This allows loading objects on demand by adding entries on the
"sm-objects" metadata object.
It is useful to dynamically load pipewire modules such as loopbacks
or network modules without having to start a new pipewire process with
a hardcoded config file.
It is also useful to load new metadata objects in order to implement
the singleton metatada concept as discussed in pipewire!1742
This may be expanded in the future to be able to load other types of
objects.
The key name, combined with the subject, is considered a unique id for
this instance of the object. The value should be a json object with
a 'type' specifying the type of object, together with a 'name' and 'args'
While handling endpoints, first check to see if there is a filter
intending to connect to it.
Also prevent Endpoints connecting to filters unless otherwise
configured.
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.
This is a behavioural change in effect since pipewire 0.3.68, where
pipewire's link-factory ignores the link.passive property and the
node.pasive = in/out/true is used instead.
Sometimes, it may be necessary to pass arguments in to a
Pipewire module being loaded. Allow this to be done using
the same format as load_module()/load_optional_module().

update the module-rt description and commented-out defaults to
reflect the addition of utilisation clamping to the module.

some hardware devices are never supposed to be accessed directly by
clients, and are designed under the assumption that they will be
front-loaded by some sort of DSP. add a hide_parent property
to policy-dsp and revoke all permissions to the bound node of a DSP
graph where this is set to prevent hardware misuse or damage by poorly
behaved/configured clients.

Disable bluez5.auto-connect.
It makes PW to try connect to all locally known BT audio devices on
start, which is in general not a good thing to do.
Some BT adapters are not capable of simultaneous audio streaming and
scanning for connections (e.g Raspberry Pi builtin BT, probably more),
so audio stutters until adapter/kernel give up trying to connect to
devices that cannot be reached.
Disabling it makes devices to not reconnect on user VT switch, but also
that we should only do for devices that were connected when logind
switched.
After a timeout, it's possible that something else may have
destroyed the node already. This can happen for example with virtual
sinks that were created from another process.
Fixes: #467
libcamera uses namespaces to sandbox IPA (Image Processing Algorithm)
modules because they are sometimes proprietary binary blobs. The
RestrictNamespaces option in Wireplumber's systemd service breaks this
sandboxing when libcamera is loaded via the libcamera SPA module, so
cameras requiring an IPA do not work.
This commit removes RestrictNamespaces so that the sandboxing works
again. I've confirmed that after this change wireplumber works with
libcamera with an IPA module.
Resolves#466
For Bluetooth LE Audio device sets (e.g. pair of earbuds), bluez5-device
emits "internal" nodes for each individual device, and a combine node
for the device set.
Make the bluetooth monitor to create the combine nodes using
module-combine-stream.
Do some shenanigans to route ObjectConfig events from bluez5-device to
the correct combine node: look for combine nodes associated with device
sets, and put them as managed objects of the Spa devices.
Add support for BLE MIDI devices and local endpoints.
Disabled by default for now, as the feature currently faces some
DBus/SELinux policy issues e.g. on Fedora.
For offload SCO, the audio stream should be routed to/from Bluetooth
chipset via ALSA.
To do this, this commit prevent the creation of the sco-source or sco-sink
nodes, and replace them by loopback nodes.
It's up to the platform to correctly the the route to the Bluetooth chipset
ALSA entries.
When the loopback node state change to running, the script also call the
bluetoothOffloadActive param of the device to start/stop the SCO link.
This adds three meson options to enable or disable building daemon, tools, and modules.
Building the daemon or tools depends on building the modules, and disabling modules without disabling
the other two will result in meson giving an appropriate error.
These new options will let users skip building and installing unneeded items when they are not needed,
e.g. when only using the C API in another application.
When a plugin activation fails, it is supposed to fail the wireplumber init. To
be precise it fails the wp init transition and the init transition objected is
freed.
However the subsequent plugins added(as reported by the plugin object manager)
trigger double free, prevent this by avoiding calling the activation callback
after the transition object is freed.
When a new camera is added, go over all clients and update the
permissions for the new camera.
This makes it possible to plug in a new camera and make it visible to
the portal apps.
entities here are the device cards and the device nodes.
sometimes null device objects are reported by monitor, this results in lua
exceptions handle this use case.
