fix(playback): transcode H.264 sources with conflicting in-band PPS
H.264 streams that redefine the same pic_parameter_set_id in-band with different content cannot be safely stream-copied into an avc1/fMP4 HLS segment: the avcC advertises a single parameter set, so VideoToolbox (Safari/Chrome on macOS) decodes with the wrong PPS and desyncs mid-GOP, surfacing as PIPELINE_ERROR_DECODE / kVTVideoDecoderBadDataErr (-12909). At playback start, a bitstream scan (DetectMultiplePPSH264) runs for H.264 files on the probe-ensure path, grouping in-band PPS by id and flagging any id carrying more than one distinct definition. The result is a runtime-only flag (VideoTrack.MultiplePPS, json:"-") memoized per process — never written to the database, no schema change, recomputed on the first play after a restart. The v3 planner and legacy resolver disqualify a copy-unsafe source from the video stream-copy / remux ladder, routing it to a real transcode. Direct play of the original container is left intact: decoders that reparse in-band parameter sets (ExoPlayer, VLC, native) handle the source fine. Part of #135. |

fix(playback): trust the server's media runtime end to end (#482)
* fix(scanner): reject durations that imply an impossible bitrate The duration-plausibility rule only rejected videos of 10 seconds or less, so a feature film that probed as 61 seconds passed untouched and persisted. Clients then had nothing trustworthy to anchor on: Android's grow-only duration ratchet has no floor to hold when the catalog value is wrong, so the playback engine's growing-HLS-window duration won and a 90-minute movie displayed as ~1 minute. Size and duration together pin an implied bitrate, which separates the two cases the absolute floor conflates. A genuine short clip has an ordinary bitrate; a 100 GB file claiming 61 seconds implies ~13 Gbps. The ceiling sits far above any real medium, so legitimate content cannot trip it — and unlike the absolute floor, it does not false-positive on a genuine high-bitrate short. Also bump the repair-rule revision marker so rows judged by the previous, weaker rule are re-checked once under this one. Without that bump an improved rule never reaches the rows it was written for. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(playback): publish source runtime in v3 plans and stop faking the copy seek window Two defects with one root: a v3 plan described where playback sits without ever stating how long the media is. Add source.duration_seconds. It is the file's full runtime, never `total - source_start` and never adjusted by timeline_offset_seconds, and it is omitted rather than null when unknown — clients that coerce null to a numeric default would read it as zero, the exact value this field exists to stop them inventing. It is set in SourceDescriptorFromFileV3, the single place every delivery already flows through, so direct play, progressive remux, HLS remux and HLS transcode all carry it. Until now the v3 plan omitted duration entirely, so clients fell back to the playback engine. On an HLS copy remux the server intentionally serves FFmpeg's still-growing playlist, so the engine reports the length produced so far. With no server-supplied runtime to anchor on, a feature film played back as a couple of minutes. The legacy protocol already answered this correctly via fileDurationSeconds; this restores parity. Separately, the copy branch published seek_window_end_seconds as the media runtime. That made the window look *complete*, which clients read as proof that any target inside it is locally seekable, so they native-seek past the produced head of a growing playlist instead of asking for a reanchor. Leave the end open: an incomplete window plus can_seek_anywhere=false routes every seek through the server, which is what legacy did before v3 added the bound. Advertise plan_source_duration_v1 so a client can distinguish "this server does not populate the field" from "this server knows the runtime is genuinely unknown" — without it, both look like an absent field and a client cannot tell whether its own catalog fallback is still required. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(web): pair the exit position with the media runtime, not the element duration The player's exit state converts its position to media time but took the duration from the video element, which is player-local. On a remux or transcode stream the element only covers the window produced so far, so the two values live in different coordinate systems. Resuming a movie 50 minutes in makes that concrete: the exit position is ~3060s of media time while the element reports ~120s. The progress cache then evaluates `position >= duration`, marks the item completed, latches the watched badge, and — because completion clears the resume point — resets position to 0. Exiting a resumed movie destroyed the resume point and claimed it had been watched. The server's runtime is authoritative and already expressed in media time, so prefer it and fall back to the element only when no server value exists. The rule moves into mediaTimeline.ts next to the coordinate conversions it depends on, which is also what makes it testable — VideoPlayer itself has no test harness.

