The libcanberra calls use libtool, which can not be called from multiple
threads at the same time. Use a global lock to serialize these calls in
the x11-bell module.
This is only a problem when multiple libcanberra calls are made in the
same process, such when you load the x11-bell module twice. There is no
guarantee that other libcanberra calls will not interfere but for now
we only use libcanberra here.
Fixes#2834
The jack client API expects the ports to unregister when a jack client is
deactivated and to register when it is activated. We use pause/resume
for deactivate/activate and don't really destroy the ports.
Track the state of the node (client) and emit port registration when it
changes state. Also make sure we don't emit a port registration when the
node is deactivated.
Fixes#3260
Doing inotify on /dev is not a good idea because we will be woken up by
a lot of unrelated events.
There is a report of a performance regression on some IO benchmark
because of lock contention within the fsnotify subsystem due to this.
Instead, just watch for attribute changes on the /dev/videoX files
directly. We are only interested in attribute changes, udev should
notify us when the file is added or removed.
Only update the avail when we did a snd_pcm_forward(). Otherwise
we might think there is more available than there really is and we
might get xrun.
See #3395
For sink nodes, keep a separate device_info around for the sink and
the monitor source part of the node. Only emit changes for the sink
and monitor source part when it changed.
See #3388
This function sends a DBusMessage on a DBusConnection
and sets the reply callback of the resulting DBusPendingCall,
as well as properly cancelling the pending call if anything fails.
before gcc 10 its not supporting pointer dereferencing in __typeof__.
so made changes according to that. Fixes#3375
clang also defines __GNUC__ and resolves '4' along with __clang__ which
resolves '1'. On any version of clang, __GNUC__ and resolves '4'.
anyway clang has this feature since version 3.
Make sure don't handle names ending in .monitor as a valid sink (because
it's a monitor on the sink).
Make sure we don't return a sink (monitor) as a source accidentally but
only when explicitly requested by name with the .monitor extension.

pactl set-sink-volume alsa_output.pci-0000_00_1b.0.analog-stereo.monitor -5%
pactl set-source-volume alsa_output.pci-0000_00_1b.0.analog-stereo -5%
fail as expected.
We don't actually use this counter anywhere.
Change the counter to a mask that will contain object specific changes
to the params. This should make it possible to track what kind of
changes where done to the object and make it easier to emit the right
events later.
The wireplumber unit test sets metadata on object 15, which happens to
be a module.
Allow metadata on other objects for now. It would be nice to disallow
this in the future, though.
Tag the sink/source as HARDWARE when it's not virtual, the presence
of a DEVICE_API property is not a good check.
Make a method to check if a node is a NETWORK sink/source to make it
use the same logic everywhere.
It seems there are drivers that don't return a good values and we end up
with a lot of delay or automatic disable of htimestamp when the values
look too off.
Enable LE Audio support by default if liblc3 is present, the Pipewire
implementation should be OK. Remove unused HAVE_BLUETOOTH_BAP define,
we don't have any #ifdefs for this.
The feature is still disabled by default in BlueZ, which also now takes
care of necessary hardware feature checks, and should be safe to enable
on Pipewire side.
Add a thead-loop.start-signal option that will do a signal before
entering the thread loop. Doing the signal in all cases can confuse
apps that don't expect the signal.
Make module-rt use the thread-loop.start-signal.
Fixes#3374
Since the recent changes to the RT module in Pipewire 0.3.75, some
applications such as those using OpenAL-Soft crash on startup if
neither the session nor the system bus is available. For example:
bwrap --dev-bind / / \
--bind /dev/null /run/dbus/system_bus_socket \
--bind /dev/null $XDG_RUNTIME_DIR/bus \
openal-info
Will result in a crash with the following error message:
dbus[1626147]: arguments to dbus_message_new_method_call() were
incorrect, assertion "path != NULL" failed in file dbus-message.c
line 1373.
This is normally a bug in some application using the D-Bus library.
The RT module previously failed to load if no bus was available, but
after the recent changes, the init. logic runs in a thread, and failing
to obtain the bus no longer causes the module to fail to load.
Then, functions called later such as `pw_rtkit_make_realtime` assume
the bus is available and try to use it, causing the error above.
Put the logic for obtaining and checking the bus back to `module_init`,
so the module fails to load again if no bus is available.
