feat(media): §3 audio STT + video 재생 인프라
plan: ~/.claude/plans/luminous-sprouting-hamster.md §3
스키마:
- migrations/147_audio_segments_table.sql: audio_segments (STT 타임스탬프
세그먼트)
- migrations/148_audio_segments_idx.sql: (document_id, start_s) idx
- migrations/149_document_media_cols.sql: documents.thumbnail_path +
needs_conversion
- migrations/150_queue_stage_stt.sql: process_stage += 'stt'
- migrations/151_queue_stage_thumbnail.sql: process_stage += 'thumbnail'
- app/models/audio_segment.py, document.py (thumbnail_path/needs_conversion)
서비스:
- services/stt/{Dockerfile, requirements.txt, server.py} — faster-whisper
large-v3 GPU 컨테이너. /transcribe (filePath/langs/beamSize) +
/health + /ready (cuda device_count + model_loaded). NFC/NFD 경로
resolver (OCR 교훈).
- docker-compose.yml: stt-service 추가 (GPU 1 예약, :3300, NAS ro mount,
stt_models volume, start_period 300s), fastapi env 에 STT_ENDPOINT.
파이프라인 (의존 §1 category):
- app/workers/stt_worker.py 신규: stage='stt' pickup → STT_ENDPOINT 호출 →
extracted_text + audio_segments 저장. Timeout 30분.
- app/workers/thumbnail_worker.py 신규: ffmpeg 50% 지점 1장 →
PKM/Videos/.thumbs/{id}.jpg + thumbnail_path 세팅.
needs_conversion=true 는 skip.
- app/workers/file_watcher.py 확장: PKM/{Inbox, Recordings, Videos}
스캔. 확장자→category, audio→stage=stt, video .mp4/.webm→
stage=thumbnail, video .mov/.mkv/.avi→needs_conversion=true + stage
없음. settings.roon_library_path prefix skip.
- app/workers/queue_consumer.py 확장: stt + thumbnail workers 등록,
BATCH_SIZE(stt=1, thumbnail=3), next_stages 에 stt→[classify] 추가
(audio 는 extract 건너뜀).
- app/Dockerfile: ffmpeg 추가 (썸네일 subprocess 용).
API (의존 §1):
- /api/audio/{id}/segments — AudioSegment ORDER BY start_s
- /api/video/{id}/thumbnail — thumbnail_path FileResponse (쿼리 토큰)
- /api/documents/{id}/file: media_types 에 audio/video mime 포함 (§2
커밋에 이미 포함). Starlette FileResponse 가 Range 자동.
- upload_document: .mov/.mkv/.avi 웹 업로드 거부 (error_code
unsupported_codec). NAS 드롭은 file_watcher 가 quarantine 수용.
프론트:
- AudioPlayer.svelte: HTML5 audio + 전사 세그먼트 sticky 패널 + 줄
클릭 seek. activeIdx 하이라이트.
- VideoPlayer.svelte: HTML5 video direct play + needs_conversion 안내
카드. poster 는 thumbnail endpoint.
- /audio (목록 grid) + /audio/[id] (플레이어)
- /video (썸네일 grid + 변환 필요 배지) + /video/[id] (플레이어)
- Sidebar.svelte: Mic/Film 아이콘 + audio/video 네비 활성, count
배지 (§2 /stats/category-counts 재사용).
설정:
- app/core/config.py: stt_endpoint + roon_library_path.
DoD 배포 후 smoke: /ready cuda:true, 회의 mp3 transcribe, audio
extract 없이 classify 진행(queue 회귀), /audio 재생, .mp4 재생,
.mov 웹 400, .mov NAS quarantine, Sidebar 네비 + count.
