跨平台 scrcpy显示/控制安卓手机方案

• Genymotion、Parallels Desktop 等虚拟机软件 太专业, 需要配置太多软件, 适合开发者.
• 国内一批安卓游戏助手都可以一试, 这里我随便下载了一款网易MuMu对字体的显示不太好. 可以尝试一下 傲软投屏（ApowerMirror）
• Vysor Pro 收费较贵，免费版广告又多

scrcpy

这里推荐一款开源免费, 跨平台支持 Win、Mac、Linux，可通过 USB 数据线 (或WiFi) 连接电脑，将手机画面投屏到电脑显示，并可使用键盘鼠标远程控制你的手机

This application provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access. It works on GNU/Linux, Windows and macOS.

It focuses on:

• lightness (native, displays only the device screen)
• performance (30~60fps)
• quality (1920×1080 or above)
• low latency (35~70ms)
• low startup time (~1 second to display the first image)
• non-intrusiveness (nothing is left installed on the device)

Requirements

The Android device requires at least API 21 (Android 5.0).

Make sure you enabled adb debugging on your device(s).

On some devices, you also need to enable an additional option to control it using keyboard and mouse.

Get the app

Linux

On Linux, you typically need to [build the app manually][BUILD]. Don't worry, it's not that hard.

A Snap package is available: scrcpy.

For Arch Linux, an AUR package is available: scrcpy.

For Gentoo, an Ebuild is available: scrcpy/.

Windows

For Windows, for simplicity, prebuilt archives with all the dependencies (including adb) are available:

• scrcpy-win32-v1.11.zip
• scrcpy-win64-v1.11.zip

macOS

brew install scrcpy

You need adb, accessible from your PATH. If you don't have it yet:

brew cask install android-platform-tools

Run 运行

插入一个 Android 设备，然后执行: Plug an Android device, and execute:

scrcpy

获得帮助 It accepts command-line arguments, listed by:

scrcpy --help

Features

Capture configuration

Reduce size 限制画面分辨率

Sometimes, it is useful to mirror an Android device at a lower definition to increase performance.

To limit both the width and height to some value (e.g. 1024):

scrcpy --max-size 1024
scrcpy -m 1024  # short version

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.

Change bit-rate 修改视频码率

The default bit-rate is 8 Mbps. To change the video bitrate (e.g. to 2 Mbps):

scrcpy --bit-rate 2M
scrcpy -b 2M  # short version

Limit frame rate 限制帧率

On devices with Android >= 10, the capture frame rate can be limited:

scrcpy --max-fps 15

Crop 裁剪

The device screen may be cropped to mirror only part of the screen.

This is useful for example to mirror only one eye of the Oculus Go:

scrcpy --crop 1224:1440:0:0   # 1224x1440 at offset (0,0)

If --max-size is also specified, resizing is applied after cropping.

Recording

投屏并录屏： It is possible to record the screen while mirroring:

scrcpy --record file.mp4
scrcpy -r file.mkv

To disable mirroring while recording: 不投屏只录屏：

scrcpy --no-display --record file.mp4
scrcpy -Nr file.mkv
# interrupt recording with Ctrl+C
# Ctrl+C does not terminate properly on Windows, so disconnect the device

"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.

Connection 连接

Wireless 无线连接

Scrcpy uses adb to communicate with the device, and adb can connect to a device over TCP/IP:

1. 查询设备当前的 IP 地址 (设置 →关于手机→状态)
2. 启用 adb TCP/IP 连接，执行命令：adb tcpip 5555，其中 5555 为端口号
3. 拔掉你的数据线
4. 通过 WiFi 进行连接，执行命令：adb connect 设备IP地址:5555
5. 重新启动 scrcpy 即可

It may be useful to decrease the bit-rate and the definition:

scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800  # short version

Multi-devices 多设备支持

If several devices are listed in adb devices, you must specify the serial:

scrcpy --serial 0123456789abcdef
scrcpy -s 0123456789abcdef  # short version

You can start several instances of scrcpy for several devices.

