First clear the started flag so that we ignore scheduling from the
follower. Then stop the follower and the converter.
This is the sequence we follow when deactivating a node, so do the
same here.
it is important that the node is not scheduled anymore when we clear
the format in suspend or else we might crash.
See #2877
When in passthrough mode and there is no converter, simply return
our own PortConfig parameter with our direction and passthrough mode.
Otherwise, use the PortConfig from the converter but filter out only the
PortConfig that matches our direction.
This fixes enumeration of PortConfig on the adapter.
Make a new variable to iterate the other ports so that we can use the
original port to emit notifications.
Fixes Latency and other params set on DSP ports.
When we are simply enumerating the params, just collect the info
but don't act on them, like clearing the format or recalculating
the latency.
This avoids some useless work when enumerating params.
Use the more complete configure_format function to clear the format
and buffers when the EnumFormat param changed.
When the follower updates EnumFormat, it probably wants to renegotiate
to a new format, so clear the current format so that we do that when
starting the next time.
EnumFormat should also not only return the current format in case we
are negotiated but it should return all possible formats.
See #2832
After the ports are reconfigured, we need to perform the setup again so
that buffers and processing can happen with the right settings.
This fixes an issue when autoswitching between A2DP and HFP with
bluetooth headsets when there is also a stereo capture device available.
The input stream of the browser is quickly reconfigured between stereo
and mono with only a Pause command in between, clearing the setup state
is enough to redo the setup when going back to Playing.
Fixes#2764
This reverts commit 6c963ed933.
This code was meant to set a filter on the format for the follower
but is not implemented yet.
Problem is that the unit tests and wireplumber call this code and would
need to be patched.
Just like the optional build, make all field parsing optional. This
will leave the fields with their default values if they are not parsed
from the param.
We can then remove our custom functions and use the generic ones in
various places.
Set up the adapter and then set the started field to true before we
Start the follower and converter. It is possible that the follower will
start processing immediately so the started state needs to be set
correctly.
Similarly, first perform the Pause and Suspend calls on the follower
and converter before clearing our buffers and format so that things
are stopped properly.
See #2764
The parsing functions expect float values in the default locale so use
the spa_dtoa function to generate such a float.
Fixes setting params with floating point values when the locale is not
the default locale.
When we were using the resampler and then bypass it when the configured
rate == 1.0, we create a pop because we don't process the queued data in
the resampler anymore.
Avoid this by keeping the resampler active as soon as the rate property
is set on the audioconvert. The resampler itself will use a more
efficient copy method in that case anyway and it is expected that the
rate will change again later when we need to reactivate the resampler.
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 ..
So that we can reuse optimized versions in unoptimized noise
functions.
Do allocation a little different so that we can align everything
from the start.
Loop though coefficients, when all are 0, clear the destination.
When only one coefficient is used, simply copy with volume.
Otherwise run the complete convolution.
Don't count the sum for unused matrix coefficients. When doing pairing,
we set the mask to ~0 and so we would otherwise count too much.
Apply normalization to the active matrix coefficients, not whatever the
loop variables end up being at the end of the loops.
