Architecture

Invidious chỉ trên NestJS (INVIDIOUS_BASE_URL) cho search/related/trending. Worker tải qua /latest_version của instance → FFmpeg H.264/AAC/faststart MP4 (+ HLS optional) → MinIO reels/external/{id}/. Mobile chỉ nhận URL WELIFE (status=READY).

Commands

# api/.env
REELS_EXTERNAL_VIDEO_ENABLED=true
INVIDIOUS_ENABLED=true
INVIDIOUS_BASE_URL=https://your-selfhosted-invidious
INVIDIOUS_INGEST_ENABLED=true

cd api && npx prisma migrate deploy && npx prisma generate
npm run start:dev   # worker ingest chạy in-process

Local verify (2026-08-22)

prisma generate PASS
prisma migrate deploy PASS (20260822140000_reels_external_ingest)
nest build PASS
GET /health { status: ok }
GET /social/reels/feed?limit=5 { items: [], nextCursor: null } (chưa có reel READY)
GET /social/reels/search?q=gym { queued: 0 } vì INVIDIOUS_ENABLED mặc định false

YouTube discovery vẫn cần OWNER set INVIDIOUS_BASE_URL (self-host).

Known limitations

Bucket private: playback = MP4 presign (HLS nhiều segment khó ký từng file).
Invidious down → feed WELIFE + READY local vẫn chạy.
YouTube ingest vẫn phụ thuộc ToS/copyright — chỉ self-host instance, không hard-code public.
Không recommendation cá nhân hóa (đúng AC).
