Question

I'm building an app which needs high playback performance. I choose Quicktime as video engine. I experimented different playback performance with different version:

  • v7.1.3 has the best performance : when pressing play in the QT player, the video starts immediatly
  • newer quicktime release have very poor playback performance, the delay between pressing play and the effective video playback is about 400ms. Is there a way to improve this latency in the latest release?
Was it helpful?

Solution 2

I finally processed the sound with a custom library and used QuickTime only for video display in sync.

Sounds like you're seeing precaching. Can you adjust the cache settings?
