The Ogg file format has been designed by Xiphophorous
? as a free and open alternative to multimedia formats such as
QuickTime and [Windows Media]
?.
As of November 2001, implementations support only the
Vorbis lossy audio codec, but developers continue to work on other codecs.
- Vorbis: perceptual lossy audio compression that has already surpassed MP3 in quality bit-for-bit
- Tarkin?: lossy video compression
- MNG: animation based on PNG and JPEG. Ogg MNG can potentially replace the various incompatible [motion JPEG]? systems in existence.
- XML: text, good for subtitles and captions
