# scrcpy (v1.4)
|
||
|
||
This application provides display and control of Android devices connected on
|
||
USB (or [over TCP/IP][article-tcpip]). 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][enable-adb] on your device(s).
|
||
|
||
[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
|
||
|
||
|
||
## Get the app
|
||
|
||
|
||
### Linux
|
||
|
||
On Linux, you typically need to [build the app manually][BUILD]. Don't worry,
|
||
it's not that hard.
|
||
|
||
For Arch Linux, two [AUR] packages have been created by users:
|
||
|
||
- [`scrcpy`](https://aur.archlinux.org/packages/scrcpy/)
|
||
- [`scrcpy-prebuiltserver`](https://aur.archlinux.org/packages/scrcpy-prebuiltserver/)
|
||
|
||
[AUR]: https://wiki.archlinux.org/index.php/Arch_User_Repository
|
||
|
||
For Gentoo, an [Ebuild] is available: [`scrcpy/`][ebuild-link].
|
||
|
||
[Ebuild]: https://wiki.gentoo.org/wiki/Ebuild
|
||
[ebuild-link]: https://github.com/maggu2810/maggu2810-overlay/tree/master/app-mobilephone/scrcpy
|
||
|
||
|
||
### Windows
|
||
|
||
For Windows, for simplicity, prebuilt archives with all the dependencies
|
||
(including `adb`) are available:
|
||
|
||
- [`scrcpy-win32-v1.4.zip`][direct-win32]
|
||
_(SHA-256: 1f72fa520980727e8943b7214b64c66b00b9b5267f7cffefb64fa37c3ca803cf)_
|
||
- [`scrcpy-win64-v1.4.zip`][direct-win64]
|
||
_(SHA-256: 382f02bd8ed3db2cc7ab15aabdb83674744993b936d602b01e6959a150584a79)_
|
||
|
||
[direct-win32]: https://github.com/Genymobile/scrcpy/releases/download/v1.4/scrcpy-win32-v1.4.zip
|
||
[direct-win64]: https://github.com/Genymobile/scrcpy/releases/download/v1.4/scrcpy-win64-v1.4.zip
|
||
|
||
You can also [build the app manually][BUILD].
|
||
|
||
|
||
### Mac OS
|
||
|
||
The application is available in [Homebrew]. Just install it:
|
||
|
||
[Homebrew]: https://brew.sh/
|
||
|
||
```bash
|
||
brew install scrcpy
|
||
```
|
||
|
||
You need `adb`, accessible from your `PATH`. If you don't have it yet:
|
||
|
||
```bash
|
||
brew cask install android-platform-tools
|
||
```
|
||
|
||
You can also [build the app manually][BUILD].
|
||
|
||
|
||
## Run
|
||
|
||
Plug an Android device, and execute:
|
||
|
||
```bash
|
||
scrcpy
|
||
```
|
||
|
||
It accepts command-line arguments, listed by:
|
||
|
||
```bash
|
||
scrcpy --help
|
||
```
|
||
|
||
For example, to decrease video bitrate to 2Mbps (default is 8Mbps):
|
||
|
||
```bash
|
||
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):
|
||
|
||
```bash
|
||
scrcpy -m 1024
|
||
```
|
||
|
||
The device screen may be cropped to mirror only part of the screen:
|
||
|
||
```bash
|
||
scrcpy -c 1224:1440:0:0 # 1224x1440 at offset (0,0)
|
||
```
|
||
|
||
If several devices are listed in `adb devices`, you must specify the _serial_:
|
||
|
||
```bash
|
||
scrcpy -s 0123456789abcdef
|
||
```
|
||
|
||
To show physical touches while scrcpy is running:
|
||
|
||
```bash
|
||
scrcpy -t
|
||
```
|
||
|
||
The app may be started directly in fullscreen:
|
||
|
||
```
|
||
scrcpy -f
|
||
```
|
||
|
||

|
||
## Why _scrcpy_?
|
||
|
||
A colleague challenged me to find a name as unpronounceable as [gnirehtet].
|
||
|
||
[`strcpy`] copies a **str**ing; `scrcpy` copies a **scr**een.
