The other dimension is computed to that the device aspect ratio is preserved.
That way, a device in 1920×1080 will be mirrored at 1024×576.
较短的一边会被按比例缩小以保持设备的显示比例。
这样1920x1080的设备会以1020x576的分辨率显示。
#### 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
scrcpy --bit-rate 2M
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
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
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
scrcpy --lock-video-orientation 0 # natural orientation
scrcpy --lock-video-orientation 1 # 90° counterclockwise
scrcpy --lock-video-orientation 0 # 自然朝向
scrcpy --lock-video-orientation 1 # 90° 逆时针旋转
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
scrcpy --record file.mp4
scrcpy -r file.mkv
```
To disable mirroring while recording:
在不开启屏幕共享的同时录制:
```bash
scrcpy --no-display --record file.mp4
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
performance reasons). Frames are _timestamped_ on the device, so [packet delay
variation] does not impact the recorded file.
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。
在传输中每一帧都有 _时间戳_ ,所以 [包时延变化] 并不影响录制的文件。

### Connection
### 连接方式
#### Wireless
#### 无线
_Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a
device over TCP/IP:
_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:
1. Connect the device to the same Wi-Fi as your computer.
2. Get your device IP address (in Settings → About phone → Status).
3. Enable adb over TCP/IP on your device: `adb tcpip 5555`.
4. Unplug your device.
5. Connect to your device: `adb connect DEVICE_IP:5555` _(replace `DEVICE_IP`)_.
6. Run `scrcpy` as usual.
1. 将您的安卓设备和电脑连接至同一Wi-Fi。
2. 获取安卓设备的IP地址在设置-关于手机-状态信息)。
3. 打开安卓设备的网络adb功能`adb tcpip 5555`
4. 将您的设备与电脑断开连接。
5. 连接到您的设备:`adb connect DEVICE_IP:5555` _(用设备IP替换 `DEVICE_IP`)_.
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
scrcpy --bit-rate 2M --max-size 800
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
scrcpy --serial 0123456789abcdef
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
scrcpy --serial 192.168.0.1:5555
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
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
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
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
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
scrcpy --fullscreen
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
scrcpy --rotation 1
```
Possibles values are:
- `0`: no rotation
- `1`: 90 degrees counterclockwise
- `2`: 180 degrees
- `3`: 90 degrees clockwise
可选的值有:
- `0`: 无旋转
- `1`: 逆时针旋转90°
- `2`: 旋转180°
- `3`: 顺时针旋转90°
The rotation can also be changed dynamically with <kbd>MOD</kbd>+<kbd></kbd>
_(left)_ and <kbd>MOD</kbd>+<kbd></kbd> _(right)_.
这同样可以使用<kbd>MOD</kbd>+<kbd></kbd>
_(left)_ and <kbd>MOD</kbd>+<kbd></kbd> _(right)_ 的快捷键实时更改。

## Custom paths
## 自定义路径
To use a specific _adb_ binary, configure its path in the environment variable
`ADB`:
为了使用您想使用的 _adb_ ,您可以在环境变量
`ADB`中设置它的路径:
ADB=/path/to/adb scrcpy
To override the path of the `scrcpy-server` file, configure its path in
`SCRCPY_SERVER_PATH`.
如果需要覆盖`scrcpy-server`的路径,您可以在
`SCRCPY_SERVER_PATH`中设置它。

## 为什么叫 _scrcpy_
A colleague challenged me to find a name as unpronounceable as [gnirehtet].
一个同事让我找出一个和[gnirehtet]一样难以发音的名字。
