Arista Transcoder (http://www.transcoder.org/) is a useful transcoder tool build upon Python and GStreamer. It’s not available in Fedora yum repositories, but the installation from source is quite easy.
First: download the sources from its website and untar them
[daniele@sam ~]$ wget http://programmer-art.org/media/releases/arista-transcoder/arista-0.9.7.tar.gz; tar xzvf arista-0.9.7.tar.gz
Second: install the dependencies required to build and install Arista and the extra GStreamer plugins (if not already installed) via yum
[daniele@sam ~]$ sudo yum -y install python3-devel gstreamer-ffmpeg gstreamer-plugins-good gstreamer-plugins-bad-free gstreamer-plugins-bad-nonfree gstreamer-plugins-ugly
Arista uses HAL which is deprecated since Fedora 15 and removed from Fedora 16, so to run Arista you also need to install python-gudev which uses udev instead of HAL.
[daniele@sam ~]$ sudo yum -y install python-gudev
Third: build and install the software and remove install sources
[daniele@sam ~]$ cd arista-0.9.7 [daniele@sam arista-0.9.7]$ python setup.py build [daniele@sam arista-0.9.7]$ sudo python setup.py install [daniele@sam arista-0.9.7]$ cd ~; rm -Rf arista-0.9.7
Fourth: run Arista from command line or from your application menu!
[daniele@sam ~]$ arista-gtk
