# Qt Multimedia on macOS and iOS

This page covers the availability of Qt Multimedia features on iOS and macOS.

## Limitations

Since Qt Multimedia for iOS uses the camera and microphone, the `Info.plist` assigned to QMAKE_INFO_PLIST in the project file must contain the keys `NSCameraUsageDescription` and `NSMicrophoneUsageDescription`. Otherwise, the application will abort on startup. See Info.plist documentation from Apple for more information regarding this key.

## Use of FFmpeg libraries on iOS

FFmpeg binaries from the online installer must be embedded into the application's bundle. To embed these libraries, you can add the qt6_add_ios_ffmpeg_libraries() command to the app's CMakeLists.txt file:

     qt_add_ios_ffmpeg_libraries(mytarget)

When using QMake, add the following to your `.pro` file:

     CONFIG += add_ios_ffmpeg_libraries

Note: The FFmpeg binaries from the online installer are built for arm64 and arm64-simulator to ensure they pass validation with Apple Store Connect and can be used when running the iOS simulator.

See also qt_add_ios_ffmpeg_libraries().
