Yes in the deepest lawyering theory nobody can support HTML5 video until the standard is ratified... But in practice we can still say IE does not support it

Comparisons

The HTML5 video tag is a markup language tag introduced in HTML5 draft specification, adding support for embedding video in an HTML page.

As of February 2010, the Adobe Flash Player was widely used to embed video on web sites such as YouTube, since the majority of web browsers had Adobe's Flash Player installed (with notable exceptions such as the browser on the Apple iPhone and iPad). HTML5 video is intended by its creators to become the new normal way to show video online, but has been hampered by lack of agreement as to which video formats should be supported in the video tag.

Example

The following HTML5 code fragment will embed the Theora video in a web page. 

<video src="movie.ogv" controls="controls">
your browser does not support the video tag
</video>

Supported video formats

The current HTML5 draft specification does not specify which video formats browsers should support in the video tag. User agents are free to support any video formats they feel are appropriate.

Default video format debate

Main article: Use of Ogg formats in HTML5

It is desirable to specify at least one video format which all user agents (browsers) should support. The ideal format should:

  • Have good compression, good image quality, and low decode processor use.
  • Not be subject to any patents.
  • In addition to software decoders, a hardware video decoder should exist for the format, as many embedded processors do not have the performance to decode video.

H.264/MPEG-4 AVC is widely used, and has good speed, compression, hardware decoders, and video quality, but is covered by patents. There is however a well-established way to license the H.264 patents.

The free and open Ogg Theora is not covered by any known patents, but for example WHATWG has cited concerns over the Ogg formats being vulnerable to unknown patents[1]. Apple Computer have also opposed the inclusion of Ogg formats in the HTML standard on the grounds that H.264 performs better and is already more widely supported, citing patents and the lack of precedents of "Placing requirements on format support", even at the "SHOULD" level, in HTML specifications.[2]

Initially Ogg Theora was the recommended standard video format in HTML5, because it was not affected by any known patents. But on December 10, 2007, the HTML5 specification was updated[3], replacing the reference to concrete formats:

User agents should support Ogg Theora video and Ogg Vorbis audio, as well as the Ogg container format.

with a placeholder:[4]

It would be helpful for interoperability if all browsers could support the same codecs. However, there are no known codecs that satisfy all the current players: we need a codec that is known to not require per-unit or per-distributor licensing, that is compatible with the open source development model, that is of sufficient quality as to be usable, and that is not an additional submarine patent risk for large companies. This is an ongoing issue and this section will be updated once more information is available.[5]

The removal of the Ogg formats from the specification has been criticized by some Web developers.[6][7][8] A follow-up discussion also occurred on the W3C questions and answers blog.[9]

Usage

As of February 2010, HTML5 video is not currently as widespread as Flash videos, though recent rollouts of experimental HTML5-based video players from DailyMotion[26] (using Ogg Theora and Vorbis format), YouTube[27] and Vimeo[28] (using the H.264 format) suggest that interest in adopting HTML5 video is increasing.
