Use the HTML
<video> element to embed video content in a document. The video element contains one or more video sources. To specify a video source, use either the
src attribute or the
<source> element; the browser will choose the most suitable one.
For a list of supported formats, see Media formats supported by the audio and video elements.

Like all other HTML elements, this element supports the global attributes.
- A Boolean attribute; if specified, the video automatically begins to play back as soon as it can do so without stopping to finish loading the data.
Note: Some versions of Chrome only acknowledge
autostart, rather than
- An attribute you can read to determine the time ranges of the buffered media. This attribute contains a
- If this attribute is present, the browser will offer controls to allow the user to control video playback, including volume, seeking, and pause/resume playback.
- This enumerated attribute indicates whether to use CORS to fetch the related image. CORS-enabled resources can be reused in the
<canvas>element without being tainted. The allowed values are:
- Sends a cross-origin request without a credential. In other words, it sends the
Origin:HTTP header without a cookie, X.509 certificate, or performing HTTP Basic authentication. If the server does not give credentials to the origin site (by not setting the
Access-Control-Allow-Origin:HTTP header), the image will be tainted, and its usage restricted.
- Sends a cross-origin request with a credential. In other words, it sends the
Origin:HTTP header with a cookie, a certificate, or performing HTTP Basic authentication. If the server does not give credentials to the origin site (through
Access-Control-Allow-Credentials:HTTP header), the image will be tainted and its usage restricted.
Origin:HTTP header), preventing its non-tainted used in
<canvas>elements. If invalid, it is handled as if the enumerated keyword anonymous was used. See CORS settings attributes for additional information.
- The height of the video's display area, in CSS pixels.
- A Boolean attribute; if specified, we will, upon reaching the end of the video, automatically seek back to the start.
- A Boolean attribute which indicates the default setting of the audio contained in the video. If set, the audio will be initially silenced. Its default value is false, meaning that the audio will be played when the video is played.
TimeRangesobject indicating all the ranges of the video that have been played.
- This enumerated attribute is intended to provide a hint to the browser about what the author thinks will lead to the best user experience. It may have one of the following values:
none: indicates that the video should not be preloaded.
metadata: indicates that only video metadata (e.g. length) is fetched.
auto: indicates that the whole video file could be downloaded, even if the user is not expected to use it.
- the empty string: synonym of the
If not set, its default value is browser-defined (i.e. each browser may have its default value). The spec advises it to be set to
autoplayattribute has precedence over
autoplayis specified, the browser would obviously need to start downloading the video for playback.
- The specification does not force the browser to follow the value of this attribute; it is a mere hint.
- A URL indicating a poster frame to show until the user plays or seeks. If this attribute isn't specified, nothing is displayed until the first frame is available; then the first frame is shown as the poster frame.
- The URL of the video to embed. This is optional; you may instead use the
<source>element within the video block to specify the video to embed.
- The width of the video's display area, in CSS pixels.
<video> element can fire many different events.
<!-- Simple video example --> <video src="videofile.webm" autoplay poster="posterimage.jpg"> Sorry, your browser doesn't support embedded videos, but don't worry, you can <a href="videofile.webm">download it</a> and watch it with your favorite video player! </video> <!-- Video with subtitles --> <video src="foo.webm"> <track kind="subtitles" src="foo.en.vtt" srclang="en" label="English"> <track kind="subtitles" src="foo.sv.vtt" srclang="sv" label="Svenska"> </video>
The first example plays a video, starting playback as soon as enough of the video has been received to allow playback without pausing to download more. Until the video starts playing, the image "posterimage.jpg" is displayed in its place.
The second example allows the user to choose between different subtitles.
Multiple Sources Example
<video width="480" controls poster="https://archive.org/download/WebmVp8Vorbis/webmvp8.gif" > <source src="https://archive.org/download/WebmVp8Vorbis/webmvp8.webm" type="video/webm"> <source src="https://archive.org/download/WebmVp8Vorbis/webmvp8_512kb.mp4" type="video/mp4"> <source src="https://archive.org/download/WebmVp8Vorbis/webmvp8.ogv" type="video/ogg"> Your browser doesn't support HTML5 video tag. </video>
You can try the preceding example on HTML5 video demo example with live preview code editor.
If you use Apache Web Server to serve Ogg Theora videos, you can fix this problem by adding the video file type extensions to "video/ogg" MIME type. The most common video file type extensions are ".ogm", ".ogv", or ".ogg". To do this, edit the "mime.types" file in "/etc/apache" or use the "AddType" configuration directive in httpd.conf.
AddType video/ogg .ogm AddType video/ogg .ogv AddType video/ogg .ogg
If you serve your videos as WebM, you can fix this problem for the Apache Web Server by adding the extension used by your video files (".webm" is the most common one) to the MIME type "video/webm" via the "mime.types" file in "/etc/apache" or via the "AddType" configuration directive in httpd.conf.
AddType video/webm .webm
Your web host may provide an easy interface to MIME type configuration changes for new technologies until a global update naturally occurs.
