Raw Blame History

scrcpy

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).

You need adb. It is available in the Android SDK platform tools, or packaged in your distribution (android-adb-tools).

On Windows, if you use the prebuilt application, it is already included. Otherwise, just download the platform-tools and extract the following files to a directory accessible from your PATH:

adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll

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

The client requires FFmpeg and LibSDL2. On Windows, they are included in the prebuilt application.

Build and install

System-specific steps

Linux

Install the required packages from your package manager.

Debian/Ubuntu

# runtime dependencies
sudo apt install ffmpeg libsdl2-2.0.0

# client build dependencies
sudo apt install make gcc pkg-config meson \
                 libavcodec-dev libavformat-dev libavutil-dev \
                 libsdl2-dev

# server build dependencies
sudo apt install openjdk-8-jdk

Fedora

# enable RPM fusion free
sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm

# client build dependencies
sudo dnf install SDL2-devel ffms2-devel meson gcc make

# server build dependencies
sudo dnf install java

Arch Linux

Two AUR packages have been created by users:

Windows

For Windows, for simplicity, a prebuilt archive with all the dependencies (including adb) is available:

scrcpy-windows-with-deps-v1.1.zip.
(SHA-256: 27eb36c15937601d1062c1dc0b45faae0e06fefea2019aadeb4fa7f76a07bb4c)

(It's just a portable version including dll copied from MSYS2.)

Instead, you may want to build it manually.

Cross-compile from Linux

This is the preferred method (and the way the release is built).

From Debian, install mingw:

sudo apt install mingw-w64 mingw-w64-tools

You also need the JDK to build the server:

sudo apt install openjdk-8-jdk

Then generate the releases:

make -f Makefile.CrossWindows

It will generate win32 and win64 releases into dist/.

In MSYS2

From Windows, you need MSYS2 to build the project. From an MSYS2 terminal, install the required packages:

# runtime dependencies
pacman -S mingw-w64-x86_64-SDL2 \
          mingw-w64-x86_64-ffmpeg

# client build dependencies
pacman -S mingw-w64-x86_64-make \
          mingw-w64-x86_64-gcc \
          mingw-w64-x86_64-pkg-config \
          mingw-w64-x86_64-meson

For a 32 bits version, replace x86_64 by i686:

# runtime dependencies
pacman -S mingw-w64-i686-SDL2 \
          mingw-w64-i686-ffmpeg

# client build dependencies
pacman -S mingw-w64-i686-make \
          mingw-w64-i686-gcc \
          mingw-w64-i686-pkg-config \
          mingw-w64-i686-meson

Java (>= 7) is not available in MSYS2, so if you plan to build the server, install it manually and make it available from the PATH:

export PATH="$JAVA_HOME/bin:$PATH"

Mac OS

The application is available in Homebrew. Just install it:

brew install scrcpy

Instead, you may want to build it manually. Install the packages:

# runtime dependencies
brew install sdl2 ffmpeg

# client build dependencies
brew install pkg-config meson

Additionally, if you want to build the server, install Java 8 from Caskroom, and make it avaliable from the PATH:

brew tap caskroom/versions
brew cask install java8
export JAVA_HOME="$(/usr/libexec/java_home --version 1.8)"
export PATH="$JAVA_HOME/bin:$PATH"

Docker

See pierlon/scrcpy-docker.

Common steps

Install the Android SDK (Android Studio), and set ANDROID_HOME to its directory. For example:

export ANDROID_HOME=~/android/sdk

Clone the project:

git clone https://github.com/Genymobile/scrcpy
cd scrcpy

Then, build:

meson x --buildtype release --strip -Db_lto=true
cd x
ninja

You can test it from here:

ninja run

Or you can install it on the system:

sudo ninja install    # without sudo on Windows

This installs two files:

/usr/local/bin/scrcpy
/usr/local/share/scrcpy/scrcpy-server.jar

Just remove them to "uninstall" the application.

Prebuilt server

Since the server binary, that will be pushed to the Android device, does not depend on your system and architecture, you may want to use the prebuilt binary instead:

scrcpy-server-v1.1.jar.
(SHA-256: 14826512bf38447ec94adf3b531676ce038d19e7e06757fb4e537882b17e77b3)

In that case, the build does not require Java or the Android SDK.

Download the prebuilt server somewhere, and specify its path during the Meson configuration:

meson x --buildtype release --strip -Db_lto=true \
    -Dprebuilt_server=/path/to/scrcpy-server.jar
cd x
ninja
sudo ninja install

Run

At runtime, adb must be accessible from your PATH.

If everything is ok, just 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

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

To run without installing:

./run x [options]

(where x is your build directory).

Why scrcpy?

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

strcpy copies a string; scrcpy copies a screen.
