<p><span class="seoSummary">{{ HTMLElement("audio") }} и {{ HTMLElement("video") }} элементы предоставляют поддержку для проигрывания аудио и видео медиа без нужды в плагинах. </span>Формат медиафайла состоит из контейнера, содержащего один или несколько потоков данных, закодированных с использованием формата сжатия, называемого кодеком. Контейнер идентифицируется по расширению файла. Потоки внутри контейнера имеют несколько типов, которые могут включать в себя видео, аудио, данные или титры. Один контейнер (т. е. медиафайл) может содержать несколько потоков одного типа. В аудио- и видео- потоках находятся кодеки. Кодек — сокращенние слов "кодера-декодер" — является алгоритмом сжатия данных в файле. Каждый тип контейнера имеет только определенные кодеки, которые он поддерживает.</p>

<p>Важно понять, почему в Интернете нужны разные медиаформаты. По разным причинам, выходящим за рамки данной статьи, различные браузеры поддерживают разные медиаформаты. Кроме того, область медиаформатов в Интернете сильно пострадала от патентного права во многих странах, включая США и страны ЕС. (Примечания к патентам в этой статье предоставляются как есть, так и без каких-либо гарантий.) В этой статье рассматриваются наиболее важные для Интернета форматы, включая поддержку в браузерах как мобильных, так и десктопных .</p>

<h3 id="Отображение_медиа">Отображение медиа</h3>

<p> </p>

<p>Ниже краткий обзор того, как медиа-элементы отображаются в HTML. Более подробную информацию смотрите в статьях для каждого элемента.</p>

<p>HTML5 поддерживает несколько элементов мультимедиа. Элементы {{HTMLElement ("video")}} и {{HTMLElement ("audio")}} могут использоваться отдельно или в сочетании с элементом {{HTMLElement ("source")}}. Наш краткий пример отображает это. Хотя элементы <code>&lt;video&gt;</code> и <code>&lt;audio&gt;</code> содержат атрибуты src, этот пример использует  элемент <code>&lt;source&gt;</code> для предоставления видеофайлов в нескольких форматах, позволяя каждому браузеру выбирать элемент, который он поддерживает.</p>

<pre class="brush: html">&lt;video controls&gt;
  &lt;source src="somevideo.webm" type="video/webm"&gt;
  &lt;source src="somevideo.mp4" type="video/mp4"&gt;
  Сожалею; ваш браузер не поддерживает HTML5 видео в WebM с VP8 или MP4 с H.264.
  &lt;!-- Ты можешь встроить флеш плеер сюда, для воспроизведения твоего mp4 видео в старых браузерах --&gt;
&lt;/video&gt;
</pre>

<h2 id="WebM">WebM</h2>

<p>Формат <a class="external" href="http://www.webmproject.org/" title="http://www.webmproject.org/">WebM</a> основан на ограниченной версии формата контейнера <a class="external" href="http://corecodec.com/products/matroska" title="http://corecodec.com/products/matroska">Matroska</a>. Формат всегда использует видео кодек VP8 или VP9 и аудио кодек Vorbis или Opus. WebM нативно поддерживается в десктопной и мобильной версиях Gecko (Firefox), Chrome и Opera. Поддержка формата может быть добавлена в Internet Explorer и Safari (но не на iOS) установкой плагина. Нативная поддержка VP9 WebM в Edge сейчас в стадии разработки.</p>

<p>Формат WebM, а точнее видеокодек VP8, подвергся претензиям в нарушениях патентов от ряда компаний, отвечающих на требования, MPEG LA о фомировании списка патентов, но при этом <a href="http://www.businesswire.com/news/home/20130307006192/en/Google-MPEG-LA-Announce-Agreement-Covering-VP8">MPEG LA дала согласие на лицензирование этих патентов для Google</a> под лицензией "<a href="http://xiphmont.livejournal.com/59893.html?thread=310261#t310261">perpetual, transferable, royalty free license"</a>.  Это фактически означает, что все известные патенты, относящиеся к формату WebM лицензированы для свободного использования всеми.</p>

