Hi All,

lsusb finds my camera, and /dev/video0 is created. Because skype did not work with this webcam, I've decided to use
but this complained that the lib does not exist... however lsmod tells me that this module is already loaded and used by uvcvideo and videodev. Because I could not find v4l1compat.so in the entire system I've decided to install it again at different location and point LD_PRELOAD=/usr/local/lib/libv4l/v4l1compat.so to that location. Fail! skype (2.1.x and 2.2.x) still does not see the camera. Any other ideas?

Hi, I see you have no reply and I might not be much help but will try. I had this problem too and at the time I was running Slack 64 bit (using multi lib) and like you tried reinstalling the module but to no avail. You also need to realise there are two possible modules depending on if you are running 32 bit or 64 bit. (google). In the end I must confess I gave up trying to get it to work and this together with some other issues I was having made me reinstall 32 bit. Bit of a sledgehammer to crack a nut but that's what I ended up doing. My advice, make sure you are loading the correct module for your distro.

Thanks for your reply.

Reinstalling is not an option, as I have to many apps/crosstools etc for development on this machine.
I do not think that is a must to run skype with webcam. I'm pritty sure is must be v4l1compat.so lib but where it lies is not as important.
I had similar issue with Ubuntu on different machine and LD_PRELOAD did the trick, but slackware seems to be more resistant

Any other points/ideas?

Any app (other than skype) that would test my webcam?

You should not need the v4l1compat.so library for this web camera. It is a UVC device which should works just fine with V4L2 and skype. I have the 310C and it works just fine without the compatibility library.

Try installing guvcview from slackbuilds.org to make sure your camera is working properly before worrying about the skype configuration.

Wanted to install guvcview, but this required v4l-dvb... Installed v4l-dvb and now uvc module is not loaded and /dev/video0 is missing! I've decided to complete with guvcview, complained about missing portaudio and ffmpeg. Did that went back to guvcview to continue installation process... now libudev.h complains - from what I've found I need to install libudev-dev but there does not seem to be native Slackware package out there.
Any links, source etc?
And why is my video0 now missing?

If you need build scripts and source for those packages check out SlackBuilds.org. Those packages should be there.

As far as /dev/video0 not registering, I have no idea. Most webcam's I've had just work out of box using V4L2 and whatever capture program I'm running at the time.

I don't run your webcam or Slackware. I gave up on Skype though and went with Jitsi

Updated kernel to 2.6.39.4... still nothing, installed v4l but can't see it when lsmod - why?
guvcview fails big time, constantly requires some other packages - gave up after installing other 5 that it depends on.

Installed S13.37 (was going to do that anyway) and Logitech Webcam C510 worked out of the box!

I seem to remember having to preload libv4l2convert.so, with skype, the same webcam and slackware 13.0. I will check in a few hours if you are still interested

Sure I want to be able to run webcam in both distros

FWIW, I checked my old Aspire One + C510, slackware 13.0 + skype 2.1.x and libv4l2convert.so preloaded, it works fine.

However, I remeber having once to wipe out my .Skype dir (warning: it includes personal data which one may want to backup) because otherwise no webcam would be detected. But it occurred only once. Somehow something got corrupted there.

Also, I had problems powering on the netbook with the cam already plugged in (no uvcvideo loaded). But powering on on and *then* plugging it in always worked.
