FU-06 (Audio Bridge STT orchestration): one download, two extractions — takes already-downloaded video bytes and extracts bounded mono 16kHz PCM WAV via the loopback broker's new mode=audio operation, sharing the exact same queue/deadline/byte budgets as the frame path. Dual opt-in (operator setting default false + per-request), only reaches the STT call when both are on.
Rebased onto the tip after sibling #12011 (subtitle mode) landed first, both touching the same broker route/client — combined additively so frames/audio/subtitles all share the one extractionQueue singleton. Re-validated: 59/59 focused tests pass.
FU-05 subtitle adapter (Refs #11659 — deliberately not Closes: the adapter is not yet wired into the live describeVideoPart path, that composition point is sibling #12009 which just landed): server-owned, loopback-only ffprobe/ffmpeg subtitle extraction that legitimately earns the "embedded" provenance label, mirroring the existing frame-extraction lifecycle. Broker route now also serves ?subtitles=1, stamped with the shared broker fingerprint so the client-side adapter can verify the payload actually came from the trusted process. Bounded, ReDoS-safe WebVTT parser.
Retargetado para release/v3.8.51 (release/v3.8.50 está congelada — freeze issue #11439). Validado em lote combinado (batch-0824h2, junto de #11435/#11436/#11437) contra o tip de release/v3.8.51: typecheck:core limpo, gates estáticos OK, 127/127 testes focados passando.
Investigação sólida com repro real via container isolado, três causas independentes identificadas e corrigidas com testes de regressão dedicados para cada uma. Obrigado pela contribuição!
The per-session drill-down cache now tracks decoded bytes per entry and
evicts least-recently-used entries until an aggregate maxTotalBytes
budget fits (route sets 256 MiB); an entry larger than the whole budget
is rejected. Prevents the previous worst case of 64 x 32 MiB (~2 GiB)
pinned in memory.
Implements the secure, opt-in Video Bridge for issue #9760, including bounded FFmpeg frame extraction, capability-aware routing, telemetry, settings UI, localization, documentation, and regression coverage.
