Webcam not working

Post by bluegroper » 2020/03/29 23:29:53

Hi forum
I'm trying to do the "work from home" thing.
Found an old Logitech webcam amongst the spares. Trying to get the camera working in CentOS (with KDE/Plasma desktop)
When I plug in the Webcam, I gets the following in dmesg :
# dmesg
[1299279.060795] usb 2-1.1: new full-speed USB device number 24 using ehci-pci
[1299279.143105] usb 2-1.1: New USB device found, idVendor=046d, idProduct=08d9, bcdDevice= 1.00
[1299279.143109] usb 2-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
[1299279.143466] gspca_main: gspca_zc3xx-2.14.0 probing 046d:08d9

And lsusb detects the device :
# lsusb
Bus 002 Device 024: ID 046d:08d9 Logitech, Inc. QuickCam IM/Connect
Not sure why hwinfo thinks its a TV card needing an audio driver ?
# hwinfo --usb

Pleases and thankyous for any tips or clues to get this working.
Or maybe its just too old and should be moved from spares box to physical trash bin.
I'm not a complete idiot. There's still a few pieces missing.

a quick test, try opening /dev/video0 with cheese, vlc, mplayer or mpv
For mpv (and probably mplayer) you can run from cli but vlc needs to open media > open capture device, I have a built in webcam so not sure if a usb one is still in /dev/video0
Also my webcam uses "video for linux" v4l2, I have libv4l and xorg-x11-drv-v4l installed and the cli output when played/quit with mpv says "[ffmpeg/demuxer] video4linux2,v4l2: Some buffers are still owned by the caller on close." which would suggest ffmpeg is also required.
Don't bother with totem/videos, I just can't get it to work.
Edit: ok I just found an old playstation 2 usb webcam and that is /dev/video1 and only seems to work with vlc.
