How to grab constant stream of bitmap images from webcam in c#

We have ac# application that performs processing on video streams. This is a low-level application that receives each frame in Bitmap format, so basically we need 25 images each second.

So we basically need to capture bitmap images from a webcam continuously so that we can pa

如何从C#中的网络摄像头抓取位图图像的恒定流

我们有一个ac#应用程序,用于处理视频流。 这是一个以Bitmap格式接收每帧的低级应用程序,因此基本上我们每秒需要25个图像。 这个应用程序已经在为我们的一些媒体资源工作,但我们现在需要添加一个网络摄像头作为输入设备。 所以我们基本上需要不断地从网络摄像头捕获位图图像,以便我们可以将所有这些帧作为“流”传递给我们的应用程序。 访问摄像头并直接从网络摄像头读取实际帧作为单独图像的最佳和最简单的方法是什么?
