If you want to make your media to play in Chromium browser, please read this document
For more information about how to set up a server to serve media properly and other general and useful topics about dealing with HTML5 video, this article is a good start point.
Do not compress media (mod_deflate or gzip), since it can lead to unexpected results, like headers not being passed correctly.
To get the default installation there are several different ways.
-
Download the package from https://github.com/mediaelement/mediaelement
-
Use a CDN reference; the most popular ones are jsDelivr and cdnjs.
-
Through GIT:
git clone https://github.com/mediaelement/mediaelement.git -
Through npm:
npm install mediaelement -
Through BOWER:
bower install mediaelement -
If you are using Meteor:
meteor add johndyer:mediaelementormeteor npm install mediaelement
WordPress currently incorporates MediaElementJS as a part of the Embeds core package. If you are using a version prior 4.9, and you want to upgrade MediaElementJS to the latest version, follow these steps:
- Find the block
if ( ! wp_is_mobile() ) {
wp_enqueue_style( 'wp-mediaelement' );
and add below the following:
wp_enqueue_script( 'mediaelement-vimeo' );
- Find the block
wp_localize_script( 'mediaelement', '_wpmejsSettings',
and add in the _wpmejsSettings the following:
'pauseOtherPlayers' => '',
'classPrefix' => 'mejs-',
'stretching' => 'responsive',
- Find the blocks that contain:
wp_print_scripts( 'wp-mediaelement' );
and replace them with:
wp_print_scripts( array( 'mediaelement-vimeo', 'wp-mediaelement' ) );
- Find the block that contains:
$library = apply_filters( 'wp_video_shortcode_library', 'mediaelement' );
if ( 'mediaelement' === $library && did_action( 'init' ) ) {
wp_enqueue_style( 'wp-mediaelement' );
wp_enqueue_script( 'wp-mediaelement' );
}
and replace it with:
$library = apply_filters( 'wp_video_shortcode_library', 'mediaelement' );
if ( 'mediaelement' === $library && did_action( 'init' ) ) {
wp_enqueue_style( 'wp-mediaelement' );
wp_enqueue_script( 'mediaelement-vimeo' );
wp_enqueue_script( 'wp-mediaelement' );
}
- Find the block that contains:
if ( $is_vimeo ) {
wp_enqueue_script( 'froogaloop' );
}
and replace it with:
if ( $is_vimeo ) {
wp_enqueue_script( 'mediaelement-vimeo' );
}
- Inside the function
wpview_media_sandbox_styles(), replace:
$mediaelement = includes_url( "js/mediaelement/mediaelementplayer.min.css?$version" );
with:
$mediaelement = includes_url( "js/mediaelement/mediaelementplayer-legacy.min.css?$version" );
- Remove all the files from the folder and install all the files inside the
buildfolder from theMediaElementproject. - Download and copy/paste the WordPress files contained in this link.
- Find the block:
$scripts->add( 'mediaelement', "/wp-includes/js/mediaelement/mediaelement-and-player.min.js", array('jquery'), '2.22.0', 1 );
and replace all of that until you reach the end of the translations, with this:
$scripts->add( 'mediaelement', "/wp-includes/js/mediaelement/mediaelement-and-player.min.js", array('jquery'), 'X.X.X', 1 );
did_action( 'init' ) && $scripts->localize( 'mediaelement', 'mejsL10n', array(

With Drupal, you can create your own module and add MediaElement to it (see this document for more information).
However, if you are using, or if you have a Drupal 7 installation and want to use, MediaElement Module, you have to update it performing the following steps:
-
Install the Libraries module, if you haven't.
-
Install the module into the
modulesfolder, if you haven't. -
Replace the line in the
modules/mediaelement/mediaelement.admin.incfile
'#markup' => '<video width="360" height="203" id="player1" src="' . $path . '/media/echo-hereweare.mp4"><p>Your browser leaves much to be desired.</p></video>',
with
'#markup' => '<video width="360" height="203" id="player1" src="https://media.w3.org/2010/05/sintel/trailer.mp4"></video>',
-
Install
MediaElementlatestbuildfolder into Drupal'ssites/all/libraries/mediaelementdirectory. -
Activate the module and configure it from Drupal's
Modulesection. -
Check the box on
Enable MediaElement.js site wide. -
Now every time you create a page/post and include the
videooraudiotag, the player will render them.
