As reported in #3217, PTP driver has to have the highest priority for packets to arrive in time
Everything connected to AES67 should be clocked by the Grandmaster clock
Whe using pw_*_new_simple(), pass the properties to the automatically
created context as well so that we can configure it.
This makes it possible to, for example, load the client-rf.conf using the
simple API as well.
If a client tries to update an ignored key, don't log a warning. Only
log a warning when one of the security properties changed.
This is what we used to do before commit
0dfa05117b
It fixes a warning when a stream disconnects and reconnects because
the serial.id changed.
This function is very much orthogonal in function to the usual
features provided by pipewire, and there does not seem to be any
3rd party users based on Debian Code Search and GitHub.
So let's remove it before any 3rd party users start depending on
pipewire for their valgrind detection.
Commit b5c21c1fbc ("pipewire: use dlclose unless PIPEWIRE_DLCLOSE is set to false")
introduced the PIPEWIRE_DLCLOSE environmental variable to
force/prevent the dlclose()ing of shared objects. However,
native pipewire modules were not adjusted to respect its value,
and instead have been still using `pw_in_valgrind()` to
determine whether or not they should be unloaded.
Fix that by adding a private `pw_should_dlclose()` function
and using that in impl-module.c:pw_impl_module_destroy().
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.
This reverts commit 7465175ad0.
wait_started() is called before the stream is connecting and so
exits with an error immediately, which then makes the stream start
too early and block.
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.
When the session manager sends an error to the client, it typically
also destroys the node after the error, which causes the stream to go
to STATE_UNCONNECTED via proxy_removed(). In that case, make sure
we exit the loop early, otherwise it will take 30 seconds to unblock
gst_element_set_state()
First, make the error permanent by calling pw_stream_set_error()
and when this emits an error state again, report that to GStreamer.
Do the same in pipewiresink, which didn't even have the
pw_stream_set_error() call before, so the stream wasn't really going
into an error state at all.
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.
Remove group permission on the system manager socket so that restricted
clients cannot use it to get unrestricted access. It is assumed that the
session manager system service (wireplumber) is running as pipewire user
and will get access to the manager socket, while other clients are
members of the pipewire group and will only get access to the normal
socket.
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.

If the link isn't destroyed, don't allow changing state to
PAUSED for states < PAUSED. For example, if the deactivation
is called during the link being in NEGOTIATING it could then
jump directly to PAUSED and believe it is prepared.

This changes the value declared (3 currently versus 0 following this
patch). I have not seen code checking this version number.

Support an array for the node.group and node.link-group properties.
This makes it possible to make a node member of multiple groups and
link-groups.