<p>Движок Gecko распознаёт следующие типы MIME как файлы WebM:</p>

<dl>
 <dt><code>video/webm</code></dt>
 <dd>файл WebM, содержащий видео (а возможно, также и аудио).</dd>
 <dt><code>audio/webm</code></dt>
 <dd>Файл WebM, содержащий только аудиоданные.</dd>
</dl>

<h2 id="Ogg_Theora_Vorbis">Ogg Theora Vorbis</h2>

<p>The Ogg container format with the Theora video codec and the Vorbis audio codec is supported in desktop/mobile Gecko (Firefox), Chrome, and Opera, and support for the format can be added to Safari (but not on iOS) by installing an add-on. The format is not supported in Internet Explorer in any way.</p>

<p>WebM is generally preferred over Ogg Theora Vorbis when available, because it provides a better compression to quality ratio and is supported in more browsers. The Ogg format can however be used to support older browser versions (for example Firefox 3.5/3.6 don't support WebM, but do support Ogg.)</p>

<p>The patent situation of Theora is similar to that of WebM.</p>

<p>You can learn more about creating Ogg media by reading the <a class="external" href="http://en.flossmanuals.net/ogg-theora/" title="http://en.flossmanuals.net/ogg-theora/">Theora Cookbook</a>.</p>

<p>Gecko recognizes the following MIME types as Ogg files:</p>

<dl>
 <dt><code>audio/ogg</code></dt>
 <dd>An Ogg file containing only audio.</dd>
 <dt><code>video/ogg</code></dt>
 <dd>An ogg file containing video (and possibly also audio).</dd>
 <dt><code>application/ogg</code></dt>
 <dd>An Ogg file with unspecified content. Using one of the other two MIME types is preferred, but you can use this if you don't know what the contents of the file are.</dd>
</dl>

<h2 id="Ogg_Opus">Ogg Opus</h2>

<p>The Ogg container can also contain audio encoded using the <a class="external" href="http://www.opus-codec.org/" title="http://www.opus-codec.org/">Opus codec</a>. Support for this is available in Gecko 15.0 {{ geckoRelease("15.0") }} and later, on desktop and mobile browsers.</p>

<h2 id="MP4_H.264_(AAC_or_MP3)">MP4 H.264 (AAC or MP3)</h2>

<p>The MP4 container format with the H.264 video codec and the AAC audio codec is natively supported by desktop/mobile Internet Explorer, Safari and Chrome, but Chromium and Opera do not support the format. IE and Chrome also support the MP3 audio codec in the MP4 container, but Safari does not. Firefox/Firefox for Android/Firefox OS supports the format in some cases, but only when a third-party decoder is available, and the device hardware can handle the profile used to encode the MP4.</p>

<div class="note">
<p><strong>Note</strong>: MP4s encoded with a high profile will not run on lower end hardware, such as low end Firefox OS phones.</p>
</div>

<p>The MPEG media formats are covered by patents, which are not freely licensed. All the necessary licenses can be bought from MPEG LA. Since H.264 is currently not a royalty free format, it is unfit for the open web platform, according to Mozilla [<a class="external" href="http://shaver.off.net/diary/2010/01/23/html5-video-and-codecs/" title="http://shaver.off.net/diary/2010/01/23/html5-video-and-codecs/">1</a>, <a class="external" href="http://robert.ocallahan.org/2010/01/video-freedom-and-mozilla_23.html" title="http://robert.ocallahan.org/2010/01/video-freedom-and-mozilla_23.html">2</a>], Google [<a class="external" href="http://blog.chromium.org/2011/01/html-video-codec-support-in-chrome.html" title="http://blog.chromium.org/2011/01/html-video-codec-support-in-chrome.html">1</a>, <a class="external" href="http://blog.chromium.org/2011/01/more-about-chrome-html-video-codec.html" title="http://blog.chromium.org/2011/01/more-about-chrome-html-video-codec.html">2</a>] and Opera. However, since royalty free formats are not supported by Internet Explorer and Safari, <a href="https://hacks.mozilla.org/2012/03/video-mobile-and-the-open-web/" title="https://hacks.mozilla.org/2012/03/video-mobile-and-the-open-web/">Mozilla has decided to support the format anyway</a>, and Google never fulfilled their promise to <span class="external">remove support for it in Chrome</span>.</p>

