The Queueing functions section has been updated to explain that you can use either argument syntax or object syntax to call all of those functions. Note that the API may support additional functionality in object syntax that the argument syntax does not support.
In addition, the descriptions and examples for each of the video queueing functions have been updated to reflect the newly added support for object syntax. (The API's playlist queueing functions already supported object syntax.)
When called using object syntax, each of the video queueing functions supports an endSeconds property, which accepts a float/integer and specifies the time when the video should stop playing when playVideo() is called.
The getVideoStartBytes method has been deprecated. The method now always returns a value of 0.
The example in the Loading a video player section that demonstrates how to manually create the <iframe> tag has been updated to include a closing </iframe> tag since the onYouTubeIframeAPIReady function is only called if the closing </iframe> element is present.
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.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.
The Operations section now explains that the API supports the setSize() and destroy() methods. The setSize() method sets the size in pixels of the <iframe> that contains the player and the destroy() method removes the <iframe>.
We have removed the experimental status from the IFrame Player API.
The Loading a video player section has been updated to point out that when inserting the <iframe> element that will contain the YouTube player, the IFrame API replaces the element specified in the constructor for the YouTube player. This documentation change does not reflect a change in the API and is intended solely to clarify existing behavior.
In addition, that section now notes that the insertion of the <iframe> element could affect the layout of your page if the element being replaced has a different display style than the inserted <iframe> element. By default, an <iframe> displays as an inline-block element.
The Operations section has been updated to explain that the IFrame API supports a new method, getIframe(), which returns the DOM node for the IFrame embed.
The Requirements section has been updated to note the minimum player size. {{ minimum_player_size }}
