Changeset 21

Timestamp:

11/24/04 14:13:21 (19 years ago)

Author:

pieterpalmers

Message:

- Fixed some bugs in AvDescriptor? and AvDevice?
- Added more tests of the new classes to ieee1394service
- Modified the debuglevel to hide low level AVC transactions by AvDevice?
- Added AvMusicIdentifierDescriptor? and AvMusicStatusDescriptor? as a first

attempt at parsing device info.

- Added AvInfoBlock? to handle infoblocks (still very embryonal)
