I am developing a Windows Phone 8.1 app. 我正在开发Windows Phone 8.1应用程序。 Nokia provides fantastic Imaging SDK to apply filters to images. 诺基亚提供了出色的Imaging SDK，可将滤镜应用于图像。 I want to apply filter to a video file. 我想将过滤器应用于视频文件。 I searched about it & found Media Foundation Transform (MFT) . 我搜索了一下，发现找到Media Foundation Transform（MFT）。 MSDN provided a sample to apply grey scale filter to video. MSDN提供了一个将灰度滤镜应用于视频的示例。 It's totally based on C++. 它完全基于C ++。 I am totally unknown to C++. 我完全不了解C ++。

I think I would extract each frame of video, apply filter to each frame & rejoin them to make it a new video. 我想我会提取视频的每个帧，对每个帧应用过滤器，然后重新加入它们以使其成为新的视频。 What approach should I use to do that? 我应该使用哪种方法来做到这一点？

Is there any SDK/library available to extract frames? 是否有任何SDK /库可用于提取帧？ I have one off-topic question also, can I use any native C++ library in Windows Phone or it must be Windows Phone Runtime Component? 我也有一个题外的问题，我可以在Windows Phone中使用任何本机C ++库还是必须是Windows Phone运行时组件？
