Hi I am programming a simple movie player with DirectShow now. Everything seems OK, the only thing I haven't been able to do is to change the movie resolution on the fly (for example, I want user to be able to specify, when the movie is running, whether they want to zoom in or zoom out, etc.) Could someone point me in the right direction on how to do this? Thanks!
