Maybe try installing v4l-dvb or v4l-dvb-development_2.6.37

Guest · 2012-06-05 20:35:30

Yes, thank you a lot Trixar_za for your help,

i can install v4l-dvb-development_2.6.37 and my webcam is recognize

But after i have this message : would you like to test the webcam?

i answer "y" for yes

It install Mplayer

but i have this :

Mplayer interrupted bu signal 6 in module :preinit_libvo

-Mplayer crashed. This shouldn'd happen.

and my webcam don't work in skype

do you have an idea ? what can i do?

I don't really have much experience with webcams and Linux, but maybe try installing xorg-xf86-video-v4l to see if that helps Xorg see the Video4Linux device.

Guest · 2012-06-05 21:34:24

yes i've installed it but how i launch it ? i don't find it in my menu list

Trixar_za · 2012-06-05 22:13:00

Xorg is started automatically. It's what makes Windows and Program GUIs show up. It also controls how your mouse and keyboard interacts with them.

Guest · 2012-06-06 00:43:29

ah ok...

Yes i've installed it , my webcam appears in skype but it don't work.

Anybody has an idea??

we can't use webcam in slitaz???

Guest · 2012-06-06 10:35:21

I'm sure there is a way but i can't find it, do you know others drivers for my webcam? it is recognized by skype as USB webcam 2.0, why it isn't work?

Trixar_za · 2012-06-06 10:40:46

Another wild guess but try installing linux-video and see if that helps. Running [c]tazhw detect-usb[/c] as root might also help.

Guest · 2012-06-06 10:53:50

I've installed linux-video

and it is the same

when i run tazhw detect-usb, my web is recognized,

but i can't test or use it because : when i try to test it : Mplayer crash

and in skype i can chose the webcam but IT DON'T WORK, the screen stay black

Why can i test or use my webcam? in skype or other software

Guest · 2012-06-06 16:12:39

I bought another webcam Logitech C210, and it's worse, when i plug it, all slytaz bug, i have a black screen with code and i can't do anything but shut off my pc manually...

can you help?

Guest · 2012-06-06 17:22:56

Je pense que je vais être obligé de passer à lubuntu, vraiment dommage, mais si je dois revenir sur windows à chaque fois que je veux utiliser skype ou msn, ce n'est pas possible

I think i will have to go to lubuntu, really a shame, but if i have to go back to windows everytime i want use skype or msn, it is'nt possible

gdesilva · 2012-06-07 08:37:41

I have the same issue.

lsusb list that it is a Logitech Quickcam and I can get the microphone working but not video.

Ran fswebcam and I get the following message...

root@GDES:/proc# ls -la /dev/video0

crw-rw-rw- 1 root video 81, 0 Jun 8 01:40 /dev/video0

root@GDES:/proc# fswebcam

i have found the solution : move to another distribution, i've moved to lubuntu, it isn't as light as slitaz but it's ok it's lighter than ubuntu, and i have no problem, all work instantly. I did want a very light distrib, but if drivers don't exist for devices very common like standard webcam (UVC), it serves at nothing. byebye slitaz, with regrets

gdesilva · 2012-06-09 05:49:12

It appears that the pwc driver is broken. A dump of /var/log/messages when the camera was plugged in and when fswebcam app was run is given here - http://pastebin.com/htmNjkE2

Downloaded a Logitech supplied qc-usb-0.6.4 driver from http://sourceforge.net/projects/qce-ga/files/qc-usb/0.6.4/ and tried to compile it but did not have much success.

Any ideas? thanks.

Try this I have resolved on my italian topic http://forum.slitaz.org/topic/slitaz-su-eeepc-900hd#post-9197

pipein · 2012-06-09 07:16:22

@gdesilva

Hopefully gibor's resolution fixes it for you (my Italian is not great).

Just for reference, if you are using Logitech Quickcam 4000 Pro, it seems to be listed in the Unsupported Cameras section of the driver sourceforge page you linked to. The same section refers to using a different driver in that case.

gdesilva · 2012-06-09 10:39:06

@gibor - tried to translate the posts using Google Translate which did not make much sense at all! Could you kindly list the steps taken to overcome this issue? I removed pwc and inserted uvcvideo but that does not give a /dev/video0 device file. thanks.

@pipein, thanks for the alert. Just downloaded gspcav1-20071224.tar.gz which is the recommended driver. Will update the progress...

EDIT: wrong driver! it appears QC 4000 Pro drivers are virtually non-existent!

pipein · 2012-06-09 10:43:15

@gdesilva

(noting gibor's topic is a year old, however...)

In gibor's topic he provides another package (media-001.tazpkg):

http://www.freefilehosting.net/media-001

gibor mentioned that adding this on several pcs (live) helped webcam work 1st time.

Also in same topic nickname113 says "I just put the check mark on auto install optional packages or something like that and it worked smile "... probably meaning an option when running tazhw box.

gdesilva · 2012-06-09 11:15:49

@pipein, NBG! Installed media-001.tazpkg and set auto install optional packages in Tazhw Box - the latter caused installation of a number of additional packages but the camera is dead as a door nail. /dev/video0 file exists but vlc claims that it cannot open /dev/video0 (in capture mode). Checked to make sure tux is in video group.

gibor · 2012-06-09 11:49:23

Sorry

It means having the right driver package then you run the test from the command line with play webcam

mplayer tv:// -vo x11 driver=v4l2:device=/dev/video0

if it does not work then I'm wrong advice hmm

pipein · 2012-06-09 13:36:04

@gdesilva

yeah pwc seems to be the right (only) one to handle quickcam pro 4000 and you suspected it was broken. I don't have any webcam (let alone one using pwc) so I can't really test.

Long shot 1: check udev is correct version for your SliTaz version (170 for Slitaz 4.0 I think). I found udev had been updated to 182 somehow one time on my machine which seemed to cause a problem creating /dev/dri/card0. (well forcing reinstall of udev-170 fixed it anyway).

Long shot 2: did you happen to try selecting the WebCam button in tazhw box?

You might try seeing if /dev/video0 really is busy/in use by something else by using command fuser /dev/video0 in terminal. That might output a PID which you can look the for details of using using something likeps | grep XXXX where XXXX is that PID.

Could try disconnecting webcam, deleting /dev/video0 as root and rebooting. Then replugging webcam. Then try gibor's mplayer line.

Beyond that I'm afraid I'm not much help on this.

gdesilva · 2012-06-10 09:59:58

@gibor - thanks for the clarification. mplayer fails all the time.

@pipein, tried both options suggested by you. 1. I am running udev-170 and 2. did try to install via tazhw box. And no one is using /dev/video0 either.

However, my /var/log/messages clearly puts out an error message when the camera is plugged in as follows;

Jun 10 19:54:01 (none) user.info kernel: usb 1-2.6: new full speed USB device using ehci_hcd and address 10

Jun 10 19:54:01 (none) daemon.err udevd[1626]: bind failed: Address already in use
