libcamera commit 1c4d4801850559d6f919eef5c2ffbaf7675dbc46
changed the return type of libcamera::ControlList::get()
to be std::optional<T>. Adapt the code to this change.
Fixes#2575

R->A calculation removed: it wasn't valid anyway. No behavior change.
Placed existing A in there directly.
cosh window -> strangely tweaked exp window: remove the discontinuity
at the border, which is wrong for a window function. If A changes in the
future, this window will be better. With the current A, you will not be
able to tell the difference on any graph. (Of course, it's not a cosh
window anymore.)
Fixes#2574
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 device is not know at SelectConfiguration time, so the settings
argument in select_config is currently unused. Pass on a global settings
dict instead, so that codec parameters can be configured.
Also add settings argument to caps_preference_cmp.
Bump codec API version.
Add a flag A2DP_CODEC_FLAG_SINK to incidate a sink endpoint.
Also enum_config and caps_preference_cmp may need to know whether the
codec is being configured for SRC or SNK. Also add the flags argument to
init_props.
Bump codec API version.
a2dp-sink writing duplex data to the BT socket breaks a2dp-source source
polling, also in A2DP source role. Hence, use the timer-based polling
workaround always in duplex mode.
As currently implemented, input format convert channel remap is no-op.
This is because although the out_datas array is permuted, the original
pointer array is not referred to later on, so the only effect is that
the temporary data array is stored in permuted order.
Fix the permutation by permuting the pointers only for the conversion
step.
Make a new noise method called PATTERN and use it to add a slow (every
1024 samples) repeating pattern of -1, 0.
Only use this method when we don't already use triangular dither.
See #2540
When the stream has more channels than the filter inputs or outputs,
don't try to connect an invalid filter port but ignore the input and
clear the output.
pthread_getschedparam() always returns non-negative values, so checking
if its return value is less than zero always evaluates to false.
Also, pthread functions don't set errno. While logging a warning
message, use the return value of pthread_getschedparam() instead of
errno.
