Playlist plugin functionality on JW Player

We have a custom video screening room built on PHP and streaming content from Amazon S3 via our JW Player. We would like to have a video playlist functionality set up on the JW Player. We had the Flow plugin for JW Player installed, but had to remove it, because our previous developer said it was breaking HTML5 playback on the player. We would like to get the playlist function working for our screening room. Thank you.
