Detailed Feature Descriptions 3.1 Playback Core | Sub‑Feature | Functional Requirements | Non‑Functional Requirements | |-------------|------------------------|-----------------------------| | HW‑accelerated decoding | Detect GPU capabilities on Windows, macOS, Linux, Android TV, iOS. Use FFmpeg + platform‑specific APIs (DXVA2, NVDEC, VA‑API, VideoToolbox). Auto‑fallback to software if unsupported. | Latency < 30 ms for frame decode; < 5 % CPU usage for 4K HDR on supported hardware. | | Frame‑accurate seeking | Seek using key‑frame index + nearest‑frame interpolation (if codec supports). UI: draggable timeline with frame preview thumbnails. | < 100 ms delay from user input to frame display. | | 360°/VR playback | Detect headset (Oculus Quest, HTC Vive, Cardboard) via WebXR or native SDK. Provide yaw/pitch controls. | Maintain 90 fps on 4K equirectangular video with low motion sickness. | | Audio track & subtitle switching | Hot‑swap without stopping playback. Remember last used language per user profile. | Zero audible glitch (< 10 ms gap). | | Speed control + pitch correction | Use WSOLA or Rubber Band library for tempo change without pitch distortion. | Audio sync error < 20 ms across speed range. | 3.2 Library Management | Sub‑Feature | Functional Requirements | Non‑Functional Requirements | |-------------|------------------------|-----------------------------| | Automatic metadata fetch | When a new MKV is added, compute a fuzzy title hash → query TMDB/OMDB APIs. Cache results locally (SQLite). Allow manual override. | 95 % match accuracy on 10 k‑movie test set. API‑rate‑limit handling with exponential back‑off. | | Bulk import & watch folder | User selects a root folder; daemon watches for file creation/deletion. Supports network shares (SMB, NFS). | Indexing speed ≥ 2 GB/min on SSD. | | Smart collections | UI for creating dynamic filters (e.g., “All 4K HDR movies released after 2015”). | Real‑time update when underlying items change. | | Duplicate detection | Compute SHA‑256 hash of first/last 10 MB + duration; present UI for merge/keep/both. | No false‑positive duplicate > 0.5 % on a 50 k‑movie dataset. | 3.3 UI / UX | Sub‑Feature | Functional Requirements | Non‑Functional Requirements | |-------------|------------------------|-----------------------------| | Cinema‑mode UI | Full‑screen overlay with auto‑hide after 3 s.
