Incoming connections only happen when the remote end is an AG.
Advertising the state allows the device to dynamically create nodes
for such connections.
errno should be set to the positive errno value.
This does not cause problems except for the pulse-server where the
errno value is negated and returned as an error result.
Typically a source stops the connection when it has nothing to play
and this causes the transport to become "idle" and our A2DP source
also stops. However, the node is still present and "running" (if linked),
which causes the graph to underrun as it receives no data from this node.
This patch dynamically creates and destroys the a2dp source node depending
on the transport state. So, when the transport is idle, there is no node
in the graph at all.
SCO transports have timer-delayed release, but they need to be released
immediately when changing profiles to close connections before switching
to A2DP.
Mark bluez5 routes always available in EnumRoute, because there's always
a device connected.
Fixes default-route resetting profiles back, when they are manually
changed.
This does not work as intended, because we no longer do a codec switch
on device connect. It should be done in a different way, but since it's
not used for anything right now, can as well remove it.
This may avoid infinite loops if parameters are being set based on events
sent by parameter changes. It's also what alsa-acp devices do, so bluez5
should follow.
This will prevent to run the different backends concurrently.
The native backend will only register to BlueZ if neither oFono nor
hsphfpd are running. If one of them starts, the native backend will be
unregistered and the corresponding backend will register to its daemon.
Make queueing a codec switch work properly. When receiving the dbus
reply, it should move to latest one. Others should be discarded.
Previously, it instead hit an assert, if there were more than two
queued.
Not all devices report their A2DP delay. In those cases, use a fallback
value of 150ms by default.
Make the delay adjustable with a SPA_Prop, and expose it as a part of
the route. Implement the corresponding parts in media-session.
In BT_DEFER_SETUP mode, when a connection is accepted, the listening
socket is unblocked but the effective connection setup happens only on
first receive, allowing to configure the accepted socket.
First read from the accepted socket is non-blocking and returns a zero
length buffer.
