Layout engine support

The HTML5 draft specification defines several tags which allow video and audio to be included natively and semantically in HTML markup. This page compares support for aspects of this specification among layout engines.

Explanation of the tables[edit]

Engine nomenclature[edit]

Rather than the names of web browsers and HTML to PDF converters, the names of the underlying engines are used. Some of the software and online converters that use the various engines are listed below.

Values[edit]

Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.

Value Meaning
Yes Indicates that the layout engine fully supports this property/element when valid values are used.
No Indicates that the property/element is completely ignored.
Partial Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly.
Incorrect Indicates that the property/element is understood, but that it is not implemented correctly in all cases.
Experimental Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy.
Dropped Indicates that the property/element is no longer supported.
Nightly build Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected.
Depends Indicates that the property/element is supported only on certain platforms, or if certain settings are configured.

Element attributes[edit]

Media elements allow some attributes to be set directly in the tag.

Notes[edit]

  1. ^ a b c d e Supports preload under the older name autobuffer.
  2. ^ a b c d Google released a WebM component for Media Foundation to allow the playback of WebM files in IE9 through the standard HTML5 <video> tag.[t 5] Xiph.org distributes OpenCodecs package, which amends Google's VP8 decoder with DirectShow-based codecs for Ogg Theora and Ogg Vorbis. VLC media player comes with "Web plugin" that uses VLC for playing multimedia from <video> and <audio> tags, enabling support for all formats VLC supports.
  3. ^ a b c d e f WebKit on Mac OS X uses QuickTime, and supports whatever formats that does.[w 4] By default, this includes H.264, MP3, AAC and WAV PCM, but not Ogg Theora or Vorbis. These are supported only if installed as third-party codecs, such as XiphQT. Google Chrome supports Theora, Vorbis, WebM, and MP3.[w 5] Chromium can be compiled to support anything that FFmpeg supports, and may or may not support patented formats such as H.264 and MP3.[w 6] Origyn Web Browser for MorphOS uses also FFmpeg for playing HTML5 media content.[w 7][w 8]
  4. ^ a b On Linux and FreeBSD, Presto 2.5 uses the system version of the GStreamer library, and is able to play any formats supported by GStreamer (including H.264, MP3, AAC and others, if codecs are installed). On other platforms, it only supports Ogg Theora for video; and Ogg Vorbis and WAVE PCM for sound.[p 2]
