The EmbedVideo Extension is a MediaWiki extension which adds a parser function called #ev for embedding video clips from over 22 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.

The original version of EmbedVideo was created by Jim R. Wilson. That version was later forked by Mohammed Derakhshani as the EmbedVideoPlus extension. In early 2010 Andrew Whitworth took over active maintenance of both extensions and merged them together as "EmbedVideo". Much later on in September 2014 Alexia E. Smith forcefully took over being unable to contact a current maintainer.
The newer versions of EmbedVideo are intended to be fully backwards-compatible with both older EmbedVideo and EmbedVideoPlus extensions.

There are three places to download the EmbedVideo extension. The first is directly from its GitHub project page, where active development takes place. If you have git, you can use this incantation to check out a read-only copy of the extension source:
git clone https://github.com/HydraWiki/mediawiki-embedvideo.git
Downloadable archive packages for numbered releases will also be available from the github project page.
- Download the contents of the extension, as outlined above.
- Create an EmbedVideo folder in the extensions/ folder of your MediaWiki installation.
- Copy the contents of this distribution into that folder
For Mediawiki 1.19 through 1.23 add the following line to your LocalSettings.php:
require_once("$IP/extensions/EmbedVideo/EmbedVideo.php");
For Mediawiki 1.24 and up add the following line to your LocalSettings.php:
wfLoadExtension("EmbedVideo");
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.
[[File:Example.mp4]]
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.
[[File:Example.mp4|start=2|end=6]]
The EmbedVideo parser function expects to be called in any of the following ways:
{{#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}}
However, if needed optional arguments may be left blank by not putting anything between the pipes:
{{#ev:service|id|||description}}
The #evt parser tag allows for key=value pairs which allows for easier templating and readability.
{{#evt:
service=youtube
|id=https://www.youtube.com/watch?v=pSsYTj9kCHE
|alignment=right
}}
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.
{{#evu:https://www.youtube.com/watch?v=pSsYTj9kCHE
|alignment=right
}}
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=pSsYTj9kCHE</embedvideo>
Alternativly, you can also use the service id as the tag (assuming another extension isn't already using this tag).
<youtube>https://www.youtube.com/watch?v=pSsYTj9kCHE</youtube>
Attribute | Required | Default | Description |
---|---|---|---|
service="(See Supported Services below.)" |
yes | The video service to call. | |
id="[id|url]" |
yes | The raw ID of the video or URL from the player page. | |
dimensions="[WIDTH|WIDTHxHEIGHT|xHEIGHT]" |
no | 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]" |
no | 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]" |
no | none | Display a description under the embed container. |
container="[frame]" |
no | 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" |
no | 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" |
no | true | Automatically resize videos when their size will cause them to break outside of their container element |
valignment="[top|middle|bottom|baseline]" |
no | 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. |
For example, a video from YouTube use the 'youtube' service selector enter either the raw ID:
{{#ev:youtube|pSsYTj9kCHE}}
Or the full URL:
{{#ev:youtube|https://www.youtube.com/watch?v=pSsYTj9kCHE}}
To display the same video as a right aligned large thumbnail with a description:
{{#ev:youtube|https://www.youtube.com/watch?v=pSsYTj9kCHE|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.
https://www.youtube.com/watch?v=pSsYTj9kCHE&start=76
{{#ev:youtube|https://www.youtube.com/watch?v=pSsYTj9kCHE|||||start=76}}
Creating a video list for Youtube. This allows you to queue a set of video in a temporary playlist. Use the 'youtubevideolist` service selector:
{{#ev:youtubevideolist|-D--GWwca0g|||||playlist=afpRzcAAZVM,gMEHZPZTAVc,lom_plwy9iA,BSWYMQEQhEo,EREaWhXj4_Q}}
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 <vplayer /> specifies where the player should appear within the page, and the {{#vlink}} parser function allows creation of links that load a specific video.
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="pSsYTj9kCHE" />
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.
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. Passing a comma separated list of video ids is only supported for the youtube
service.
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 . |
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 style="position:relative; width: 800px; margin: 0.5em 0" id="example-player">default content</evlplayer>
{{#evl:pSsYTj9kCHE,pSsYTj9kCHE,pSsYTj9kCHE|Play All|player=example-player}}
{{#evl:pSsYTj9kCHE,pSsYTj9kCHE,pSsYTj9kCHE|Let eet Go|1|player=example-player}}
{{#evl:pSsYTj9kCHE,pSsYTj9kCHE,pSsYTj9kCHE|Let eet Go|2|player=example-player}}
{{#evl:pSsYTj9kCHE,pSsYTj9kCHE,pSsYTj9kCHE|Let eet Go|3|player=example-player}}
As of version 2.x, EmbedVideo supports embedding video content from the following services:
