The HTML5 draft specification adds video and audio elements for embedding video and audio in HTML documents.The specification had formerly recommended support for playback of Theora video and Vorbis audio encapsulated in Ogg containers to provide for easier distribution of audio and video over the internet by using open standards, but the recommendation was soon after dropped.
