<video>: The Video Embed element
The <video> HTML element embeds a media player which supports video playback into the document. You can use <video> for audio content
as well, but the <audio> element may provide a more appropriate user experience.

The above example shows simple usage of the <video> element. In a similar manner to the <img> element, we include a path to the media we
want to display inside the src attribute; we can include other attributes to specify information such as video width and height, whether we
want it to autoplay and loop, whether we want to show the browser's default video controls, etc.
The content inside the opening and closing <video></video> tags is shown as a fallback in browsers that don't support the element.
Attributes
Like all other HTML elements, this element supports the global attributes.
autoplay
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: Sites that automatically play audio (or videos with an audio track) can be an unpleasant experience for users, so should be
avoided when possible. If you must offer autoplay functionality, you should make it opt-in (requiring a user to specifically enable it).
However, this can be useful when creating media elements whose source will be set at a later time, under user control. See our
autoplay guide for additional information about how to properly use autoplay.

<video>: The Video Embed element - HTML: HyperText Markup Language | MDN
To disable video autoplay, autoplay="false" will not work; the video will autoplay if the attribute is there in the <video> tag at all. To remove
autoplay, the attribute needs to be removed altogether.
In some browsers (e.g. Chrome 70.0) autoplay doesn't work if no muted attribute is present.
controls
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.
controlslist
The controlslist attribute, when specified, helps the browser select what controls to show for the video element whenever the browser
shows its own set of controls (that is, when the controls attribute is specified).
The allowed values are nodownload , nofullscreen and noremoteplayback .
Use the disablepictureinpicture attribute if you want to disable the Picture-In-Picture mode (and the control).
crossorigin
This enumerated attribute indicates whether to use CORS to fetch the related video. CORS-enabled resources can be reused in the <canvas>
element without being tainted. The allowed values are:
anonymous
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-ControlAllow-Origin: HTTP header), the resource will be tainted, and its usage restricted.
use-credentials
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-AllowCredentials: HTTP header), the resource will be tainted and its usage restricted.
When not present, the resource is fetched without a CORS request (i.e. without sending the Origin: HTTP header), preventing its nontainted use in <canvas> elements. If invalid, it is handled as if the enumerated keyword anonymous was used. See CORS settings attributes for
additional information.
disablepictureinpicture
Prevents the browser from suggesting a Picture-in-Picture context menu or to request Picture-in-Picture automatically in some cases.
disableremoteplayback
A Boolean attribute used to disable the capability of remote playback in devices that are attached using wired (HDMI, DVI, etc.) and wireless
technologies (Miracast, Chromecast, DLNA, AirPlay, etc.).
In Safari, you can use x-webkit-airplay="deny" as a fallback.
height
The height of the video's display area, in CSS pixels (absolute values only; no percentages ).
loop
A Boolean attribute; if specified, the browser will automatically seek back to the start upon reaching the end of the video.

<video>: The Video Embed element - HTML: HyperText Markup Language | MDN
muted
A Boolean attribute that 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.
playsinline
A Boolean attribute indicating that the video is to be played "inline", that is within the element's playback area. Note that the absence of this
attribute does not imply that the video will always be played in fullscreen.
poster
A URL for an image to be shown while the video is downloading. 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.
preload
This enumerated attribute is intended to provide a hint to the browser about what the author thinks will lead to the best user experience
regarding what content is loaded before the video is played. 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 can be downloaded, even if the user is not expected to use it.
empty string: Synonym of the auto value.
The default value is different for each browser. The spec advises it to be set to metadata .
Note:
The autoplay attribute has precedence over preload . If autoplay is 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.
src
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.
width
The width of the video's display area, in CSS pixels (absolute values only; no percentages ).

Usage notes
Browsers don't all support the same video formats; you can provide multiple sources inside nested <source> elements, and the browser will
then use the first one it understands.
HTML
<video controls>
<source src="myVideo.webm" type="video/webm" />
<source src="myVideo.mp4" type="video/mp4" />
<p>
Your browser doesn't support HTML video. Here is a
<a href="myVideo.mp4" download="myVideo.mp4">link to the video</a> instead.
</p>
</video>
We offer a substantive and thorough guide to media file types and the guide to the codecs supported for video. Also available is a guide to
audio codecs that can be used with them.

