I am using WPF application which is using DirectShow library and it is working fine for grabbing images or recording the live feed,but i wants that end user should not be able to see that any web cam is taking their picture i.e. i wants picture box or panel which is rendering the feed from the webcam should not be visible to the user and i should be able to capture the images or record the live feed.

推荐答案

DirectShow不需要任何可视组件即可捕获快照或视频。

DirectShow does not need any visual component to grab snapshots or video. It is just one of the popular methods to display video live and grabs snapshots off the video presenter.

请继续使用Sample Grabber捕获帧，然后 DxSnap 示例向您展示了如何操作。

Read on using Sample Grabber to capture frames, and DxSnap sample from DirectShow.NET shows you how.

使用DirectShow从静态引脚的快照捕获
设备。请注意，MS鼓励您为此使用WIA，但是如果您想在DirectShow和C＃中使用WIA，请按以下步骤操作。

Use DirectShow to take snapshots from the Still pin of a capture device. Note the MS encourages you to use WIA for this, but if you want to do in with DirectShow and C#, here's how.

请注意，此示例仅适用于将
未压缩视频输出为RBG24的设备。这将包括大多数网络摄像头，但
可能是零电视调谐器。

Note that this sample will only work with devices that output uncompressed video as RBG24. This will include most webcams, but probably zero tv tuners.
