The other dimension is computed to that the device aspect ratio is preserved. 较短的一边会被按比例缩小以保持设备的显示比例。
That way, a device in 1920×1080 will be mirrored at 1024×576. 这样，1920x1080的设备会以1020x576的分辨率显示。
#### 修改画面比特率 #### 修改画面比特率
The default bit-rate is 8 Mbps. To change the video bitrate (e.g. to 2 Mbps): 默认的比特率是8Mbps。如果要改变画面的比特率 (比如说改成2Mbps)：
```bash ```bash
scrcpy --bit-rate 2M scrcpy --bit-rate 2M
scrcpy -b 2M # short version scrcpy -b 2M # short version
``` ```
#### Limit frame rate #### 限制画面帧率
The capture frame rate can be limited: 画面的帧率可以通过下面的命令被限制：
```bash ```bash
scrcpy --max-fps 15 scrcpy --max-fps 15
``` ```
This is officially supported since Android 10, but may work on earlier versions. 这个功能仅在Android 10和以后的版本被Android官方支持，但也有可能在更早的版本可用。
#### Crop #### 画面裁剪
The device screen may be cropped to mirror only part of the screen. 设备画面可在输出到电脑时被裁切，以仅显示屏幕的一部分。
This is useful for example to mirror only one eye of the Oculus Go: 这项功能可以用于，例如，只显示Oculus Go的一只眼睛。
```bash ```bash
scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0) scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)
``` ```
If `--max-size` is also specified, resizing is applied after cropping. 如果`--max-size`在同时被指定，分辨率的改变将在画面裁切后进行。
#### Lock video orientation #### 锁定屏幕朝向
To lock the orientation of the mirroring: 可以使用如下命令锁定屏幕朝向：
```bash ```bash
scrcpy --lock-video-orientation 0 # natural orientation scrcpy --lock-video-orientation 0 # 自然朝向
scrcpy --lock-video-orientation 1 # 90° counterclockwise scrcpy --lock-video-orientation 1 # 90° 逆时针旋转
scrcpy --lock-video-orientation 2 # 180° scrcpy --lock-video-orientation 2 # 180°
scrcpy --lock-video-orientation 3 # 90° clockwise scrcpy --lock-video-orientation 3 # 90° 顺时针旋转
``` ```
This affects recording orientation. 该设定影响录制。
### Recording ### 屏幕录制
It is possible to record the screen while mirroring: 可以在传输的同时录制视频：
```bash ```bash
scrcpy --record file.mp4 scrcpy --record file.mp4
scrcpy -r file.mkv scrcpy -r file.mkv
``` ```
To disable mirroring while recording: 在不开启屏幕共享的同时录制：
```bash ```bash
scrcpy --no-display --record file.mp4 scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv scrcpy -Nr file.mkv
# interrupt recording with Ctrl+C # 按Ctrl+C以停止录制
``` ```
"Skipped frames" are recorded, even if they are not displayed in real time (for 在显示中“被跳过的帧”会被录制，虽然它们由于性能原因没有实时显示。

### Connection ### 连接方式
#### Wireless #### 无线
_Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a _Scrcpy_ 使用`adb`来与安卓设备连接。同时，`adb`能够通过TCP/IP[连接]到安卓设备:
device over TCP/IP:
1. Connect the device to the same Wi-Fi as your computer. 1. 将您的安卓设备和电脑连接至同一Wi-Fi。
2. Get your device IP address (in Settings → About phone → Status). 2. 获取安卓设备的IP地址（在设置-关于手机-状态信息）。
3. Enable adb over TCP/IP on your device: `adb tcpip 5555`. 3. 打开安卓设备的网络adb功能`adb tcpip 5555`。
4. Unplug your device. 4. 将您的设备与电脑断开连接。
5. Connect to your device: `adb connect DEVICE_IP:5555` _(replace `DEVICE_IP`)_. 5. 连接到您的设备：`adb connect DEVICE_IP:5555` _(用设备IP替换 `DEVICE_IP`)_.
6. Run `scrcpy` as usual. 6. 运行`scrcpy`。
It may be useful to decrease the bit-rate and the definition: 降低比特率和分辨率可能有助于性能：
```bash ```bash
scrcpy --bit-rate 2M --max-size 800 scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800 # short version scrcpy -b2M -m800 # short version
``` ```

#### Multi-devices #### 多设备
If several devices are listed in `adb devices`, you must specify the _serial_: 如果多个设备在执行`adb devices`后被列出，您必须指定设备的 _序列号_ ：
```bash ```bash
scrcpy --serial 0123456789abcdef scrcpy --serial 0123456789abcdef
scrcpy -s 0123456789abcdef # short version scrcpy -s 0123456789abcdef # short version
``` ```
If the device is connected over TCP/IP: 如果设备是通过TCP/IP方式连接到电脑的：
```bash ```bash
scrcpy --serial 192.168.0.1:5555 scrcpy --serial 192.168.0.1:5555
scrcpy -s 192.168.0.1:5555 # short version scrcpy -s 192.168.0.1:5555 # short version
``` ```
You can start several instances of _scrcpy_ for several devices. 您可以同时启动多个 _scrcpy_ 实例以同时显示多个设备的画面。

### Window configuration ### 窗口设置
#### Title #### 标题
By default, the window title is the device model. It can be changed: 窗口的标题默认为设备型号。您可以通过如下命令修改它：
```bash ```bash
scrcpy --window-title 'My device' scrcpy --window-title 'My device'
``` ```
#### Position and size #### 位置和大小
The initial window position and size may be specified: 您可以指定初始的窗口位置和大小：
```bash ```bash
scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600 scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600

#### Borderless #### 无边框
To disable window decorations: 关闭边框：
```bash ```bash
scrcpy --window-borderless scrcpy --window-borderless
``` ```
#### Always on top #### 保持窗口在最前
To keep the scrcpy window always on top: 您可以通过如下命令保持窗口在最前面：
```bash ```bash
scrcpy --always-on-top scrcpy --always-on-top
``` ```
#### Fullscreen #### 全屏
The app may be started directly in fullscreen: 您可以通过如下命令直接全屏打开共享：
```bash ```bash
scrcpy --fullscreen scrcpy --fullscreen
scrcpy -f # short version scrcpy -f # short version
``` ```
Fullscreen can then be toggled dynamically with <kbd>MOD</kbd>+<kbd>f</kbd>. 全屏状态可以通过<kbd>MOD</kbd>+<kbd>f</kbd>实时改变。
#### Rotation #### 旋转
The window may be rotated: 通过如下命令，窗口可以旋转：
```bash ```bash
scrcpy --rotation 1 scrcpy --rotation 1
``` ```
Possibles values are: 可选的值有：
- `0`: no rotation - `0`: 无旋转
- `1`: 90 degrees counterclockwise - `1`: 逆时针旋转90°
- `2`: 180 degrees - `2`: 旋转180°
- `3`: 90 degrees clockwise - `3`: 顺时针旋转90°
