CEP's embedded Chromium (used by Premiere Pro panels) does not support
oklch() color syntax. All color tokens were rendering as invalid/transparent,
causing the panel to appear unstyled. Converted all oklch() values to their
precise hex/rgba equivalents via OKLab→sRGB math. No design changes.
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.
End-to-end debugging against a live Premiere Pro 2025 + auth-enabled mam-api
surfaced four real bugs that made v1.0.0 install cleanly but never load,
plus the missing auth flow. All four are fixed and the panel is verified
connected (status dot green, Reconnect button shown, project list populated).
- manifest.xml: a comment in the <Resources> block contained "--" (inside
"--enable-nodejs"/"--mixed-context"), which is illegal per the XML spec.
CEP 12's strict parser logged
ERROR XPATH Double hyphen within comment
and skipped the panel entirely. Comment rewritten without double hyphens.
- manifest.xml: lacked the Version="X.Y" attribute on <ExtensionManifest>
and used a non-standard AbstractionLayers/empty <ExtensionList/>
structure. CEP rejected it with
Unsupported Manifest version ''
Manifest rewritten to the standard CSXS 7.0 schema (ExtensionList +
DispatchInfoList + RequiredRuntimeList), matching the working AMPP
panel template.
- main.js: re-declared `const csInterface = new CSInterface()` at top
level even though CSInterface.js already declared the same binding.
CEP 12 shares script-realm lexical scope across <script> tags, so the
second const threw
Identifier 'csInterface' has already been declared
The throw fired before setupEventListeners(), so the Connect button's
click handler was never attached. This is the root cause of the
original "clicking Connect does nothing" symptom; everything else was
secondary. Removed the duplicate declaration; main.js now uses the
binding from CSInterface.js.
- No auth support against AUTH_ENABLED=true servers. mam-api supports
Bearer tokens (POST /api/v1/tokens), so added:
• API token input field (password-masked) next to Server URL
• localStorage persistence on every keystroke
• window.fetch monkey-patch that injects
Authorization: Bearer <token>
on every request whose URL starts with the configured server.
Signed S3 download URLs are NOT touched.
Drive-by fixes that came out of the same debugging pass:
- Server URL input listener was 'change' (fires on blur); switched to
'input' so typing-then-clicking-Connect immediately commits.
- restoreSettings() now strips trailing slashes from the stored URL so
older saved values like 'http://host/' stop producing //api/v1 404s.
- CSS selector `input[type="text"].server-url` didn't match the new
password input → the token field was unstyled and effectively invisible.
Generalized to `input.server-url`; restructured the connection bar into
`.connection-controls--stacked` (flex column) of two `.server-input-row`
rows so two input fields fit cleanly.
- Build scripts now parse ExtensionBundleVersion from both element form
(<ExtensionBundleVersion>X</...>) and attribute form
(ExtensionBundleVersion="X"), since the manifest rewrite switched
schemas.
Version bumped 1.0.0 → 1.0.1. New artifacts committed at
services/premiere-plugin/build/releases/v1.0.1/ (.exe 2 MB, .zxp 35 KB).
v1.0.0 left in place so editors who downloaded it can verify they're on
the broken version.
