我跑 visual studio 2022 和 rust 自动化 runner ，用来编译代码，tiny10/tiny11 没有问题，是在 linux 下 qemu 跑的，不是物理机 https://github.com/dockur/windows

建议用 https://github.com/rust-cross/cargo-zigbuild 或者 https://github.com/cross-rs/cross 静态链接 musl ，不要静态链接 glibc ，可以动态链接 2012 年的 glibc2.17 ，就可以在主流相同指令集的 linux 上跑起来，比如 cargo zigbuild --target aarch64-unknown-linux-gnu.2.17

不是 DLNA ，AirPlay 镜像是屏幕声音录制，编码，加密，传输，显示端接收、解密，解码渲染，加密和编码有硬件加速，具体耗电量还得结合码率、画质看

@bli22ard 实现在这里，就是很简单的 Arc 和 clone
