The IFrame player API lets you embed a YouTube video player on your website and control the player using JavaScript.

Using the API's JavaScript functions, you can queue videos for playback; play, pause, or stop those videos; adjust the player volume; or retrieve information about the video being played. You can also add event listeners that will execute in response to certain player events, such as a player state change.

This guide explains how to use the IFrame API. It identifies the different types of events that the API can send and explains how to write event listeners to respond to those events. It also details the different JavaScript functions that you can call to control the video player as well as the player parameters you can use to further customize the player.

Requirements

The user's browser must support the HTML5 postMessage feature. Most modern browsers support postMessage.

Embedded players must have a viewport that is at least 200px by 200px. If the player displays controls, it must be large enough to fully display the controls without shrinking the viewport below the minimum size. We recommend 16:9 players be at least 480 pixels wide and 270 pixels tall.

Any web page that uses the IFrame API must also implement the following JavaScript function:

  • onYouTubeIframeAPIReady – The API will call this function when the page has finished downloading the JavaScript for the player API, which enables you to then use the API on your page. Thus, this function might create the player objects that you want to display when the page loads.

Getting started

The sample HTML page below creates an embedded player that will load a video, play it for six seconds, and then stop the playback. The numbered comments in the HTML are explained in the list below the example.





Revision history

April 27, 2021

The Getting Started and Loading a Video Player sections have been updated to include examples of using a playerVars object to customize the player.

October 13, 2020

Note: This is a deprecation announcement for the embedded player functionality that lets you configure the player to load search results. This announcement affects the IFrame Player API's queueing functions for lists, cuePlaylist and loadPlaylist.

This change will become effective on or after 15 November 2020. After that time, calls to the cuePlaylist or loadPlaylist functions that set the listType property to search will generate a 4xx response code, such as 404 (Not Found) or 410 (Gone). This change also affects the list property for those functions as that property no longer supports the ability to specify a search query.

As an alternative, you can use the YouTube Data API's search.list method to retrieve search results and then load selected videos in the player.

October 24, 2019

The documentation has been updated to reflect the fact that the API no longer supports functions for setting or retrieving playback quality. As explained in this YouTube Help Center article, to give you the best viewing experience, YouTube adjusts the quality of your video stream based on your viewing conditions.

The changes explained below have been in effect for more than one year. This update merely aligns the documentation with current functionality:

  • The getPlaybackQuality, setPlaybackQuality, and getAvailableQualityLevels functions are no longer supported. In particular, calls to setPlaybackQuality will be no-op functions, meaning they will not actually have any impact on the viewer's playback experience.
  • The queueing functions for videos and playlists -- cueVideoById, loadVideoById, etc. -- no longer support the suggestedQuality argument. Similarly, if you call those functions using object syntax, the suggestedQuality field is no longer supported. If suggestedQuality is specified, it will be ignored when the request is handled. It will not generate any warnings or errors.
  • The onPlaybackQualityChange event is still supported and might signal a change in the viewer's playback environment. See the Help Center article referenced above for more information about factors that affect playback conditions or that might cause the event to fire.

May 16, 2018

The API now supports features that allow users (or embedders) to control the viewing perspective for 360° videos:

  • The getSphericalProperties function retrieves the current orientation for the video playback. The orientation includes the following data:
    • yaw - represents the horizontal angle of the view in degrees, which reflects the extent to which the user turns the view to face further left or right
    • pitch - represents the vertical angle of the view in degrees, which reflects the extent to which the user adjusts the view to look up or down
    • roll - represents the rotational angle (clockwise or counterclockwise) of the view in degrees.
    • fov - represents the field-of-view of the view in degrees, which reflects the extent to which the user zooms in or out on the video.
  • The setSphericalProperties function modifies the view to match the submitted property values. In addition to the orientation values described above, this function supports a Boolean field that indicates whether the IFrame embed should respond to DeviceOrientationEvents on supported mobile devices.

This example demonstrates and lets you test these new features.

June 19, 2017

This update contains the following changes:

  • Documentation for the YouTube Flash Player API and YouTube JavaScript Player API has been removed and redirected to this document. The deprecation announcement for the Flash and JavaScript players was made on January 27, 2015. If you haven't done so already, please migrate your applications to use IFrame embeds and the IFrame Player API.

August 11, 2016

This update contains the following changes:

  • The newly published YouTube API Services Terms of Service ("the Updated Terms"), discussed in detail on the YouTube Engineering and Developers Blog, provides a rich set of updates to the current Terms of Service. In addition to the Updated Terms, which will go into effect as of February 10, 2017, this update includes several supporting documents to help explain the policies that developers must follow.

    The full set of new documents is described in the revision history for the Updated Terms. In addition, future changes to the Updated Terms or to those supporting documents will also be explained in that revision history. You can subscribe to an RSS feed listing changes in that revision history from a link in that document.

June 29, 2016

This update contains the following changes:

  • The documentation has been corrected to note that the onApiChange method provides access to the captions module and not the cc module.

June 24, 2016

The Examples section has been updated to include an example that demonstrates how to use the API with an existing tag since the onYouTubeIframeAPIReady function is only called if the closing element is present.

August 6, 2012

This update contains the following changes:

  • The Operations section has been expanded to list all of the supported API functions rather than linking to the JavaScript Player API Reference for that list.

  • The API supports several new functions and one new event that can be used to control the video playback speed:

    • Functions

      • getAvailablePlaybackRates – Retrieve the supported playback rates for the cued or playing video. Note that variable playback rates are currently only supported in the HTML5 player.
      • getPlaybackRate – Retrieve the playback rate for the cued or playing video.
      • setPlaybackRate – Set the playback rate for the cued or playing video.
    • Events

      • onPlaybackRateChange – This event fires when the video's playback rate changes.

July 19, 2012

This update contains the following changes:

  • The new getVideoLoadedFraction method replaces the now-deprecated getVideoBytesLoaded and getVideoBytesTotal methods. The new method returns the percentage of the video that the player shows as buffered.

  • The onError event may now return an error code of 5, which indicates that the requested content cannot be played in an HTML5 player or another error related to the HTML5 player has occurred.

  • The Requirements section has been updated to indicate that any web page using the IFrame API must also implement the onYouTubeIframeAPIReady function. Previously, the section indicated that the required function was named onYouTubePlayerAPIReady. Code samples throughout the document have also been updated to use the new name.

    Note: To ensure that this change does not break existing implementations, both names will work. If, for some reason, your page has an onYouTubeIframeAPIReady function and an onYouTubePlayerAPIReady function, both functions will be called, and the onYouTubeIframeAPIReady function will be called first.

  • The code sample in the Getting started section has been updated to reflect that the URL for the IFrame Player API code has changed to http://www.youtube.com/iframe_api. To ensure that this change does not affect existing implementations, the old URL (http://www.youtube.com/player_api) will continue to work.

July 16, 2012

This update contains the following changes:

  • The Operations section now explains that the API supports the setSize() and destroy() methods. The setSize() method sets the size in pixels of the
