Free formats
From openSUSE Community Wiki
There are several multimedia formats that cannot be included on the openSUSE CDs/DVD because they are proprietary, patented, restricted formats. Some of these include MP3, MPEG-4, playing of encrypted DVDs, etc. In many cases you can use free formats instead.

Ogg
Ogg is a free, open standard container format maintained by the Xiph.Org Foundation. It is unrestricted by software patents and is designed to provide for efficient streaming and manipulation of high quality digital multimedia.
Being a container format, Ogg can embed audio and video in various formats, and usually Ogg is used with the following:
Audio
- Vorbis (lossy)- handles general audio data at mid- to high-level variable bitrates (~16-500 kbit/s/channel)
- FLAC (lossless) - handles archival and high fidelity audio data.
Video
- Theora - based upon On2's VP3, it is targeted at competing with MPEG-4 video (for example, encoded with DivX or Xvid), RealVideo, or Windows Media Video.
Software Freedom is important, please always use these when possible.