Other usage notes:
<video>: The Video Embed element - HTML: HyperText Markup Language | MDN
If you don't specify the controls attribute, the video won't include the browser's default controls; you can create your own custom
controls using JavaScript and the HTMLMediaElement API. See Creating a cross-browser video player for more details.
To allow precise control over your video (and audio) content, HTMLMediaElement s fire many different events. In addition to providing
controllability, these events let you monitor the progress of both download and playback of the media, as well as the playback state and
position.
You can use the object-position property to adjust the positioning of the video within the element's frame, and the object-fit property to
control how the video's size is adjusted to fit within the frame.
To show subtitles/captions along with your video, you can use some JavaScript along with the <track> element and the WebVTT format.
See Adding captions and subtitles to HTML video for more information.
You can play audio files using a <video> element. This can be useful if, for example, you need to perform audio with a WebVTT transcript,
since the <audio> element doesn't allow captions using WebVTT.
To test the fallback content on browsers that support the element, you can replace <video> with a non-existing element like <notavideo> .
A good general source of information on using HTML <video> is the Video and audio content beginner's tutorial.
Styling with CSS
The <video> element is a replaced element — its display value is inline by default, but its default width and height in the viewport is defined
by the video being embedded.
There are no special considerations for styling <video> ; a common strategy is to give it a display value of block to make it easier to position,
size, etc., and then provide styling and layout information as required. Video player styling basics provides some useful styling techniques.
Detecting track addition and removal
You can detect when tracks are added to and removed from a <video> element using the addtrack and removetrack events. However, these
events aren't sent directly to the <video> element itself. Instead, they're sent to the track list object within the <video> element's
HTMLMediaElement that corresponds to the type of track that was added to the element:
HTMLMediaElement.audioTracks
An AudioTrackList containing all of the media element's audio tracks. You can add a listener for addtrack to this object to be alerted when
new audio tracks are added to the element.
HTMLMediaElement.videoTracks
Add an addtrack listener to this VideoTrackList object to be informed when video tracks are added to the element.
HTMLMediaElement.textTracks
Add an addtrack event listener to this TextTrackList to be notified when new text tracks are added to the element.
For example, to detect when audio tracks are added to or removed from a <video> element, you can use code like this:
JS
const elem = document.querySelector("video");
elem.audioTracks.onaddtrack = (event) => {
trackEditor.addTrack(event.track);
};
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video
5/11
02/04/2024, 07:54
<video>: The Video Embed element - HTML: HyperText Markup Language | MDN
elem.audioTracks.onremovetrack = (event) => {
trackEditor.removeTrack(event.track);
};
This code watches for audio tracks to be added to and removed from the element, and calls a hypothetical function on a track editor to
register and remove the track from the editor's list of available tracks.
You can also use addEventListener() to listen for the addtrack and removetrack events.
Server support for video
If the MIME type for the video is not set correctly on the server, the video may not show or show a gray box containing an X (if JavaScript is
enabled).
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.

First Ogg is tried. If that can't be played, then AVI is tried. Finally, MP4 is tried. A fallback message is displayed if the video element isn't
supported, but not if all sources fail.
Some media file types let you provide more specific information using the codecs parameter as part of the file's type string. A relatively simple
example is video/webm; codecs="vp8, vorbis" , which says that the file is a WebM video using VP8 for its video and Vorbis for audio.
Accessibility concerns
Videos should provide both captions and transcripts that accurately describe its content (see Adding captions and subtitles to HTML video for
more information on how to implement these). Captions allow people who are experiencing hearing loss to understand a video's audio content
as the video is being played, while transcripts allow people who need additional time to be able to review audio content at a pace and format
that is comfortable for them.
It's worth noting that while you can caption audio-only media, you can only do so when playing audio in a <video> element, since the video
region of the element is used to present the captions. This is one of the special scenarios in which it's useful to play audio in a video element.
If automatic captioning services are used, it is important to review the generated content to ensure it accurately represents the source video.
In addition to spoken dialog, subtitles and transcripts should also identify music and sound effects that communicate important information.
This includes emotion and tone:

15
00:03:19 --> 00:03:21
