[Fedora] Watch video and listen to music in fedora 21

Please note that most of this software is potentially patent encumbered and therefore will not be included in the default official Fedora repositories. Please read this wiki page for more information: https://fedoraproject.org/wiki/Forbidden_items

Step 1:

Install RPM Fusion (Free & Non-Free) repositories:

su

dnf install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm

 

Step 2:
Install the multimedia codecs:


If you are using GNOME:

su -c 'yum install gstreamer{1,}-{ffmpeg,libav,plugins-{good,ugly,bad{,-free,-nonfree}}} ffmpeg'

If you are using KDE, you might prefer xine instead of Gstreamer:

su -c 'yum install xine-lib* k3b-extras-freeworld'

Step 3:
If you also plan to listen to internet radio streams via rhythmbox for example, you need a few more packages:

su -c 'yum install gstreamer{1,}-{plugin-crystalhd,ffmpeg,plugins-{good,ugly,bad{,-free,-nonfree,-freeworld,-extras}{-extras}}} ffmpeg libmpg123 lame-libs'

Step 4:
Install VLC media player:

su -c 'yum install vlc'

Good luck :)
