Adrien Toupet daa13fb4ca Fix BlockSwap logging confusion and CLI worker validation
- BlockSwap: Show effective/total blocks (e.g., 32/32) instead of raw requested value
- CLI: Skip CUDA device validation when CUDA_VISIBLE_DEVICES already set (worker process)

SeedVR2 Video Upscaler - Standalone CLI Interface
Command-line interface for high-quality upscaling using SeedVR2 diffusion models.
Supports single and multi-GPU processing with advanced memory optimization.
Key Features:
• Multi-GPU Processing: Automatic workload distribution across multiple GPUs with
temporal overlap blending for seamless transitions
• Memory Optimization: BlockSwap for limited VRAM, VAE tiling for large resolutions,
intelligent tensor offloading between processing phases
• Performance: Torch.compile integration, BFloat16 compute pipeline,
efficient model caching for batch processing
• Flexibility: Multiple output formats (MP4/PNG), advanced color correction methods,
directory batch processing with auto-format detection
• Quality Control: Temporal overlap blending, frame prepending for artifact reduction,
configurable noise scales for detail preservation
Architecture:
The CLI implements a 4-phase processing pipeline:
1. Encode: VAE encoding with optional input noise and tiling
2. Upscale: DiT transformer upscaling with latent space diffusion
3. Decode: VAE decoding with optional tiling
4. Postprocess: Color correction and temporal blending
Usage:
python inference_cli.py video.mp4 --resolution 1080
For complete usage examples, run: python inference_cli.py --help
Requirements:
• Python 3.10+
• PyTorch 2.4+ with CUDA 12.1+ (NVIDIA) or MPS (Apple Silicon)
• 16GB+ VRAM recommended (8GB minimum with BlockSwap)
• OpenCV, NumPy for video I/O
Model Support:
• 3B models: seedvr2_ema_3b_fp16.safetensors (default), _fp8_e4m3fn/GGUF variants
• 7B models: seedvr2_ema_7b_fp16.safetensors, _fp8_e4m3fn/GGUF variants
• VAE: ema_vae_fp16.safetensors (shared across all models)
• Auto-downloads from HuggingFace on first run with SHA256 validation
