I need an mp3 decoder, for windows and mac os x, I own IPP 6, but it seems that UMC has been deprecated (??) and is not available for OSX 64-bit, so the alternative is "Media SDK", but:
"Media SDK for Windows* - A cross-platform API for developing media apps (foundation)." - What on earth is that? Is it crossplatform then or is it not? Is it available for OSX 32 & 64?
