config.h needs to be consistently included before any standard headers
if we ever want to set feature test macros (like _GNU_SOURCE or whatever)
inside. It can lead to hard-to-debug issues without that.
It can also be problematic just for our own HAVE_* that it may define
if it's not consistently made available before our own headers. Just
always include it first, before everything.
We already did this in many files, just not consistently.
Make a function that can initialize raw audio info from a dict and fill
in the defaults. We can use this in many of the modules when the audio
format is parsed.
Use the helper instead of duplicating the same code.
Also add some helpers to parse a json array of uint32_t
Move some functions to convert between type name and id.
Add spa_json_begin_array/object to replace
spa_json_init+spa_json_begin_array/object
This function is better because it does not waste a useless spa_json
structure as an iterator. The relaxed versions also error out when the
container is mismatched because parsing a mismatched container is not
going to give any results anyway.
So that all nodes attach to some driver to be scheduled.
For the virtual sink/sources this is a normal thing and we can remove
the custom settings.
For normal stream, this now makes it possible to link pw-play directly
to pw-record and have it transport data.
Fixes#1761
For the modules that require a driver, don't add ourselves to
the pipewire.dummy group but instead just use the NODE_WANT_DRIVER
property to be assigned to a driver.
This makes it possible for the nodes to move to another driver than the
dummy driver (which has very high priority) and it avoids resampling in
cases where the nodes are linked to an audio source or sink.
