Encoding video from one format to another isn't generally considered the most fun job in the world.

One of the video encoding tasks we need to do here for FOSSwire video posts is converting recordMyDesktop Ogg Theora video files into Flash format for the inline player (unfortunately, a necessarily evil).

Traditionally, this would mean dropping to the command line and hand-feeding the encoding instructions to a program like ffmpeg or mencoder.

Ubuntu user JeanClaude (also known as siafulinux) has put together a script for GNOME's File Manager (Nautilus) that makes the Theora to FLV encoding process really simple.

The script can be downloaded here and requires GNOME, Zenity and the video encoding tool mencoder to be installed.

Once you've downloaded the script, you simply extract the file, and double-click install in the extracted folder (choose Run if asked). This drops the script into the right folder.

Now, to convert an Ogg Theora video file to Flash, with default settings, you simply do the following.

Browse to the Ogg Theora source video.

Right-click the source video. On the menu, choose Scripts > Ogv to Flv Converter.

Wait while the conversion happens. When it's done, you will have a nice shiny Flash video file, ready for distributing via the web.

It really is an extremely simple and handy way to very quickly convert a video to Flash video and could easily save a lot of time if you're frequently working with video on Linux.

There are, obviously, plenty of situations where you want more control over the conversion settings, but as a quick two-click solution, Ogv to Flv is a win.

Kudos should go to the developer for making this little script not only really easy to use, but also very simple to install.

Gnac is a simple program for GNOME that allows you to convert audio files from one format to another.

It is built atop of the Gstreamer media framework, meaning that you can import any files that Gstreamer is capable of playing and then output to Gnac's supported formats for the conversion.

Once you've installed the program, it appears under the Sound & Video category, where you can launch it.

The interface is extremely simple. Use the Add button, or drag in a set of input files that you want to convert. Then select the output format from the list box at the bottom. Once you've done that, press the Convert button.

The default export options allow you to convert to Ogg/Theora and FLAC as well as WAV and Speex. While the number of export formats built in by default is nowhere near as high as with some programs, particularly those based upon ffmpeg, keeping just a few formats does keep the application simple.

For those people familiar with Gstreamer, it is possible to add to that list and add a new 'audio profile' with custom settings, so you are not strictly limited to those audio export formats.

Despite that limitation, Gnac is an effortlessly simple program with a great interface and could come in extremely handy if you're trying to batch convert a music collection to FLAC or Theora, for example.

The ability to drag a whole load of files in, choose the format and click Convert and then just leave it doing its work makes it perfect for batch jobs.

Gnac 0.1.1 has recently been released, packages for your distribution along with source code to build yourself can be downloaded from here.
