Webcam is not working on skype with Ubuntu 12.04

Question

I posted a week ago that I had solved the problem by downloading Skype 4.0 for Linux. However it turns out I spoke too soon. The video just freezes in Skype, though it is fine in Cheese, the Ubuntu webcam app. So I'm still high and dry and have to resort to booting Windows, darn it. I am running 64 bit Xubuntu 12.04 on an AMD quadcore system.

bash -c 'LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype'64 Bit
bash -c 'LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype'
https://help.ubuntu.com/community/Webcam/Troubleshooting Make a launcher and try either of the above. Below may help you.Copy and paste the line below into the Terminal and press Enter.sudo gedit /usr/local/bin/skypeThis will open your editor with a blank text file, copy and paste the following lines into your blank text file.Use lines below for x86(32bit)#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype Use lines below for x64(64bit)#!/bin/bash
LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so /usr/bin/skypeSave the file and close it.Now to make the file executable, copy and paste the following line into Terminal.sudo chmod a+x /usr/local/bin/skypePress Enter and close the Terminal, start Skype and webcam works.Now your webcam is working you can optionally (to improve the quality of your webcam picture), install v4l2ucp(video for linux 2 universal control panel) from the Software Manager.Type "v4l2ucp" in the search box and then select it.After installation go toMenu> Preferences > Video4Linux Control PanelThis will allow you to adjust the Contrast, Gamma, Auto Gain and Sharpness of your video. Simply click "Preview" and adjust the sliders to suit your requirements.If your webcam has a built-in microphone, to set it to default for use with Skype, go toMenu> Preferences > SoundClick on the input tab and select your webcam microphone from the choices listed for input devices.(Make sure microphone volume is not muted).As an alternative if the above fix does not work try using the lines below instead.Use lines below for x86(32bit)#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so /usr/bin/skype Use lines below for x64(64bit)#!/bin/bash

SkypeThis information might be for the old versions of Skype and obsolete in 2010 and laterGo to main menu, System, Preferences, Menus: Applications, Internet, Items: Skype, Properties, and replace the Command withbash -c 'LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype'1.1.1. 64-bitbash -c 'LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so skype'If you get an error similar to the following:ERROR: ld.so: object '/usr/......../v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored.Check the correct path to "v4l1compat.so" on your system: Go to the menu places, "search for files" and search for "v4l1compat.so" Then, substitute the right path into the previous commands as follows:bash -c 'LD_PRELOAD=/The/Right/Path/v4l2convert.so skype'If the above doesn't work then try running the command from a terminal and look at the output. If it is complaining about "error unexpected width / height in JPEG headerexpected: 320x240, header: 1600x1200" then try the followingbash -c 'LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype'1.1.2. 64-bitbash -c 'LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so skype'If the above even doesn't work then try the followingexport XLIB_SKIP_ARGB_VISUALS=1

bash -c 'LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so /usr/bin/skype'1.2. A clean start for skypeThis can be tidied up by writing a small script in /usr/local/bin called skype that comes higher in the loading sequence that the script of the same name in /usr/bin/. That script is in charge of running skype; the new script loads the correct libraries then hands control to the former script.In terminal type:$ sudo gedit /usr/local/bin/skypeand paste the following 2 line code snippet into gedit:LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
/usr/bin/skypesave and close. Now back in terminal make it executable$ sudo chmod a+x /usr/local/bin/skypeReboot type skype and the web cam just works. This was tested on Lucid with a Logitech Quick Cam Communicator.https://help.ubuntu.com/community/Webcam/Troubleshooting
