Can't get picture form Logitech, Inc. Labtec Webcam Pro

Post by bresio » Thu Jun 25, 2015 12:15 pm

Hello
I can't get picture form Logitech, Inc. Labtec Webcam Pro and I don't know, where is the reason.

Code: Select all

$ lsusb
Bus 003 Device 002: ID 046d:0929 Logitech, Inc. Labtec Webcam Pro
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Code: Select all

$ uname -r
3.10.0-229.7.2.el7.x86_64

Code: Select all

# zmu -d /dev/video0 -q -v
Error, failed to enumerate standard 0: Success

Code: Select all

# zmu -d /dev/video0 -q -v -V1
Video Device: /dev/video0
In Monitor1 window, I can see only green screen with moving horizontal lines (I can's add photo cause of forum policy - my post looks too spamy for a new user, )

My settings for monitor 1:
Source Type: Local
Function: Monitor
Device Path: /dev/video0
Capture Method Video For Linux version 2
Device Channel: 1
Device Format: PAL
Capture Palette: *YUYV


In cheese, I can see normal picture form this cam.

What could be the problem?

Try messing around with resolution & color palette. You may need a different driver. FWIW I never got much joy from USB webcams.

Loaded video modules

Code: Select all

$ lsmod | grep video
videodev              126499  3 gspca_spca561,gspca_main
video                  19263  1 i915
i2c_core               40325  6 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,videodev
I've checked every combination of Capture Palette.

Cameras (I have two Labtec cameras) works fine in cheese program.
