Play N videos in sync

This is a toy app to try and understand how many videos I can play simultaneously on iOS. Some forums say it's 4. I seem to hit a limit at 16.

Behaviours to try out:

• Can I quickly toggle between several videos within a same AVPlayerLayer, with random seekTimes?
• Can I sync video playback on an external clock (driven by the audio render callback, for instance)?
