Move all the media-session object monitoring into one place and
provide an API to get to the session objects.
Make API to add module specific info to objects.
Add methods to export and create objects in the session. This should
make it possible to link proxy to implementation and avoid a server
roundtrip in some cases.
pulseaudio card is mapped to device
pulseaudio sink/source is mapped to an endpoint
prepare to map streams to card profiles
Add Route param to implement the endpoint routing later (ports)
Create an alsa endpoint for each device
Create one stream for each endpoint (Playback/Capture)
Implement create_link on the endpoint. The idea is to call
create link on the peer endpoint to complete the link. Remove
create_link on the session.
Add stream-monitor to turn pw_stream nodes into endpoints
Add a policy manager that tries to link endpoints
Use enum pw_direction for the endpoint direction. We can use the
media_class to determine if this is a pw_stream or not but it should
not really matter, you can link any output to any input.
Add autoconnect property for endpoints to make the policy connect.
Separate the session manager in a monitor and policy part.
The monitor manages the devices and endpoints.
The policy watches the nodes/ports/clients and applies the policy
of linking them.
Because both now have a separate connection, we can remove some
hacks in the protocol. When a remote was both the implementer and
user of an object we could get in a deadlock when the user was
blocked waiting and the implementator was blocked sending a reply.
We used to un-busy a client when it was expecting a reply from a
ping or sync for this reason.
Add and use some more keys for the endpoints and streams.
Metadata allows apps to attach properties to objects that can be
read by other apps.
Not complete yet, properties should be removed when the object is
removed.
Change node.priority to priority.session to indicate that this
is the priority that the session manager uses to select the node.
Add another priority.master that the core uses to select a master
driver. Keep the driver nodes sorted by master priority.
Let jack always prefer to connect to the master driver nodes.
Add a jack device and activate it when we release the device (for JACK
presumably). We need to work around some issues, jack does not allow
us to connect yet when it asks to release the device so we need to
wait a little and then connect.
Implement the device reservation DBus API.
When we acquire the device name, set our device profile to 'On'. This
adds our sources and sinks to the graph.
When we lose the name, switch back to 'Off' and remove our nodes
again.
Move the session mamager stuff in a directory.
