## Declaration

## Mentioned in

## Discussion

Discussion Use this mode when you want to use the remote device’s built-in media player instead of launching a custom application. This provides a standardized playback experience without requiring a corresponding application to be installed on the remote device. To support the AVSystemRoute.LaunchMode.player launch mode, the MDESupportsUniversalURLPlayback key must be set in the app’s Info.plist file. For example: <key>MDESupportsUniversalURLPlayback</key> <true/> important: If MDESupportsUniversalURLPlayback is not set to true, calls to start() fail.
