      We currently have two multimedia backends on desktop Windows: DirectShow and WMF.

      • WMF is used with MSVC on Windows Vista and later
      • DirectShow is used on Windows XP with all compilers and on other versions with MinGW

      We should use only one backend for all versions of Windows and with all compilers in order to ease maintenance. DirectShow also has the advantage of having better codec support.

      Some missing features need to be implemented to be on par with the WMF backend and to not brake existing apps.
