[UWP]捕捉元素文字叠加 [英] [UWP]Capture element text overlay

问题描述

是否可以通过捕获元素将文本叠加到实时视频流上？

解决方案

对UWP或者UWP一无所知Capture Element我确实找到了这个帖子
从CaptureElement& ;;执行实时视频流处理MediaCapture  在帖子中提及
"更好的方法可能是使用MediaCapture.AddEffectAsync（）并用C ++写一个Media Foundation Transform（MFT）处理视频并以某种方式将结果传回给应用程序。"。

所以也许您可以找到C＃中使用的Media Foundation Transform做你想要的

"媒体基础转换C＃"的Google搜索结果显示了一些可能的结果。我没有搜索VB的可能性。我真的不知道MediaCapture.AddEffectAsync是什么。但是如果C＃实现看起来很有希望，那么
可以使用 Telerik 来尝试将其转换为VB。净也许。

我猜你想在保存到某种视频文件的流上覆盖文本，所以重播它就会有文本。

Is it possible to overlay text onto a live video stream via a capture element?

解决方案

Well not knowing anything about UWP or Capture Element I did find this thread Perform live video stream processing from CaptureElement & MediaCapture which mentions in a post "The better way to do it would probably be to use MediaCapture.AddEffectAsync() and write a Media Foundation Transform (MFT) in C++ that would process the video and somehow communicate the results back to the app.".

So perhaps you may be able to find a Media Foundation Transform that is used in C# which can do what you want as Google search results for "media foundation transform C#" turned up some possible results. I did not search for VB possibilities. And I don't really know what MediaCapture.AddEffectAsync is. But if a C# implementation seems promising then you could use Telerik to attempt conversion of it to VB.Net maybe.

I'm guessing you want to overlay text on a stream being saved to some sort of video file so replayed it will have the text on it.
