==Recording videos of your screen (screen video capture)==

===Introduction===

This article explains how to capture videos of your screen (you might want to post a video on YouTube, for instance). The two applications I have used are XVidCap (http://xvidcap.sourceforge.net/) and recordMyDesktop (http://recordmydesktop.sourceforge.net/about.php), both of which support audio recording as well as video recording so that you can create audio-visual tutorials and examples. Both applications are in Portage while only recordmydesktop is also in Entropy, both have Man pages, and you can also enter "xvidcap --help" and "recordmydesktop --help" in a Terminal window for information.

===XVidCap===

Enter "xvidcap" in a Terminal window to launch the GUI, which is self explanatory (hover your mouse pointer over the buttons to see the tooltips). I have some success with XVidCap but the Stop button often does not work and I have to click on the GUI's Close Window button to stop it recording. A file called e.g. test-0000.mpeg is created in my home directory; I can watch it using a multimedia player such as MPlayer, or convert it to another file format using ffmpeg.

===recordMyDesktop===

recordMyDesktop works better for me. To install it you may choose one of the following depending on whether you use Portage or Entropy to maintain your system:

Portage:
{{Console| <pre class="clear">
# USE="encode" emerge -1v libtheora
# emerge -1v recordmydesktop
# emerge -1v gtk-recordmydesktop</pre>}}

Entropy:
{{Console| <pre class="clear">
# equo install recordmydesktop gtk-recordmydesktop</pre>}}

You can use recordMyDesktop without a GUI front-end by launching it from the command line in a Terminal window (just enter "recordmydesktop", and press Ctrl-C to stop recording). However if you want a GUI, there are two alternatives: gtk-recordmydesktop and qt-recordmydesktop. You can choose to install either as both are in Portage. As you can see above, I plumped for gtk-recordmydesktop, and an icon gtk-recordMyDesktop was automatically installed under K Menu > Multimedia (alternatively you can launch it from the command line by entering "gtk-recordMyDesktop" in a Terminal window). The online user documentation for recordMyDesktop is good (see the URL above). recordMyDesktop creates a file with the default filename out.ogv in my home directory (you can select another filename with gtk-recordMyDesktop if you want). This file is an ogg container containing video encoded using the theora video codec and audio encoded using the vorbis audio codec. I can watch it using a multimedia player such as MPlayer, or convert it to another file format using ffmpeg.

===Convert output file to other formats===

To convert the output of xvidcap and recordMyDesktop to other video formats I use ffmpeg. For example, to convert the output file of recordMyDesktop to a Flash Video file I would use:

{{Console| <pre class="clear">
$ ffmpeg -i ~/out.ogv ~/Desktop/SL_tutorial.flv</pre>}}

Read the ffmpeg Man page for all the options available.
