Problem with changing swarmId.

[rozenrod]

I'm using Playerjs with a playlist of 5 files (5 series). If I do not specify the swarmId myself, then when I change the series, everything works and the swarmId itself is updated. But when I set the swarmId parameter to a function that returns return "https://site .com/2" then the player can only run 1 file, but it freezes when changing the series.
