The WebRTC echo canceler can support different rates and channels for
the record, out and playback streams.
Add a new method to pass this config to the echo-canceler.
Older gcc versions seem to require the members to appear in the
designated initializer in the order they are in the definition of
the struct when compiling C++.
otherwise compilation fails with:
../spa/plugins/aec/aec-webrtc.cpp:167:1: sorry, unimplemented:
non-trivial designated initializers not supported
};
^
Place the methods on the interface so that we can call them.
Rename create to init because that is what it does.
Add support for listener and events so that we can signal property
changes later.
Move all backends to dynamic libaries loaded with spa_plugin_loader so
new backends not needs changes in pipewire or pipewire dependency to
external code
