Player API documentation

The API allows you to manage the player settings using JavaScript and collect data about its use for further analysis. 

Player Initialization via iframe

Copy the iFrame code from the VOD/broadcast settings in your account.

Add the id='gplayer' parameter to the iFrame and paste it into the site code.

Example of the iFrame code from the control panel with the id= 'gplayer' parameter:

<iframe width="640" height= " 360 " src="" allow= 'autoplay' allowfullscreen frameborder="0" id= 'gplayer'></iframe>


  • width - the width of the player,
  • height - the height of the player,
  • src - content URL (link to VOD or live stream),
  • allowfullscreen - if the parameter is added to the iframe, a button for switching to full-screen mode is added to the controls of the player,
  • frameborder - border of the player. The default value is "0" (the border shouldn't be visible),
  • id - the player ID. Required for further initialization of the player when calling API methods.

After the iframe add the following code to initialize the player:

<script type="text/javascript" charset="utf-8" src=""></script>
  window.onload = function() {
    let gplayerAPI = new GcorePlayer.gplayerAPI(document.getElementById('gplayer'));

The onload event on window is triggered when the entire page, including the iframe, is loaded. Then there is an indication of the player to which the API call will be applied.

Example of the full player initialization code and iframe for HTML page:

<!DOCTYPE html>
<iframe width="640" height="360" src="" allowfullscreen frameborder="0" id='gplayer'></iframe>
<script type="text/javascript" charset="utf-8" src=""></script>
window.onload = function() {
let gplayerAPI = new GcorePlayer.gplayerAPI(document.getElementById('gplayer'));

Calling player methods

You can start calling methods once you receive the ready event:

gplayerAPI.on('ready', () => {
console.log('[Event]', 'ready')
gplayerAPI.method({name: 'play'})

Available methods:

Method name Data type Description
getCurrentTime Number  The current time in seconds
getDuration Number  The duration time in seconds 
getVolume Number  Volume. Value from 0 (sound off, mute) to 100 (maximum volume)
isDvrEnabled Boolean

 Shows DVR service status:

  • true - DVR is enabled,
  • false - DVR is disabled
isPlaying Boolean

 Checks if the player is playing:

  • true - the current source is playing,
  • false - playback is off/stopped/not started
mute    Turns off the sound
unmute    Turns on the sound 
pause    Pauses playback 
play    Starts playback 
resize Object  Modifies the canvas of the player 
seek Number

 Rewinds playback (seconds).

 For example, (120) rewinds the video and starts at 2 minutes

seekPercentage Number

 Rewinds playback (percent).

 For example, (50) rewinds the video and starts playing from the middle of the video

setVolume Number  Sets the volume for the current video
stop    Stops playback of the current video

Method call pattern:

gplayerAPI.method({name: 'isPlaying', params: {}, callback: (res) => {

name - the name of the function,

params - the parameters of the function,

callback - the callback function.


window.onload = function() {
let gplayerAPI = new GcorePlayer.gplayerAPI(document.getElementById('gplayer'));
let flag = true;
gplayerAPI.on('ready', () => {
console.log('[Event]', 'ready')
gplayerAPI.method({name: 'play'})

gplayerAPI.on('play', () => {
if(flag) {
gplayerAPI.method({name: 'pause'})
flag = false;
console.log('[Event]', 'play')

gplayerAPI.on('pause', () => {
console.log('[Event]', 'pause')

gplayerAPI.on('volumeupdate', () => {
console.log('[Event]', 'volumeupdate')

gplayerAPI.on('timeupdate', () => {
console.log('[Event]', 'timeupdate')

gplayerAPI.on('stop', () => {
console.log('[Event]', 'stop')

gplayerAPI.on('seek', () => {
console.log('[Event]', 'seek')

gplayerAPI.on('resize', () => {
console.log('[Event]', 'resize')

gplayerAPI.on('fullscreen', () => {
console.log('[Event]', 'fullscreen')

gplayerAPI.on('error', () => {
console.log('[Event]', 'error')

gplayerAPI.on('ended', () => {
console.log('[Event]', 'ended')

API testing tool

You can test the player API online here.

Copy and paste the iframe from your control panel in the upper field, and click on the "Upload your iframe" button. To search for an iFrame in your account, use the guides from the following articles: for broadcasts (step 7), for VOD (step 6), and for playlists (step 7).


Dark gray buttons are for the functions available for calling, white buttons are for the functions that require values setting. Events are logged in the "Status" window.
