Why?

The player that Wikimedia used since 2010 has several significant downsides, which were limiting us in making further improvements.

It does not work correctly on mobile devices, which are the majority of our readers now.
Not widely used by others.
Written before HTML5 video was standardised.
Uses its own subtitling system.
Written to be compatible with Internet Explorer 6 and used the JavaScript standards of those times.
Written before our own JavaScript stack was developed.
Had been virtually unmaintained since 2011.

Known issues

When a wiki is being switched, for several days you might notice that some pages will show the old player and other pages the new player. This is expected and caused by caching. No action or bug report is required for this.
Subtitles may fail on some files. We dropped support for wikicode markup inside of the subtitles. You are advised to rewrite these subtitles (T224258).
Audio opens a dialog rather than displayed inline when there is a transcription. This is a deliberate change, that will in future allow us to display transcriptions for audio. Please see phab:T246035.

The video player is still in development, but if you find any problems, please report these on the talk page or file them in Phabricator.

Developers

Developers working on features that use the Video.js player will need to initialize and configure it appropriately. Below is an example of typical usage.

Basic Configuration Example

This is outdated and should be reworked to make use of our player wrappers, which apply consistent options and settings for videojs playback.

// The first argument can be a string ID or a <video> element
var player = videojs( 'my-player-id', {
    controls: true,
    autoplay: false,
    poster: "https://path/to/poster/image"
    sources: [ /* array of source files in various sizes and formats */ ]
} );

The sources can also be provided in the HTML ‎<video> element instead of in JS:

<video class="video-js">
  <source src="//vjs.zencdn.net/v/oceans.mp4" type="video/mp4">
  <source src="//vjs.zencdn.net/v/oceans.webm" type="video/webm">
</video>

Advanced configuration with Ogv.js support

If you need cross-platform playback of OGG or WebM files (many files in Commons are in these formats), you can use the Ogv.js plugin for Video.js, which is also included in TimedMediaHandler. Example configuration:

var player;

// Load the appropriate modules in ResourceLoader
mw.loader.using( 'ext.tmh.videojs-ogvjs' ).then( function () {
    // Load ogvjs if necessary; when this promise resolves,
    // all necessary code has been loaded
    return mw.OgvJsSupport.loadIfNeeded();
} ).then( function () {
    player = videojs( 'my-player-id', {
        controls: true,
        autoplay: false,
        poster: 'https://path/to/my/image',
        sources: [ /* array of sources */ ],
        
        // Ogv.js-specific configuration
        ogvjs: {
            base: mw.OgvJsSupport.basePath()
        }
    } );
} );
