Convert Youtube videos to audio in Linux

After reading Martin’s fine article “Download Youtube Videos” today, I had to give a bit of a Linux perspective and show how to do this in the Linux operating system. Inititially I assumed this would have to be done via the command line, because that is how I have always done conversions. But I have found that many people do not like having to do such tasks from the command line. So I sat out to find a good (and by “good” I mean easy). It didn’t take long to find, it didn’t take long to install, and it didn’t take too long to get working the way I wanted (which means including mp3 support).

The tool I eventually settled upon is Elltube. Of all the available tools this was the easiest to install, get working, and the most reliable. With this tool you will find download and converting Youtube videos a nobrainer. There is only one small hitch. If you want to add mp3 support you will have to do some extra installation (In this case it means installing unsupported files). The distribution I will use for this tutorial is Ubuntu 9.04. I will illustrate converting videos into audio-only mp3 format. This is the format that causes issues with most users due to the necessary installation of mp3-supporting libraries.

Preparing for the installation of Elltube

The good news is that everything you need, outside of Elltube itself, will be located in the default repositories. The bad news? You will have to install restricted applications. What this means is that Canonical is not responsible for the updating of these files. With that said you will need to fire up Synaptic. I do not suggest you just open up the Add/Remove Software utility from the menu. Instead open up a terminal window and issue the command:

sudo synaptic

The above command will open up the full-blown Synaptic tool where you will need to do the following:

  1. Search for “lame” (no quotes).
  2. Scroll down until you see the “ubuntu-restricted-extras”.
  3. Mark “ubuntu-restricted-extras” for installation.
  4. Search for “ffmpeg” (no quotes).
  5. Mark “ffmpeg” for installation.
  6. Click Apply to install.

Once all of this has installed download the Elltube .deb file and save it to your ~/ directory. After this file download has completed open up a terminal window and issue the following command to install:

sudo dpkg -i ~/elltube_0.3-1_all.deb

which will install Elltube. You are ready to convert.

Figure 1

You will find Elltube in your Internet sub-menu of either your Main or Applications menu. When the Elltube application opens you will see the Main window (see Figure1). There isn’t much to this application from the GUI perspective – but it serves the purpose well.

The first thing you need to do is find a video you want to convert on Youtube. Let’s convert a live version of Rush’s La Villa Strangiato. Find the URl and then copy and paste into the

Youtube URL area. When you do this the details of the file will appear in the main window (see Figure 2). Now what you have to do is to select MP3 (audio only) from the Format drop-down and select a Save to location for the download and conversion. When the details are done, click the Download button and the process will begin.

When the conversion process is complete the “Video found!” message will change to let you know it is finished. When it has completed you will have your mp3 file in the Save to folder. You are ready to rock!

Final thoughts

Elltube makes the downloading and conversion of Youtube videos as simple as it gets. The ease at which this process is done makes the installation well worth it.

Howto setup Second IP address or Virtual IP address to your Networkcard in ubuntu

If you are a Network Administrator some time you need to assign more than ONE ip address (second ipaddress) to your network card of Ubuntu machine. For this you need to edit the /etc/network/interfaces file by adding the following lines . See the example below and make change according to your ip address settings

#vi /etc/network/interfaces

auto eth0
iface eth0 inet static
address 192.168.0.5
netmask 255.255.255.0
network x.x.x.x
broadcast x.x.x.x
gateway x.x.x.x

auto eth0:1
iface eth0:1 inet static
address 192.168.0.50
netmask 255.255.255.0
network x.x.x.x
broadcast x.x.x.x
gateway x.x.x.x

after entering the values save this file and you need to restart networking services in ubuntu using the following command to take effect of our new ipaddress.

After entering all the details you need to restart networking services using the following command

#/etc/init.d/networking restart

Cheese: The Un-Cheesy Webcam Software for Linux Having tried Photo Booth on Mac OS X, I once wished to have that cool application on my Linux box. Th

Having tried Photo Booth on Mac OS X, I once wished to have that cool application on my Linux box. Then came Cheese, the GNOME application that is quite similar to that of Photo Booth. Utilizing GStreamer framework, it allows users to apply fantastic graphical effects while capturing photos or videos. Aside from the fun stuff, Cheese is loaded with handy little features.

I installed the latest version of Cheese, which is 2.26.0 on Ubuntu 9.04, and it works like a charm with my A4Tech (PK-730MJ) webcam. Cheese is available in all major distro repositories so Linux users should have no problem getting and installing it.

Cheese has a very simple and a no-nonsense graphical interface. If you want to take a photo, just click on the "Photo" button, then "Take a Photo". If you want to take a video, click on the “Video” button, then "Start/Stop Recording". You will see snapshots of the captured images and videos at the bottom where you can view them by double-clicking. By default, the captured images are saved at /home/username/Pictures/Webcam, while videos are saved at /home/username/Videos/Webcam.


Although not as plenty as those on Photo Booth, Cheese comes with a decent amount of unique visual effects that I’m happy with. Here's the current list of effects:

* Mauve

* Noir/Blanc

* Saturation

* Hulk

* Vertical Flip

* Horizontal Flip

* Shagadelic

* Vertigo

* Edge

* Dice

* Warp


You can also combine those effects by picking two or more of them, and then clicking on the "Effects" button to start recording videos or capturing photos with multiple effects.

Another good feature of Cheese is that it supports uploading of photos on Flickr provided that you have the "postr" package installed.

All in all, Cheese is a handy webcam application that should be installed by default on Ubuntu and on other popular distros because I can't think of any other webcam software for Linux that can rival even the basic functionality of Cheese. Although it will not turn your ordinary webcam into a security camera, it's very reliable, user-friendly, and it can be a lot of fun. I just hope that more fancy effects and useful features will be added to Cheese soon.

So what can you say about Cheese? Do you know of other webcam software for Linux that is better or is as good as Cheese?

WineXS – Simple graphical environment to configure Wine

Wine is an Open Source implementation of the Windows API on top of X and Unix.Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, and Solaris.

WineXS allows you to easily configure Wine by installing and removing software, editing the registry, managing files, and more.

Install WineXS in Ubuntu

first you need to download the file from where you want to run this installation in this example i am using /home/user

$cd /home/user

$wget http://tsx.nl/files/winexs-1.4.2.tgz

Now you need to extract .tgz file using the following command

$tar xvzf winexs-1.4.2.tgz

Now you should be having winexs directory now you need to go into this directory

$cd winexs

Run the following command to run winexs

$./winexs

Once it opens you should see similar to the following screen,Here you can install,remove software,install system files,wine configuration

Software Installation screen

Install System files screen

Wine configuration screen

This application is very easy and i personally like this.If you guys have any more tips on this please share here.
