# NodeCast TV Docker Image
#
# Multi-stage build for FFmpeg with full hardware acceleration support.
# Uses linuxserver/ffmpeg which includes NVENC, VAAPI, and QSV.
#
# 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 ...

# Stage 1: Get FFmpeg with all hardware encoders from linuxserver
FROM linuxserver/ffmpeg:latest AS ffmpeg

# Stage 2: Node.js runtime with app
FROM node:20-slim
