Confirmed the brightness command applies globally, not per-LED
(serverinfo showed exactly one adjustment object, "id": "default",
covering the whole string), so no LED-count configuration is needed
for this at all -- that question resolved itself once the mechanism
was actually inspected instead of assumed.
For "only react while Spotify is running": only one app can be in the
foreground on webOS at a time, so a "capture the current app" button
in this app's own UI can never work -- pressing it means this app is
foreground, not Spotify. The only workable UI is picking a target from
every *installed* app by name, regardless of what's currently running.
That needed a new native capability this service never had: calling
OUT to another Luna service, not just being called. Two additions:
foreground_app.c subscribes once, at startup, to
com.webos.applicationManager/getForegroundAppInfo
and keeps a thread-safe cache the audio thread can
read without a blocking Luna call
service.c new listApps method, bridging to
com.webos.applicationManager/listApps so the
frontend never has to call another service
directly -- same rule as everywhere else here
Until the subscription has delivered at least one reply, a restricted
sink treats the target app as inactive, not active -- reacting to
audio when the user explicitly restricted it to one app would be the
wrong failure mode. Verified end to end on the host: engine_smoke.c
opens the sink with a restriction set, confirms it reports itself
correctly inactive against the stub Luna bus (which always "fails" to
call out, exactly like a real host with no bus).
Needed real, linkable stub bodies for LSCall/LSCallOneReply/
LSCallCancel/LSMessageGetPayload/LSErrorInit/LSErrorFree
(test/stubs/luna-service2/lunaservice_stub.c) since foreground_app.c
is the first source file here that's actually linked into a host test
binary rather than only syntax-checked -- service.c/main.c's existing
stub declarations were never called, only compiled against. Confirmed
those really are the correct symbol names by cross-compiling clean
against the real webOS SDK's actual libluna-service2, not just the
stub.
Bumped to 1.0.5.

Captures the TV's audio and sends it out over several transports. The
primary one is HyperHDR: RTP/L16 to a host-side loopback device, since
HyperHDR has no network audio input of its own. A second route renders
the spectrum on the TV and sends FlatBuffers images to port 19400
instead, for setups where touching the host's sound config is not an
option.
native/ the service: capture backends (PulseAudio, ALSA, exec,
test tone, all dlopen-based), DSP, and one file per sink
frontend/ D-pad driven UI at a fixed 1920x1080
servicefiles/ native service manifest plus the boot script
host/ RTP receiver and the loopback installer for the HyperHDR
machine
tools/ build/package, asset generation, Homebrew Channel
manifest, on-TV probe
test/ host-side suites: FlatBuffers and RTP verified against
real decoders, the engine end to end, the page in jsdom
