The Dbus device reservation has been moved into a separate module, and has also
been refactored to allow reserving a device name before an actual device is
created. Devices now are created and destroyed by the monitor depending on
whether PipeWire owns the device or not. This also simplifies a lot the device
activation module to always enable devices when they are created, and never
worry about checking whether a device is acquired by PipeWire or not.
there are underlying issues with the state management of the graph,
so it's not a very good idea to rely on it to activate / deactivate
our convert node depending on the links that exist
instead, track the links ourselves and create/destroy the corresponding
links to the target node accordingly; it's a more robust approach
it was also not entirely correct that we would previously configure
the convert node to be a driver (node.driver=true); maybe this caused
the underlying issues in the first place... we don't need it now
anyway, so it's gone
1. device export proxies must be destroyed manually since they are
not associated with the WpRegistry
2. the monitors should not disconnect before all WpSpaDevice objects
are destroyed; remove the manual disconnect call and let GObject
ref counting do its job (the core will disconnect when its last ref
count is dropped after the last monitor plugin is destroyed)
* do not copy the full alsa node properties set
* use a node description that makes the nodes look better in JACK
* use . instead of / as a separator for the node.name, like elsewhere
* add audio.convert spa lib association in the tests that use si-convert;
previously it used to work because library.name was present in the
properties copied from the adapter (and it so happens that the adapter
lives in the audioconvert spa plugin as well ...)
previously, we would only remove the endpoint associated with
the node, but not the monitor endpoint...
to implement that, we now store the node's associated session items
in the node's qdata instead of a local hash table, so that we
can store an arbitrary ammount of session items per node
In case we have a multi-channel capture device and a mono client,
treat the MONO port as UNKNOWN and let it link with the first
port available on the device
Easy to test with arecord, which by default captures in MONO
this allows slightly easier testing while every client uses node.target
but it's easier to find the endpoint id than the node id
through `wpctl status`
We have multiple instances of the monitor plugin, but that's ok.
connect/disonnect will not do anything bad if called multiple times
We need to connect later so that the first connection is the one from main().
Otherwise, if there is a connection error, we will see the warning from the
monitor first.
