S3 at broadcastmgmt.cloud (RustFS/openresty) returns 403 on range
requests that include an Origin header on presigned URLs. The HMAC
signature only covers 'host' in X-Amz-SignedHeaders, so the browser's
cross-origin Origin header breaks signature validation.
Reverted: /stream and /video no longer redirect to signed S3 URLs.
Fixed: /video now pipes through Node with:
Cache-Control: private, max-age=3600
ETag and Last-Modified forwarded from S3
This means the browser caches video segments for 1h. On seek the
browser checks its cache first — only uncached byte ranges hit the
server. Combined with the 1.5Mbps proxy (was 4Mbps), seeks should
be responsive for clips under ~10 minutes.
- GET /assets/:id/stream now returns a signed S3 URL directly (4h TTL)
instead of pointing to the /video pipe endpoint. Browser streams
directly from S3 — no Node.js bottleneck, S3 handles range requests
natively for smooth seeking.
- GET /assets/:id/video now redirects (302) to a signed S3 URL.
Belt-and-suspenders: any code still calling /video gets redirected.
- proxy.js: default bitrate changed from 10Mbps to 1.5Mbps, audio
default from 192kbps to 128kbps. DB settings already updated to
1.5Mbps. Cuts proxy file size ~6x for the same quality content.
Existing proxies need re-generation at new bitrate.
The badge initially showed '0' before any poll completed. Toggling
display via JS expects an initial display:none so the badge does not
flash in the tab nav on first connect.
Root causes found:
1. Scheduler crashing every 15s: assets table has no error_message column.
Fix: remove error_message from UPDATE in scheduler.js (#66 regression).
2. Clip freezing: client-side filmstrip seek loop runs on main thread,
seeks same proxy the player is streaming → both stall → freeze.
Fix: replace browser seek loop entirely with server-side FFmpeg worker.
3. No dedicated filmstrip worker: filmstrip was never pre-built server-side.
Changes:
- services/mam-api/src/db/migrations/018-add-filmstrip-s3-key.sql
Add filmstrip_s3_key TEXT column to assets table
- services/worker/src/workers/filmstrip.js (new)
BullMQ worker: downloads proxy, runs FFmpeg fps filter to extract
28 evenly-spaced JPEG frames, base64-encodes them, uploads JSON
array to S3 at filmstrips/<assetId>.json, stores key in DB
- services/worker/src/workers/thumbnail.js
Queue filmstrip job automatically after thumbnail completes
- services/worker/src/index.js
Register filmstrip worker (concurrency=2), export filmstripQueue
singleton, close it on SIGTERM
- services/mam-api/src/routes/assets.js
- filmstripQueue added
- POST /reprocess?type=filmstrip now supported
- GET /:id/filmstrip returns signed S3 URL for JSON frames
- services/mam-api/src/routes/jobs.js
filmstrip queue visible in Jobs UI
- services/web-ui/public/screens-asset.jsx
Replace browser seek loop with fetch of /assets/:id/filmstrip
→ fetch S3 JSON → render frames. Zero browser-side video seeking.
Right-click and Files tab re-generate via API endpoint.
- FilesTab: fetch /assets/:id/thumbnail (returns signed S3 URL JSON),
display the resolved URL in <img> instead of pointing directly at the
endpoint which returns JSON not image bytes
- Transcoding: settings updated on ZAMPP1 to gpu_transcode_enabled=false,
codec=libx264 — NVENC not available in worker container (no GPU passthrough)
The proxy worker already has a CPU fallback but this prevents the
unnecessary failed GPU attempt on every job
Two bugs:
1. Frame 0 sets currentTime=0 but probe starts at t=0 after onloadedmetadata,
so 'seeked' never fires (no position change). Promise hangs until the 15s
global timeout kills the whole build. Fix: when currentTime is already at
target (within 0.05s), call done() immediately without waiting for seeked.
2. Seeks into unbuffered regions of large MP4s can stall indefinitely.
Fix: 3s per-frame timeout captures the current decoded frame and moves on,
so a slow/stalled seek doesn't block the remaining 27 frames.
Filmstrip:
- Right-click on the filmstrip opens a context menu with
'Re-generate filmstrip' and 'Re-generate proxy'
- filmstripKey state forces the build effect to re-run on demand
without waiting for a streamUrl/totalMs change
- Context menu dismisses on click, contextmenu, and scroll
Files tab (replaces empty Versions tab):
- Proxy: status badge, S3 key path, inline video preview, re-generate button
- Hi-res master: status badge and S3 key path
- Thumbnail: status badge, S3 key path, inline thumbnail image, re-generate button
- Filmstrip: status badge, frame count, scrollable strip of first 14 frames,
re-generate button (disabled while building)
The /video endpoint requires session auth (requireAuth middleware).
crossOrigin='anonymous' strips cookies from the request → 401 → video
never loads → 15s timeout → filmstrip stays empty for all clips.
Same-origin video does not need crossOrigin for canvas drawImage — the
taint restriction only applies to cross-origin resources.
- Editor: overlay Coming Soon screen over NLE timeline (code preserved,
bumper sits at z-index 100 with backdrop blur). Links to download
ZXP and Windows installer directly from the bumper.
- Settings → Capture SDKs: new Premiere Panel section lists v1.0.0
and v1.0.1 with ZXP + Windows Installer download buttons.
Both releases embedded as static files in web-ui under /downloads/.
- nginx: /downloads/ location serves files as Content-Disposition
attachment with 24h cache.

- #77: await syncToAmpp() with .catch() — no longer fire-and-forget
- #75: migration 016 — add 'proxy','import' to job_type enum; add 'completed' to job_status
- #73: BullMQ orphan job cleanup on hard asset delete
- #70: batch-trim jobs table gets expires_at; trim-status auto-expires stale rows
- #66: scheduler tick marks stale live assets (>2h) as error
- #63: migration 017 — partial unique index prevents concurrent live asset overwrite
- #61: recorders.js uses getS3Bucket() not stale process.env.S3_BUCKET
- #60: already fixed (copy nulls proxy/thumbnail keys, requeues proxy)
- #40: already fixed (All projects clears openProject)
- #64: already fixed (sourceType/needsProxy handled)
- #90: GET /jobs now includes DB jobs table (trim jobs visible in UI)
- #74: nginx Content-Type header preserved; multer 500MB file size limit
- #68: GET /upload returns in-progress ingesting assets
- #58: /stream and /video endpoints fall back to original file for all video types
- #55: recorder poll .catch() logs auth errors cleanly; redirect stops interval

- #50: ProjectCard gets onContextMenu handler with rename/delete menu
- #49: project context menu dismisses on contextmenu + scroll events
Features:
- #93: POST /assets/:id/reprocess?type=proxy|thumbnail — force re-queue any asset
Asset ⋯ menu now shows 'Re-generate proxy' and 'Re-generate thumbnail' buttons
UI:
- Logo: brightness(0) invert(1) filter applied consistently in sidebar, launcher,
and login — white logo pops on dark UI; inline style removed from login.html
track?.@_currentExplodedTrackIndex is invalid JS syntax — @ is not a
valid identifier character. Replaced with track?.['@_currentExplodedTrackIndex']
so the worker process no longer crashes on startup.
Four critical fixes:
- Remove overflow:hidden on tlRef so Timeline.init's scroll survives re-renders
- Don't call _renderClips() inside mousedown (was destroying event target mid-drag)
- Use refs for undo history to eliminate stale closure in onClipsChanged callback
- Change .tl-clip-area overflow:hidden to overflow:visible so pointer events reach clip edges
