Revision 26, 2.9 kB (checked in by pieterpalmers, 19 years ago)

- Added subunit abstraction classes
- Implemented Audio & Music subunit detection in the AvDevice?
- Changed the debugPrint routine to be able to control debug output more granulary:

Debug output is now printed based upon the presence of a certain bit-flag.

- Various fixes

  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
