Bring the GameStream/Moonlight plane up to the native plane's capability parity.
HDR (Windows only):
- New host_hdr_capable() gate (Windows + PUNKTFUNK_10BIT, matching the native
policy). serverinfo layers SCM_HEVC_MAIN10 onto the probed/static codec mask, so
Moonlight finally offers its HDR toggle (live: mask 0x10101 -> 0x10301).
- Parse the client's dynamicRangeMode into StreamConfig.hdr and pass it through to
OutputFormat::resolve, so a client HDR request proactively enables advanced color
on the per-session virtual display (PQ flows even from an SDR desktop). The
encoder bit depth now derives from the captured frame format (gs_bit_depth) rather
than a hard-coded 8 that mislabeled the already-Main10 HDR stream.
Game library in /applist:
- The catalog now layers library::all_games() (Steam/Epic/GOG/Xbox/custom) on top of
Desktop/apps.json, each with a STABLE GameStream id (FNV-1a, dedup-probed) and the
store-qualified library id. Launch routes through the existing security-reviewed
launch_title/launch_command via library::launch_gamestream_library — a client can
only pick an existing title, never inject a command.
- /appasset cover proxy: Moonlight fetches per-app covers from the host, so resolve
appid -> library cover URL and proxy the bytes (portrait -> header -> hero -> logo;
data: + bounded http(s) fetch), on a blocking thread. IsHdrSupported reflects the
host HDR capability.
4:4:4 stays off on GameStream by design: stock Moonlight is 4:2:0 and the Windows
IDD-push capturer can't deliver full chroma yet (capturer_supports_444() == false);
the gate is documented so it lights up once IDD-push full-chroma capture lands.
Validated live (Moonlight -> Windows NVENC host): HDR advertised, the Epic library
shows with covers, launch works. clippy clean; apps/serverinfo/library unit tests
cover the HDR mask, stable-id, dedup, and data-URL paths.
