This version is adding improvements for ABR playback. It implements a cooldown mechanism to control the next up-switch. Too frequent up- & down-switches will be prevented. This improves the user experience especially in case of slight but frequent buffer impacts e.g. in case of limited network ressources. Furthermore this release includes an improvement for classic playback on iOS 15 to avoid buffer impacts after adjusting latency. Also the visual switching behaviour on iOS has been improved to prevent a possible black frame effect.
