The Xiph.Org Foundation is a 501(c)(3) non-profit organization dedicated to providing open and free-to-implement multimedia technology as a foundation for an interoperable, level playing field on the Internet and other digital distribution networks. Over the past 27 years we have developed most of the major patent-free and royalty-free audio and video codecs currently in use, including Opus, Vorbis, Speex, FLAC, Theora and most recently AV1, as well as developing the Ogg streaming format. Xiph also produces production quality software implementations including the Icecast streaming media server, and the rav1e encoder for the royalty-free AV1 video format.
