Add new spa_debugc_ funnctions that take a context. The user should also
redefine the spa_debugc macro to handle the context.
Use this to let some plugins log the pod and format to the log without
using the global logger.
Also use this to remove our custom pod logger function by reusing the
spa one with a custom context.
BlueZ may send multiple PACs in the capabilities delimited by zero LTV.
Handle this case by selecting the "best" one.
The configuration size may also for BAP generally be different from PAC
size.
When reading the timerfd gives an error, we should return right away
because the timeout did not happen.
If we change the timerfd timeout before reading it, we can get -EAGAIN.
Don't log an error in that case but wait for the new timeout.
The free buffer check must happen before writing to check for leftover data in buffers. In case data is left over from previous submission, bitpool mustn't be increased.
Also improved logging by adding bitpool to the log message.
AVDTP in principle allows 62 endpoints, but in practice it appears some
devices (Samsung Galaxy Buds2 Pro, Redmi Buds 3 Lite, probably others)
fail to connect A2DP when the number is somewhere above 24. A2DP
connection works when initiated from the Central, but not when the
device itself does it, so these devices are not fully broken. We should
reduce the number of registered A2DP endpoints to avoid running into
problems with such broken devices.
Some of our source codecs are the same actual codec with the same
configuration, and don't need separate source endpoints.
Allow codecs to not have a registered endpoint (fill_caps == NULL), and
tolerate codecs with the same endpoint name. In codec switch, keep
track separately which of the codecs with the same endpoint name the
local endpoint is currently associated with.
The graph cycle goes: driver timeout -> process output nodes -> process
driver node. Hence, driver should produce buffers in the timeout,
otherwise there's one quantum extra latency.
Make the bluez5 media/sco sources as drivers put a buffer to io before
indicating ready, and as follower do it in process. Also make checks if
io == NULL, and don't set io->status to HAVE_DATA unless there really is
a buffer ready.
Introduce `unregister_media_endpoint()` to unregister the specified
media endpoint object from dbus. Moreover, move the logic that decides
whether or not a particular codec should be registered for a given
direction into `endpoint_should_be_registered()` and use that in
both `(un)register_media_endpoint()`.
Driver timeouts need to be started/stopped when we switch from follower
to driver or vice versa.
The BT sources fail to do this, so fix it. Sinks already do it right.
Use separate timers for driving graph and for flushing, since they don't
have the same period.
Flushing is done based on the time positions of the next sample to be
written, so it will stay in sync with the graph. Because writing too
much data to SCO sockets generally only causes the device to skip ahead,
we don't need to handle the case where the writing has been lagging.
This fixes simultaneous playback to both ALSA and SCO sinks from the
same graph, with SCO as driver, which previously produces broken sound
(e.g. with pw-play --latency 512, linked to the two sinks) ALSA nodes
require regular driver intervals, which was not true previously.
Bigger buffer allows for more fluctuation in transmission rate without
sound glitches.
It doesn't matter much for latency, as under normal conditions we are
not producing data faster than the BT adapter can transmit, so the
buffer generally is almost always empty or full, and in the latter case
we have to reduce the bitrate.
Clang 15 at least with my build configuration emits warnings about
function prototypes that lack argument types. Most notably this
happens with functions that take no arguments which in compiler view
equates to the void type i.e. void f(void) instead of void f(). As I
understand, this will become an error in some future Clang release,
so might as well fix it now.
Since these were discovered not by a linter but by the actual compiler
for my particular build configuration, some f() may have escaped for
now. But at least it's enough to build PipeWire with most optional
features enabled even when -Werror=strict-prototypes is enabled.
For anyone else wanting to have a go at this, these can be upgraded
from warnings to errors by adding -Werror=strict-prototypes to the
custom CFLAGS which probably works with GCC, too, but has only been
done with Clang 15.0.2.
Finally my editor automatically stripped trailing spaces upon saving
the modified files. I assume it's probably not worth keeping those
invisible bytes around but this may have slightly dubious implications
as it did also turn indented empty lines of JACK license header into
regular empty lines.

The codec may need to take into account endpoint preferred QoS values,
so parse this information and pass it to the codec's get_qos.
All the QoS struct values need to be set, as otherwise BlueZ may pass
uninitialized zero values over the air, which devices can reject. This
does not apply to CIG/CIS ids, which are automatically allocated by
default.
Fixes connecting to nrf5340 devkit, which requires a valid TargetLatency
value.
Commit 947ee152d3 ("bluez: check dbus service before enumerating objects")
introduced a check that would esure that GetManagedObjects()
is not called if the "org.bluez" name has no owner. This
was done to avoid auto-starting the bluez daemon.
However, this is not needed because it is possible to set on
a per-message basis whether or not the destination service
should be automatically started by the dbus daemon.
By default no modem is allowed.
Property "bluez5.hfphsp-backend-native-modem" can be 'none', 'any' or the
modem device string has found in 'Device' property of
org.freedesktop.ModemManager1.Modem interface, e.g. for PinePhone
"/sys/devices/platform/soc/1c1b000.usb/usb2/2-1".
This allows the HFP HF to retrieve the list of calls with their index,
state and remote number (if available).
This commit shared the list of calls between modemmanager.c and
backend-native.c, and switches call state storage from ModemManager
states to CLCC states
