2018-12-19Add support for bluetooth telephonyguppy_6.99.3guppy/6.99.36.99.3Thierry Bultel1-24/+50
This adds support for bluetooth telephony. A big rework in the softmixer internals has been mandatory, in order to support dynamic streams creation and deletions. Bluetooth telephony relies on the recent evolutions of bluez-alsa, the most important one being the support of HFP over Ofono. The softmixer opens PCM ioplugs provided by bluez-alsa. Bluetooth SCO needs 2 streams, one for listening and the other for talking. These streams are created upon requests sent by the hal-manager. The hal manager subscribes for bluez-alsa events and request the list of availalble transports. For each "attach" transaction verb, the softmixer maintains a list of the all created objects (sources, sinks, zones, ramps, streams, and more) Additionnally, it creates a new verb when the attach succeeds, that verb is typically something like "sco_XX:XX:XX:XX:XX:XX", and the only supported action at the present time is {"action":"remove"}, that performs all the cleanup of the registered objects.
