SPA does not respect the C strict aliasing rules at all, so any code
that uses it must be built with -fno-strict-aliasing. Furthermore,
there is code in SPA that compares pointers that point to different
objects, so -fno-strict-overflow is also needed.
It uses the onnxruntime library to parse the onnx file and construct a
neural network. It uses the label field to setup the plugin and how to
map the various tensors of the model to input, output, control and
notify ports.
Add an example config for how to use the silero VAD ONNX model with the
noise gate.
With .enabled(), Meson doesn't have some magic that packagers rely on
to explicitly disable finding a dependency if an option is off. Drop
the unnecessary .enabled() accordingly.
The EBU R128 filter measures the signal and generates LUFS control
notifications for further processing.
It also adds a plugin that can convert LUFS to a gain (based on a target
LUFS).
Also add an example filter-chain to enable the EBU R128 measurement and
how to use the results to adjust the volume dynamically.

When spa-plugins is enabled, the gio-2.0 global dependency is
overwritten.
When bluez support is enabled, OR when gsettings is enabled, the gio-2.0
dependency is then detected as found. This means that
pipewire-module-protocol-pulse can end up enabling gsettings support
even if it has been forcibly turned off.
Rename the meson variables to ensure they are looked up separately.
The file is moved into a new "include-private" directory. This is done
because otherwise adjustments would have to be made to the list of installed
headers, the way include tests currently work and which files are
used for generating documentation.
HFP 1.9 adds LC3 as a possible codec in addition to CVSD & mSBC.
E.g. Pixel Buds Pro latest firmware supports it.
Add the RFCOMM side and codec selection for it.
vulkan_headers was a workaround for distributions providing pkg-config information
without the headers. Replacing it with a more conventional have_vulkan
and assert header availability if the option vulkan is enabled.
Enable LE Audio support by default if liblc3 is present, the Pipewire
implementation should be OK. Remove unused HAVE_BLUETOOTH_BAP define,
we don't have any #ifdefs for this.
The feature is still disabled by default in BlueZ, which also now takes
care of necessary hardware feature checks, and should be safe to enable
on Pipewire side.
Make BAP nodes align the first sample of their packets at multiples of
the ISO interval, counted in the shared graph sample position. This
skips a few samples (< 10ms) at the start of playback to ensure the
alignment.
Since the sinks align their flush timing to the graph time, this also
results to them sending packets corresponding to the same graph time at
the same real time instants.
Due to packet queues in kernel/controller, the playback may still be off
by multiples of packets. Kernel changes are needed to address that part.
This works towards making BAP left and right channels to be
synchronized in TWS headsets, where the two earpieces currently appear
as different devices.
* Add support for running the sink as a driver
* Detect which compressed formats are actually supported
* Correctly open/close/start/stop device according to the node commands
* Shift away from tinycompress and use Compress-Offload ioctls directly
to be able to access various caps information (including fragment sizes)
which are unavailable in the tinycompress API
* Implement SPA_PARAM_PropInfo and SPA_PARAM_Props support
Many distributions provide outdated libcamera versions. This change should also help making changes to libcamera itself.
System libcamera is kept a default to avoid breaking existing build processes relying to packaged libcamera.
* Decouple FFmpeg integration in pw-cat from the ffmpeg option; if
one wants to use Compress-Offload but not the ffmpeg SPA plugin,
it is then possible to just pass -Dpw-cat-ffmpeg=enabled to meson.
Likewise, this also makes it possible to build the ffmpeg plugin
without extending pw-cat.
* tinycompress does not need to be detected in the root meson.build,
since it is only needed by the alsa plugin.
Support Opus as A2DP vendor codec.
The specification for vendor A2DP codec is our Pipewire-specific one, so
it is compatible only with devices running Pipewire.
The file name "lc3.h" in the ETSI LC3plus package may conflict with the
actual LC3 codec, so try to find a file "lc3plus.h" instead. Also try
to find a pkg-config dependency for it first (in which case use lc3.h,
assuming it's in different directory). This can be fine tuned, if
something starts to package that library.
Since meson 0.59.0, a feature object has an `allowed()`
method which returns true when the feature is set to
'enabled' or 'auto'.
Utilize that instead of the previously used
not feature.disabled()