If you want to install any of them, refer to the new plugins repository clicking here for more information.
<script src="/path/to/jquery.js"></script>
<script src="/path/to/mediaelement-and-player.min.js"></script>
<!-- Add any other renderers you need; see Use Renderers for more information -->
<link rel="stylesheet" href="/path/to/mediaelementplayer.min.css" />If you wish to install the sources in different directories (i.e., all JavaScript files in a js, all CSS in a styles etc.), add the following CSS update after the mediaelementplayer.css reference (only if the images are not in the same folder as the stylesheet):
<link rel="stylesheet" href="/path/to/mediaelementplayer.min.css" />
<style>
.mejs__overlay-button {
background-image: url("/path/to/mejs-controls.svg");
}
.mejs__overlay-loading-bg-img {
background-image: url("/path/to/mejs-controls.svg");
}
.mejs__button > button {
background-image: url("/path/to/mejs-controls.svg");
}
</style>Check the content of mediaelementplayer.min.css (or if you decided to use the old styles, mediaelementplayer-legacy.min.css) to customize any CSS related to the player.
Also, as an example, visit this section to have an idea on how can you customize the look-and-feel of the player.
If your users have JavaScript the easiest route for all browsers and mobile devices is to use a single file.
<video src="myvideo.mp4" width="320" height="240" type="video/mp4"></video>or
<video width="320" height="240">
<source type="video/mp4" src="myvideo.mp4" />
</video>All the formats supported are listed in this table. Besides that, there are some additional attributes that can be added in the video/audio tag.
Visit the Attributes section for more information.
Note: Although it is important to include their MIME type so the plugin renders the media accurately, some browsers like Firefox can display warnings in regards of unknown/custom MIME types. But they do not prevent the plugin to work properly.
This includes multiple codecs for various browsers (H.264 for IE9+, Safari, and Chrome, WebM for Firefox 4 and Opera, Ogg for Firefox 3).
<video width="320" height="240" poster="poster.jpg" controls="controls" preload="none">
<source type="video/mp4" src="myvideo.mp4" />
<source type="video/webm" src="myvideo.webm" />
<source type="video/ogg" src="myvideo.ogv" />
</video>The way to setup closed captioning is by using the track tag as follows:
<video width="320" height="240" poster="poster.jpg" controls="controls" preload="none">
<source type="video/mp4" src="myvideo.mp4" />
...
<track src="subtitles_en.[srt|vtt]" kind="[subtitles|captions|chapters]" srclang="en" label="English">
<track src="subtitles_es.[srt|vtt]" kind="[subtitles|captions|chapters]" srclang="es" label="Spanish">
...
</video>This works perfectly on any browser that supports HTML5 natively; however, to make this work across browsers, an AJAX request is performed to parse the content of the subtitles file.
That's why is important to put the caption files in the same domain as the player is. Otherwise, the request of the file will be denied.
As a final note, to display closed captioning in iOS, they will need to be transcoded it in the video. To learn more about this topic, please read The Zencoder guide to closed captioning for web, mobile, and connected TV.
The easiest way to use the player is adding the class="mejs__player" to any <video>, <audio>, or <iframe> tags, and add the data-mejsoptions to configure it.
For more details and ways to set the player, please read the Usage section.
By default, all the strings in MediaElementJS are in English. If you wanna set a different language for them, you need to set the language code via mejs.i18n.locale.language before the player instantiation, and specify the language in the media container in the success callback.
Optionally, just can set the attribute lang in the <html> tag with the one you set before, to declare the default language of the text in the rest of the page as well.
<script>
mejs.i18n.language('de'); // Setting German language
$('audio,video').mediaelementplayer({
success: function(player, node) {
// Optional
$(player).closest('.mejs__container').attr('lang', mejs.i18n.language());
$('html').attr('lang', mejs.i18n.language());
// More code
}
});
</script>Available languages:
- Catalan (ca)
- Czech (cs)
- German (de)
- English (en)
- Spanish; Castilian (es)
- French (fr)
- Hungarian (hu)
- Italian (it)
