# =====================================================================
# rtsp2other 镜像: 多阶段构建
# 镜像内的 ffmpeg / ffprobe / mediamtx 直接使用仓库内置的静态二进制
# (bin/linux-<arch>/, 由 TARGETARCH 自动选择, 与镜像目标架构一致),
# 构建过程不再从外部下载 ffmpeg, 保证镜像内容与仓库版本完全一致。
# 构建: docker build -t rtsp2other .
# 运行: docker run --rm -v $PWD/rtsp2other.yaml:/app/rtsp2other.yaml:ro \
#                  -p 8080:8080 -p 8554:8554 rtsp2other
# 多架构: docker buildx build --platform linux/amd64,linux/arm64 -t rtsp2other .