feat(playback): formalize resumable direct streams and stall observability (#464)
* feat(playback): formalize resumable direct streams and stall observability Implements #443: strong stat-based ETag + If-Range on original-file direct play (via http.ServeContent), stream-end outcome classification in RollingDeadlineWriter (stalled_reap vs client_gone vs completed) with a structured log event and Prometheus counters, the direct_stream_resume_v1 protocol-v3 capability, and a contract doc. Progressive remux is explicitly excluded from the resume contract. Code written by OpenAI Codex CLI (gpt-5.6-sol) from a Claude-authored spec; reviewed and verified by Claude.

feat(playback): add protocol v3 planning and recovery (#398)
* docs(playback): plan protocol v3 server implementation * docs(playback): incorporate protocol v3 review * feat(playback): implement protocol v3 server * fix(playback): persist empty route diagnostics * feat(playback): harden protocol v3 HDR routing * feat(playback): complete protocol v3 client contract * fix(playback): harden protocol v3 recovery * fix(playback): restore dovi_rpu strip filter for DV remuxes The v3 work renamed the Dolby Vision strip recipe to a dovi_split=mode=bl bitstream filter that does not exist in stock FFmpeg or jellyfin-ffmpeg; the probe failed closed on every deployment, disabling the new validated DV7-to-HDR10 route and regressing the previously working dovi_rpu=strip=1 remux path from main. Restore dovi_rpu across the probe, remux and HLS copy arguments, and the recipe-card constant. Also from review: validate the remux DV mode for every profile (garbage modes on non-P7 sources silently no-opped), reject preserve mode for P7 outright (a base-layer-only remux cannot preserve dual-layer DV), tag dvhe sample entries only for the explicit v3 preserve recipe so legacy web/jellycompat remuxes keep their pre-v3 hev1 labeling, and honor the token-frozen DV mode in the proxy remux path instead of legacy-auto. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(playback): correct v3 planner policy and contract validation Review fixes to the v3 planner and wire contracts: - Bar Profile 7 sources from the non-strip progressive remux route: a base-layer-only remux can never deliver native dual-layer DV, so the planner no longer emits plans claiming validated Dolby Vision while the executed remux drops the enhancement layer. - Accept the device-quirks feature flag from either capability location, matching every other dual-location feature check. - Treat legacy hdr_unknown rows as HDR10 for HDR10-capable clients with a degradation warning instead of leaving them unplayable under v3. - Honor bandwidth_cap_kbps as a hard ceiling in every quality mode and wire the previously dead Metered signal into conservative auto rungs. - Degrade to the validated source-quality route instead of a terminal when only an implicit quality reduction demanded an unsupported transcode; explicit user-selected rungs keep terminal behavior. - Bound inner capability lists and strings; compare attempt keys exactly instead of case-folded; make ParseTrackIDV3 strict about canonical numerics; accept dvdsub/pgssub/dvbsub aliases and stop promising burn-in for unknown subtitle codecs; probe every h264 encoder rather than requiring libx264; normalize the file-level bitrate fallback. - Evaluate subtitle renderability against the engine each candidate route executes on, not always media3_direct. - Pin the with-quirks attempt-key preimage arity in the cross-language fixture so the Kotlin client stays in lockstep. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(playback): harden v3 control-plane reliability Review fixes to the v3 session, store, and handler layer: - Bound concurrent replans with a slot semaphore: each replan pins a pooled connection for its advisory lock while issuing further store queries from the same pool, so an unbounded recovery storm could turn every connection into a lock holder and deadlock the server. - Make CompleteReplan a real compare-and-swap (base-revision predicate, ErrReplanSupersededV3) and map BeginReplan insert races to a replay instead of a raw unique violation. - Fingerprint start requests (request_digest column): an attempt ID reused with different input is now a 409-style conflict rather than a silent replay, and both replay paths check session liveness so dead sessions surface as retryable terminals. - Pre-delete expired attempt rows on SaveAttempt so a retry during the cleanup window cannot wedge on an unreachable conflict. - Align the in-memory store's semantics with Postgres and add DB-backed planstore tests (SILO_TEST_DATABASE_URL), including a regression test inserting every route-event name against the real CHECK constraint. - Session manager: v3 route-set updates own RemuxDVMode outright so a replan onto an SDR source clears a stale strip mode; replacement reservations survive unrelated legacy stream updates; replacement admission excludes the replaced session explicitly instead of decrementing totals it may no longer be part of; the admission CAS loop is bounded and decider errors are logged. - Map transient store failures to 500s instead of terminal 404/403s; authorize route events via identity-only projections after the rate limiter; keep sanitized diagnostics deterministic. - Merge the server-computed durable plan key into replan exclusions so unreproducible client history cannot re-select the failed route. - Remap tracks only when the effective edition changes (a same-file replan no longer switches audio to a lookalike track) and remap ID-only subtitle selections on edition fallback. - Cache the v3/shadow feature flags for five seconds instead of one settings SELECT per playback request; stop remote transports best-effort when the start call times out; carry dvm/tid claims and the transport-scoped job identity through the legacy audio-change re-mint; index playback_route_events(received_at) for the retention delete; run store maintenance for DB-less deployments too. