# ScrCpy
This project displays screens of Android devices plugged on USB in live.
## Run
### Runtime requirements
This projects requires _FFmpeg_, _LibSDL2_ and _LibSDL2-net_.
#### Linux
Install the packages from your package manager. For example, on Debian:
sudo apt install ffmpeg libsdl2-2.0.0 libsdl2-net-2.0.0
#### Windows
From [MSYS2]:
pacman -S mingw-w64-x86_64-SDL2
pacman -S mingw-w64-x86_64-SDL2_net
pacman -S mingw-w64-x86_64-ffmpeg
[MSYS2]: http://www.msys2.org/
#### MacOS
TODO
## Build
The project is divided into two parts:
- the server, running on the device (in `server/`);
- the client, running on the computer (in `app/`).
The server is a raw Java project requiring Android SDK. It not an Android
project: the target file is a `.jar`, and a `main()` method is executed with
_shell_ rights.
The client is a C project using [SDL] and [FFmpeg], built with [Meson]/[Ninja].
The root directory contains a `Makefile` to build both parts.
[sdl]: https://www.libsdl.org/
[ffmpeg]: https://www.ffmpeg.org/
[meson]: http://mesonbuild.com/
[ninja]: https://ninja-build.org/
### Build requirements
Install the [Android SDK], the JDK 8 (`openjdk-8-jdk`), and the packages
described below.
[Android SDK]: https://developer.android.com/studio/index.html
#### Linux
sudo apt install make gcc openjdk-8-jdk pkg-config meson zip \
libavcodec-dev libavformat-dev libavutil-dev \
libsdl2-dev libsdl2-net-dev
#### Windows
Install these packages:
pacman -S mingw-w64-x86_64-make
pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-pkg-config
pacman -S mingw-w64-x86_64-meson
pacman -S zip
Java 8 is not available in MSYS2, so install it manually and make it available
from the `PATH`:
export PATH="$JAVA_HOME/bin:$PATH"
### Build
2017-12-12 22:54:33 +08:00
Make sure your `ANDROID_HOME` variable is set to your Android SDK directory:
export ANDROID_HOME=~/android/sdk
From the project root directory, execute:
make build
2017-12-12 22:54:33 +08:00
To run the build:
make run
It is also pass arguments to `scrcpy` via `make`:
make run ARGS="-p 1234"
The purpose of this command is to execute `scrcpy` during the development.

### Test
To execute unit tests:
make test
The server-side tests require JUnit 4:
sudo apt install junit4
### Generate a release
From the project root directory, execute:
make release
This will generate the application in `dist/scrcpy/`.

## Run
Plug a device, and from `dist/scrcpy/`, execute:
2017-12-12 22:54:33 +08:00
./scrcpy
If several devices are listed in `adb devices`, you must specify the _serial_:
./scrcpy 0123456789abcdef
To change the default port (useful to launch several `scrcpy` simultaneously):
./scrcpy -p 1234
Other options are available, check `scrcpy --help`.
