The EmbedVideo extension adds a parser function called #ev for embedding video clips from over 24 popular video sharing services in multiple languages and countries. It also adds video and audio media handlers to support transforming standard [[File:Example.mp4]] file links into embedded HTML5 <video> and <audio> tags.

Notice: As of the 2.x series the EmbedVideo extension has a new maintainer and an entirely rewritten code base. It retains backwards compatibility with EmbedVideo 1.0 and EmbedVideoPlus.


Media handler[edit]

For locally uploaded content the process for displaying it on a page is the same as an image. See the image syntax documentation on MediaWiki.org for complete reference on this feature.

This example would display a video in page using a HTML5 <video> tag.


To specify the start and end timestamps in the media use the start and end parameters. The timestamp can be formatted as one of: ss, :ss, mm:ss, hh:mm:ss, or dd:hh:mm:ss.



The EmbedVideo parser function expects to be called in any of the following ways:

#ev - Classic parser tag[edit]

  • {{#ev:service|id}}
  • {{#ev:service|id|dimensions}}
  • {{#ev:service|id|dimensions|alignment}}
  • {{#ev:service|id|dimensions|alignment|description}}
  • {{#ev:service|id|dimensions|alignment|description|container}}
  • {{#ev:service|id|dimensions|alignment|description|container|urlargs}}
  • {{#ev:service|id|dimensions|alignment|description|container|urlargs|autoresize}}
  • {{#ev:service|id|dimensions|alignment|description|container|urlargs|autoresize|valignment}}

However, if needed optional arguments may be left blank by not putting anything between the pipes:

  • {{#ev:service|id|||description}}

#evt - Parser tag for templates[edit]

The #evt parser tag allows for key=value pairs which allows for easier templating and readability.


#evu - Parser tag for URLs[edit]

The #evu parser tag is like the #evt tag, but its first parameter is a URL that will be parsed to determine the service automatically.


<embedvideo> - Tag hook[edit]

Videos can easily be embedded with the <embedvideo></embedvideo> tag hook. The ID/URL goes as the input between the tags and parameters can be added as the tag arguments.

<embedvideo service="youtube">https://www.youtube.com/watch?v=StPSujfX0YI</embedvideo>

Alternativly, you can also use the service id as the tag (assuming another extension isn't already using this tag).


Attributes for parser tags[edit]

Attribute Description
service="(See Supported Services below.)" Required: yes
The video service to call.
id="[id|url]" Required: yes
The raw ID of the video or URL from the player page.
dimensions="[WIDTH|WIDTHxHEIGHT|xHEIGHT]" Required: no, Default: 640
Dimensions in pixels to size the embed container. The standard format is width x height where either can be omitted, but the x must proceed height to indicate it as the height.
Examples: 480, 480x320, x320. If the height is not provided it will be calculated automatically from the width and service default ratio.
Some services such as Gfycat do not have standard heights and should be specified for each embed. $wgEmbedVideoDefaultWidth can be set in LocalSettings.php to override the default width.
alignment="[left|center|right|inline]" Required: no, Default: none
Align the placement of the video either to the left, centered, or to the right. Inline will allow multiple videos to display side by side without forced line breaks.
description="[wiki text]" Required: no, Default: none
Display a description under the embed container. For line breaks use &#10; (see https://www.w3.org/TR/REC-xml/#AVNormalize)
container="[frame]" Required: no, Default: none
Specifies the container type to use for the embed.
frame: Wrap the video player in a Mediawiki thumbnail box.
urlargs="modestbranding=1&version=3" Required: no, Default: none
Allows extra URL arguments to be appended to the generated embed URL. This is useful for obscure options only supported on one service.
autoresize="false" Required: no, Default: true
Automatically resize videos when their size will cause them to break outside of their container element.
valignment="[top|middle|bottom|baseline]" Required: no, Default: none
Align the vertical placement of the video either to the top, middle, bottom, or baseline of the parent element. Using this parameter forces the alignment parameter to be inline.


