes a problem?

I'm not currently using a webcam, but when I did I used kdetv and started
it with no options. On the menu 'video' you could select the cam.

I compiled the pwc-10.0.9-rc1 module and installed it and everything
worked as it used to do, except i now have to use the nodga flag with
xawtv, because the latest nvidia driver doesn't support dga.
I don't even know what dga is or does, so i don't care.

Thanks Solar^ for your time and help,

Chris Maaskant
