Add a new build option 'system-user-unit=dir', which can be used to
override the pkg-config default value.
By doing this, it becomes more practical to make a local unprivileged
build of the latest PipeWire:
$ meson --prefix=~/.local build
$ meson configure build -Dpipewire-alsa=false
$ meson configure build -Dsystemd-user-unit-dir=~/.config/systemd/user
$ meson configure build -Dudevrulesdir="`mktemp -d`"
$ ninja -C build install
For a local build enabling ALSA plugins is not plausible.
JACK needs a simple addition to the ~/.profile:
export LD_LIBRARY_PATH=$HOME/.local/lib/x86_64-linux-gnu/pipewire-0.3/jack
Finally, the genuine PulseAudio must be masked and local services
enabled:
systemctl --user enable pipewire.socket
systemctl --user enable pipewire-pulse.socket
systemctl --user mask pulseaudio.service
A sanity check [*] shows that nothing has leaked out of the home
directory (even though at least on my Debian 10 system PolKit still
asks for authorization during the meson build).
Not perfect, but lowers a barrier to run the development version a lot,
as that does not anymore to trash your system.

Use the rate match io are to read the exact amount of samples we
need for this cycle from the ringbuffer. We can then request lower
latency.
There will also be less buffering in the audioconverter, which makes
our timestamps more accurate.
Instead of requiring the upstream node to resubmit the delayed
samples, keep the samples ourselves. The benefit is probably too
small to measure but it simplifies things a lot.
Use parse_string for everything else to use it as a string value.
Make it possible to use short name for the param.
so now you can do:
pw-cli set-param 55 Props '{ channelVolumes: [ 0.3, 0.3 ], channelMap: [ FR,FL ] }'
Implement routes on the device. This makes it possible for the
session manager to restore the device volumes.
Use validate_config to get the negotiated channels for the route
volumes.
UCM profiles can use the same ports, but with different priorities. One
good example is a phone, having an earpiece and a speaker:
- the default profile will put a higher priority on the speaker
- the "voice call" profile will put a higher priority on the earpiece
When switching to the "voice call" profile, we want pipewire to take
into account the priority change, so that the earpiece gets the highest
priority and is selected by default.
As the ports have the same name in both profiles, we have a single
instance of each port in memory, and therefore need to trigger a port
update when the profile is changed, so that the priority set by the new
profile is used.
Moreover, the UCM code updates only the priority inside the
`pa_device_port` structure, so this commit also makes sure we reflect
this value into the `acp_port` structure when enabling a device.
SCO socket connect may fail with ECONNABORTED if it is done too soon
after previous close. To avoid this in cases where nodes are toggled
between stopped/started rapidly, postpone release until the transport
has remained unused for a time. Since this behavior appears common to
multiple SCO backends, do it for all SCO backends.
Move SCO polling to a single place, and abstract mtu handling.
Autodetect suitable tx packet size based on rx, instead of relying on
the kernel providing correct values.
Parse the module arguments according to the pulseaudio syntax,
not our own syntax (which requires "" around a , delimter). Fixes
audio.position=FL,FR argument.

Since the data thread accesses the spa_bt_transport, its destroy event
needs to sync with data thread to avoid races.
Also check transport is present in places that need it.
