With the new playback setting enabled, episode advance carries no audio or
subtitle preference at all, so both resolve from the streams selected on
the server for each individual episode. This serves setups that curate
selections server-side (e.g. Plex Auto Languages) and is independent of
"Remember track selections", which keeps gating only the write-back of
manual changes.
close#1717
The sheet collapsed an item to `Media.first` / `MediaSources.first` and
rendered a fixed set of rows, so split files, extra versions, per-track
properties, HDR classification and Dolby Vision were all invisible.
Model the payload the way both servers shape it — versions own parts,
parts own streams — and project every property either backend populates
onto `MediaStreamDetails`. The field set comes from sweeping both test
servers in full through the clients' own request shapes (Plex 6842
Media / 6842 Part / 39864 Stream entries, Jellyfin 6349 sources / 37763
streams / 61224 attachments), so file presence, Dolby Vision layers,
dynamic range, sample rate, spatial audio, sidecar provenance, embedded
attachments, rotation and the lyric stream type all survive. A coverage
test fails when a server key is neither carried, folded into a sibling,
nor excluded with a reason.
File Info also stopped trusting the shared `/library/metadata/{id}`
cache row: `getPlaybackExtras` writes it without `includeStreams` /
`checkFiles`, so the sheet could render with no stream table at all.
Detect that shape and refetch once under the request context captured
before the cache read, so the outgoing token and the cache namespace
stay on one profile.
Rework the layout to match: a summary chip row, then flat tonal cards
with a two-column field grid that collapses to one column on narrow
viewports, per-stream cards with flag chips, and a copyable monospace
path row. The card fill is a tonal step off the text colour rather than
the `bg` token, which is one shade from the sheet surface on OLED.
`clean_translations.py --strict` reported seven unused keys.
Three are genuinely dead: TrackSelectionHelper.getEmptyMessage was
removed as unreachable in 4307c49c, and the sheets that need an empty
state carry their own strings. Removes them from every locale.
The four accessibility keys are false positives. tv_number_spinner
aliased the subtree as `final a11y = ...accessibility`, which the static
scanner cannot follow — its docstring says as much. Binds the documented
`final t = Translations.of(context)` instead and hoists the two labels,
so the semantics stay identical and the scanner sees the chains.
Groundwork for #1300. Establishes the session, buffering and route
handling Dolby's application guide prescribes, and adds the diagnostic
arm needed to find out whether Apple's sample-buffer renderer can carry
Atmos objects at all.
Audio session, per the guide's sequence:
- Adopt the long-form playback profile in one atomic call at app launch
and activate the session there. The SDK only accepts that policy with
category Playback, a Default/MoviePlayback/SpokenAudio mode and no
options, so it cannot be assembled from separate calls.
- Report the resolved rendering mode in the player, hidden unless the
system resolves it. Apple only resolves it for CarPlay and AirPlay, so
an unresolved value means unknown, never "not Dolby".
Diagnostics (Apple TV only, Settings > Video Playback > Atmos Output Test):
- Add a sample-buffer arm. It reads the asset with AVAssetReader at
outputSettings nil and hands the untouched compressed buffers and the
untouched format description straight to the renderer, with a variant
that rebuilds the description the way playback builds it. Every
existing mode went through AVPlayer, so nothing exercised the path
playback actually uses; this is what tells us whether the renderer or
our construction is at fault.
- Add an AirPlay route picker. AirPlay is the only route where the system
resolves the rendering mode and the supported channel layouts, so it is
what makes those observations reachable at all, and the AVPlayer arms
now allow external playback so every arm can be compared on the same
destination.
- Add a session-mode toggle for the one profile difference between the
guide and previous playback behaviour.
- Report the session profile, supported layouts, both format
descriptions, the magic cookie and the renderer status, and release the
session on stop so a failed run cannot contaminate the next one.
Also bumps MPVKit to 1.0.14, which carries the matching audio output
work: the channel layout AVFoundation itself uses for Dolby content, a
renderer-failure observer so the fallback to PCM can actually run, the
prescribed feed ordering and preroll, flush recovery that re-supplies the
discarded audio instead of shifting later audio into its place, and
capability-driven fallback on route and capability changes.
This does not yet fix#1300. Whether the sample-buffer renderer can carry
JOC is still unknown; it removes every difference from the documented
setup that could explain the failure, and gives us the arm to answer it
on real hardware.
Complete and revise every shipped locale against the current English source, preserve locale-specific plurals, and map script-specific Chinese locales through device, Intl, duration, and Plex boundaries.
