Enumeration Values

Value Description
Buffering The MediaElement is loading the media for playback. Its Position does not advance during this state. If the MediaElement was already playing video, it continues to display the last displayed frame.
Closed The MediaElement contains no media. The MediaElement displays a transparent frame.
Error The MediaElement encountered an error during media playback. If the MediaElement was playing video, it continues to display the last displayed frame. This MediaElement changes to this state after raising the MediaFailed event.
Opening The MediaElement is validating and attempting to open the Uri specified by its Source property. While in this state, the MediaElement queues any Play, Pause, or Stop commands it receives and processes them if the media is successfully opened.
Paused The MediaElement does not advance its Position. If the MediaElement was playing video, it continues to display the current frame.
Playing The MediaElement is playing the media specified by its source property. Its Position advances forward.
Stopped The MediaElement contains media but is not playing or paused. Its Position is 0 and does not advance. If the loaded media is video, the MediaElement displays the first frame.

Media state is typically used to adjust the visual appearance and current functionality of media transport controls.

Examples

The following example demonstrates one way to display the CurrentState of a MediaElement. It creates a MediaElement and several buttons for controlling media playback. To display the current state of the MediaElement, the example registers for the CurrentStateChanged event and uses an event handler to update a TextBlock.
