Occurs when pointer capture previously held by this element moves to another element or elsewhere.
Occurs when the pointer device that previously initiated a Press action is released, while within this element. Note that the end of a Press action is not guaranteed to fire a PointerReleased event; other events may fire instead. For more info, see Remarks.

Use the FileOpenPicker class to select a media file. Call PickSingleFileAsync to launch the file picker and get the file. Then call Play on the MediaPlayerElement. MediaPlayer to start the media. You can use the PosterSource property to provide your MediaPlayerElement with a visual representation before the media is loaded.
A PosterSource is an image, such as a screen shot or movie poster, that is displayed in place of the media. The PosterSource is displayed in the following situations:.
Here's a MediaPlayerElement with its Source set to an album track, and it's PosterSource set to an image of the album cover. Typically, a device dims the display and eventually turns it off to save battery life when the user is away, but video apps need to keep the screen on so the user can see the video. To prevent the display from being deactivated when user action is no longer detected, such as when an app is playing video, you can call DisplayRequest.
The DisplayRequest class lets you tell Windows to keep the display turned on so the user can see the video. To conserve power and battery life, you should call DisplayRequest. RequestRelease to release the display request when it is no longer required.
Windows automatically deactivates your app's active display requests when your app moves off screen, and re-activates them when your app comes back to the foreground. Note If MediaPlayerElement. IsFullWindow is set to true and media is playing, the display will automatically be prevented from deactivating.
Call RequestActive to notify Windows that the app requires the display to remain on. Call RequestRelease to release the display request whenever video playback is stopped, paused, or interrupted by a playback error. When your app no longer has any active display requests, Windows saves battery life by dimming the display and eventually turning it off when the device is not being used.
Each MediaPlayerElement. PlaybackSession to detect situations when you should release the display request. Then, use the NaturalVideoHeight property to determine whether an audio or video file is playing, and keep the screen active only if video is playing.
MediaPlayerElement provides numerous properties, methods, and events for controlling audio and video playback through the MediaPlayerElement. MediaPlayer property. For a full listing of properties, methods, and events, see the MediaPlayer reference page. For more complex media playback scenarios like playing a playlist, switching between audio languages or creating custom metadata tracks set the MediaPlayerElement. See the Media playback page for more information on how to enable various advanced media functionality.
Set the IsFullWindow property to enable and disable full window rendering. When you programmatically set full window rendering in your app, you should always use IsFullWindow instead of doing it manually. IsFullWindow insures that system level optimizations are performed that improve performance and battery life. If full window rendering is not set up correctly, these optimizations may not be enabled.
The code below implements the functionality of the sample UI controls. The Play , Pause , and Stop methods are used to respectively play, pause and stop the media.
Changing the Position property of the MediaElement allows you to skip around in the media. Finally, the Volume and SpeedRatio properties are used to adjust the volume and playback speed of the media.
