# NodeCast TV Docker Image
#
# Uses system FFmpeg with hardware acceleration drivers installed.
#
# Hardware acceleration:
#   - VAAPI (Intel/AMD): Mount /dev/dri and add video/render groups
#   - NVIDIA NVENC: Requires nvidia-container-toolkit on host + --gpus flag
#   - Intel QSV: Mount /dev/dri
#
# Build: docker compose build
# Run with VAAPI: docker run --device /dev/dri:/dev/dri --group-add video ...
# Run with NVENC: docker run --gpus all ...
