July 21, 2014
Applies to: Windows Phone 8 and Windows Phone Silverlight 8.1 only
Sets the sink that will receive encoded audio samples during recording.
HRESULT SetAudioSampleSink( [in] ICameraCaptureSampleSink* pSink );
To access the IAudioVideoCaptureDeviceNative interface, invoke IUnknown::QueryInterface on the instance of the AudioVideoCaptureDevice class, using the UUID of IAudioVideoCaptureDeviceNative. These methods are not directly available from managed projections, but you can write your own Windows Runtime objects that wrap them.
This sink only receives samples while AudioVideoCaptureDevice is recording. Recording starts when the StartRecordingToSinkAsync method is called and ends after StopRecordingAsync is called. Specify the audio and video encoding formats using the AudioEncodingFormat and VideoEncodingFormat properties, respectively.
Whether AudioVideoCaptureDevice captures audio or video is determined by which open method is used to create the capture device. Use the OpenAsync method for video samples with audio, OpenForAudioOnlyAsync for audio samples, and OpenForVideoOnlyAsync for video samples without audio.
