I’ve been lately hacking a new app, Fireplace Deluxe for the new Apple TV thingy, and had to deal with looping videos.
The usual way to implement this is getting a notification for AVPlayerItemDidPlayToEndTimeNotification and rewind the video. But this introduces some milliseconds of lag and give us some undesired hiccups.
There is not much info about this but a nice way to solve the issue is by using the AVQueuePlayer and inserting videos in the queue indefinitely as long as they are being played.
This will render a nice seamless video loop without annoying hiccups.
