CLI tool to convert videos to DASH and HLS with hardware acceleration (NVENC / Intel QSV / AMD AMF / VAAPI), adaptive streaming, and automatic thumbnails/poster.
**Features:**
- ⚡ Hardware acceleration: NVENC / Intel QSV / AMD AMF / VAAPI (auto priority)
- ⚡ Hardware acceleration: auto-detect encoder/decoder (NVENC / Intel QSV / AMD AMF / VAAPI / CPU)
- 🎯 Formats: DASH and HLS (shared segments)
- 📊 Quality profiles: multiple bitrates/FPS (auto or custom)
- 🖼️ Preview: thumbnail sprite + VTT, poster from the first frame

## Defaults & Automation
- Segment duration: 2 seconds
- Hardware accel: auto-detect (GPU if available, else CPU)
- Hardware accel: auto-detect best encoder/decoder (GPU if available, else CPU)
- Profiles: auto-selected based on source resolution
- Bitrate: BPP-based dynamic calculation
- Thumbnails: auto sprite (160×90, 1s interval) + VTT
- Poster: first frame (0:00:00, configurable via `-p`)
- Parallel encoding: enabled
- AV1: enabled only if hardware AV1 encoder detected (in auto mode); otherwise остаётся H.264
**Requirements:** Node.js ≥18.0.0, FFmpeg, MP4Box (gpac), optional NVIDIA/Intel/AMD GPU for acceleration
