When we do invoke from the loop thread, first process the pending
invoke items before handling ours. This can be used to sync the
invoke queue before cleanup.
Keep the output port buffers in a special mix info. They should
stay there even when the mix is removed and should only be cleared
explicitly with a NULL Format or 0 use_buffers.
When we destroy a proxy, mark it as zombie until the server removes
the id. This way we can still keep the id locked with a valid entry
and remove it later.
Implement per channel volume on channelmix. Extend control on stream to
take an array of values when possible.
Remove name argument from pw_node_new and pw_device_new. We can pass
this as a property instead.
Improve properties on nodes to more closely match what pulseaudio does.
Don't let the monitor do too much with the udev properties but let the
session manager set the description and icon-names.
Remove some change_mask flags for things that don't change in
introspect. Use the flags to mark changes in -cli and -monitor.
Don't free the buffers when the mix is released, this will happen
when nothing is using them anymore with port_use_buffers later.
Mark a mixer as having buffers when the output port has buffers.
Don't set buffers on a mixer port that already has buffers.
Add a new PortConfig parameter to configure ports of elements that
are marked with the SPA_NODE_FLAG_*_PORT_CONFIG. This is used to
configure the operation of the audioconver/audioadapter nodes and
how it should convert the internal format. We want to use the
Profile parameter only for cases where there is an enumeration of
values, like with device configuration.
Add unit tests for audioconvert and adapter to check if they handle
PortConfig correctly.
Make the media session use the PortConfig to dynamically configure
the device nodes.
Remove audio-dsp, it is not used anymore and can/should be implemented
with a simple audioconvert spa node now and some PortConfig.
