The server's `playable` flag is computed Chromium-first, but HEVC
web-playability is browser-dependent: WebKit (Safari on macOS/iOS) decodes
HEVC via the OS while Chromium/Firefox/Electron can't. Treating the flag as
global wrongly showed Safari users the download fallback for files they can
play inline.
The client now treats `playable === false` as "needs a capability check": it
pre-renders the fallback only when the current browser also can't decode the
format, gated on a one-time canPlayType probe (BROWSER_SUPPORTS_HEVC). Capable
browsers attempt inline playback; the <video> onError handler remains the
safety net for genuine failures.
macOS screen recordings are HEVC inside a .mov container, which Chromium,
Firefox and stock Electron can't decode. The file uploaded fine and a
server-side ffmpeg poster was generated, but inline <video> playback failed
silently — stuck at 0:00 with no error, since AttachmentRenderer had no error
handling. Root cause: the system had no concept of web-playability.
Server detects, client degrades:
- mediaPlayable.ts: classifyVideoPlayable(mimetype, codec) — tri-state
(false = known-undecodable e.g. HEVC/ProRes, true = web codec in web
container, null = unknown/optimistic). Never widens `false` beyond codecs
that fail everywhere, so ffmpeg-less instances keep prior behaviour.
- probeMediaMeta now captures the video codec_name; the upload finish hook
stores the verdict in the new attachments.playable column (migration 0007).
- Flag propagated through every serializer: space messages, DMs, WS, and
federation relay (outbound + inbound) — federation-compatible.
- VideoAttachment component: playable===false renders a download card (poster
+ "Can't play here — download" + name/duration/size) with no dead-player
flash; otherwise plays inline with an onError fallback to the same card.
Specs updated: uploads.md, database.md, federation.md.
Adds an admin-driven sweep on top of the existing 24h auto-expire so
operators can see and reap abandoned `.tus/` sessions without waiting.
- storageJanitor: extract `walkTusDir(predicate)` helper, add
`getStaleTusInfo` + `cleanupStaleTusSessions(thresholdMs, dryRun)`;
refactor `cleanupTusStragglers` to delegate while preserving its
janitor-tick `{ removed }` contract.
- StorageStats gains `staleTusSessions` + `staleTusSize` (fixed 1h
display threshold).
- New `POST /api/admin/storage/cleanup-tus` route with
`maxAgeHours` validation (positive finite number, default 1) and
`dryRun` support; admin-gated.
- StoragePanel: 6th overview card "Stale Uploads" + new cleanup
subsection mirroring the media-cleanup pattern (preview-then-clean
with shared result panel styling).
- Tests: 8 new janitor tests covering empty dir, threshold filtering,
dry-run vs live, oldest-mtime tracking, subdir skipping, and the
override path on the existing straggler sweep. New
`routes/admin.test.ts` covers auth/admin gates, validation (zero,
negative, NaN), default `maxAgeHours`, dry-run vs live unlink.
- Docs: `uploads.md` §Janitor expanded to the full lifecycle (cancel
DELETE, discard DELETE, auto-expire, straggler sweep, admin route);
`admin.md` Storage Management updated with the new endpoint and
StorageStats fields.
