Note that a video file normally contains both video and audio content, each encoded in its own format. The browser has to support both the video and audio formats. See HTML audio for a table of which audio formats are supported by each browser. The video format can be specified by MIME type in HTML (see example ).
The adoption of HTML5 audio, as with HTML5 video, has become polarized between proponents of free and patent-encumbered formats. In 2007, the recommendation to use Vorbis was retracted from the specification by the W3C together with that to use Ogg Theora, citing the lack of a format accepted by all the major browser vendors.

The development of the discrete cosine transform (DCT) lossy compression method leads to the first practical video formats, H.261 and MPEG, initially used for online video conferencing . 1993–2004.
Media Source Extensions ( MSE) is a W3C specification that allows JavaScript to send byte streams to media codecs within web browsers that support HTML5 video and audio. [5] Among other possible uses, this allows the implementation of client-side prefetching and buffering code for streaming media entirely in JavaScript.
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.
