Starting with iOS 16, iPadOS 16, macOS Ventura, and tvOS 16, apps that use Apple’s video player can offer a native playback speed menu. However, this feature is optional for developers, so the functionality may not be available in some apps.
Apple’s default playback speed options are 0.5×, 1.0×, 1.25×, 1.5× and 2.0×, but developers can modify the speed list.
In supported iPhone and iPad apps, the playback speed menu can be accessed by tapping the icon with three dots surrounded by a circle. In compatible Mac applications, the menu can be found by clicking “»” and selecting Playback Speed. In supported Apple TV apps, to the left of the subtitle icon is a new timer icon for playback speed.
For developers, Apple says that all apps using the new iOS, iPadOS, macOS, and tvOS SDKs will get this playback speed functionality automatically, with no additional changes required. Developers who wish to disable menus entirely can use the new API added to AVPlayer, with more details available In this video of WWDC 2022 session,
Some apps that use custom video players on iOS such as YouTube already provide playback speed control, as do some Apple apps such as developer apps.
