DirectShow filter - File association

We have directshow filter that implements CAsyncStream BaseClasses to encode buffer during playing our content. It's usual dll that is registered in system with regsvr32 command. We want that this filter will be associated with usual audio/video extensions and to be called other players when playing the files with like extensions. We found the way to associate our filter with avi extension. We set some settings in registry and our filter is called when some players (WMP, WinAmp) play the files with avi extension. But the same doesn't work for WMV and MP3 extensions. Especially we need to get it worked for mp3. So we need the right settings in registry that our filter was called by other players for files with WMV and/or MP3 extensions. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
