Piggy back on the Latency param change to emit a stream changed event
because we now might have a link between the stream and a device.
We should really watch for new links and emit change events for the
streams that it links to.
Fixes#3522
Let the source write into a ringbuffer when there is data available.
We then read from the ringbuffer when scheduled and use a dll to keep
the delay constant. We can later make this a driver and use the rate
correction to tweak the timeouts instead of resampling.
See #3478
Round down the size and avail to the frame size to make sure we always
send aligned frames.
When we don't have the required size, set the buffer to 0 but still send
whatever we have in the ringbuffer or else it stays there until some
unknown time when it gets flushed out again with new data.
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
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
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.
Makes
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.
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.
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.
