I would like to know how can I enable video and audio codecs not included by default on Ubuntu. Thanks!
Install this package via the command line:
sudo apt-get install ubuntu-restricted-extras
Installing this package will allow you to play MP3 files, and to decode various audio formats such as LAME. It will also allow you to use Microsoft fonts, install the Java Runtime Environment, Adobe Flash, and play DVDs.
sudo apt-get install gstreamer1.0-fluendo-mp3 gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav
gstreamer1.0-fluendo-mp3 provides decoding of MPEG 1 audio layer III streams,
gstreamer1.0-plugins-ugly are the gstreamer plugins and
gstreamer1.0-libav1 supports a large number of audio and video compression formats through the use of the libav library.
