# Note: GPU acceleration dependencies are in requirements-gpu.txt
# Install them separately based on your hardware:
#   pip install -r requirements-gpu.txt
#
# For hardware-accelerated video encoding (optional):
#   - NVIDIA: Install ffmpeg with NVENC support (h264_nvenc)
#   - AMD: Install ffmpeg with AMF support (h264_amf)
#   - Intel: Install ffmpeg with QuickSync support (h264_qsv)
#   - Apple: VideoToolbox is usually included in macOS ffmpeg builds
#
# Note: GPU acceleration is automatically detected and used when available.
# The system gracefully falls back to CPU if GPU libraries are not installed.
