JavaFX – YouTube

In previous blog I gave a simple example for JavaFX – JavaScript communication. Here we will see how to utilize this feature so as to integrate YouTube with JavaFX browser deployment. YouTube provides Data and Player APIs. We can utilize them to integrate YouTube presentation layer to JavaFX.

Given below is JavaFX app which uses YouTube Data APIs to search for videos with specified tag and displays the thumbnail images. User can click on thumbnail to view the video. The video can be controlled from JavaFX using JavaScript APIs. I’m sure a good designer can provide a much better seamless integration

Click on above image to launch the applet.
Note: Require JavaSE 6 Update 10 or above.
I’m not responsible for content shown in video

I have used YouTube Search APIs. It provides output in various formats – atom, rss, json and json-in-script. I have used the default ATOM format. Even though its using ATOM format, most of required attributes are provided in custom tags as shown below. Hence even though I used AtomTask to parse the feed, I still had to parse the custom tags in onForeignEvent : function(:Event):Void method. Details of parser is available in YTDataTask.fx.

YouTube provides “Chromeless Player” with JavaScript API support. We can obtain the videoid using above Data APIs and pass this to player using JavaScript APIs. We can perform operations such as – load video, play, pause, stop, seek, mute/un-mute – on video. Refer to JavaScript API documentation for more information.

All these APIs are encapsulated in a file – JavaYT.js. A Java wrapper for this javascript file is provided so as to invoke these APIs from Java – JavaYTUtil.java. This in turn uses JavaScriptUtil.java as shown in previous post.

Both YouTube player and JavaFX is added to a Table so as to render them together. Please refer to JavaFXYT.html for more information.
