AVPlayer seekToTime: Poor performance while looping short videos

this is my first question, but I've readed StackOverflow for years. Well the thing is that I must concatenate a set of videos (MP4) in a particular order, and the last one must loop continuously. Okay, let's try AVFoundation.

I've defined all the elements such as AVComposition, AVURLAsset and AVPlayerItem. Then I build the AVPlayer and the AVPlayerLayer. Everything is okay and the videos are played in the correct order but... (and here comes the problem)

I can note a tiny flick when the AVPlayer passes from one video to the next one. I can ignore that one, but when AVPlayer reaches AVPlayerItem's end, and the selector is called for AVPlayerItemDidPlayToEndTimeNotification, I use seekToTime to move the reading head to the correct and then play it again. Works fine, but a GREAT flick is repeated when using seekToTime and playing again. I cannot allow that.

Does anybody know how to repeat the last asset on AVPlayerItem continuously and without flicks?

Thank you all.

Absolutely stupid,

Friends, when making video manipulation apps be sure that the videos don't have annoying black frames. That was the root of all problems. [AVPlayer seekToTime:] works perfectly.

Thanks for your time and patience
