 Enable the buttons that your app will use by setting the corresponding "is enabled" property of the **SystemMediaTransportControls** object, such as [**IsPlayEnabled**](/uwp/api/windows.media.systemmediatransportcontrols.isplayenabled), [**IsPauseEnabled**](/uwp/api/windows.media.systemmediatransportcontrols.ispauseenabled), [**IsNextEnabled**](/uwp/api/windows.media.systemmediatransportcontrols.isnextenabled), and [**IsPreviousEnabled**](/uwp/api/windows.media.systemmediatransportcontrols.ispreviousenabled). See the **SystemMediaTransportControls** reference documentation for a complete list of available controls.

 ## Handle system media transport controls button presses
 
 The [**ButtonPressed**](/uwp/api/windows.media.systemmediatransportcontrols.buttonpressed) event is raised by the system transport controls when one of the enabled buttons is pressed. The [**Button**](/uwp/api/windows.media.systemmediatransportcontrolsbuttonpressedeventargs.button) property of the [**SystemMediaTransportControlsButtonPressedEventArgs**](/uwp/api/Windows.Media.SystemMediaTransportControlsButtonPressedEventArgs) passed into the event handler is a member of the [**SystemMediaTransportControlsButton**](/uwp/api/Windows.Media.SystemMediaTransportControlsButton) enumeration that indicates which of the enabled buttons was pressed.
 
 In order to update objects on the UI thread from the [**ButtonPressed**](/uwp/api/windows.media.systemmediatransportcontrols.buttonpressed) event handler, such as a [**MediaPlayerElement**](/windows/windows-app-sdk/api/winrt/microsoft.ui.xaml.controls.mediaplayerelement) object, you must marshal the calls through the [**DispatcherQueue**](/windows/windows-app-sdk/api/winrt/microsoft.ui.dispatching.dispatcherqueue.tryenqueue). This is because the **ButtonPressed** event handler is not called from the UI thread and therefore an exception will be thrown if you attempt to modify the UI directly.

 ## Update the system media transport controls with the current media status
 
 You should notify the [**SystemMediaTransportControls**](/uwp/api/Windows.Media.SystemMediaTransportControls) when the state of the media has changed so that the system can update the controls to reflect the current state. To do this, set the [**PlaybackStatus**](/uwp/api/windows.media.systemmediatransportcontrols.playbackstatus) property to the appropriate [**MediaPlaybackStatus**](/uwp/api/Windows.Media.MediaPlaybackStatus) value from within the [**CurrentStateChanged**](/uwp/api/windows.media.playback.mediaplayer.currentstatechanged) event of the [**MediaPlayer**](/uwp/api/windows.media.playback.mediaplayer), which is raised when the media state changes.

 ## Update the system media transport controls with media info and thumbnails
 
 Use the [**SystemMediaTransportControlsDisplayUpdater**](/uwp/api/Windows.Media.SystemMediaTransportControlsDisplayUpdater) class to update the media info that is displayed by the transport controls, such as the song title or the album art for the currently playing media item. Get an instance of this class with the [**SystemMediaTransportControls.DisplayUpdater**](/uwp/api/windows.media.systemmediatransportcontrols.displayupdater) property. For typical scenarios, the recommended way to pass the metadata is to call [**CopyFromFileAsync**](/uwp/api/windows.media.systemmediatransportcontrolsdisC:\windows-code-snippets-pr\winappsdk\audio-video-camera\media-source-winui\cs\MediaSourceplayupdater.copyfromfileasync), passing in the currently playing media file. The display updater will automatically extract the metadata and thumbnail image from the file.
 
 Call the [**Update**](/uwp/api/windows.media.systemmediatransportcontrolsdisplayupdater.update) to cause the system media transport controls to update its UI with the new metadata and thumbnail.

 If your scenario requires it, you can update the metadata displayed by the system media transport controls manually by setting the values of the [**MusicProperties**](/uwp/api/windows.media.systemmediatransportcontrolsdisplayupdater.musicproperties), [**ImageProperties**](/uwp/api/windows.media.systemmediatransportcontrolsdisplayupdater.imageproperties), or [**VideoProperties**](/uwp/api/windows.media.systemmediatransportcontrolsdisplayupdater.videoproperties) objects exposed by the [**DisplayUpdater**](/uwp/api/windows.media.systemmediatransportcontrols.displayupdater) class.

 The system transport controls display information about the timeline of the currently playing media item, including the current playback position, the start time, and the end time of the media item. To update the system transport controls timeline properties, create a new [**SystemMediaTransportControlsTimelineProperties**](/uwp/api/Windows.Media.SystemMediaTransportControlsTimelineProperties) object.
