- online.rs: on Linux, advertise only WebView-decodable codecs (h264 video;
aac/mp3/opus/vorbis/flac audio) in PlaybackInfo so Jellyfin transcodes
HEVC/AV1/VP9/etc. to h264 HLS for the WebKitGTK <video> element.
- player: on Linux, don't load video into MPV (no embedded window — it would
start a redundant decode the frontend immediately stops). Add
PlayerController::set_current_item to keep queue/UI/remote-transfer state in
sync without loading the item into the playback backend.
- Add #[specta::specta] to all 201 #[tauri::command] functions.
- Derive specta::Type on all IPC DTOs (repository/types, settings, player/storage/
download command DTOs, player enums, jellyfin SessionInfo/NowPlayingItem/PlayState,
ThumbnailCacheStats, DownloadInfo, CacheConfig, etc.).
- Replace tauri::generate_handler! with a tauri_specta::Builder + collect_commands!
in lib.rs (exports bindings.ts in debug builds).
Two contract changes required by specta constraints (frontend migration follows):
- specta caps command arity at 10 args: download_item_and_start / download_item /
download_video now take a single request struct (params bundled, body unchanged
via destructuring).
- specta can't parse split serde rename_all: SessionInfo/NowPlayingItem/PlayState
switched to rename_all = "PascalCase" (Jellyfin deserialization preserved; these
now serialize PascalCase to the frontend).
cargo check --lib is clean (0 errors). Frontend migration to bindings.ts is the next step.
Workstream A — poison-tolerant locking:
- Add utils/lock.rs with MutexSafe/RwLockSafe extension traits that recover a
poisoned std::sync lock instead of panicking, plus unit tests.
- Replace all 153 .lock().unwrap() and 4 .read()/.write().unwrap() production
sites with _safe variants across 14 files, eliminating the player
crash-cascade class. Tokio async mutexes are unchanged.
Workstream B — graceful backend init:
- create_player_backend no longer panics when MPV/ExoPlayer fail to initialize;
it falls back to NullBackend and emits a backend-init-failed event so the UI
can show "playback unavailable" instead of the app crashing. Fatal DB-setup
panics are kept.
Workstream F — doc reconciliation:
- Rewrite software-architecture.md's inaccurate "thin UI / ~800 lines" claims to
reflect reality (~20.5k non-test frontend) and document the events+polling
hybrid plus the new locking/backend-init behavior.
