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
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
Add a default.clock.allowed-rates property that lists the possible
rates for the graph.
Add node.rate and node.lock-rate properties to suggest a graph rate
and lock the rate.
Collect the largest clock rate from the nodes and if it is allowed,
try to configure it as the graph rate. Only switch rates when the
driver is IDLE or suspended or when we force a rate.
No alternative samplerates are specified because we first need to
work around a common driver bug (cards with 1 cristal need the same
rate for capture as playback) for this to work.
200ms seems a little small, some plugins initialize themselves from the
RT thread and get killed. 2 seconds seem to be a better default.
The important part is that there is a limit so that runaway processes
are killed and don't lock up the system.
Fixes#1344
This allows building wireplumber as part of the pipewire build
and running it in the uninstalled environment instead of media-session.
Building each session manager is individually contolled by the options:
-Dmedia-session=auto/enabled/disabled
-Dwireplumber=auto/enabled/disabled
And controlling which one is used in pipewire.conf is done with:
-Dsession-manager=media-session/wireplumber
Wireplumber's source tree must be in subprojects/wireplumber/
If this is missing, the .wrap file ensures that the latest git
master is downloaded while meson configures the build.
This git tree will not be automatically updated later, you need
to ensure that it is up-to-date on your own.
Add new context config clock.power-of-two-quantum to make it possible to
not round quantum to closest lower power of two. This makes it possible
to match the quantum of a source node with the quantum of a client
node.
Make arrays from config sections that should really be an array.
Having the module name as the object key technically makes it
impossible to load the same module twice because the key can only
be once in the object.
The same applies to the context.objects and context.exec sections.
This also makes it somewhat easier to parse the config..
When running pipewire as a system-wide daemon, module-portal
obviously doesn't load. Make it optional so that the default
config doesn't fail in system-wide mode
Add -c option to pipewire to select config file. Use this to select
the uninstalled conf file.
Rename conf properties, prefix with context.
Simplify the main daemon now that everything can go in config.
Simplify pipewire-pulse now that we can put everything in config, it's
now virtually the same as pipewire but with a differenct config file.
Parse server addresses as array of strings.
Use spaces instead of tabs (as they depend on text editor settings).
Make configuration files more readable and consistent seeing as there
were some mixed indentation and styling.
Also put some logic into styling.
