Non-English users saw English text in a dozen places and blank labels in
sixteen more.
The English came from sites that produce their copy away from the widget
that renders it, which is what the structural hardcoded-string check
cannot see: picture-in-picture refused with a raw literal instead of the
pipErrors.notSupported key that already existed; the two Jellyfin/Emby
auth throws missing display: rendered their developer message on the
add-server form; ServerParsingException.toString() fed its English into
the localized "Failed to load servers" wrapper; Watch Together
interpolated the whole PeerError, so a failed create read "Failed to
create session: PeerError(PeerErrorType.timeout): Timed out creating
session" and join printed its prefix twice; the hub and playlist
continuation footers rendered exception.toString(); shader rows showed an
English title over an already translated subtitle; the player queue fell
back to the raw Dart enum name; a Plex home user with no title showed
"Unknown"; a failed player start showed "Exception: Failed to initialize
player"; and the tvOS top-shelf header was hardcoded in an extension that
has no Flutter engine.
The blanks came from three recent features that added English keys
without translations. clean_translations.py filled all 21 siblings with
empty strings, so the Android TV resolution switch, every Jellyfin/Emby
recording-rule field, the demuxer row, the Companion Remote address
caption and the Seerr blocklist pill rendered nothing at all.
Two fixes are structural rather than key swaps. ContinuationStatusSliver
now takes an errorContext and calls a new non-logging
localizedLoadErrorText, so no future throw can leak through it. lib/mpv
stays free of user-facing copy: it raises a PlayerInitializationException
sentinel and a PlayerError.playerInitFailed cause tag that the player
screen resolves to localized text. The tvOS section title travels in the
shelf payload, additively, so an older cache still renders.
PlexMediaItem.subtitleMode/extraType were mapped from DTOs and never read (subtype stays — the detail screen's trailer picker destructures it); MediaPlaylist.copyWith, PagedMediaListState.mapItems, isMusicContent/isCollection, and MediaHub.copyWith's eight never-passed params had zero call sites; LiveTvActivityResult wrapped reloadGuide results nobody unwrapped (now Future<void>); PlayerLogLevel.none was unreachable — nothing parses or produces it; MediaSourceInfo.getPartId() was an accessor over its own public field.
ffmpeg's reconnect loop deliberately retries 503 without bound (#1520), so a
server that keeps refusing the stream at open time left a silent black screen:
ExoPlayer fell back to MPV, MPV reconnected forever, and no error ever reached
the screen. A new open-phase watchdog arms on the first 503 seen before any
frame renders and, after 20s without one, synthesizes a server-http-503 error
that shows an actionable dialog. Mid-stream 503s and live TV keep their
existing ride-out paths.
close#1830
A 404 on the media stream means the server resolved the item but could not
open the file behind it — moved, deleted, or on storage that went away.
Jellyfin maps the resulting FileNotFoundException to 404, and PlaybackInfo
never stats the file, so negotiation succeeds and only the stream request
fails. Playback then died with a snackbar reading "Failed to open
[REDACTED_URL]" before popping the route, which tells the user nothing and
leaves nothing useful in a bug report.
Generalize the HTTP-500 log probe into PlayerError.httpStatusFromLog and
latch every status in fatalPlaybackHttpStatuses. Each latches on its own so
the 503 that stream-lavf-o deliberately retries cannot mask the fatal status
behind it. A 404 now raises a dedicated modal naming the cause and the fix.
On Android a 404 previously failed the "Response code: 500" string test and
fell through to the ExoPlayer→MPV fallback, showing "switching to compatible
player" before failing again on the same request. Read the real status off
HttpDataSource.InvalidResponseCodeException instead and skip the fallback:
an HTTP status is not a codec problem.
