What is an OGG?
Files with the extension .ogg denote an Ogg media file. Ogg is a patent-free open specification container format. It is often used as the container format for audio encoded using the open and patent-free Vorbis codec. Ogg files can also contain video encoded using the Theora codec, amongst other things. Theora is an open and royalty-free video codec.
Playback under Linux
The OGG files should playback without the installation of any additional software on most mainstream Linux distributions. The common FLOSS media players, Xine, Mplayer, Helix Player and Totem should play back the files without any problem. The following distros have been tested:
- Ubuntu Breezy and newer
- Fedora Core 4 and newer
OpenSUSE 10 and newer
- Debian 3.1 and newer (using Xine)
RedHat / White Box Enterprise Linux 4 and newer
- Gentoo (USE flags required 'vorbis theora ogg').
If you have problems playing these files, please raise it on the MailingList, giving details of the Linux distribution you are using and the versions of media player(s) you have tried.
Playback under Windows
Playing back an OGG file which uses Vorbis and Theora codecs requires the installation of additional software. The [[DirectShow filters]] for OGG allow playback of OGG files using Vorbis and Theora codecs. An alternative is to use VLC media player. If there is a WMV version of the video available, it might be simpler to use that.
