The bluetooth backend of base system virtual_oss has a HAVE_LIBAV ifdef,src commit FILLME ("virtual_oss: Port to base") includes the bluetooth
which enables AAC audio support.backend, however the backend also has a HAVE_LIBAV ifdef, Howeverwhich, because this code depends onif set,
libav (multimedia/gstreamer1-enables libav), we need to build it as a support., Itwhich depends on multimedia/gstreamer1-libav.
essentially recompiles the bluetooth backend but with HAVE_LIBAV setWhile we could build the non-libav parts from base and the libav ones as
a port, we instead build the whole backend as a port to avoid
unnecessary complexity. The reason for that being that building from
base would install the backend in /usr/lib/virtual_oss/voss_bt.so, and
the port would install _another_ voss_bt.so, but this time in
/usr/local/lib/virtual_oss/voss_bt.so, which would create conflicts.
The port simply builds the files from src, which is not ideal, as this
means that the src repo needs to be present in the system in order for
the port to build, but this way we can avoid version mismatches and
ifdef hell as the project progresses.
Note that this is an extension for the base system virtual_oss, and not
audio/virtual_oss.
