摘要： 將本機開發的 360° 全景影片播放器納入版控，同時把執行環境從 Windows 切換到 Synology NAS，改以 Docker 部署。 根本原因： 專案原本只在有 NVIDIA 顯卡的 Windows 機器上跑，config.json 寫死了 Windows 磁碟機路徑 W:/photo/Badminton，NAS 上無法直接啟動。 另外 DSM 內建的 ffmpeg 拿掉了 VAAPI 編碼器，裸跑只能走 libx264， Celeron J4025 雙核轉 4K 360 影片的速度無法接受。 影響： - 在 NAS 上 npm start 會因為找不到影片資料夾而列不出任何影片 - 即使把路徑改對，轉檔仍只能用 CPU，82 分鐘的 4K 360 影片要跑十幾小時 修法： - config.json 的 videoDir 改為 NAS 實際路徑 /volume1/photo/Badminton - docker-compose.yml 啟用 devices: /dev/dri，讓容器取得 Intel UHD 600 的 render node；容器內 Alpine 版 ffmpeg 保有完整 VAAPI 支援，啟動時 會自動偵測成 vaapi 模式，並保留 libx264 當備援 - .env（不進版控）提供 VIDEO_DIR / CACHE_DIR 等 NAS 路徑給 compose 使用 驗證： 容器啟動 log 顯示「轉檔引擎：VAAPI 硬體編碼（Intel/AMD，/dev/dri）」， /api/config 回傳 modes: ["vaapi","cpu"]，/api/videos 正確辨識來源影片為 3840x1920 equirectangular。 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
