player.currentItem(2);
// 2

player.playlist(samplePlaylist);
player.src('http://example.com/video.mp4');
player.playlist.currentItem(); // -1

player.playlist.contains(Any item) -> Boolean

This function allows you to ask the playlist whether a string, source object, or playlist item is contained within it. Assuming the above playlist, consider the following example:

playlist.contains('http://media.w3.org/2010/05/sintel/trailer.mp4')
// true

playlist.contains([{

  }]
});

If you are at the end of the playlist, you will not be able to proceed past the end and instead will not receive anything back;

player.playlist.next();
// {
//   sources: [{
//     src: 'http://media.w3.org/2010/05/bunny/trailer.mp4',
//     type: 'video/mp4'
//   }],
//   poster: 'http://media.w3.org/2010/05/bunny/poster.png'

player.playlist.currenItem(player.playlist().length - 1); // set to last item
// 4
player.playlist.next();
// undefined

player.playlist.previous() -> Object

You will receive the new playlist item back from this call. player.playlist.currentItem will be updated to return the new index. If you are at the start of the playlist, you will not be able to proceed past the start and instead will not receive anything back;

player.playlist.currenItem(1); // set to second item in the playlist
// 1
player.playlist.previous();
// {
//   sources: [{
//     src: 'http://media.w3.org/2010/05/sintel/trailer.mp4',
//     type: 'video/mp4'
//   }],
//   poster: 'http://media.w3.org/2010/05/sintel/poster.png'
// }


player.playlist.currenItem();
// 0
player.playlist.previous();
// undefined

player.playlist.autoadvance([Number timeout]) -> undefined

This function allows you to set up playlist auto advancement. Once enabled it will wait a timeout amount of milliseconds at the end of a video before proceeding automatically to the next video. Any value which is not a positive, finite, integer, will be treated as a request to cancel and reset the auto advancing. If you change autoadvance during a timeout period, the auto advance will be canceled and it will not advance the next video but it will use the new timeout value for the following videos.

player.playlist.autoadvance(0); // will not wait before loading in the next item
player.playlist.autoadvance(5); // will wait for 5 seconds before loading in the next item
player.playlist.autoadvance(null); // reset and cancel the auto advance

  console.log(player.playlist());
});

// [1,2,3]

player.playlist([4,5,6]);
