A collections page fires 100+ concurrent poster requests. Both image proxies
(/image and /person-image) authenticated via current_user + Depends(get_db),
holding a pooled DB connection for the whole request — including the slow Plex/
CDN fetch. Under the burst, the 15-connection pool was exhausted → QueuePool
checkout timeouts → 502s → slow, partially-loaded grids on prod.
Fix: authenticate these two high-fan-out endpoints with a signed-session check
(no DB user-load), serve disk-cache hits with zero DB access, and on a cold miss
open a short session only to resolve the image key + Plex config, releasing it
BEFORE the fetch (image_bytes uses no DB). Also raise the pool (20 + 30 overflow)
as headroom above the sync-endpoint threadpool.
Derive a `source` bucket per collection from the already-synced title + smart
flag (no schema change, no re-sync): external list providers (IMDb/TMDb/TVDb/
Trakt) by leading token, Plex smart lists via the smart flag, everything else a
genuine "collection". Returned on each info-page collection strip so the client
can show/hide each type independently. Adds the stripSource labels (en/hu/de).
Backend (migration 0047_plex_collections): a plex_collections table mirrors every Plex
collection (card metadata + smart flag + an editable flag reserved for Phase 2); membership
is stored as GIN-indexed collection_keys on member movies (plex_items) and shows (plex_shows).
The background sync (plex_sync) now fetches each library's collections + their children and
rebuilds membership — so ALL reads are local (Plex's dual-language collection queries are slow;
this trades a ~4-min background sync for instant reads). New /api/plex/collections endpoint;
/browse gains a combinable filter; item_detail returns the movie's collection
'strips' (sibling titles as playable cards, smallest/most-specific collection first) — all pure
local lookups.
Frontend: PlexSidebar gains a searchable Collection picker + an active-collection chip;
PlexInfo renders the collection strips (playable posters + 'Browse collection' → sets the
filter); the collection is part of PlexFilters (persisted). i18n en/hu/de.
Phase 2 (create/edit collections with write-back to Plex) is separate.
Backend (migration 0046_plex_people_search): a new people_text column (cast +
director names, de-duped) is folded into the generated search_vector at weight B,
so the top search box finds titles by an actor/director name and ranks them above
summary-only mentions. New /api/plex/people endpoint returns the cast/crew matching
the term (name prefix or word-start) with a film count + a headshot (pulled from one
representative film's live metadata; image bytes disk-cached).
Frontend: PlexBrowse shows matching people as virtual cards above the grid; clicking
one adds them to the actor/director filter (multi-value, from the C1 work) and clears
the search box so you land on exactly that person's films. Answers the 'why does
"drew" match Rambo?' confusion — it was matching the word in the synopsis; now names
are searchable. i18n en/hu/de.
⚠️ Prod needs a Plex re-sync after deploy to populate people_text (search_vector
regenerates automatically once the column has data).
UAT follow-ups on the Plex filter epic:
- Sort now has an asc/desc toggle (sort_dir), applied to any sort field.
- Genre multi-select gains an Any/All mode (genre_mode: OR vs AND containment).
- Director/actor/studio become multi-value: people AND (titles featuring all selected),
studios OR; clicking them on the info page stacks (unions) instead of replacing, and
the sidebar shows each as a removable 'Active' chip.
- fix(history): clicking a metadata filter on the info page now pushes a fresh grid
entry instead of history.back(), so browser Back returns to the info page rather than
leaving the Plex module.
- fix(player): fully tear down the <video> + hls on unmount and guard late play() calls,
so backing out of a just-started video no longer leaves audio playing in the background.
i18n en/hu/de (match any/all, sort direction).
Backend (migration 0045_plex_filter_meta): plex_items gains rating (audienceRating
~IMDb), content_rating, studio, originally_available_at, and GIN-indexed genres /
directors / cast_names — all mirrored from the cheap section listing (no per-item API
calls; they also seed a future watch-habit recommender). /browse gains genre / content-
rating / year / rating / duration / added-within / director / actor / studio filters
(@> containment, GIN) + sort by year|rating|duration|release; new /facets endpoint
returns available genres+ratings (with counts) and the year/rating/duration bounds. A
thin on-disk image cache (.plex-img-cache) serves posters/art/cast photos from local
disk after first fetch (~7-14x faster repeat loads).
