The EmbedVideo Extension is a MediaWiki extension which adds a parser function called #ev and various parser tags like <youtube> for embedding video clips from various video sharing services.
It also adds video and audio media handlers to support transforming standard [[File:Example.mp4]] file links into embedded HTML5 <video> and <audio> tags.
This privacy enhanced fork adds a toggleable setting that only loads external content after the user gave explicit consent by clicking the video.
Do note that thumbnails are still fetched from the respective service, which results in a connection to an external url. This behaviour can be disabled by setting $wgEmbedVideoFetchExternalThumbnails to false.

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/StarCitizenWiki/mediawiki-extensions-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
- Install FFmpeg, when using the local video handler (enabled by default)
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]]
Additionally, a cover image can be set for video files by specifying a cover= key.
[[File:Example.mp4|start=2|end=6|poster=File:LocalFile.png]]
Example of a local file with a custom cover image.
The following options are available when using the media handler for local files.
Options are added to the wikitext like |poster=File:... or |start=2.
- loop
- Loops the audio / video
- autoplay
- Automatically plays the file
- nocontrols
- Disables the control elements
Options only available for video files:
- poster / cover
- Sets a local image file as the cover of the video
- muted
- Mutes the audio track of the video (required for autoplay)
- gif
- Special option that sets autoplay, muted, loop and nocontrols e.g. makes the video behave like a gif
When $wgEmbedVideoUseEmbedStyleForLocalVideos is enabled two additional options are available
- title
- Title of the video
- description
- Description shown below the video
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}}
However, if needed optional arguments may be left blank by not putting anything between the pipes:
{{#ev:service|id|||description}}
Alternatively each parameter can be used in any order as a named parameter. The following parameter are available:
iddimensionsalignmentdescriptioncontainerurlArgsautoresize- Set
|autoresize=trueto have the embed automatically use all available width of the parent element
- Set
vAlignmentwidthheightposter/cover- This only has an effect if
$wgEmbedVideoRequireConsentis set to true
- This only has an effect if
title- This only has an effect if
$wgEmbedVideoRequireConsentis set to true
- This only has an effect if
Do note mixing named and unnamed parameters will require you to add all unnamed parameters (and blanks) in the previously mentioned order.
E.g. using named id and unnamed description {{#ev:service||||This is the Description|id=abc}}/ {{#ev:service|id=abc|||This is the Description}}
The {{#evu}} parser function tries to extract the service from the host name of an url.
It takes the same arguments as {{#ev}}.
The support for {{#evl}} / {{#vlink}} and <evlplayer> / <vplayer> has been added with version 3.4.0.
The link parser function takes the following arguments:
id- Video IDtext- Link Textplayer- ID of the<evlplayer>if multiple exist on a pageservice- Name of the embed service, defaults to YouTube
Named arguments can be passed in any order, unnamed args must be passed in the order defined above.
The corresponding player that plays the videos defined by {{#evl}} links.
Note that this implementation differs from EmbedVideo v2.x in the following areas:
- No
default contentis supported, i.e. text inside the tags - A default video id should be defined, else the player displays a blank embed
- In the old implementation nothing was shown
- No
styleattribute can be set - Video lists are not supported
<evlplayer w="width" h="height" class="class" id="example-player" defaultid="pSsYTj9kCHE"></evlplayer>`
{{#evl:21X5lGlDOfg|NASA Live|player=example-player}}`
{{#evl:6ZFbXIJkuI1dVNWvzJzown|text=Spotify Track|service=spotifytrack|player=example-player}}Shows a YouTube embed for the video pSsYTj9kCHE and two video links, one for another YouTube video (NASA Live) and a Spotify track.
For more information on SharePoint embeds see Issue #60.
For example, a video from YouTube use the 'youtube' service selector enter 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|Example description|frame}}
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}}
Using the service name as a parser tag
<youtube>https://www.youtube.com/watch?v=eAORm-8b1Eg</youtube>
Using a local file as an embed thumbnail
{{#ev:youtube|pSsYTj9kCHE|poster=File:LocalFile.jpg}}
Using a local file as an embed thumbnail and specifying a title
{{#ev:youtube|pSsYTj9kCHE|poster=File:LocalFile.jpg|title=Title of the Embed}}
Using named parameters
{{#ev:youtube|id=pSsYTj9kCHE|dimensions=320x320}}
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}}
or
{{#ev:youtube|pSsYTj9kCHE|||||start=32}}
or
{{#ev:youtube|id=pSsYTj9kCHE|urlArgs=start=32}}
or
{{#ev:youtube|id=pSsYTj9kCHE|urlArgs=start=32&end=42}}
