The helper now observes dwidth/dheight and renders its FBO at the
aspect-fit size of the video inside the requested viewport, bumping a shm
generation on change — letterbox bars are never baked into frames (the VOD
watch shell's ~2:1 box no longer shows black side bars; the canvas
background is transparent so the sides show the app surface, while
fullscreen keeps its black backdrop). Frames also get smaller than the
viewport when aspects differ, trimming copy cost. Aspect override changes
refit automatically. Snapshots now carry videoWidth/videoHeight, and the
adapter forwards IPTVNATOR_EMBEDDED_MPV_AUDIO_DELAY to mpv's audio-delay
for lip-sync tuning until proper calibration lands.

iptvnator_mpv_helper: one-process-per-session libmpv host that renders
offscreen at viewport size (headless CGL + async PBO ring, validated in
spikes/mpv-frame-copy), publishes BGRA frames into a seqlock shm ring with
resize generations, plays audio directly, and speaks a stdio protocol —
tab-separated commands in, JSON events out. The snapshot event mirrors
NativeEmbeddedMpvSessionSnapshot; status semantics (END_FILE reasons,
eof-reached with keep-open, pause gated on loaded path, fatal-only status
flips) are ported from embedded_mpv.mm.
embedded_mpv_frame_reader.node: plain-C N-API reader the preload script
uses to memcpy the newest complete frame into a V8 ArrayBuffer (Electron's
memory cage forbids zero-copy). Stub exports off macOS.
Both build as extra binding.gyp targets through build-embedded-mpv.js; the
helper gets the same libmpv dependency-path rewrite + ad-hoc re-sign as the
addon and is validated by the forbidden-link check.

* fix(playback): harden embedded mpv session handling and support detection
- guard the session controller against late startup rejections clobbering
a newer session during fast channel zapping
- exclude the refresh timestamp from the session-update dedup key so idle
sessions stop re-emitting IPC updates every 500 ms
- macOS: reconcile async loadfile replies by request id so a rejected
seek/aid/speed on a live stream no longer flips the session to error
- append --ozone-platform=x11 on Linux in main.ts so direct binary and
AppImage launches match the packaged .desktop launcher behavior
- return a sandbox-specific unsupported reason in Flatpak/Snap instead of
asking the user to install mpv inside the sandbox
- update the stale "macOS only" embedded MPV claim in CLAUDE.md

* feat(playback): populate Linux audio tracks and fix ARM Linux packaging
- Linux poller now reads track-list/count each tick and walks the scalar
track-list/N/* sub-properties when the count changes, so the audio-track
menu is no longer empty; selection reconciles from the aid property
- afterPack replaces the x64 embedded_mpv.node with an
embedded-mpv-unavailable.txt marker in arm64/armv7l Linux packages, and
package-layout verification rejects foreign-architecture addons while
requiring the marker
- extend native source invariants for the non-fatal async-reply rule
(macOS) and the Linux track-list polling contract
- document the Linux track-list mechanics and ARM packaging behavior in
docs/architecture/embedded-mpv-native.md

* feat(playback): embedded mpv player UX polish and full localization
- click on the video toggles pause (same action as Space) with a 250 ms
grace period so double-click fullscreen cancels the pending pause; no
DOM overlay is drawn — the dock transport icon is the feedback
- timeline scrubbing previews the drag position locally and commits a
single seek on release instead of one IPC seek per drag pixel
- translate all player UI strings (controls, tooltips, aria-labels,
status and recording messages) via new EMBEDDED_MPV.PLAYER.* keys,
synced across en + 17 locales through the i18n-fill workflow
- replace the legacy @Output() EventEmitter with the signal output() API

* fix(playback): react to language changes and respect ozone platform hint
Address review feedback on #1122:
- add a translationsTick signal (onLangChange/onTranslationChange/
onDefaultLangChange) read by every computed() and template helper that
calls translate.instant(), so labels re-evaluate on a runtime language
switch and when the translation file finishes loading after mount
- suppress the Linux --ozone-platform=x11 fallback when the user set
ELECTRON_OZONE_PLATFORM_HINT, matching the existing respect for an
explicit --ozone-platform switch

Adds experimental embedded MPV support for Windows and Linux, expands packaging/runtime validation, and updates CI coverage for the cross-platform native addon.
The renderer was reading session.id and forwarding it to the addon, but
during the loading window that id is the placeholder
"embedded-mpv-starting" set by createLoadingSession. If the user adjusted
volume, seeked, or toggled audio/subtitle/speed/aspect before the addon's
createSession returned the real id, that placeholder id reached the
addon — and the addon's getSessionOrThrow threw a raw std::runtime_error
which libc++abi terminated the process on.
Two fixes, defense in depth:
1. Renderer (session controller): use the canonical sessionId() signal,
which is null until the addon hands back a real id, as the gate for all
IPC calls. Wrap every IPC call in a guardIpc helper that swallows
addon-side throws so a torn-down session or race won't surface as an
uncaught promise rejection.
2. Native (embedded_mpv.mm): change getSessionOrThrow to take a
Napi::Env and throw Napi::Error::New(env, ...) instead of
std::runtime_error. node-addon-api converts Napi::Error to a JS
exception cleanly; the previous std::runtime_error escaped the C++
frame and aborted the process when the addon was built without
NAPI_CPP_EXCEPTIONS translation. Refactor splits findSession (returns
nullptr) from getSessionOrThrow (env-aware) so call paths that just
probe a session's existence don't pay the throw cost.
The native fix needs an addon rebuild to take effect; the renderer fix
prevents the crash trigger immediately.

Native addon (apps/electron-backend/native/src/embedded_mpv.mm)
- Extend SessionSnapshot with subtitleTracks, selectedSubtitleTrackId,
playbackSpeed, aspectOverride.
- Refactor track parsing into a shared updateTracksFromNode helper that
filters by mpv "type" so audio and subtitle tracks share the code path.
- Observe sid, speed, video-aspect-override; clear sub state on
MPV_EVENT_START_FILE.
- Export setSubtitleTrack (handles trackId === -1 as "no" to disable),
setSpeed (clamped to 0.25–4.0), setAspect (passthrough string for
video-aspect-override).
- Snapshot output now includes the new fields.
Service (embedded-mpv-native.service.ts) + IPC + preload
- Mirror methods on EmbeddedMpvNativeService with capability detection: each
method throws a descriptive error if the loaded addon doesn't expose the
underlying native function (i.e. user is running an older build).
- New IPC channels EMBEDDED_MPV_SET_SUBTITLE_TRACK, _SET_SPEED, _SET_ASPECT
registered in events file and exposed via preload.
- Extend EmbeddedMpvSupport with a capabilities probe so the renderer can
hide controls for features the current addon build doesn't ship.
Renderer (embedded-mpv-player.component.{ts,html})
- Three new popovers anchored above their buttons (subtitle / speed /
aspect), gated by capabilities() and (for subtitles) by track count.
- Subtitle popover includes an Off entry; speed/aspect use fixed presets.
- Error state now surfaces the same overlay as the stalled state, with a
Retry button that bumps the existing retryNonce signal — covers #8 from
the audit.
- All session-payload defaults (loading stub, error stub, refresh fallback,
dispose payload, native createSession default) updated for the new
required fields.
NOTE: Existing addon binaries do not expose the new methods. Until the
addon is rebuilt (pnpm run serve:backend:embedded-mpv or the release
build script), capabilities will report subtitles/playbackSpeed/
aspectOverride as false and the new buttons will simply not appear.
