How to capture video out of stream in c/c++ in windows?

What's the most recommended 开发者_开发百科way to go?

This is a pretty big topic. Try looking at OpenCV. It is nice for image and video manipulation, and you can stream video from files and webcams.

Take a look at DirectX "Filter Graphs". You can use a simple tool from the DirectX SDK called 'Graph Edit' to construct a sequence of DirectShow Filters which can do things like capture video streams from a TV card or decode an MPEG/AVI file and then operate on the data stream and ultimately render it to video/audio or a file.

Most of the DirectShow samples are in VC++.
