• About Playback

• Kineto’s video communication

• About Buffering

  • playbackLikelyToKeepUp indicates whether it is likely to finish without stalling
  • PlaybackBufferFull is true when everything is loaded
  • playbackBufferEmpty is true when it is likely to stall or when it is stalling

• AVPlayer.rate = 1 for playback?

  • Is this an old version?

AVPlayer.rate is complicated

• If you want to use the old version of the image above

  • automaticallyWaitsToMinimizeStalling = false
  • setRate(time:atHostTime:) needs to be set to false as well
  • Remember this

• If you want to play multiple videos in succession, use AVQueuePlayer

  • Are we using AVPlayerLooper now?

• They also talk about Color Space, but I’m not interested so I’ll skip it

• Best Practices for Playback Startup Time

• - It seems better to set various settings and then call play() before setting the playerItem - If you do it the other way around, the AVPlayer gets confused when you only want to display a static image (one frame)
