打开闪光灯。有没有办法通过使用MediaCapture类来做到这一点？谢谢！

I have a Lumia 1020 with WP8.1 dev preview. In Nokia Camera, the flash could be turned on (like a flash light) during video recording. But looks like MediaCapture class doesn't support that. I tried the following code during video recording. But it doesn't turn on the flash during video recording. Is there a way to do that by using MediaCapture class? Thanks!

this._mediaCapture.VideoDeviceController.FlashControl.Enabled = true;
this._mediaCapture.VideoDeviceController.FlashControl.Auto = false;

解决方案

You will need to use the torch control: http://msdn.microsoft.com/en-us/library/windows/apps/windows.media.devices.videodevicecontroller.torchcontrol.aspx
