scrcpy

這里推薦一款開源免費, 跨平臺支持 Win愉镰、Mac钧汹、Linux，可通過 USB 數(shù)據(jù)線 (或WiFi) 連接電腦碗降，將手機畫面投屏到電腦顯示塘秦，并可使用鍵盤鼠標遠程控制你的手機

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 運行

插入一個 Android 設備尊剔，然后執(zhí)行:
Plug an Android device, and execute:

scrcpy

獲得幫助
It accepts command-line arguments, listed by:

scrcpy --help

Features

Capture configuration

Reduce size 限制畫面分辨率

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 修改視頻碼率

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 限制幀率

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

投屏并錄屏：
It is possible to record the screen while mirroring:

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

To disable mirroring while recording: 不投屏只錄屏：

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 連接

Wireless 無線連接

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

1. 查詢設備當前的 IP 地址 (設置 →關于手機→狀態(tài))
2. 啟用 adb TCP/IP 連接挨稿，執(zhí)行命令：adb tcpip 5555，其中 5555 為端口號
3. 拔掉你的數(shù)據(jù)線
4. 通過 WiFi 進行連接奶甘，執(zhí)行命令：adb connect 設備IP地址:5555
5. 重新啟動 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 多設備支持

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 窗口始終在頂部:
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 只讀

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 關閉手機屏幕

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 輸入控制

Copy-paste

可以在計算機和設備之間雙向同步剪貼板
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將設備剪貼板復制到計算機剪貼板;
• Ctrl+Shift+v copies the computer clipboard to the device clipboard將計算機剪貼板復制到設備剪貼板;
• Ctrl+v pastes the computer clipboard as a sequence of text events (but breaks non-ASCII characters)將計算機剪貼板粘貼為一系列文本事件(但

中斷非 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 安裝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 這個開源項目實現(xiàn)侣监，但僅支持 Linux 系統(tǒng) |

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.
