Pass the minimum required version to the hook emission and only call
events when the handler is recent enough.
Add some macros to make event emission easier to read.
Make it possible to assign an arbitary node as the port mixer.
Also remove dynamically added ports.
Improve negotiation and allocation on the mixer ports
Add some more SSE optimisations
Move float mixer from the audio dsp to the port
Remove pw_node_get_free_port() and do things more explicitly.
Handle mixer ports in client-node
Keep track of queued data in the stream
Pass delay field around to make it possible to know about the raw
software read/write pointer and the hardware one.
Start stream position at 0
Separate buffer sizes in the info. Make it possible to not set
data pointers for when we use memfd for the memory.
Improve format conversion.
Work on in-place conversion in test-convert2
Make explicit links between elements that are used to activate the
next element in the graph.
Make subgraphs a special regular node. Make a link from the
subgraph children to the parent so that the subgraph completes when
all the children completed.
Implement a single process function in plugins
Remove many messages in the client node
Move the activation state to the graph
Replace an old scheduler with a new one that works with the new
activation states.
Remove the DISABLED port flags, we explicitly add and remove to
make ports enabled/disabled.
Find first compatible port for link
Remove the node based scheduler and use the spa one.
Clang++ (and g++) don't define __STDC_VERSION__ which results in
include/spa/support/log.h:101:5: error: '__STDC_VERSION__' is not defined, evaluates to 0 [-Werror,-Wundef]
#if __STDC_VERSION__ >= 199901L
include/pipewire/log.h:64:5: error: '__STDC_VERSION__' is not defined, evaluates to 0 [-Werror,-Wundef]
#if __STDC_VERSION__ >= 199901L
so check if __STDC_VERSION__ is defined before comparing.
Also, include/feature.h additionally defines __USE_ISOC99 (and
__USE_ISOC11 for C11 extension), so check these as well.
