* find out if the node supports iec958 or dsd
* use spa_pod_fixate() to get the default format of the node, like p-m-s does
* use _enum_formats_sync() to utilize the param cache, assuming that the node
always has all features enabled (which is always the case when coming from
an ObjectManager that was defined in Lua)
* simplify the activation / deactivation procedure
* configure nodes with unpositioned channels early, as if they were devices
* 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
Using XDG_RUNTIME_DIR is problematic in test-reserve-device
because GTestDBus also exports XDG_RUNTIME_DIR and then unsets it,
which makes pipewire end up using $HOME for its socket.
Using PIPEWIRE_RUNTIME_DIR is safer, as this variable is only used
by pipewire.
Also use the build directory as a runtime dir (it always exists and
nothing is going to interfere with it) and unset XDG_RUNTIME_DIR from
the CI scripts, since nothing else is using it.
Closes#39
Until now, object manager could only match pw global properties on
pw global objects, because this is the only available properties set
at the time the registry creates the global.
With this change, the object manager will now bind the proxy
if the type and the pw global properties have matched and will wait
until the proxy is available with all of its properties and tries
the check again.
There is no real use for groups in our API. Just use the name of
the file as the default group and be done with it...
Storing multiple groups with this API is problematic because it
forces flushing the file to disk multiple times, one for each group,
and it's just more performant if we use a prefix in the keys
to implement some form of logical separation.
This commit also makes the GKeyFile a temporary object. As we
always load the file from the file system in _load()
and we always replace its contents with a new dictionary in _save(),
there is no point in keeping the keyfile's internal data structures
stored in memory.
Save errors are now also propagated to adhere to the programming
practices of GObject
- use si-audio-adapter, to keep the original test's spirit
of linking two terminal nodes, not two intermediate ones
- setup null sink to be a virtual device sink with 2 channels
and the audiotestsrc to be a stream, so that it is also configured
to have 2 channels via si-standard-link's logic
- don't use a second client core, as it introduces races;
we don't need that anymore because we don't export endpoint-links