Frontend: PlexSidebar grows the full filter set (facet-driven genre/age chips, rating
steps, year range inputs, duration buckets, added-within, active people/studio chips,
clear-all); filters persist per-account as one JSON blob. PlexInfo metadata (year,
genre, director, cast, studio, IMDb score) is clickable → sets the matching filter and
returns to the filtered grid (page variant only; the in-player overlay stays read-only
so a stray click can't stop playback). i18n en/hu/de.
Backend (no migration): item_detail now also returns IMDb score + id/url (from the
Plex Rating/Guid arrays), content rating, genres, director(s), studio, tagline, and
cast as {name, role, photo}. New host-whitelisted /person-image proxy serves cast
photos from Plex's public metadata CDN (keeps third-party requests off the browser).
Frontend: reusable PlexInfo component in two forms — a full info page opened from a
card's 'i' button (history subview, art backdrop, Play/Resume + watch controls) and a
lean overlay in the player toggled with 'I' (video keeps playing). Two per-user view
prefs (faint backdrop, cast row) persisted in preferences. Mark-unwatched / clear-resume
cover the watched-reset gap. i18n en/hu/de.
Extend admin POST /api/plex/test to resolve one real media file through the
local mount (a mirrored sample, else a single leaf fetched from Plex) and report
whether it is readable. A missing media bind-mount or a wrong plex_path_map is
now caught at Test time rather than only surfacing later as a dead player.
Backend: item detail returns audio_streams + subtitle_streams (from Plex Part.Stream
ordinals). The HLS session accepts audio/subtitle stream ordinals — the selected audio
is mapped (transcoded to AAC), a selected subtitle is muxed in as a WebVTT rendition
via a MASTER playlist (-master_pl_name + -var_stream_map sgroup:subs) so ffmpeg keeps
it in sync per-session. Selecting a track forces the HLS path (even for direct files).
Generic /stream/{rk}/hls/{filename} endpoint serves the master/media/vtt/ts artifacts.
Frontend: gear menu lists real audio + subtitle tracks; changing one restarts the
session at the current position (seek-restart mechanism). hls.js subtitle enabled on
SUBTITLE_TRACKS_UPDATED (not just MANIFEST_PARSED, else the VTT is never fetched).
Cues auto-nudged to line 88% (the full-height <video> clips a default bottom-edge cue).
Controls no longer auto-hide while the menu is open. plex.player.* i18n en/hu/de.
Verified in a real browser (2 Broke Girls S1E1, 2 audio + 2 subs): menu shows the real
tracks, enabling English subtitles renders them correctly positioned; backend master
playlist + vtt segments validated over HTTP.
- Player: control tooltips now open ABOVE the button (no downward viewport clip);
keyboard use also reveals the auto-hidden controls (wake() on keydown); added a
Download button that downloads the ORIGINAL physical file (no re-encode/repackage,
Content-Disposition attachment via GET /stream/{rk}/file?download=1).
- Plex cards: hover affordance shows what a click does (Play / Resume / Open show)
+ a quick watched/unwatched toggle (stopPropagation, no playback) — mirrors the
YT-feed card quick-actions. New plex i18n keys en/hu/de.
- Verified in a real browser: card hover Play overlay + watched toggle (marks watched
without opening), player download button present, tooltip-above, keyboard reveals
controls, correct durations (Enola Holmes 3 = 1:48:04).
- NOTE: 'The Three Diablos' showing 13:05 was NOT a bug — it is a 13-min short (file
ffprobe = 785s); the 1h42m film is 'The Last Wish'.
- backend: GET /api/plex/item/{rk} detail (metadata, cast + intro/credit markers
from Plex, episode prev/next, per-user resume+status); POST /item/{rk}/progress
(resume checkpoint, near-end→watched) + /state (new|watched|hidden).
