For documentation and support, please visit the JW Player Support Site.

We have several articles and examples on the JW Player Support Site.

The example below will find the element with an id of myVideoId and render a video player into it. We will then create an event handler to watch for when someone changes the volume.

	jwplayer('myVideoId').setup({
		file: '/uploads/example.mp4',
	});

	jwplayer('myVideoId').onVolume(function(event) {
		console.log('The volume has changed', event);
	});

Note that we could also use functions getVolume, setVolume and others which can be found here.

For our javascript code, we follow the Douglas Crockford Style guide

To build the JW Player, you will need the following software:

• Flex SDK 4.1: http://sourceforge.net/adobe/flexsdk/wiki/Downloads/
• Ant 1.7.0: http://ant.apache.org/bindownload.cgi

To compile with Flex and Ant, you'll first need to modify the build.properties file found in the build folder:

1. Set flexsdk to the install location of the Flex SDK (e.g. /usr/local/bin/flex/)
2. Set execextension to .exe if you're using Windows; otherwise leave it blank.

You can now compile the player using Ant:

ant -buildfile build\build.xml

If the build is successful, the new player assets (jwplayer.js, jwplayer.html5.js, jwplayer.flash.swf) will appear in the bin-release folder.
