Windows

Linux & Embedded Linux

OS X & iOS

Multimedia support for apple products are provided by two plugins. The QuickTime 7 plugin is the legacy plugin, providing limited multimedia support to OS X 10.6, and is not actively developed. The AVFoundation plugin is available on OS X 10.7+ as well as iOS. This is the actively developed plugin and should be used where possible.

Android

Android Base-layer

Blackberry 10 (QNX)

QtMultimedia Plugin Interfaces

QtMultimedia's functionality for a given platform is defined using the Qt plugin system through the implementation of interfaces. These interfaces can be seen split several ways, but for our purposes they will be split between the high level and low level API's.

High-level Multimedia Interfaces:

Interface Description
