Playing music and videos

82.

Ubuntu includes applications for playing and managing music and for playing and editing video.

83.

Music and video files require special software to play them, called <emphasis>codecs</emphasis>. Some codecs (for example those required to play MP3s) are not included by default in Ubuntu because they are <ulink url="ghelp:add-applications#restricted-software">proprietary</ulink>. You will be prompted to add support for the necessary codec if you try to play a music or video file which is not supported.

84.

To add support for all frequently used music and video files, <ulink url="apt:ubuntu-restricted-extras">install the ubuntu-restricted-extras package</ulink>. This will also add support for <ulink url="ghelp:musicvideophotos#video-playback-flash">websites which use Flash video</ulink>.

For more instructions about playing music and videos, see <ulink url="ghelp:musicvideophotos">Music, Video and Photos</ulink>.

Keeping updated

87.

Ubuntu delivers security and other updates to your software automatically.

88.

When security updates are available, the <application>Update Manager</application> automatically starts up. For other updates you will be prompted once a week. To install updates, just click <guibutton>Install Updates</guibutton> and enter your password when prompted.

89.

Depending on the software which has been updated, Ubuntu may prompt you to restart your system.
