Commit Message

Iulia Tanasescu Nov. 15, 2024, 10:38 a.m. UTC
This makes BAP parse_base public, so other plugins can reuse the logic
(BASS should also parse BASE internally for the Scan Delegator
implementation).

Since different plugins need to handle BISes differently, this commit
also reworks parse_base to receive a BIS handler callback which will be
called for each parsed BIS.

Hi Iulia,

For this sort of dependency should be handled by shared libraries,
otherwise we create interdependencies of plugins.

The idea itself is good though, but I suggest we put this under
shared/bap.h, also it would be great to create some unit tests for it,
perhaps one test per supported AC or something like that, anyway this
can be added later on a separate set.
