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.
Handle 1 channel as a mono channel, which gets copied to all outputs
or gets the average of all inputs.
Fixes the case where a mono channel is handled like a FRONT channel
and then gets attenuated when mixed into left and right.
When we don't have any input buffers, recalculate the rate match
size field so that we can know the size of the expected buffer.
We already do this when starting but it might have been done with
a different quantum.
When adding a listener, don't add a listener for the resampler because
it does not contribute to the result, we only listen for results from
the resampler.
Some follower nodes don't support all audioadapter params (For example, param
SPA_PARAM_Props is not supported by 'support.null-sink'). This change adds a
check to avoid unsuported errors when requesting a param that is not supported
by the follower.
Scale the buffer size with the rate conversion ratio. Also make sure
that we can at least produce a maximum quantum of samples.
If we have large upconversion (8KH -> 48KHz) and small input
buffers, we would not allocate enough space for the output buffer
and cause xruns in the sink.
Fixes#1809
Don't use the previously skipped sample to calculate the remaining
amount of samples or else we remove one sample too much in some cases
and cause distortion, mostly when downsampling.
Fixes#1646
For SPA libraries that we link against elsewhere in the tree, declare a
declare a dependency "foo_dep" for that library that specifies how to
link to it. Then use that dependency in the various targets.
This removes the knowledge of how to link with the library from the
target which can treat it as just another dependency.
In the case of optional libraries (e.g. the journal support lib) we can
then use declare_dependency() to declare an empty dependencies and thus
link them unconditionally in the target.
