Windows Media Foundation使用原始图像对视频进行编码

Question

I'm working on a project that requires me to record webcam, microphone, and the screen. I have webcam recording, audio is a work in progress , and I stumbled across CMonitor wrapper (which I did some minor modifications to) to grab RGB images of the desktop on a specified monitor (if there are multiple monitors).

How do I go about pushing my raw RGB frames into windows media foundation to encode into a video file? My current video encoding is using a slightly modified version of this msdn sample , if that's easier to modify than it is to write a new class handler.

Or, perhaps there is some sort of media foundation route to recording the screen that I don't know of (which is possible, I'm not that great of a win32 programmer)?

Answer 1

在Windows SDK示例中找到了PushSource。

Answer 2

Check Desktop Duplication API for capture desktop. Media Foundation provides two solution for encoding, MF Sink Writer for simple encoding, Media Session for a more flexible control of the media pipeline. Read this overview page first.
