HTML 5 supports
<video> tag also. The HTML video tag is used to add video files on the web page. The HTML5
<video> element specifies a standard way to embed a video in a web page.
The HTML 5 <video> tag accepts attributes that specify how the video should be played.
Before HTML5 In HTML4 and earlier versions, video files could only be added to websites using various
multimedia plugins (e.g., Adobe Flash).
The <video> tag was introduced in HTML 5 (officially referred to as HTML5 - without the space). HTML5 video is now widely implemented
in the major browsers and it has support from major websites such as YouTube.
HTML5 has a
native video element that supports three video formats
(MP4, WebM and Ogg),
making it much easier to embed videos in a webpage.
You can define the external source for the video using a
file or a
type attribute defines the format of the video file used.
controls attribute adds video controls, like play, pause, and volume.
It is a good idea to always include
If height and width are not set, the page might flicker while the video loads.
<source> element allows you to specify alternative video files which the browser may choose from.
The browser will use the first recognized format.
It is always recommended to add
HTML5 video controls to your player. Using special buttons
in the player window, the user can manually start and stop the video, skip to specific place using the slider,
or toggle between window and full screen video display, control volume. To add video controls, include the controls attribute:
To define the size of your player, you can use the
The video will keep the same aspect ratio.
If the video cannot be played in any format provided, the user will see the text known as the
fallback content. It is the only content within the
<video> tags. Use it to provide information to the user or a direct link to the video file.
HTML 5 Support Attributes like preload, autoplay, loop and more. It is also mandatory to define the source for the video. You can do it by using a simple
src attribute, but it is recommended to choose the
<source> tags for that:
The reason this is considered a better practice is because using the
<source> tags allows you to define
multiple sources. The HTML5 video player supports three formats (.mp4, .ogg and .webM), but not all of them have the same level of browser support. This means you can add sources in different formats to ensure the user can see the video.
The source element lets you specify multiple formats as a
fallback in case the user's browser doesn't support one of them. For example:
When the browser parses the
<source> tag, it uses the optional type attribute to help decide which file to download and play. If the browser supports WebM and has the VP8 and Vorbis codecs, it will play devstories.webm, if not, it will check if it can play MPEG-4 videos with the avc1.42E01E and mp4a.40.2 codecs, and so forth.
Note: To improve performance, you should always include the type attribute in the source element. Otherwise the browser will need to load each video file until it can find one that it can play!
Adding a media fragment to the media URL, you can specify the exact portion you want to play. To add a media fragment, you simply add
#t=[start_time][,end_time] to the media URL. For example, to play the video between seconds 10 through 20, you could specify:
You can also specify the times in hours:minutes:seconds, such as
#t=00:01:05 to start the video at one minute, five seconds in. Or, to only play the first minute of the video, you would specify
#t=,00:01:00. You need to make sure Range Requests are supported by your server: check for Accept Ranges: bytes. It's on by default for Apache and many other servers, but worth checking.
|Video File Format||Media Type|
HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".
The attributes that you can add to this tag are listed below.
|height||It is used to set the height of the video player.
Specifies the height, in pixels, to display the video.
|width||It is used to set the width of the video player.
Specifies the width, in pixels, to display the video.
|poster||Poster specifies the image which will work as a thumbnail until the video is loaded completely on the webpage. Just specify the address of the image you want to use as poster.|
|autoplay||It specifies that the video will start playing as soon as it is ready.
Specifies whether or not to start playing the video as soon as it can do so without stopping.
This attribute is a boolean attribute. Therefore, the mere presence of this attribute equates to a true value. You can also specify a value that is a case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either autoplay or autoplay="autoplay").
For synchronizing playback of videos (or media elements). Allows you to specify media elements to link together. The value is a string of text, for example: mediagroup=movie. Videos/media elements with the same value are automatically linked by the user agent/browser.
An example of where the mediagroup attribute could be used is where you need to overlay a sign-languge interpreter track from one movie file over the top of another.
Specifies whether or not to display video controls (such as a play/pause button etc). This attribute is a boolean attribute. Therefore, the mere presence of this attribute equates to a true value. You can also specify a value that is a case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either controls or controls="controls").
It is used to play the video on loop i.e., video will start over again every time from the start when it is completed. Just add this as an attribute without any value it will still work. You can also use it like this
|preload||It specifies the author view to upload video file when the page loads. It is ignored if
Note that the autoplay attribute can overrride the preload attribute (since if the media plays, it naturally has to buffer first, regardless of the hint given by the preload attribute). Despite this, you can still provide both attributes.
Controls the default state of the video's audio output. If present, this attribute results in the audio output being muted (i.e. there is no sound) upon loading. This attribute will override the users' preferences. The user can then choose to turn on the sound if he/she so wishes. This helps users from being annoyed by loud sounds coming from the video as soon as the page/video starts loading. Users often close their browser when this happens. The 'mute' attribute aims to overcome this issue by having the video start off silently instead of loudly.This attribute is a boolean attribute. Therefore, the mere presence of this attribute equates to a true value. You can also specify a value that is a case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either muted or muted="muted").
|src||It specifies the source URL of the video file.|
video tag accepts the following global attributes. These attributes are standard across all HTML 5 tags.
|accesskey||Specifies a shortcut key that can be used to access this
[Any string of characters. This string of characters specifies the key/s the user needs to use in order to access the element.]
|class||This is a document wide identifier. It is used to refer to a class that is specified in the style sheet. The value should match the name of the class you wish to use.|
|contenteditable||This attribute specifies whether the user can edit the content or not.
|dir||Specifies the direction of the text.
|draggable||It enables the user to drag the
Its possible values are:
Must be an unordered set of unique space-separated tokens that are ASCII case-insensitive.
Note that this attribute must not have more than one of the three feedback values (copy, move, and link) specified. If none are specified, the copy value is implied.
|hidden||The hidden attribute as the name suggests is used to hide nay element. You can use this element with
|itemprop||This attribute provides one or more properties to one or more "items".
Although this attribute is optional, if used it must have a value that is an unordered set of unique space-separated tokens that are case-sensitive, representing the names of the name-value pairs that it adds. The attribute's value must have at least one token. Each token must be one of the following:
|itemref||This attribute is used in conjunction with the
|itemscope||HTML5 elements that have the
This is a boolean attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either
|itemtype||This attribute provides an item type for elements containing the
|lang||Sets the language code to be used.
[Must be a valid RFC 3066 language code, or an empty string.]
|spellcheck||Specifies whether the element should have its spelling checked.
If this attribute is missing, the element will use the default behavior, possibly based on the parent's own
|style||Specifies inline styles for this
|tabindex||Helps determine the tabbing order for this
[Any valid integer. For example, 0, 1, 2, 3, ...etc]
|title||It specifies a title to the
|translate||Determines whether the element's attribute values and the values of its Text node children are to be translated when the page is localized, or whether to leave them unchanged.
Event handler content attributes enable you to invoke a script from within your HTML.
The script is invoked when a certain
"event" occurs. Each event handler content attribute deals with
a different event.
Here are the standard HTML 5 event handler content attributes.

|onblur||User has left the focus of the element.|
|oncanplay||Invoked when the browser/user agent can start playing media, but hasn't yet, due to buffering. In other words, if playback were to begin now, it wouldn't play right to the end (due to the current playback rate) - it would need to pause during playback in order to load the rest of the media.|
|oncanplaythrough||The browser/user agent estimates that if playback were to begin now, the media resource could be rendered at the current playback rate all the way to its end without having to stop for further buffering.|