- frontend PlexPlayer.tsx (lazy, pulls hls.js): full-page player over the Plex
module. Direct files stream raw <video>; remux via hls.js on the seek-restart
session — custom controls map the ABSOLUTE timeline over the session offset, and a
seek beyond the loaded region restarts the session at the target. Play/pause/resume
/restart, ±10s seek, prev/next episode (Shift+←/→), volume, windowed/fullscreen,
full keyboard, Skip intro/Skip credits from markers (shaded on the seekbar),
auto-advance + watched-on-end, resume from saved position, 10s progress checkpoints.
- PlexBrowse: card/episode click opens the player as a history subview (browser Back
returns to the grid/show). api client (plexItem/plexSession/plexProgress/plexSetState)
+ types; plex.player.* i18n en/hu/de. hls.js@^1.6.16.
- Verified over HTTP: detail w/ markers+cast+episode-nav, progress persist. Video
playback itself is pending browser UAT. Subtitle/audio track SELECTION deferred.
Validated end-to-end on a real remux file (h264+ac3 mkv). The riskiest part of the
Plex epic — on-the-fly playback from the local file — now proven.
- app/plex/stream.py: seek-restart HLS session model (one ffmpeg per item, restarted
at a seek offset via -ss). Video stream-COPY (I/O-bound, CPU-light — fine on the
GPU-less prod host) + audio→aac only when not already aac. Maps first video+audio,
drops subtitles (no VTT rendition clutter). Session cap + idle reaper.
- routes: POST /stream/{rk}/session?start= (direct→raw url, remux→HLS session,
transcode→501 P3), GET /stream/{rk}/file (206 range, direct), /index.m3u8, /seg_n.ts.
- KEY FINDINGS (hard-won): (1) ffmpeg -hls_playlist_type VOD does NOT write the
playlist mid-run (only at finalize) → use EVENT (append-only, appears immediately),
which suits the seek-restart model; (2) naive per-segment copy + keyframe-indexed
extraction are both unreliable (non-uniform/imprecise segments) — ffmpeg's own HLS
muxer is the only correct segmenter; (3) dev slowness was the Windows /downloads
bind-mount write + SMB read → PLEX_HLS_DIR env points scratch at fast container-local
/var/tmp on dev (prod keeps download_root, fast local disk).
Per user feedback: promote Plex from a hidden feed-Source option to a first-class
left-nav module, with its own filter sidebar and the shared top search box.
- Plex is now a nav-rail module (page='plex', gated on me.plex_enabled) — its own
page → correct browser Back/Forward; removed the Feed Source-dropdown 'plex' hack.
- PlexSidebar.tsx: left filter column (library scope, watch-state for movies:
all/unwatched/in_progress/watched, sort) — per-account persisted (App state).
- Header search box now also serves the Plex page (integrated search); the live
YouTube-search escalation stays feed-only.
- PlexBrowse.tsx reworked: infinite scroll (IntersectionObserver, no 'Load more'),
content-visibility for smoother long-list scroll, show drill-down rides history
(useHistorySubview) so Back returns to the grid; dropped the stray 'YouTube feed'
button on the show page.
- backend /browse gains a per-user watch-state filter (show=, movies only).
- plex i18n (navLabel + filter.*) en/hu/de.
Note: episode-title 'Episode N' on some shows (e.g. Westworld) is Plex-side
(unmatched show) — we mirror what Plex has; Match/Refresh in Plex + re-sync fixes it.
- app/plex/sync.py: full reconcile of enabled movie/show sections into plex_*
(upsert by rating_key). Reuses Plex's own codec info to classify browser
playability (direct/remux/transcode) — no ffprobe. Movies + episodes become
playable leaves; shows/seasons mirrored for the drill-down.
- routes/plex.py: GET /libraries, /browse (FTS search + sort + paging, movie
leaves or show cards), /show/{rk} (seasons+episodes, per-user state), /image
(proxies Plex art, no duplication); admin POST /sync. All auth'd, demo-allowed.
- scheduler: plex_sync job (interval settings.plex_sync_interval_min).
- Verified against the real server: 2 libs, 3206 movies, 260 shows/961 seasons/
14768 episodes synced in 13s; FTS search + drill-down work. Playability:
~1% direct, 89% remux, 6% transcode (informs P2/P3).
