MediaCapture.InitializeAsync() | initializeAsync() method

Initializes the MediaCapture object, using default settings.

Syntax


mediaCapture.initializeAsync().done( /* Your success and error handlers */ );

public IAsyncAction InitializeAsync()

Public Function InitializeAsync() As IAsyncAction

public:
IAsyncAction^ InitializeAsync()

Parameters

This method has no parameters.

Return value

Type: IAsyncAction

Returns a IAsyncAction object that is used to control the asynchronous operation.

Remarks

InitializeAsync will launch a consent prompt to get the user's permission for the app to access the microphone or camera. InitializeAsync should be called from the main UI thread of your app. In apps that use C# or C++, the first use of the MediaCapture object to call InitializeAsync should be on the STA thread. Calls from an MTA thread may result in undefined behavior.

For how-to guidance on initializing and shutting down the MediaCapture object, see Basic photo, video, and audio capture with MediaCapture.
