Important noteImportant Note:

multiple devices The 7x27a processor allows audio input on only one stereo bus at a time. This means applications cannot concurrently capture more than one audio source on these devices. If your application is using AudioSink along with FileSink on 7x27a devices, AudioSink will not get audio samples and AudioCaptureDevice will be set to null. FileSink works fine on the 7x27a processor. FileSink or AudioSink work correctly if used independently.

Version Notes

Windows Phone

 It is recommended to not use VideoSink (with ARBG format) if you intend to save the video to a file by collecting video data to a buffer and writing your own encoder. Use FileSink instead.

If you want to save video capture to an MP4 file in order to play back at a later time, it is recommended to use FileSink.

Windows Phone OS

Supported in: 8.1, 8.0, 7.1