<h2 id="MP3">MP3</h2>

<p>MP3 аудио формат (.mp3, <code>audio/mpeg</code>; в отличии от выше MP3 аудио в случае MP4 контейнера) поддерживается в <code>&lt;audio&gt;</code> Firefox/Firefox для Android/Firefox OS когда операционая система обеспечивает MP3 декодер, и Internet Explorer, Chrome и Safari.</p>

<h2 id="WAVE_PCM">WAVE PCM</h2>

<p>The WAVE container format, with the PCM audio codec (WAVE codec "1") is supported by desktop/mobile Gecko (Firefox) and Safari. Files in the WAVE container format typically end with the ".wav" extension.</p>

<div class="note"><strong>Note: </strong>See <a class="external" href="http://www.rfc-editor.org/rfc/rfc2361.txt" title="http://www.rfc-editor.org/rfc/rfc2361.txt">RFC 2361</a> for the WAVE codec registry.</div>

<p>Gecko recognizes the following MIME types as WAVE audio files:</p>

<ul>
 <li><code>audio/wave</code> (preferred; does not work in Chrome)</li>
 <li><code>audio/wav</code></li>
 <li><code>audio/x-wav</code></li>
 <li><code>audio/x-pn-wav</code></li>
</ul>

<h2 id="Media_Source_Extensions_(MSE)">Media Source Extensions (MSE)</h2>

<p><a href="https://dvcs.w3.org/hg/html-media/raw-file/tip/media-source/media-source.html">Media Source Extensions</a> is a W3C working draft that plans to extend {{ domxref("HTMLMediaElement") }} to allow JavaScript to generate media streams for playback. Allowing JavaScript to generate streams facilitates a variety of use cases like adaptive streaming and time shifting live streams. This currently has experimental support in Firefox desktop, and other browsers too.<br>
 <br>
 For example,  <a href="http://msopentech.com/blog/2014/01/03/streaming_video_player/">you could implement MPEG-DASH using JavaScript while offloading the decoding to MSE</a>.</p>

<div class="note">
<p><strong>Note</strong>: Time Shifting is the process of consuming a live stream some time after it happened.</p>

<p>Notes:</p>

<ul>
 <li>AAC is only supported in the MP4 container.</li>
 <li>Opera Mini itself doesn't support any video or audio, but any video or audio is passed to the device to play if it has support for that format. Opera Mobile also does this with unsupported formats.</li>
 <li>To get the default Android browser to play H.264 video, you need to jump through some hoops, as <a href="http://www.broken-links.com/2010/07/08/making-html5-video-work-on-android-phones/">explained by Peter Gasston</a>.</li>
 <li>In Firefox OS 1.0.1, when detecting <code>&lt;video&gt;</code> support for different formats, <code>HTMLMediaElement.prototype.canPlayType</code> incorrectly reports <code>true</code> for h.264 video whereas in actual fact h.264 is not supported. In Firefox OS 1.1 this problem has been fixed.</li>
 <li>To avoid patent issues, support for MPEG 4, H.264, MP3 and AAC is not built directly into Firefox on desktop and mobile (Android and Firefox OS). Instead it relies on support from the OS or hardware (the hardware also needs to be able to support the profile used to encode the video, in the case of MP4). Firefox desktop supports these formats on the following platforms:</li>
