Question

我希望用户插入视频的直接链接，例如http://www.video.com/test.mp4

单击“提交”按钮后，您将查阅MICROSOFT VIDEO API JSON并获取此信息。

我能够为图像创建一个，我将在这里提供代码，但是我在为视频创建时遇到了很多麻烦。

我还想知道我是否可以通过“直播流”获取此信息，例如IP在线相机的示例。

我还想知道我是否可以通过“直播流”获取此信息，例如IP在线相机的示例。

根据Video API的文件，如果我们提交视频链接。视频将上传到服务进行分析。它不适合直播。

如果您想实时分析视频，则需要从客户端的视频中捕获帧并逐帧分析视频。以下是使用C＃的Live Camera的代码示例。

如何使用Microsoft Video API？
