Creating Kaltura player plugin to control KDP events

KDP events are a great way to control your Kaltura player. you can listen to events, trigger actions, and get information about the player.
Lately I’ve been working on a web page where the user can edit a video in an efficient manner using hotkeys. I found a nice plugin that does some of the functionality that i needed, but not all of it. After some investigation I discovered that the best way for me to achieve my goal, was to create a Kaltura Player plugin to control KDP events. That way i could inject custom functionality to control the player.

First thing that needed to be done was to add ‘myPlugin.js’ to the project and add the plugin to the flashvars:

playerConfig: {
            'widget': {
                'wid': '_101',
                'uiconf_id': '123456',
                 'entry_id': '0_123456',
                 'flashvars': {
                        'plugin': true,
                        'iframeHTML5Js' : 'js/myPlugin.js'

Next, I added functionality to the player through myPlugin.js. In this example, I’ve added the following functionality:
1. Pressing the left arrow will jump back in the video video by 10 seconds and the right arrow will jump forward.
2. Alert the user when the video has ended.

mw.kalturaPluginWrapper(function() {
    mw.PluginManager.add( 'myPlugin', mw.KBasePlugin.extend({
        setup: function() {
            var kdp = this.getPlayer();
            kdp.addJsListener('playbackComplete', this.playbackComplete);
            document.onkeydown = function(e) {
                var kdp = document.getElementById('player_kaltura');
                switch(e.keycode) {
                    case 37: //left arrow
                        kdp.sendNotification('doSeek', kdp.evaluate('{video.player.currentTime}') - 10);
                    case 39: //right arrow
                        kdp.sendNotification('doSeek', kdp.evaluate('{video.player.currentTime}') + 10);

        playbackComplete: function() {
           alert('Video ended');

And that is all.

  1. Hey Alon, Thank you for the nice post I was serching somthing like this only. I have a quession here, from where are you hosting your js/myPlugin.js file, I mean from your server or is there a way we can add this file in KMC itself?

    1. Hi Himanshu,
      The ‘js.myPlugin.js’ represents a link to the plugin file. It doesn’t matter where the file is hosted as long as you have access to it. You can upload the file to your Kaltura as a data-entry via the Kaltura API.

  2. Thanks Alon for the quick reply. Actually I m getting confused here. What I want to do is create a simple plugin which capture all events performed in my kaltura player. So, whenever and wherever player is playing something I can capture the events. I mean I want to do something just like Google Analytics Plugin is doing. As I want all player events to be sent to my server instead of google analytics server. I have just started looking into kaltura APIs so I dnt have much idea how to do this. Can you please provide some guide to create such plugin.

    1. Hi Himanshu,
      Sound like an interesting project, and we definitely can offer our services and build a custom plugin to support the requirements.
      I will contact you shortly,