Example #1

For example, a video from YouTube uses the 'youtube' service selector. You can specify either the raw ID:


Or specify the full URL:


To display the same video as a right aligned large thumbnail with a description:

{{#ev:youtube|https://www.youtube.com/watch?v=StPSujfX0YI|1000|right|Let eet GO|frame}}

For YouTube to have the video start at a specific time code utilize the urlargs(URL arguments) parameter. Take the rest of the URL arguments from the custom URL and place them into the urlargs. Please note that not all video services support extra URL arguments or may have different keys for their URL arguments.


URL arguments can be used to chop up a video and loop it:


Support for VideoLink tags[edit]

Support for the unmaintained VideoLink extension’s tags has been added since version 2.5.

From the original extension documentation:

The VideoLink extension allows embedding of YouTube videos in articles; allowing for multiple linked videos to be played in a single embedded video player, first shown when a user clicks on a video link.

The <evlplayer /> specifies where the player should appear within the page, and the {{#vlink}} parser function allows creation of links that load a specific video.

<evlplayer> - Tag hook for video container[edit]

Note that the use of the <vplayer> tag is also acceptable here for backwards compatibility.

This evlplayer tag is used to position the video player container within the page.

<evlplayer id="player id" w="width" h="height" class="class" style="style">default content</evlplayer>

A default video can be set to fill the container by default instead of default content as well.

<evlplayer id="player1" w="480" h="360" service="youtube" defaultid="StPSujfX0YI" />
Attributes Required Default Description
id no default An optional unique identifier for this container
w no 800 Width to send to the embedded player when its generated
h no achieve 16:9 from width Height to send to the embedded player when its generated
class no Additional CSS class to add to the container div
style no Additional in-line CSS to apply to the container div
defaultid no Video ID of default video, if you want a default video.
service no Service of default video, if you want a default video.

An important caveat to make note of, is that the w and h attributes only effect the video that is being included into the container div, and not the actual container. For styling of the container, please use the class or style attributes.

#evl - Parser function for video links[edit]

Note that the use of the {{#vlink}} parser function is also acceptable here for backwards compatibility.

{{#evl:<video id>|<Link text>>|<video to play>|service=youtube|player=<player id>}}

In addition to all of the attributes supported by the #evt tag, these specific attributes apply to the #evl (and #vlink) tags. To maintain backwards compatibility, if you do not define a service then youtube is assumed.

Attributes Required Default Description
video id yes none The ID of the video you would like to play or a comma separated list of videos to play. Please note that the use of multiple video IDs separated by a semicolon is now deprecated.
link text yes none The text to display inside the link
video to play no none The number that represents the video to play from video id if its is a comma separated list of ids.
player no ‘default’ Player container to load video in. Note that the ID ‘default’ will only exist if you’ve defined a player with no ID.
initial video deprecated In the original VideoLink, this would define what video to play first if multiple videos were define. Please see notes about in video id and start.
start deprecated 0:00 In the original VideoLink, this defined the start time of a video. Since we support multiple video services, this feature can now be replicated with the urlargs parameter. For backwards compatibility, this attribute will be respect on videos with the service youtube.

Video link examples[edit]

Creating a video list allows video links to create a playlist on the fly using the youtube and youtubevideolist service. Note: even if you define a service the system will use youtube if a list of videos is provided.

<evlplayer w="width" h="height" class="class" style="style" id="example-player">default content</evlplayer>
{{#evl:21X5lGlDOfg|NASA Live|1|player=example-player}}
{{#evl:lEyCq2KRZik|IIS Q&A|2|player=example-player}}
{{#evl:OLeWbRdW6rY|Space Station Tour|3|player=example-player}}

Developer notes[edit]

The major benefit of using a parser function as the injection mechanism for video clips (as opposed to an extension tag) is that parser functions can utilize template parameters (of the form {{{1}}}).

For example, say you found yourself making a lot of YouTube videos in thumbnail size, right-aligned like an image. You might make a template called Template:Youtube_tn which could contain this:

<div class="thumb tright">

And then call it like this:

{{youtube tn|someYoutubeId}}