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(transcode): reap idle node jobs and gate WebVTT conversion - Add an idle reaper to the transcode node: a job untouched by manifest or segment requests for ten minutes is closed and unregistered. After a v3 replan retires a transport ID, a stale in-flight stream token could resurrect the old job via reconstruct and encode to end-of-file for nobody; jobs waiting on readiness count registration as access and are never reaped mid-wait, and reaping keeps the recipe so a still-valid token reconstructs on the next hit. - Reject bitmap subtitle tracks (PGS) on the .vtt conversion path with 415 before headers are written instead of spawning an ffmpeg command that always fails mid-response, and make the extract-format override fall back to source-driven mapping for bitmap codecs. - Drain error bodies on non-202 node responses so the HTTP transport can reuse connections. - Pin the transcode-dir cleanup separator-boundary semantics with a regression test (a session ID sharing another's prefix must not retain foreign directories). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(playback): close v3 planner policy gaps from review - Clamp the final transcode bitrate to bandwidth_cap_kbps: the ladder has no rung below 480p/1500kbps, so lower caps were silently exceeded even though the cap is documented as a hard delivery ceiling. - Treat video-only media as audio-compatible instead of forcing an AAC conversion (or an audio_conversion_unsupported terminal) onto a file with no audio stream. Tracks whose codec failed to probe keep the gate. - Only promise a bitmap subtitle sidecar for embedded PGS with an engine that renders embedded bitmap: external/downloaded bitmap and embedded DVD/DVB published artifact URLs that always failed at fetch. They now fall through to burn-in or its terminal. - Accept client_video_transformations_v1 from either client_features or the nested context when validating client-executor transformations, matching the planner's dual-source reads. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(playback): probe and execute DV remuxes with one ffmpeg binary The v3 transformation registry probed the configured playback.ffmpeg_path while progressive remux execution resolved the process-global discovery path, so a deployment where only one binary carries dovi_rpu could plan a server_dv7_to_hdr10 route and then fail it at stream time. Resolution now goes through a shared ResolveFFmpegPath (configured path first, discovery fallback — the same rule the transcode pipeline already used), the dovi_rpu probe is cached per binary path, and the stream handler and proxy worker pass their configured path into ServeRemuxWithDVMode. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(playback): harden v3 replan identity and control-plane limits - Seed failure-replan track selections from the durable current plan before overlaying the request: after an alternate-version fallback the normalized request still carries requested-edition track IDs, so a replan omitting unchanged tracks was rejected as a track/file mismatch. - Remap ID-only audio selections across edition changes (parse the ID to an index like the subtitle remap already does) instead of leaving a stale file-bound ID to fail validation. - Release the node planner reservation when a prepared remote transport rolls back after the node accepted the job; repeated failed starts could otherwise pin max-job/bandwidth budgets for the full reservation age. - Size the replan semaphore below the PostgreSQL pool via a store capacity advisor: with max_connections at or below the fixed bound, advisory-lock holders could starve the inner store queries they need to finish. - Contain shadow-planner panics with a recover boundary; it runs on a bare goroutine where an escaped panic kills the process for what is telemetry-only work. Document why the memory store's session lock is deliberately a no-op. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(transcode): serialize node job teardown against reconstructs - Look up and touch manifest/segment sessions in one critical section so the idle reaper cannot unregister a job between the lookup and its liveness refresh. - Re-validate each reap candidate under the per-session lifecycle lock before closing it: Close removes the output directory, and without the lock it could race a token reconstruct and wipe the segments the fresh ffmpeg is writing. - Take the lifecycle lock in handleStop so a stop racing a RequireReady start's readiness wait blocks until registration and tears the job down, instead of 404ing and orphaning the ffmpeg until the reaper.
