Implement setting graph properties
Provides a unified property setter method based on the same graph tree syntax.
Quite simply to change the volume of a node:
pipewire-0>>graph 32/info/params/Props/volume=0.8
remote 1 node 32 changed
pipewire-0>>graph 32/info/params/Props
volume: 0.800000
mute: true
channelVolumes: []
For now only modifying the volume and mute state is supported but other setters will be forthcoming later.
