Diagnosing capture on a real TV meant reading pactlSources off the
screen and typing an exact PulseAudio source name back in through the
same remote-driven text field — no way to copy-paste, easy to
mistype, and the one piece of information (which source, if any, is
actually RUNNING) was buried in a JSON dump.
Added two choice() pickers bound to the same capture.device setting:
one built from pactlSources (pulse/auto backends), one built from
alsaCapturePcms (alsa backend), both parsed from diagnostics the
service already collects — no new Luna method needed. Diagnostics
already run once at boot, so the picker is populated immediately,
before the user ever presses "Run diagnostics" by hand.
Picking a value writes straight into capture.device, and the plain
text field stays as the fallback for anything the parser misses.

ares-install needs a working ssh into the TV, and this TV only has root
access (no Developer Mode, no ssh currently reachable). The Homebrew
Channel's own "Add repository" dialog accepts any URL that returns
{"packages": [...]}, which is the same schema its own gen-manifest.js
uses per app — confirmed by reading the app's source directly rather
than guessing at the format.
make-manifest.py now also writes out/repo.json, the existing manifest
wrapped in that shape, so publishing is: build the ipk, run the script
with --base-url pointing at wherever the release assets will live,
attach ipk + icon + repo.json there, then paste the repo.json URL into
the TV once. No ares, no ssh, no review queue.
Root elevation afterwards is unaffected either way: "Grant root access"
in the app calls elevate-service over the Luna bus from inside the
running app, which was already ssh-independent.
Corrected two inaccuracies in the process: webosbrew/repo doesn't exist
(the real project is webosbrew/apps-repo), and the Homebrew Channel has
no "install from file" UI — Browse-and-install or the /install Luna
service are the only ways in, both of which need a URL, not a local
path.

The openlgtv NDK is a Linux toolchain with no macOS or Windows build, so
tools/build.sh could not produce a binary anywhere else. docker-build.sh
bakes the SDK into an image and compiles there; packaging and deploy stay
on the host, where the TV is reachable. The SDK ships aarch64 as well as
x86_64, so the image picks the one matching the daemon and Apple Silicon
builds natively rather than under emulation.
Cross-compiling for real turned up three things the host compiler did
not:
sink_hyperhdr_viz.c read p->width and p->height to format the error
message after free(p)
sink_hyperhdr.c an SDP connection line of 128 bytes cannot hold
"IN IP4 " plus a 127-byte host plus "/255", so a
long hostname would silently lose its TTL suffix
common/log.c the log body was sized to the whole ring line,
leaving nothing for the prefix; budget for it so
the bound is provable rather than left to
snprintf
A clean cross-compile is now warning-free, and readelf confirms the
design rule holds: luna-service2, glib, PmLogLib and libc, with no
libpulse or libasound.
Also: @webosose/ares-cli was pinned to ^3.0.0, which does not exist
(latest is 2.4.0), so npm install failed outright. build.sh now puts
node_modules/.bin on PATH so a local install is enough.

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