SSH tunnel 隧道

To connect to a remote device, it is possible to connect a local adb client to a remote adb server (provided they use the same version of the adb protocol):

adb kill-server    # kill the local adb server on 5037
ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
# keep this open

From another terminal:

scrcpy

Like for wireless connections, it may be useful to reduce quality:

scrcpy -b2M -m800 --max-fps 15

Window configuration

Title

By default, the window title is the device model. It can be changed:

scrcpy --window-title 'My device'

Position and size

The initial window position and size may be specified:

scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600

Borderless

To disable window decorations:

scrcpy --window-borderless

Always on top

保持 scrcpy 窗口始终在顶部: To keep the scrcpy window always on top:

scrcpy --always-on-top

Fullscreen 全屏

The app may be started directly in fullscreen:

scrcpy --fullscreen
scrcpy -f  # short version

Fullscreen can then be toggled dynamically with Ctrl+f.

Other mirroring options

Read-only 只读

To disable controls (everything which can interact with the device: input keys, mouse events, drag&drop files):

scrcpy --no-control
scrcpy -n

Turn screen off 关闭手机屏幕

It is possible to turn the device screen off while mirroring on start with a command-line option:

scrcpy --turn-screen-off
scrcpy -S

Or by pressing Ctrl+o at any time.

To turn it back on, press POWER (or Ctrl+p).

Render expired frames

By default, to minimize latency, scrcpy always renders the last decoded frame available, and drops any previous one.

To force the rendering of all frames (at a cost of a possible increased latency), use:

scrcpy --render-expired-frames

Show touches

For presentations, it may be useful to show physical touches (on the physical device).

Android provides this feature in Developers options.

Scrcpy provides an option to enable this feature on start and disable on exit:

scrcpy --show-touches
scrcpy -t

Note that it only shows physical touches (with the finger on the device).

Input control 输入控制

Copy-paste

可以在计算机和设备之间双向同步剪贴板 It is possible to synchronize clipboards between the computer and the device, in both directions:

• Ctrl+c copies the device clipboard to the computer clipboard将设备剪贴板复制到计算机剪贴板;
• Ctrl+Shift+v copies the computer clipboard to the device clipboard将计算机剪贴板复制到设备剪贴板;
• Ctrl+v pastes the computer clipboard as a sequence of text events (but breaks non-ASCII characters)将计算机剪贴板粘贴为一系列文本事件(但

中断非 ascii 字符)。.

Text injection preference

There are two kinds of events generated when typing text:

• key events, signaling that a key is pressed or released;
• text events, signaling that a text has been entered.

By default, letters are injected using key events, so that the keyboard behaves as expected in games (typically for WASD keys).

But this may cause issues. If you encounter such a problem, you can avoid it by:

scrcpy --prefer-text

(but this will break keyboard behavior in games)

File drop 文件拖拽

Install APK 安装APK包

To install an APK, drag & drop an APK file (ending with .apk) to the scrcpy window.

There is no visual feedback, a log is printed to the console.

Push file to device

To push a file to /sdcard/ on the device, drag & drop a (non-APK) file to the scrcpy window.

There is no visual feedback, a log is printed to the console.

The target directory can be changed on start:

scrcpy --push-target /sdcard/foo/bar/

Audio forwarding

| 可借助 USBaudio 这个开源项目实现，但仅支持 Linux 系统 |

Audio is not forwarded by scrcpy. Use [USBaudio] (Linux-only). [USBaudio]: https://github.com/rom1v/usbaudio [issue #14]: https://github.com/Genymobile/scrcpy/issues/14

Shortcuts

¹Double-click on black borders to remove them. ²Right-click turns the screen on if it was off, presses BACK otherwise.

Custom paths

To use a specific adb binary, configure its path in the environment variable ADB:

ADB=/path/to/adb scrcpy

To override the path of the scrcpy-server file, configure its path in SCRCPY_SERVER_PATH.
