Hello, I'm looking at using Windows Media Foundation in our application for creating H.264 MP4 media files. Can you provide some guidance on how to capture screen video/audio? The screen content will include standard windows screens as well as Flash/Silverlight content and I'd like to achive a frame rate of about 20fps. (An example of how to configure the source would be fantastic)

推荐答案

媒体基金会中没有屏幕截图源.如果要在MF中进行屏幕捕获，则需要编写自己的源代码.将原始帧放入MF管道后，MF确实具有屏幕编码器.

There is no screen caputre source in media foundation.  If you want to do screen capture in MF, you would need to write your own source.  MF does have a screen encoder, once you get the raw frames into the MF pipeline.
