Are your webcams working? (slackware 13.0)


Hi all,

I earlier posted the same question at slackware.hu but did not get a definitive reply (that is a rather small community in Eastern Europe)

Until slackware 12.1 I used my webcam (Philips SPC 200NC PC Camera) with the gspca driver set. Since 12.2 the webcam is not working anymore. Although the drivers are now integrated into the kernel and recognized by boot (the correct driver is loaded) tha cam is not working.

There seems to be an issue wit v4l and the appications (Skype, Kopete for ex.), attempted to use v4l1compat (from Hans de Goede) as others seemed to have success (on other systems) with that but that did not solve the problem on 12.2 and 13.0.

So my question: are any of your webcams working on a stock 13.0? (and I should throw away/replace my webcam and stop asking stupid questions ;-) or are webcams not anymore supported on Slackware?

this is a very old issue since the 2.6.27 kernel yes they work. but for the old gspca v4l1 cameras you need this package if it is for 12.2 then go to 12.2. the 2.6.27 kernel came out with 12.2.
then when you want to run any program even your web browser that will use your cam with flash you need to start the program or edit the launchers like this.
Quote:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so "YOUR Program"
or
Quote:
LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so "YOUR Program"
Other wise go get a v4l2 cam.
If you have problems let me know. I use the gspca cam with slack 12.2,13, 13-64, current.

v4l

Hi Darkeo,

I tried libv4l (as noted above) compiled by me and the slackbuilds version , both (better said: all of them, as I made some 7-8 tests) ended up with a message somewhat like "...v4l1compat.so can not be preloaded"

"v4l2 cam". OK. I am not aware what that should be.

(What I know so far from reading around is that some applications do not understand v4l2 not the webcams.)

The built-in webcam on my Asus 900HA netbook worked 'out-of-box' on a Slackware 13.0 install... however it uses the uvcvideo driver.

I posted some details here.

My old Webcam live! (VF0050) is working with gspca_main + gspca_zc3xx and libv4l-0.6.1 built from SlackBuild.

My webcam is Logitech Quickcam Messenger 046d:08f0. Although it driver is unofficially supported, it cannot compile against 2.6.30.5. It does not also compile against kernel versions later than 2.6.29.6 unless you apply the patch:
http://www.kuhrti.de/index.php/artic...n-ubuntu-9-04/

Anyway, I am really fed up with having webcam problems any time I upgrade my kernel. I will either switch to an earlier kernel version, i.e. downgrade, or buy a new better supported webcam. Of course unless somebody discovers some solution in the mean time. I would also be thankful to receive some recommendations for webcams innately supported by the Linux kernel.

Regards,
Martin

Been using the same cam since Slackware 10 the problem is the knowledge base and the v4l1 v4l2 32 bit 64 bit. I think as the kernel evolves it is up to us to keep the simple sym links for the libraries alive with documents and this is how we do it.
this web cam issue was solved after the 2.6.27 kernel came out. then when the slackware64 came out we need to ad the libraries for the old cams that use the old v4l1 and slackbuild was there and ready.

Try the windows driver with ndiswrapper.
It worked fine for me with some my integrate camera before or wireless card now.
Best,

Eric.

The problem is that in windows the camera performs pretty bad too. In Linux with the 3-rd party driver I got much better pictures.
