Revision 554, 2.4 kB (checked in by ppalmers, 13 years ago)

Merge echoaudio branch into trunk.

This adds support for the Echo Audiofire devices to FFADO. Possibly also other devices working with the Apple Class Driver will work with this code. It is not fully complete yet, but the main rework is
done.

First of all the IAvDevice class/interface is renamed to FFADODevice, in order to separate the AV/C code from the FFADO API code. A device supported by FFADO implements a FFADODevice.

The BeBoB device has been split up into three groups:
- libavc/* : all code and commands that are specified by AV/C specs. Note that a lot of the code that used to be in BeBoB::AvDevice? now resides in AVC::Unit
- genericavc/* : a FFADODevice that uses AV/C descriptors & commands for discovery and config
- bebob/* : the bebob FFADODevice that inherits from GenericAVC::AvDevice? but that uses BridgeCo? commands for discovery

Everything has been moved as high as possible in the class hierarchy. If necessary, a subclass that uses device specific commands is introduced (e.g. BeBoB::Plug inherits from AVC::Plug and uses the
BridgeCo? extended plug info command to discover it's properties).

There are some other fixes along the way that have been done too.
