Hi. I''ve been using the OpenGL Game Programming book to design an engine. Based on the book, it suggests the use of DirectInput and DirectSound for input and sound. However, I discovered that DirectSound doesn''t seem to support mp3 format files (since I want to play music in my programs) and I feel that mp3s are a nice, compact format compared to wavs. Can anyone suggest what I should do? I noticed that in the DirectX 8.0 SDK that the DirectShow samples support mp3 playback. Unfortunately, the SDK help files was a little vague and the commenting, as you can probably imagine, is very sparse. Seeing as how I have a very bad understanding of DirectX, I was wondering if anyone could give me some help in this area?

Look into using the IGraphBuilder Interface. There''s a method called RenderFile that all you have to do is pass it a filename and it builds the graph needed to play that file back.

Thanks. This is just in the SDK documentation right?

Oh yeah, go easy on me, I''m very..VERY new to any directx.
