We alwats want to adapt to the rate of the graph and not the
samplerate that was configured with the PortConfig.
This fixes samplerate switching again.
Add an option to do a hilbert transform on the generated rear channels
to do a 90 degree pahse shift on them. This can improve spacialization
of the rear channels.
See #861
For merger setup (consuming a source) we want to expose the channelmap
of the remixed signal (to the application/sink).
For splitter setup (providing data) we want to expose the channelmap
of the original source (before remixing to sink).
Hide the merge channel props because they contain the channelmap before
mising and we want to expose the remixed signal in merger mode.
This fixes some weird volume issues when an input stream is linked
to a source and is remixing, like when a stereo stream is captured
from a mono source.
Keep track of the format as given in the PortConfig.
Instead of blindly fixating the negotiated format to whatever default,
use the PortConfig format to fixate to something better.
This makes the channels/position, rate or format match the PortConfig
format when this is possible and results in the least amount of conversions.
It mostly improves the handling of wildcard formats, were a stream only
specifies some fields and leaves the other free.
A concrete case is WINE that uses the pulseaudio FIX flags to omit the
number of channels and rate. With this change, the stream will negotiate
to the format of the linked sink and obtain the channelmap from it.

pipewire will allocate buffers aligned to the max alignment required for
the CPU. Take this into account and don't expect larger alignment.
Fixes a warning in mixer-dsp when the CPU max alignment is 16 but the
plugin requires 32 bytes alignment for the AVX2 path (that would never
be chosen on the CPU).
See #2074
Currently, the code allocates
sizeof(header) * sizeof(item) * n_items
bytes instead of the more appropriate
sizeof(header) + sizeof(item) * n_items
Fix that by simply changing the first multiplication to addition, and
furthermore, use a flexible array member instead of a zero-sized array.
Found by clang-tidy.
Since 01c6fd0a88 the
minimum required meson version is 0.59.0, and since
meson 0.58.0, `get_variable()` on a dependency object
accepts a positional argument. The "type" of variable
(internal, pkgconfig, etc.) in that case does not need
to be specified explicitly.
Parse the quantum_limit parameters and use this to scale the buffers so
that they can contain the maximum allowed samples instead of the
hardcoded 8192 value.
See #1931
Ignore latency params on the monitor ports of merger. They interfere
with the latency reporting set by the adapter.
The adapter will set the latency param from the follower on port 0 in
the converter, so pass this on to the merger as the latency and ignore
all other updates.
Fixes a case where the latency of a sink would become 0 when a monitor
port was recorded from.
When the follower has no param to enumerate we would keep on enumerating
the params of the converter forever. Fix this by setting the next value
to something that would then stop the iteration.
Also increase the amount of bits for the follower because it might need
them.
Make the alignment parameter optional when negotiating buffers.
Default to a 16 bytes alignment and adjust for the max cpu
alignment.
Remove the useless align buffer parameter in plugins, we always
set it to 16 anyway.
Use `meson.project_{build,source}_root()` instead of
`meson.{build,source}_root()` because those functions
do not work as expected when used inside a subproject,
and they have been deprecated in meson 0.56.0.
