Equalizer Node or filter nodes are considered as regular linkable and
its output is connected to endpoint. Prevent this by skipping over
filter nodes in this script.
Policies need to know if there are session items that are pending
activation. Linkables are not activated in the same order as nodes
appear, which causes problems for e.g. resolving target nodes, if some
of the linkables are pending.
Register linkables in create-items before they are activated. When
activation completes, remove those that did not activate successfully.
Policies can filter out inactive items by tracking active-features
flags.
If there are existing linkables that are not ready, suspend policy-node
processing, and continue it only after all linkables are ready.
If a stream audio node does not have the 'media.role' property set, the policy
will asign the 'Default' media role name to it. In addition to this, if the
'Default' endpoint can not be found, the policy will link the stream audio node
with the lowest priority endpoint.
Video nodes will always be handled by policy-node.lua, and they will never be
handled by policy-endpoint-client.lua
This allows users to assign a particular endpoint for streams that don't have
the 'media.role' property set.
The Role traversal of config data to take notice of the
media class as well so that source and sink roles dont
overstep on each other and pick up unexpected endpoints.
* populate most session item properties from create-item.lua to keep
things more compact and readable
* use a standard naming scheme for the session item properties
* use session item properties instead of node properties in policy-node.lua
* improve policy-node's performance by converting the properties dictionary
less times for each session item
* refactor some policy logic and make things slighly more readable
* change the accepted values for 'context' in wp_si_linkable_get_ports();
use "input" and "output" to keep things clear, because the previous use
of NULL and "reverse" were implying that a node has only one "standard"
direction, but this is complicated for sinks w/ monitors and duplex nodes
* allow using monitors (which are Audio/Sink nodes in fact) as sources
* treat Audio/Duplex nodes as sinks, like p-m-s does
* respect the "stream.capture.sink" property of streams
Fixes#66
- sanitize printing properties with tostring(), which will properly
convert nil values to the string "nil"
- ensure some properties become empty strings if they are nil
Allows relinking client nodes to other devices if the current device has been
removed. This allows audio to keep playing in a different device if a bluetooth
device is disconnected.
The policy scripts can handle now client nodes that want to be linked with other
client nodes. This is needed for nodes created by the Pulse Audio Volume Control
to monitor audio comming from other application client nodes.
These don't make much sense here. In the endpoint policy we want
the clients to be linked to the endpoint that matches their role
and never move.
Also, endpoint priorities are useless. If no endpoint matches the
role, then just ignore the client.
