Live TV channels in Xtream playlists go blank whenever the provider's
get_short_epg returns nothing, even when the user has working XMLTV
URLs in Settings. The XMLTV pipeline already populates epg_programs
but only the M3U module was reading it.
Wire those uploads up as a fallback for Xtream too: when the provider
returns nothing for a channel with an epg_channel_id, look it up in
the local table. A settings toggle flips the priority for users whose
curated XMLTV is better than the provider's auto guide.
EpgQueueService.enqueue() became async to batch the XMLTV lookup once
per viewport change. To keep the queue consistent under fast scroll,
all shared-state mutations now happen behind a generation counter so
only the latest call commits. Per-method bridge gating in the new
XtreamXmltvFallbackService keeps each path working when the preload
exposes only one of the two endpoints.
Covers the embedded MPV player on macOS, toggleable Live TV sidebars,
command palette upgrades, and module fixes. Credits the Telegram tip

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.

VLC was unconditionally spawned per click — VLC's own single-instance
preference fails because the per-launch RC args defeat its D-Bus
forwarder. Mirror the existing MPV reuse pattern so users can opt in to
driving one tracked VLC via its RC interface (clear + add) instead of
opening a new window every stream.

The embedded MPV player renders via libmpv into a custom Cocoa view, which
bypasses mpv's built-in screensaver inhibition. Hold an Electron
powerSaveBlocker (prevent-display-sleep) while any session is playing and
release it on pause, dispose, or shutdown.

- Introduced new localization keys for Xtream refresh actions in multiple languages (ar, ary, by, de, el, en, es, fr, it, ja, ko, nl, pl, pt, ru, tr, zh, zhtw).
- Implemented refresh preparation state management in PlaylistRefreshActionService.
- Enhanced WorkspaceShellXtreamImportService to handle refresh preparation states and display appropriate labels.
- Updated tests to cover new refresh preparation scenarios and ensure correct overlay display during refresh operations.

Three first-paint fixes for cold app start.
#1 — Inline splash in index.html
Cold start used to show a blank Material-grey background until the
~1.5MB preloaded chunk + 300KB styles.css downloaded and Angular
bootstrapped. On slow disks/networks that's 1-3+ s of "is the app
frozen?" before any pixel of UI appears.
Add a self-contained splash (inline CSS, no extra HTTP, no assets) —
"IPTVnator" wordmark + a CSS spinner — that paints immediately from
the parsed HTML. Removed in main.ts after bootstrapApplication()
resolves, gated on requestAnimationFrame so the swap happens after
AppComponent's first paint (no flash of empty background between
splash removal and the real UI).
Respects prefers-reduced-motion (spinner stops, opacity dims).
#3 — Drop legacy `global = window` polyfill
The inline <script> in <head> ("if (global === undefined) var global =
window") was a workaround for an older library expecting Node's
`global`. Verified nothing in the current bundle reads window.global
(the only matches are TypeScript `declare global { ... }` blocks and
unrelated route paths). Removes one render-blocking inline <script>
parse from the critical path.
#5 — Synchronous language hint
Settings live in IndexedDB (via @ngx-pwa/local-storage), which the
TranslateModule cannot read synchronously at bootstrap. So the first
render historically used English regardless of the user's preference,
then re-rendered every TranslatePipe in the tree once initSettings()
finished — visible flash for non-English users.
Mirror the active language to localStorage in initSettings() once the
IDB-backed settings resolve. Add getInitialLanguage() in app.config.ts
that reads that key synchronously before bootstrap and passes it to
TranslateModule.forRoot({ defaultLanguage }). First-ever boot still
falls back to English (no hint yet); every subsequent boot renders in
the saved language from the very first frame.
