Linux linux-xxx 2.6.25.20-0.4-default #1 SMP 2009-06-01 09:57:12 +0200 x86_64 x86_64 x86_64 GNU/Linux
>1 The Webcam has works within ekiga but don’t do it today!
and it is not possible to bring them back working
>2 when i start Audacity as the First program after i have reconfigure the Audio System with alsaconf the Mic works.

Please take a look at the following thread to see if any of the command lines in that thread work with your Dell XPS M1730 web cam.
webcam & microphone command line fun … - openSUSE Forums

They work for me (where annotated) with my Dell Studio 15 laptop.

I can’t remember how openSUSE-11.0 handles the webcam driver for the Dell Laptops. I have openSUSE-11.1 and I believe I have the uvc kernel module …

oldcpu@studio15:~> lsmod | grep uvc
uvcvideo               50928  0
compat_ioctl32          1104  1 uvcvideo
videodev               31236  1 uvcvideo
v4l1_compat            13096  2 uvcvideo,videodev
usbcore               165892  5 uvcvideo,usbhid,ehci_hcd,uhci_hcd

Yep !! uvc. What does “lsmod | grep uvc” give for your laptop?

I note I have luvcview:


oldcpu@studio15:~> rpm -qa | grep uvc
luvcview-20081013-0.pm.4

Do you have that installed? But having typed the above, I am not 100% certain you have same webcam.

“lsusb” gives for my laptop:

Bus 004 Device 003: ID 05ca:18a1 Ricoh Co., Ltd

Whose packaged version of v4l and ffmpeg and libffmpeg have you installed? Packman packaged version? For example, I get:

oldcpu@studio15:~/data/xtreme> rpm -qa | grep v4l
libv4l-0.5.9-10.pm.8
libpt2-plugins-v4l2-2.4.2-2.19
v4l-conf-3.95-179.57

and

oldcpu@studio15:~/data/xtreme> rpm -qa | grep ffmpeg
libffmpeg-devel-0.5-0.pm.3
libffmpeg0-0.5-0.pm.3
gstreamer-0_10-ffmpeg-0.10.7-42.pm.1
ffmpeg-0.5-0.pm.3

That mencoder line works for me on my dell.

If I were you, I would focus my efforts on that v4l2 error. I note your “v4l” applications are different from what I have installed. Could that be the problem?

oldcpu@studio15:~> rpm -qa | grep v4l
libv4l-0.5.9-10.pm.8
libpt2-plugins-v4l2-2.4.2-2.19
v4l-conf-3.95-179.57

Also, google for: " v4l2: ioctl set format failed: Invalid argument " and see if you can discover a solution by such a google search.

I’m currently in Bangkok, with a very slow internet connection. I’ll be back in Europe at week end.
