Video is an extension that allows you to import videos from different video services, such as YouTube, DailyMotion or Metacafe. The extension adds two new special pages, Special:AddVideo, which all registered users or other users with 'addvideo' permission can access to add new videos to the site and Special:NewVideos, which lists all recently added videos. The extension also adds <videogallerypopulate> parser hook tag.

Video additions are logged into the video log at Special:Log/video.

This extension was originally written by David Pean for Wikia, Inc. Some code cleanup was done by Łukasz 'TOR' Garczewski and Bartek Łapiński for Wikia, Inc. and by Jack Phoenix for ShoutWiki.

Installation

• Download and place the file(s) in a directory called Video in your extensions/ folder.

• Add the following code at the bottom of your LocalSettings.php:

  wfLoadExtension( 'Video' );
  

• Run the update script which will automatically create the necessary database tables that this extension needs.
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Usage

After adding a video through Special:AddVideo, you can embed it into an article by using the syntax [[Video:Video's Name Here]] or <video name="Video's Name Here"/>.

To-do list/known bugs

1. Write the code for supporting 5min.com, Nicovideo and Tangler.com
2. If a video is embeded in a page and this page is later transcluded, it only shows a link to Video:foo and not the embeded video.

Developer Info

Provider classes for different video hosting sites are stored in the providers directory. Writing a new provider class is easy:

1. copy the example provider class into the providers directory and name it accordingly (for example, ExampleVideo.php)
2. autoload the new provider class in Video.php
3. add the provider to Video::$providers
4. enjoy!

Example provider class

<?php

class ExampleVideoProvider extends BaseVideoProvider {
	// Used to extract the $video_id from the URL
	protected $videoIdRegex = '#/watch/([a-zA-Z0-9_\-]+)/#';
	// Set this to the embed, and use $width, $height and $video_id appropriately
	protected $embedTemplate = '<object width="$width" height="$height"><param name="movie" value="$video_id">...etc';

	/**
	 * Gives all domains that this provider should respond to
	 *
	 * Second level domains are preferred
	 *
	 * @return array
	 */
	public static function getDomains() {
		return array( 'example.com' );
	}

	/**
	 * Return the aspect ratio for the video player
	 *
	 * Just what the player is set to by default: Width / Height
	 *
	 * @return float
	 */
	protected function getRatio() {
		return 512 / 296;
	}

	/**
	 * If there is more complexity to retrieving the $video_id for the embed
	 * code than a single regular expression, override this function.
	 * 
	 * If you make an HTTP call (eg. to an API) you MUST cache it with $wgMemc
	 * 
	 * @param string $url URL to extract the ID from
	 * @return bool|null|Object
	 */
	/*
	protected function extractVideoId( $url ) {
		// Check out HuluVideoProvider or Viddler for an example
	}
	*/
	
	/**
	 * Override this function for cases where the HTML embed code is complex
	 * and has special cases.
	 * 
	 * @return string Raw HTML to display the video
	 */
	/*
	public function getEmbedCode() {
		return '...';
	}
	*/
