api.acp.hidden-ports and api.acp.hidden-profiles can be used to pass
a json array of ports and profiles to hide. They will not show and
will not be selectable.
Make a real debug context with a log function and move it to a new file.
This way we don't need to redefine a macro.
Make a new context for debugging to a log file. Make new functions to
debug to a log file.
Move the stringbuffer to string utils.
Integrate file/line/func and topics into the debug log.
We can remove some more things from the pipewire log_object function and
also add support for topics.
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.
uint32_t i;
for (i = 0; i < SPA_N_ELEMENTS(some_array); i++)
.. stuff with some_array[i].foo ...
becomes:
SPA_FOR_EACH_ELEMENT_VAR(some_array, p)
.. stuff with p->foo ..
Just like the latency, move the codecs to the device Route param.
This way, it is easier for the session manager to save and restore
the codecs as part of the Route settings.
This property is exposed on the device Route and forwarded to the
nodes. It then configured the process_latency.ns field, which
influences the reported port latency.
This makes it possible to change the internal port latency on the
sink and source with pavucontrol and tweak the synchronization to
compensate for internal latencies in the device.
Mark some structures, arrays static/const at various places.
In some cases this prevents unnecessary initialization
when a function is entered.
All in all, the text segments across all shared
libraries are reduced by about 2 KiB. However,
the total size increases by about 2 KiB as well.
Use _alibpref to check if a device needs a UCM local config. Mark
the device as such and use this to set the OPEN_UCM property on
the device.
Open the UCM for a card when the device has the property set. Use the
same logic for loading the UCM as the acp code.
See #1251
When we add a new listener to an object, it will emit the full state
of the object. For this it temporarily sets the change_mask to all
changes. Restore the previous state after this or else we might not
emit the right change_mask for the next listener.
Consider the case where one there are two listeners on an object.
The object emits a change and the first listener wants to enumerate the
changed params. For this is adds a new listener and then triggers the
enumeration. If we set the change_mask to 0 after adding the listener,
the second listener would get a 0 change_mask and fail to update
its state.
This replaces the manual check for "true" and some (inconsistent) return value
of atoi. All those instances now require either "true" or "1" to parse as
true, any other value (including NULL) is boolean false.
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.
So that we can know if this node has routes or not.
Nodes without routes might need their volumes restored directly
with the node properties, like streams. Nodes with a route need their
volumes set on the device managing the node.
Remove the soft mute/volume events, add a new method to get the soft
volume and use the volume_changed event to emit the changed soft and
monitor (real) volumes event for the node.
Make sure the monitor ports always uses the monitor volume, which is the
real volume unaffected by the mixer volumes.
This configures the soft and real volume on the sink/source in all
cases and makes the monitor port follow the real volume of the sink.
See #897
Add save property to Profile and Route params to notify the session
manager that they should be saved. Let the session manager only save
the Profile and Routes with the save flag.
Make pulse-server set the save flag on Profile and Route changes.
The result is that we can make a difference between user requested
changes and automatical changes and only remember the user preferences.
When a port changes availability, first check if we need to perform
a profile switch, if not select the new best port.
Only poll events and set_param can cause a param changed events.
Keep track of all the changes in the param user data and at the
end of the poll/set_param emit one notification for all changed
params.
When the acp-device impl struct is passed to the log func, it is
possible that when this device is removed, another device using acp
is going to crash while logging a message
When we have accurate enough hardware volume, set the software volume to
1.0. Also fixes the issue of going to 0 volume and then staying silent
until we raise the volume above 1.0.
