Tested against a real HyperHDR instance rather than trusting the
schema further. scaleOutput (from the current schema-adjustment.json)
produced no visible change and no trace in serverinfo's echoed-back
adjustment state. brightness (0-100, absent from that same schema)
round-tripped correctly through serverinfo and visibly dimmed real
LEDs -- confirmed live, with piccap as the sole colour source and
only this sink's JSON-RPC calls changing anything.
A schema documents what a command accepts; it does not guarantee
what a given build actually does with each field, and this is a
mismatch between HyperHDR's current dev-branch schema and whatever
build the target instance is actually running. Switched the sink to
brightness (int 0-100) throughout: wire format, config defaults
(minBrightness/maxBrightness, 20-100), status fields, and the reset
sent on close. Renamed the frontend fields and mock to match.
Cross-compiles clean. Bumped to 1.0.4.

Every existing HyperHDR route replaces whatever else is on the LEDs:
routes 1/2 hand HyperHDR's own audio effect a device to read, route 3
sends a synthetic spectrum image, and both take over via HyperHDR's
priority system. For a setup that already has a real colour source
(a screen grabber, a USB capture card) feeding an ambilight-style LED
run, none of that is what's wanted -- the colour should stay put and
only brightness should react.
Read HyperHDR's own source (sources/api/JSONRPC_schema/schema-adjustment.json)
rather than guess: "adjustment" is a post-processing command with a
scaleOutput parameter (0-2.0) that applies regardless of which
priority is currently active. Confirmed the wire format too --
sources/jsonserver/JsonClientConnection.cpp frames it as plain
newline-delimited JSON over TCP (default port 19444), nothing like the
length-prefixed Flatbuffers protocol the visualiser sink speaks, and
with no handshake or registration needed before the first write.
sink_hyperhdr_adjust.c sends only that: no image, no priority, so it
never competes with an existing grabber. Non-blocking connect with the
same poll()+SO_ERROR pattern net/hyperion.c already uses, reconnects
every 5s, rate-limited to 20 Hz (a HyperHDR command every audio block
would be pointless flooding), and resets scaleOutput to 1.0 on close
rather than leaving the LEDs stuck at whatever it last sent. Cross-
compiles clean under -Wall -Wextra on the real webOS toolchain.
Wired through the same path every other sink follows: registered in
sink.c/sink.h, defaults in config.c, fields in frontend/js/app.js
(SINK_FIELDS/SINK_HELP), mock.js and ui_smoke.js updated for the new
sink card. Bumped to 1.0.3.

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.
