In cases where decoders are not built into the browser, the format support will be dictated by the [[multimedia framework]] of the operating system. Consequently, browser support for multimedia formats are influenced by the problem that [[DirectShow]] and [[QuickTime]] does not support free formats like Theora by default, whereas [[GStreamer]] and [[Phonon (KDE)|Phonon]] cannot safely support other than free formats by default on the free operating systems that they are intended to run on.
* The empty table elements indicate dependence on backend. Note that the 3 uppermost browsers, which are true multiplatform browsers, have builtin decoders for specific formats, while browsers targeting mainly one operating system rely on backends.

* The backends [[DirectShow]] and [[QuickTime]] does not support free formats like Theora by default (as of may 2010), whereas [[GStreamer]] and [[Phonon_(KDE)|Phonon]] cannot safely support other than free formats by default on the free operating systems that they are intended to run on. While this incompatibility obviously impacts browsers that use backends, it is not a factual property of the browsers, since the user may install arbitrary codecs. Such normative information is omitted in this table.

HTML
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 April 2010, 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 controversial exceptions such as the browser on the Apple iPhone and iPad). HTML5 video is intended by its creators to become the new standard 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[according to whom?]:

  • Have good compression, good image quality, and low decode processor use.
  • Be royalty-free.
  • 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.

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,[1] replacing the reference to concrete formats:

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

with a placeholder:[2]

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.[3]

Although Theora is not affected by known patents, companies such as Apple and (reportedly) Nokia are concerned about unknown patents that might affect it, whose owners might be waiting for a corporation with deep pockets to use the format before suing.[4][5] Formats like H.264 might also be subject to unknown patents in principle, but they have been deployed much more widely and so it is presumed that any patent-holders would have already sued someone. Apple has also opposed requiring Ogg format support in the HTML standard (even as a "should" requirement) on the grounds that some devices might support other formats much more easily, and that HTML has historically not required particular formats for anything.[5]

Some web developers criticized the removal of the Ogg formats from the specification.[6][7][8] A follow-up discussion also occurred on the W3C questions and answers blog.[9]

H.264/MPEG-4 AVC is widely used, and has good speed, compression, hardware decoders, and video quality, but is covered by patents.[10] Except in particular cases, users of H.264 have to pay licensing fees to the MPEG LA, a group of patent-holders including Microsoft and Apple.[11] As a result, it has not been considered as a required default codec.

Google's acquisition of On2 will reportedly result in the open-sourcing of On2's proprietary codec, VP8, which would make it a possible option for HTML5 video.[12] Alternatively, rather than an open source license, which entitles users to also acquire the source code, Google may instead offer the codec royalty-free.[13]

In cases where decoders are not built into the browser, the format support will be dictated by the multimedia framework of the operating system. Consequently, browser support for multimedia formats are influenced by the problem that DirectShow and QuickTime does not support free formats like Theora by default, whereas GStreamer and Phonon cannot safely support other than free formats by default on the free operating systems that they are intended to run on.

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[30] (using Ogg Theora and Vorbis format), YouTube[31] and Vimeo[32] (using the H.264 format) suggest that interest in adopting HTML5 video is increasing.

As of April 2010, in the wake of Apple iPad launch, a number of high-profile sites have started to serve HTML5 video instead of Flash for user-agents identifying as iPad.[33]
