    Video.js Resolution Selector

    Add a resolution selector button to Video.js to allow users to manually adjust the video quality.


    You can use bower (bower install videojs-resolution-selector), npm (npm install videojs-resolution-selector), or simply download the source from this repo. You must be running Video.js 4.7.3 or higher for this plugin to function. You can download the latest source at the main Video.js repo, or you can get production files from, or you can use the CDN files.


    Add an extra attribute to your <source /> elements.

        <source data-res="480" src="..." type="..." />
        <source data-res="240" src="..." type="..." />

    Enable the plugin as described in the video.js docs. Optionally, you can pass some settings to the plugin:

    videojs( '#my-video', { plugins : { resolutionSelector : {
        force_types : [ 'video/mp4', 'video/webm' ],
        default_res : "480"
    } } } );

    force_types is an array. The plugin will check each resolution to make sure there is a source of each type at that resolution.

    default_res must be a string. You can either specify a single resolution or a comma separated list (e.g. "480,240"). When using a list, the first available resolution in the list will be selected by default.

    The plugin also triggers a changeRes event on the player instance anytime the resolution is changed, so your code can listen for that and take any desired action on resolution changes:

    videojs( '#my-video', { plugins : { resolutionSelector : {} } }, function() {
        var player = this;
        player.on( 'changeRes', function() {
            console.log( 'Current Res is: ' + player.getCurrentRes() );

    The plugin provides a changeRes method on the player object. You can call it like so (after your player is ready): player.changeRes( '480' ).

    Simple Example

    <!DOCTYPE html>
        <link href="//" rel="stylesheet" />
        <script src="//"></script> 
        <link href="video-quality-selector.css" rel="stylesheet" type="text/css" />
        <script src="video-quality-selector.js"></script> 
        <video id="example-2" class="video-js vjs-default-skin" controls width="640" height="360" data-setup='{ "plugins" : { "resolutionSelector" : { "default_res" : "480" } } }'>
            <source src="video-360.mp4" type="video/mp4" data-res="360" />
            <source src="video-480.mp4" type="video/mp4" data-res="480" />

    Please see example.html for a more advanced example.

    Styling the Button

    By default, the button will not be visible. You will either need to include the styles from video-quality-selector.css (after the default Video.js styles to override them), or use your own icon for the button. To match the rest of the Video.js controls, I recommend using an icon font to style the button, but it's up to you.

    Mobile devices

    If you want this plugin to work on mobile devices, you need to enable the video.js controls because the native controls are default on iOS and Android.

    <video data-setup='{"customControlsOnMobile": true}'>


    npm i videojs-resolution-selector
