scrcpy (v1.3)

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.

Requirements

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

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

Get the app

Linux

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

For Arch Linux, two AUR packages have been created by users:

Windows

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

You can also build the app manually.

Mac OS

The application is available in Homebrew. Just install it:

brew install scrcpy

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

brew cask install android-platform-tools

You can also build the app manually.

Run

Plug an Android device, and execute:

scrcpy

It accepts command-line arguments, listed by:

scrcpy --help

For example, to decrease video bitrate to 2Mbps (default is 8Mbps):

scrcpy -b 2M

To limit the video dimensions (e.g. if the device is 2540×1440, but the host screen is smaller, or cannot decode such a high definition):

scrcpy -m 1024

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

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

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

scrcpy -s 0123456789abcdef

To show physical touches while scrcpy is running:

scrcpy -t

Why scrcpy?

A colleague challenged me to find a name as unpronounceable as gnirehtet.

strcpy copies a string; scrcpy copies a screen.
