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

楼上用的哪里的国补啊，我看北京的用不了啊

@bli22ard 实现在这里，就是很简单的 Arc 和 clone
```rust
/// Owned read half of a [`TcpStream`], created by [`into_split`].
///
/// Reading from an `OwnedReadHalf` is usually done using the convenience methods found
/// on the [`AsyncReadExt`] trait.
///
/// [`TcpStream`]: TcpStream
/// [`into_split`]: TcpStream::into_split()
/// [`AsyncReadExt`]: trait@crate::io::AsyncReadExt
#[derive(Debug)]
pub struct OwnedReadHalf {
inner: Arc<TcpStream>,
}

/// Owned write half of a [`TcpStream`], created by [`into_split`].
///
/// Note that in the [`AsyncWrite`] implementation of this type, [`poll_shutdown`] will
/// shut down the TCP stream in the write direction. Dropping the write half
/// will also shut down the write half of the TCP stream.
///
/// Writing to an `OwnedWriteHalf` is usually done using the convenience methods found
/// on the [`AsyncWriteExt`] trait.
///
/// [`TcpStream`]: TcpStream
/// [`into_split`]: TcpStream::into_split()
/// [`AsyncWrite`]: trait@crate::io::AsyncWrite
/// [`poll_shutdown`]: fn@crate::io::AsyncWrite::poll_shutdown
/// [`AsyncWriteExt`]: trait@crate::io::AsyncWriteExt
#[derive(Debug)]
pub struct OwnedWriteHalf {
inner: Arc<TcpStream>,
shutdown_on_drop: bool,
}

pub(crate) fn split_owned(stream: TcpStream) -> (OwnedReadHalf, OwnedWriteHalf) {
let arc = Arc::new(stream);
let read = OwnedReadHalf {
inner: Arc::clone(&arc),
};
let write = OwnedWriteHalf {
inner: arc,
shutdown_on_drop: true,
};
(read, write)
}
```

使用 into_split 可以分离读写

可以参考这里

你点击控件成功之后，给 A 窗口发送最小化消息 SendMessage(HWND, SC_MINIMIZE)就可以了吧

@capric 6, 8, 10, A4 的相纸都支持，调整进纸仓的卡扣就行
