I've been a software developer for almost 15 years now and I've been programming with DirectShow/DirectX in C# for almost 2 years. My company streams video from cameras and we are using DirectShow/DirectX technology to do so.
My ability to download samples off the internet and implement them into our application has worked fine so far, but we are beginning to grow in functional need and I really have to get my teeth into DirectX programming. Does anybody have any books they would suggest for me to start off with? Again, i'm not gaming, i'm streaming video from video capture cards and USB cameras.
Also, is C# sufficient for DirectX programming, or would it be worth my while to learn C++ (something I've never used).
