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
Add a new latency param that contains a latency object.
The latency object contains the min and max delay from a port to
the terminal sink/source. It is also possible to express this
delay as a fraction of the quantum to avoid having to recalculate
the latency every time the quantum changes.
This requires a helper script: doxygen doesn't differ between static methods
and static inline methods. EXTRACT_STATIC defines whether it parses *any*
static method but we're currently using all C files as input files as well. We
cannot convince doxygen to just parse static inline functions in header files
so for SPA we hack around this: meson passes the spa headers to a shell script
with simply copies those changed to `/* static */ inline void (foo)` and doxygen
then runs on those header files.
The result: we get all spa functions added to your doxygen output at the cost
of a few sed calls.
Subdirectories buffer, control, debug, monitor, pod, support and utils, others
are still missing. Headers are grouped either per subdirectory (e.g. buffer/
gets added to group spa_buffer) or per-file (e.g. spa_json is a separate
group), whatever seemed like the most sensible approach.
This flag is used to announce that the respective key is mandatory and
therefore the object containing this key is not suitable to be merged
with other objects missing it.
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.
Easier to use than strcmp() since their return value matches expectations. And
they do what is expected with NULL strings, two NULL pointers are equal, one
NULL pointer is not equal.
Most of the time when we convert a string to an integer we only care about
success. Let's wrap this with a helper function that sets the value to the
result and returns true on success.
Some properties can be part of a params field in the Props object
and contain the string key and the pod value to be configured. This
is easier to use than using the regular id.
Add the fact that the property is also part of params in the PropInfo.
SPA_MEMBER is misleading, all we're doing here is pointer+offset and a
type-casting the result. Rename to SPA_PTROFF which is more expressive (and
has the same number of characters so we don't need to re-indent).
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.
Move the icon we get from bluez to a separate property, it is not
a good icon to show.
Copy form factor from device to node properties.
Set device.bus in the device properties and copy it to the node
properties.
Use form factor and bus to make a nice icon-name for the node and
device.
Fixes#1064
All files in spa/include are being installed anyway, so to avoid having to
list each file one-by-one let's use meson's install_subdir() to install all
of them in one go.
Previously, the return value of `strrchr()` was not checked
in `spa_log_impl_logv()` which could cause a segmentation fault
in `snprintf()` if the `file` string argument does not contain
any directory separators ('/').
For example,
./build/spa/tools/spa-inspect ./build/spa/plugins/alsa/libspa-alsa.so
could run into this problem:
Program received signal SIGSEGV, Segmentation fault.

as in that particular case, the filename was returned by libasound,
and it was just "parser.c".
Furthermore, separate the static variable from the rest, and apply
the `const` qualifier to the pointers in the `levels` array.
We can't move past the } or ] or we might miss the end of the
container. Now that we ignore \0 it is not a problem if the \0
is placed at the container boundary.
node.latency also influences the pipeline latency in that it can
push the latency above the default value.
node.max-latency, instead, is only used to clamp the final latency
of the pipeline.
