UWP获取实时网络摄像头视频流
[英]UWP get live webcam video stream
问题描述
I was looking into the MediaCapture class, however it doesn't seem to expose what I'm looking for. 
我正在调查MediaCapture类，但它似乎没有揭示我正在寻找的东西。 I want the live Stream from the web cam - not to record it or preview it. 我想活Stream从网络摄像头-不记录，或预览。 I'm working on the Microsoft Cognitive Services Emotion API and I want to follow this example , but instead of getting a local video stream from the file system - I want to get a Stream from a web cam. 我正在研究Microsoft Cognitive Services Emotion API ，我想要遵循这个示例 ，但不是从文件系统获取本地视频流 - 我想从网络摄像头获取Stream 。

The Microsoft Cognitive Services Video APIs, including Emotion, are REST APIs, not streaming APIs, so your scenario is not supported. Microsoft认知服务视频API（包括Emotion）是REST API，而不是流API，因此不支持您的方案。
What you can do instead is periodically capture a frame and make RESTful calls to one of the image APIs. 你可以做的是定期捕获一个帧并对其中一个图像API进行RESTful调用。
