Add an option to do a hilbert transform on the generated rear channels
to do a 90 degree pahse shift on them. This can improve spacialization
of the rear channels.
See #861
Use invoke to set the zero-denormals flag from the data thread when
explicitly set. The flag is per thread and should really only be set on
the data thread and only when explicitly enabled.
Fixes#2160
Add a module for a fallback dummy sink, which appears dynamically when
no other sinks are present.
Enable it for pipewire-pulse, because Pulseaudio will also show
dynamically a dummy sink.
As soon as a JACK app is started, the automatic quantum change is
disabled. This means no pulse/alsa app can change the quantum.
The only way to change the quantum is with node.force-quantum or
with the settings metadata.
This means only a JACK buffersize change (usually controlled from the
JACK app, such as in ardour) or a metadata change (from the command
line) can modify things. Both of those are usually caused by a user
action.
For JACK apps where the quantum is allowed to change automatically,
explicit rules need to be placed in the config.
Since meson 0.59.0, a feature object has an `allowed()`
method which returns true when the feature is set to
'enabled' or 'auto'.
Utilize that instead of the previously used
not feature.disabled()
This automatically configures the node in a supported format with the
highest amount of channels. Options are available to enable monitor
and to override the port channels as AUX or UNKNOWN.
Add an option to check if the rate and quantum configured with the
settings metadata is in the allowed range.
This is false by default, you can use metadata to set any rate/quantum
but in a minimal controlled setup you might want to restrict this.
Make the default nice.level an invalid value, that is not configured
as the priority on a process.
Explicitly enable a nice level on our daemon processes.
Fixes#2034
Since 01c6fd0a88 the
minimum required meson version is 0.59.0, and since
meson 0.58.0, `get_variable()` on a dependency object
accepts a positional argument. The "type" of variable
(internal, pkgconfig, etc.) in that case does not need
to be specified explicitly.
I don't think PipeWire currently has a way to temporarily alias
module-rtkit to module-rt though, so right now this would break realtime
scheduling for people with modified configs that use module-rtkit.
Allow an app to request up to 2048/48000 quantum. This will be scaled
with the selected sample rate so if the graph changes to 96000, the
quantum will be scaled to 4096. It will scale up to the hard limit of
quantum_limit.
See #1931
Also scale the max_quantum with the selected rate. Add a new
quantum_limit property that is the upper limit of the quantum regardless
of the sample rate, this is usually the allocated buffer size.
See #1931
Extend the server.address property so that you can also specify
an object per server. Add support for configuring some aspects of the
server such as max-clients and backlog.
Most importantly, the pipewire client.access can be configured per
server.
See #1960
Use `meson.project_{build,source}_root()` instead of
`meson.{build,source}_root()` because those functions
do not work as expected when used inside a subproject,
and they have been deprecated in meson 0.56.0.
Let's add PipeWire and Socket into the description, the current messages
are not overly obvious:
Listening on Multimedia System.
Closing Multimedia System.
Add a jack.show-monitor option (default true) that makes it possible
to hide the monitor ports.
Monitor ports are not enabled by default on JACK and maybe they also
should not for PipeWire. Or maybe we need some tweaks for some apps.
See #1760
In Meson, string.contains() is a substring check but array.contains() is
a full string check. Let's use 'foo in bar' style instead to avoid
confusion.
Supported since meson 0.49.0
Both wireplumber and media-session have a meson variable now that
represents the -uninstalled script, complete with filled-in BUILDDIR
etc.
Let's use those variables for pipewire-uninstalled.conf so we don't have
to fill in the paths here.
If we build media-session before the daemon we have the executable
variable available and can rely on meson to fill in the path instead of
handling it manually.
There are only two values we care about that are identical, we can
re-set those in a new configuration_data() object.
All the other values set by the pipewire daemon are related to how we
start the session manager which isn't applicable here.
Add a method to enable/disable the denormals flush-to-zero and
denormals-as-zero CPU options.
Add a config option to make it possible to disable this again.
Fixes high CPU usage when dealing with denormals, which can happen
in many DSP functions.
Fixes#1681
