Change codec factory names to api.codec.bluez5.*, so that they won't
conflict with old config file lib name rules for api.bluez5.*
Specify the fallback library name when loading the codecs, so that it
works without the rules in config files.
Each dictionary needs to fully match but out of the dicts we have, only
one needs to match to apply. Reword that for clarity.
Also document regex vs normal string comparison vs the magic null
string.
Make easier to package A2DP codecs separately, by splitting each to a
separate SPA plugin. Adjust the code to not use a global variable for
the codec list.
The A2DP SPA interface API is in the bluez5 private headers, and not
exposed in installed SPA headers, as it's too close to the
implementation.
Instruct the policy to not configure audio adapter nodes in DSP mode. Instead,
Device nodes will always be configured in passthrough mode, and client nodes
will be configured in convert or passthrough mode depending on whether the
client format matches the device format or not.
For hdmi and iec958 devices, enumerate the iec958 formats and
codecs. Initially only PCM is supported as a codec but with
a property or an init option, the list of codecs can be dynamically
configured.
aptX-LL sink devices may send back mSBC encoded data corresponding to
microphone input. It appears to be enabled when the bidirectional link
is set in the caps, and the device also supports this.
Implement mSBC decoding in the duplex channel.
Tested to be working on Avantree Aria Pro.
Support the low-latency variant of the aptx codec.
The magic mostly seems to be on the device side, since the stream is the
same as standard aptx, but latency is smaller even if stream/packet
sizes are the same.
Sound output latency is noticeably less than with the standard aptx.
Tested on Sennheiser HD 250 / Avantree Aria Pro.
The codec in principle also supports bidirectional duplex streams,
but that is not implemented here.
Enable SBC-XQ by default, and move it at the end of the codecs list, so
that bluez does not connect to it automatically except when it is the
codec used previously.
When the codec is disabled by quirks, it won't appear in the codecs
list, and so can't be selected by user (and so won't be connected
automatically).
However, since SelectConfiguration does not carry information which
device is in question, we cannot prevent BlueZ connecting to the codec
even if it's disabled for a specific device. If the "impossible" occurs
regardless, we won't reject the connection and the profile will be shown
as the generic "A2DP" one. If the sound is garbled, the user can select
some other profile that works.
Add module that switches bluez device profile to HFP/HSP if an input
stream (non-monitor, autoconnect) appears, and the current default
output device is bluez one that does not have input route.
When all input streams are gone, switch all changed profiles back.
Pending restore state is saved to session manager state files, in order
to restore it if e.g. devices get disconnected. This usually is not
currently necessary since the bluez5 plugin prefers to connect to A2DP
over HFP, but might matter in future with backchannel-enabled A2DP
codecs.
200ms seems a little small, some plugins initialize themselves from the
RT thread and get killed. 2 seconds seem to be a better default.
The important part is that there is a limit so that runaway processes
are killed and don't lock up the system.

Install the config file in $PREFIX/share/pipewire so that a factory
reset can be done by wiping /etc and /home.
Add this new directory to the search path.
System wide config can still be done in /etc, user config in
$HOME/.config/pipewire/ by copying files from $PREFIX/share/pipewire
Fixes#1191
Make a new softVolume property that contains only the soft volume
to apply.
In the case of HW/SW volume, we pass the real volume in the
channelVolume and the leftover volume in softVolume. We don't
use the monitorVolume for this anymore because it is a completely
separate volume handled by the merger node.
This way, channelVolume always represents the effective volume
set on routes, channelmix and merger and only the softVolume (when
available) is applied as software volume by channelmix.
This makes things map a bit better to what is actually happening with
the real volume and leftover software volumes after applying the
hardware volumes in the device.
With this change, the volume on the monitor is not affected by the
sink volume anymore and we can use the monitorVolume for this later.
This also means that the monitor volume in pavucontrol of the sinks
does not change when the sink volume changes. PulseAudio is inconsistent
here: If the volume is HW, the monitor volume is not affected, if the
volume is SW, it is. In PipeWire there is an option in merger to
let the volume affect the monitor with monitor.channel-volumes = true.
The start-delay adds extra silence to the buffer before starting the
playback. The idea is to have more time to adapt to the device
startup and set the timer more accurately.
See #983, #431
Auto-connect all paired & trusted devices on startup.
Since devices that already connected or powering off would reject the connecting requests, it should be fine with this behavior.
Also reconnect remaining profiles if only partial profiles are connected.
Make arrays from config sections that should really be an array.
Having the module name as the object key technically makes it
impossible to load the same module twice because the key can only
be once in the object.
The same applies to the context.objects and context.exec sections.
This also makes it somewhat easier to parse the config..
