Add a new seq field in the param-info struct. Users can use this
field to keep track of pending param updates.
Store the latest seq number of the param update in the seq field. Remove
all params that don't match the sequence number because they are too
old. This avoids duplicate old params in pw-dump output.
Rework the pulseaudio manager with this same method.
Make it possible for a aec-plugin to provide props/params
through module-echo-cancel and make it possible for a
aec-plugin to listen and react to these props/params getting updated.
Add method enum_props() that is used under setup_streams() to
get props from aec_plugin.
Add get_params() and set_params() for updating and getting
aec-plugin params under the input/output_param_changed calls
and getting params under setup_streams().
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 ..
This fixes several integer overflow problems in the POD parser, as well
as fixing a returns-twice warning from GCC and integer truncation
problems in SPA_FLAG_CLEAR and SPA_ROUND_DOWN_N. The integer overflows
can result in a tiny POD being treated as a huge one, causing
out-of-bounds reads.
spa_pod_parser_can_collect and spa_pod_parser_getv were inconsistent
with each other. When parsing crafted POD, this could cause a type
confusion or stack overflow.
When we are already past the size of the buffer, don't bother calling
the overflow callback anymore, the buffer is already corrupted.
Otherwise it would be possible to have the overflow callback fail the
first time around, some data will be skipped, and then the next
overflow callback would succeed, giving the impression that all is
fine.
Add a unit test for this.
For backward compatibility with old Wireplumber releases, support the
old api.bluez5.a2dp.sink/source names, and use them in object events
instead of the media.sink/source names.
Add methods activate() that is called before first call to run() when
stream starts and deactivate() that is called after last call to run()
when stream stops. This makes it possible for aec-plugins to reset their
state between streams.
Although pos will be set to 0 in the first iteration, the compiler does
not seem to figure this out, so help it a little:
../spa/include/spa/support/log.h:306:21: warning: ‘pos’ may be used uninitialized [-Wmaybe-uninitialized]
306 | pos += sprintf(str + pos, "%02x ", buf[i]); \
| ^~
../spa/include/spa/support/log.h:301:13: note: ‘pos’ was declared here
301 | int pos; \
| ^~~
A lot of code calls spa_hook_remove() from error paths where the hook
and therefore the list may not have been initialized.
This leads to null-derefences.
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.
Add an EMPTY chunk flag to mark a piece of memory as 'empty'. For audio
this means silence.
Use the empty flag to avoid mixing 0 samples.
Set the empty flag in output buffers on audioconvert.
When uclibc is build with !UCLIBC_HAS_LOCALE the macro
__LOCALE_C_ONLY will be set, use this to disable unsupported and
not required(due to only supporting the C locale) locale functions.

We need exactly 4 hex characters, everything else is refused. We
also copy those characters directly to the output string without
assuming any encoding.
See #2337
Make helper method to parse thread properties and add 2 new properties
to control name and stack-size of the thread.
Use properties when creating threads with the default utils.
Use the default thread utils instead of pthread_create so that the
properties are used.
Not all string functions have a POSIX compliant locale aware version
(eg. strtof_l). Instead uselocale [1] should be used, which allows
switching the locale of a thread to a welldefined one and restoring it
afterwards.

And use this in spa_json_format_float() where we also avoid invalid
json floats.
Use json float format in some places where we serialize json floats.
Add a unit test.
See #2223
