Search in playlist

   {"title":"Serie 1","file":"//site.com/s1.mp4","id":"s1"},
   {"title":"Serie 2","file":"//site.com/s2.mp4","id":"s2"},
   {"title":"Serie 3","file":"//site.com/s3.mp4","id":"s3"}
]

Now you can find and open the file with JS API (the player will wait for the start)

player.api("find","s2");

You can immediately autostart playback (on mobile requires user action or mute)

player.api("play","id:s2");

You can run the file from the desired second by adding the seek command in square brackets

player.api("play","id:s2[seek:10]");

The query playlist_id returns the id of the active file

alert(player.api("playlist_id"));
