Filter for changing MediaElement.js Settings

3 Views

I am trying to change some of the settings that get loaded with MediaElement.js. I can’t seem to find a filter or hook to alter the settings that are loaded. The only way I was able to customize the settings is by opening up the core MediaElement.js file and changing the settings there.

Obviously this is less than ideal, because I’m forced to edit a core WordPress file which will be overridden on update. How can I change the settings using a filter so my settings aren’t lost?

  1. Copy wp-includes/js/mediaelement/wp-mediaelement.js into your theme or plugin and make your modifications there. For example, I added some settings to force the use of native video controls on iOS & Android devices, like so:

    (function ($) {
        // add mime-type aliases to MediaElement plugin support
        mejs.plugins.silverlight[0].types.push('video/x-ms-wmv');
        mejs.plugins.silverlight[0].types.push('audio/x-ms-wma');

        $(function () {
                var settings = {
                        // Put your custom MediaElement.js Player Options here...

                        alwaysShowControls: true,
                        // force iPad's native controls
                        iPadUseNativeControls: true,
                        // force iPhone's native controls
                        iPhoneUseNativeControls: true,
                        // force Android's native controls
                        AndroidUseNativeControls: true
                };

                if ( typeof _wpmejsSettings !== 'undefined' )
                        settings.pluginPath = _wpmejsSettings.pluginPath;

                $('.wp-audio-shortcode, .wp-video-shortcode').mediaelementplayer( settings );
        });

}(jQuery));

    You can then use an action to dequeue the original and enqueue your modified version. If you’re doing this in a theme, add the following to your functions.php file:

    add_action( 'wp_enqueue_scripts', 'my_mediaelement_settings' );
function my_mediaelement_settings() {
        wp_deregister_script( 'wp-mediaelement' );
        wp_register_script( 'wp-mediaelement', get_stylesheet_directory_uri() . "/js/wp-mediaelement.js", array( 'mediaelement' ), false, true );
}

    This assumes you put your modified wp-mediaelement.js file inside a js directory within your theme.

  2. Since WordPress 4.4 there actually is the filter mejs_settings, which does exactly what you want.

    In your case:

    add_filter('mejs_settings', function ($settings) {
    $settings['enableKeyboard'] = true;
    return $settings;
});

    If anyone is interested, it works like this: wp-includes/script-loader.php turns this into an inline <script> in the <head> that sets a global JS object _wpmejsSettings, which, on domReady, is passed to the .mediaelementplayer() function in wp-includes/js/mediaelement/wp-mediaelement.js.
