Webcam help

Meister · 2010-06-23 03:00:32

I've followed everything regarded in the Wiki for webcams. I'm using a Quickcam Pro 4000, have the pwc in my rc.conf, etc.

dmesg | tail

pwc: Logitech QuickCam 4000 Pro USB webcam detected.
pwc: Registered as video0.

I've tried using emesene, it doesn't even recognize my webcam. I've also tried guvcview, and all I get is a black screen, but the light on my webcam lights up. Here's some output from it.

guvcview 1.3.1

Not really sure what to make of this, any suggestions as to how I can get this working?

Did you try the LD_PRELOAD vars?

http://wiki.archlinux.org/index.php/Web … our_webcam

Last time i had problems with a webcam, those solved my problems.

Meister · 2010-06-25 22:23:49

Yep, I've tried those LD_PRELOAD vars, and it didn't help. Still a black screen on guvcview.

Meister · 2010-07-17 21:55:59

Sorry if bumping this is not allowed, but it's been quite a long time and unfortunatly I still can't figure out why my webcam won't run. Any more suggestions would be greatly appreciated.

You could use MPlayer to test if the webcam works.

mplayer tv:// -tv driver=v4l2:device=/dev/video0 &

Meister · 2010-07-18 01:30:42

Well I just downloaded mplayer, but trying that gives me this:

[matt@LinuxElite ~]$ mplayer tv:// -tv driver=v4l2:device=/dev/video0 &
[1] 10045
[matt@LinuxElite ~]$ MPlayer SVN-r31630-4.5.0 (C) 2000-2010 MPlayer Team
156 audio & 340 video codecs
mplayer: could not connect to socket
mplayer: No such file or directory
Failed to open LIRC support. You will not be able to use your remote control.

Idk if this has to do with just dling mplayer and not configuring it correctly, or if it's just another sign of my webcam not working.

awkwood · 2010-07-18 01:43:35

Not sure if it's a dependency of MPlayer, but do you have libv4l installed?
Also check to see if /dev/video0 exists on your machine.

Meister · 2010-07-18 03:51:20

Yep, libv4l is installed, and /dev/video0 exists.

[matt@LinuxElite dev]$ v4l-conf
