将视频显示为DirectX纹理 [英] Display video as DirectX texture

问题描述

我想在DirectX纹理上显示视频帧(以前使用Windows Phone 8摄像机录制；不是实时预览，而是录制的视频文件).是否有方法(在C#或C ++中)从压缩的文件中获取原始图像数据(作为RGB) 视频流(MP4，H264)?

I want to display the video frames (recorded previously with Windows Phone 8 camera; I do not mean the live preview but the recorded video file) on a DirectX texture. Are there means (either in C# or C++) to get the raw image data (as RGB) from the compressed video stream (MP4, H264)?

对于Windows RT，有一个类似的项目，但WP 8不支持该项目:http://code.msdn.microsoft.com/windowsapps/Media-Engine-Playback-ce1c82f0/

There is a similar project for Windows RT but it's not supported on WP 8: http://code.msdn.microsoft.com/windowsapps/Media-Engine-Playback-ce1c82f0/
