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.
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!
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.
