我正在使用Microsoft 此处.我想更改在我的应用中录制的视频的分辨率.当前，默认情况下以最高分辨率录制.怎么做?

I am using the video recording sample provided by microsoft here. I want to change the resolution of the video being recorded in my app. Currently its recording in highest resolution by default. How to do so?

推荐答案

AudioVideoCaptureDevice.OpenAsync的第二个参数是分辨率.您可以使用AudioVideoCaptureDevice.GetAvailableCaptureResolutions(sensor)获得分辨率.

Second parameter for AudioVideoCaptureDevice.OpenAsync is the resolution. And you can get the resolutions using AudioVideoCaptureDevice.GetAvailableCaptureResolutions(sensor).
