How to setup Video calls in Skype on 64-bit Ubuntu system

Skype is a software to make free video and voice calls, send instant messages and share files with other Skype users. You can use Skype in almost famous platforms: Windows, Linux, Mac OS and for your mobiles as well. For Linux users, you can easily download and install Skype binary package from here.

With the 32-bit Ubuntu box, you simply just plug Webcam or use build-in webcam, turn Skype and enjoy chatting with your girlfriend, however with the 64-bit counterpart, you have to do some tricks to make it works. Otherwise, you can’t see anything even you still can see camera file in /dev/video0

1. You have to locate v4l1compat.so library in your system. User Terminal and type this:

$ find / -name v4l1compat.so 2>/dev/null
/usr/lib/libv4l/v4l1compat.so
/usr/lib32/libv4l/v4l1compat.so

Use /dev/null to ignore errors can appear during searching for that lib.

2. You then have to load that library before other Skype libs by using LD_PRELOAD. You can read this article to see how LD_PRELOAD works: Modifying a Dynamic Library Without Changing the Source Code

So now create a file in anywhere you like with this folowing content:

#!/bin/bash
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype

And don’t forget to set execute permission to that file (chmod u+x ./yourfile).

    My developer is trying to convince me to move to .
    net from PHP. I have always disliked the idea because of the expenses.
    But he’s tryiong none the less. I’ve been using Movable-type on numerous websites
    for about a year and am worried about switching to another platform.
    I have heard good things about blogengine.
    net. Is there a way I can import all my wordpress posts into it?
    Any kind of help would be really appreciated!

    Hello just wanted to give you a quick heads up. The words in
    your content seem to be running off the screen in Opera. I’m not sure if this is a format issue or something to do with internet browser compatibility but I thought I’d post
    to let you know. The design look great though! Hope you
    get the problem resolved soon. Kudos
