The Pro Link 1 replies with Audio-latency=0, patch that up to
1500ms to make it work again.
Previously it configured 1500ms as the default latency but that seems
unnecessary in the usual case.
Fixes#3698
We always need to add the Props param because it contains the
debug.aec.wav-path key, which is always available, even when the AEC
implementation has no properties.
Also add the debug.aec.wav-path PropInfo.
We can reuse the same code for setting input and output stream
properties. This also makes it possible to set the debug.aec.wav-path
on all streams, like the properties say.
For params that don't emit change events, the param enumeration does not
start core sync, and its enumeration may be incomplete if a previous
core sync completes first.
Fix by always starting a core sync if we are updating params.
This fixes dev_info.active_port being sporadically SPA_ID_INVALID if
there is event pressure, which causes do_set_volume randomly set the
volume on the node instead of setting it on the device. This can be
triggered e.g. by shaking the volume slider in Pavucontrol with mouse.
Convert capture and playback streams to any global channel position that
has been set. This can then be used to implement an upmix sink and add
such an example config.
Keep the target and source fd in sync when we get the new fd from the
server in remote-node.
This makes it possible to refactor some things and only schedule nodes
by triggering the target.
Also include and update the state of the device/stream in
collect_device_info so that we can compare it against the previous value
and emit a change event.
Fixes#3660
Add (minimal) reference documentation for each pipewire-pulse module.
Add some preprocessing to substitute @pulse_module_options@ in docs from
PW_KEY_MODULE_USAGE so the module options don't need to be repeated.
Produce Doxygen docs + generate manpages pipewire-pulse-modules.7,
pipewire-pulse-module-*.7
First check if all of the new buffers are ok before attemping to replace
our exising ones with the new ones. Else we might end up copying some
of the new buffers and cleaning them up twice later.
struct mix contain pointers to themselves (see do_port_use_buffers) and
cannot be copied by value, so they should not be stored in pw_array.
Store them in pw_map instead.
Trying rt scheduling policy while RLIMIT_RTTIME is set could result in
SIGXCPU if the limit is exceeded. Set an infinite limit temporarily
while checking if rt policy is allowed.
Emit error if message construction is not holding appropriate locks or
runs from wrong thread, so that the flush may be running concurrently.
This generally causes corrputed messages to be sent silently, and can be
fairly hard to debug otherwise in client applications.
Modern heterogenous multiprocessor systems rely increasingly on
scheduler hinting for efficiency gains and system optimisation.
This is especially true on embedded systems, where background
tasks such as audio daemons should be consigned to the most
power-efficient core in the system. Left to its own devices, the
Linux Completely Fair Scheduler tends to migrate Pipewire to
more performant cores, even when this is unnecessary.
Luckily, CFS can be told by a task to clamp its utilisation values.
Coupled with energy-aware scheduling, this allows the scheduler to
make better informed decisions about where tasks should be placed,
and what pstate to set for the CPU it is running on.
Enable the user to configure UCLAMP_MIN and UCLAMP_MAX values via
arguments to libpipewire-module-rt.

Allow PIPEWIRE_REMOTE / PW_KEY_REMOTE_NAME to contain a JSON array of
sockets to try to connect to, in order, instead of just one name.
JSON is restricted to utf-8 encoding. Also, this forces using JSON
syntax for paths that start with '['. This probably will not usually
cause much problem.
