{{quote|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.<ref>{{cite mailing list |url=http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2007-December/013152.html |title=&#91;whatwg&#93; Removal of Ogg is *preposterous* |publisher=Lists.whatwg.org |date=11 December |accessdate=2009-08-25 |mailinglist=[[WHATWG]] |archiveurl=https://web.archive.org/web/20080821163038/http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2007-December/013152.html |archivedate=2008-08-21 |deadurl=yes |dfurl-status=dead }}</ref>}}

The removal of the Ogg formats from the specification made it completely file format neutral, like previous versions of HTML. The decision was criticized by a number of [[Web developer]]s. A follow-up discussion also occurred on the W3C questions and answers blog.<ref>{{cite web |url=http://www.w3.org/QA/2007/12/when_will_html_5_support_soone.html |title=When will HTML 5 support &lt;video&gt;?

In response to criticism, the [[WHATWG]] has cited concerns over the Ogg formats still being within patent lifetime and thus vulnerable to unknown patents.<ref>{{cite mailing list |url=http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2007-December/013154.html |title=Re: &#91;whatwg&#93; Removal of Ogg is *preposterous* |date=11 December 2007 |accessdate=2008-02-25 |mailinglist=whatwg mailing list |last=Hickson |first=Ian |archiveurl=https://web.archive.org/web/20080821194930/http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2007-December/013154.html |archivedate=21 August 2008 |deadurlurl-status=yesdead |df=dmy-all }}</ref>

Such [[submarine patent]]s may also exist for formats like [[MP3]]. Also, the [[H.264/MPEG-4 AVC|AVC]] patent licensing policy is subject to change in a not-yet-clear manner.<ref>{{cite news |last=Paul |first=Ryan |title=Decoding the HTML 5 video codec debate |work=Infinite Loop / The Apple Ecosystem |date=2009-07-05 |url=https://arstechnica.com/open-source/news/2009/07/decoding-the-html-5-video-codec-debate.ars |accessdate=2012-07-25}}</ref>

==Adoption==

{{As of|2010|May}}, HTML5 video is not currently as widespread as Flash videos, though of recent rollouts of experimental HTML5-based video players on websites, DailyMotion is so far the only one to use Ogg Theora and Vorbis formats,<ref>{{cite web |title=Watch Video…without Flash |publisher=Dailymotion |date=2009-05-27 |url=http://blog.dailymotion.com/index.php/2009/05/27/watch-videowithout-flash/ |accessdate=2010-05-18 |archive-url=https://web.archive.org/web/20100822205946/http://blog.dailymotion.com/index.php/2009/05/27/watch-videowithout-flash/ |archive-date=2010-08-22 |deadurl-url=yes |dfstatus=dead }}</ref> which suggests an increasing early interest in adopting HTML5 video.

"[[WebRTC]] Audio Codec and Processing Requirements" Internet standard drafts, published in 2011-2013, require free formats, including [[Opus (audio codec)|Opus]], which was developed, among others, by programmers associated with [[Xiph.Org Foundation]] (the maintainer of [[Ogg]]).<ref>http://tools.ietf.org/html/draft-ietf-rtcweb-audio-03</ref><ref>https://wiki.xiph.org/OpusFAQ</ref><!-- does WebRTC use Opus in Ogg? -->
