How to detect if DRM is set in WMA
-
Not sure if this is the right forum for this, but I need to determine whether a given .wma file has DRM set in it or not. I'm working on a project that uses a 3rd party tool to burn CD's, and they have told us that these types of files are not supported, so I need to weed them out before they get there. I've been digging around MSDN pretty much all morning, and keep going in circles, not really finding anything out. Most of the DRM articles talk about encoding the file to begin with, not what to do after. The only one thing I found about after the fact was this little not to promising tidbit: "The actual mechanics of DRM take place through low-level functions in the operating system. As a result, higher level APIs, such as DirectShow, and the applications built on top of them, such as Windows Media Player, have little opportunity interact directly with DRM." Any ideas? There must be some way of detecting it. ----- In the land of the blind, the one eyed man is king.
