The WikiVideos extension allows the creation of videos using wikitext.

Usage

The following wikitext:

<gallery mode="video" width="300">
File:Old pond.jpg | Old pond
File:Frog leap.jpg | frog leaps in
File:Water sound.jpg | water's sound
</gallery>

will output the following video:

Essentially, the algorithm shows one image after another while an automated voice reads the text aloud.

Installation

Setup your Google Text-to-Speech API
Install the latest FFmpeg and FFprobe
Download and move the extracted WikiVideos folder to your extensions/ directory.
Developers and code contributors should install the extension from Git instead, using:cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/WikiVideos
Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See task T173141 for potential complications.)
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'WikiVideos' );
```
Configure as needed.
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Editing with the visual editor

Until this issue gets fixed, to edit videos with the visual editor, you'll need to manually add the following to extensions/VisualEditor/modules/ve-mw/ui/dialogs/ve.ui.MWGalleryDialog.js, line 275:

new OO.ui.MenuOptionWidget( {
	data: 'video',
	label: 'Video'
} ),

Configuration

Each configuration option is shown with its default value:

Required

$wgGoogleCloudCredentials = ''; ― Absolute path to the application credentials for your Google service account.
$wgFFmpegLocation = '/usr/bin/ffmpeg'; ― Absolute path to FFmpeg (see $wgFFmpegLocation).
$wgFFprobeLocation = '/usr/bin/ffprobe'; ― Absolute path to FFprobe (see $wgFFprobeLocation).

Optional

$wgWikiVideosUserAgent = 'WikiVideos/4 (https://www.mediawiki.org/wiki/Extension:WikiVideos)'; ― Content of the User-Agent header when downloading files from Commons. Required to comply with Wikimedias User-Agent policy.
$wgWikiVideosMinSize = 200; ― Default min size of the video files.
$wgWikiVideosMaxSize = 1280; ― Default max size of the video files. If the video width is larger than the height, then this limits the width, while the height is scaled accordingly, and viceversa if the height is larger than the width.
$wgWikiVideosControls = true; ― Whether to show video controls by default (play/pause button, volume, etc).
$wgWikiVideosAutoplay = false; ― Whether to autoplay videos by default.
$wgWikiVideosChapters = true; ― Whether to show video chapters by default.
$wgWikiVideosCaptions = false; ― Whether to show video captions by default.
$wgWikiVideosVoiceLanguage = ''; ― Preferred voice language (see supported voices and languages). If left empty, the main language of the wiki will be used (see $wgLanguageCode). May be overridden on a per-video basis using the voice-language attribute (for example <gallery voice-language="es">), optionally specifying a supported locale (for example <gallery voice-language="en-GB">).
$wgWikiVideosVoiceGender = ''; ― Preferred voice gender (either male or female). If left empty, the gender of the first voice for the chosen language will be used (see supported voices and languages). May be overridden on a per-video basis using the voice-gender attribute (for example <gallery voice-gender="female">).
$wgWikiVideosVoiceName = ''; ― Preferred voice name (see supported voices and languages). If left empty, the first voice for the chosen language and gender will be used. May be overridden on a per-video basis using the voice-name attribute (for example <gallery voice-name="es-ES-Standard-B">).
