#!/usr/bin/env bash
# Helper to run the RetroHost container on Docker Desktop (Windows + WSL2).
#
# The image is GPU-agnostic: the video encoder is auto-detected at startup
# (nvenc > qsv > vaapi > libx264). GPU flags below are OPTIONAL — without
# any GPU flag the encoder falls back to libx264 (CPU) and the container
# starts normally on any machine.
#
# Prerequisites: Docker Desktop installed. Image built: docker build -t retrohost .
#
# Usage:
#   RETROHOST_WEBRTC_HOST=192.168.1.100 ./docker-run-windows.sh
#   RETROHOST_WEBRTC_HOST=192.168.1.100 RETROHOST_GPU=nvidia ./docker-run-windows.sh
#
# Environment variables:
#   RETROHOST_WEBRTC_HOST  LAN IP of this machine (required for multi-device WebRTC)
#   RETROHOST_GPU          nvidia | dri | none  (default: none)
#   RETROHOST_ENCODER      Force a specific encoder, e.g. libx264 (overrides auto-detect)
