7 - is a gstreamer appliation
8 - open physical sink, src elements
9 - prepends an adder to sinks
10 - appends an tee to sources
11 - listens to dbus, to get notified by virtual-endpoints of init/finalize
12 (the dbus notify, would also be useful for gst-editor to hook on running
16 - virtual-audiosink, virtual-videosink
17 virtual-audiosrc, virtual-videosrc
18 - virtual sinks establish a connection to the daemon
19 - they link to request_pads of the adder/tee elements
20 - on init and finalize they send a dbus-message
23 - lists instances as mixing-desk like channelstrips
24 - channelstrips would contain
26 - volume, panorama, 3-band eq
28 - brightness, contrast, alpha-level
31 - route channel to targets, where targets can be real sinks or more
32 virtual-sinks (sub-groups)
33 - virtual sinks need queues to decouple application processes
36 - expose child-elements via child-proxy
37 - then e.g. the applications volume-control could directly access the
39 - state-control (play, pause/mute)
40 - it would be useful if one app could pause/mute others
41 - think of a voip-client, if there is an incoming call, if pauses your
42 media-player, or mutes the monitoring of your recording app
