使用C#的Media Foundation [英] Media Foundation with C#
问题描述
媒体基础是Microsoft推荐的技术，它通过许多示例和说明确实支持了该技术，但是所有这些都使用本机代码
Media foundation is the recommended technology by Microsoft and it has really supported it by a lot of samples and explanation but all are with the native code
我在 sourceforge 中发现了一个包装器，使我能够将Media Foundation与C#一起使用，但是在我读人们谈论的问题时，并不是所有事情都可以由托管代码来完成
I found a wrapper in sourceforge make me able to use Media Foundation with C# but while I am reading people talk about not every thing can be done by the managed code
我有一些与MF有关的任务:
I have some tasks to do with MF:
- 捕获实时视频
- 更改分辨率和波特率
- 编码视频
- 解码视频
我可以在这些任务中使用.net还是必须使用本机代码?是否有示例帮助(请不要从其中提及msdn)?
Can I use .net in these tasks or I have to use the native code?Is there samples help (please don't mention msdn one from them)?
推荐答案
Media Foundation .NET C#包装程序可以很好地完成您提到的所有任务.我已经亲自使用它来实现捕获，调整大小和编码，而且我想解码也不应该太难.
The Media Foundation .NET C# wrapper can work well for all those tasks you mentioned. I've used it personally to implement the capture, resizing, and encoding, and I imagine decoding shouldn't be too hard either.
该项目确实提供了一些示例，您可以下载，但我发现它们相当缺乏.包装程序非常接近C ++实现，因此使用C ++示例并不难，只需将逻辑移植到C#.我使用以下内容作为参考，发现它非常有价值: https://github.com/sipsorcery/mediafoundationsamples
The project does have some examples you can download but I find them rather lacking. The wrapper is so close to the C++ implementation that it's not too hard to use C++ examples and just port the logic to C#. I used the following as a reference and found it to be very valuable: https://github.com/sipsorcery/mediafoundationsamples
