Method | Description |
|---|---|
ICameraCaptureSampleSink::OnSampleAvailable method for Windows Phone 8 | Performs caller-implemented actions each time an encoded audio or video sample is captured. |
Use this sink by calling the IAudioVideoCaptureDeviceNative::SetAudioSampleSink method for Windows Phone 8 or the IAudioVideoCaptureDeviceNative::SetVideoSampleSink method for Windows Phone 8.
This sink only receives samples while the AudioVideoCaptureDevice object is recording. Recording starts when the StartRecordingToSinkAsync method is called and ends after StopRecordingAsync is called. Specify the audio and video encoding formats with the AudioEncodingFormat and VideoEncodingFormat properties, respectively.
Whether AudioVideoCaptureDevice captures audio or video is determined by which open method you use to create the capture device. Use OpenAsync for video samples with audio, OpenForAudioOnlyAsync for audio samples, and OpenForVideoOnlyAsync for video samples without audio.
