how to improve the performance of seek when using avplayer

I'm using AVPlayer to create a video player, but the seekToTime method is pretty slow. I'm impressed by the seeking performance of Apple's app "Photos". Does anyone have any idea how Apple managed to do such a quick seeking?

Does it has anything to do with threads? I tried to put the seekToTime call in a dispatch queue, it does't help either.

Solution

  • I have found the solution.

    If I use seekToTime to do the scrubbing, it's pretty slow. What I should use is a method called stepByCount from AVPlayerItem.
