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.
The Android part 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.
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:
For Gentoo, an Ebuild is available: scrcpy/
.
For Windows, for simplicity, prebuilt archives with all the dependencies
(including adb
) are available:
scrcpy-win32-v1.8.zip
(SHA-256: c0c29ed1c66deaa73bdadacd09e598aafb3a117929cf7a314cce1cc45e34de53)scrcpy-win64-v1.8.zip
(SHA-256: 9cc980d07bd8f036ae4e91d0bc6fc3281d7fa8f9752d4913b643c0fb72a19fb7)
You can also build the app manually.
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.
Plug an Android device, and execute:
scrcpy
It accepts command-line arguments, listed by:
scrcpy --help
Sometimes, it is useful to mirror an Android device at a lower definition to increase performances.
To limit both 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.
The default bit-rate is 8Mbps. To change the video bitrate (e.g. to 2Mbps):
scrcpy --bit-rate 2M
scrcpy -b 2M # short version
The device screen may be cropped to mirror only part of the screen.
This is useful for example to mirror only 1 eye of the Oculus Go:
scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)
scrcpy -c 1224:1440:0:0 # short version
If --max-size
is also specified, resizing is applied after cropping.
Scrcpy uses adb
to communicate with the device, and adb
can connect to a
device over TCP/IP:
- Connect the device to the same Wi-Fi as your computer.
- Get your device IP address (in Settings → About phone → Status).
- Enable adb over TCP/IP on your device:
adb tcpip 5555
. - Unplug your device.
- Connect to your device:
adb connect DEVICE_IP:5555
(replaceDEVICE_IP
). - Run
scrcpy
as usual.
It may be useful to decrease the bit-rate and the definition:
scrcpy --bit-rate 2M --max-size 800
scrcpy -b2M -m800 # short version
It is possible to record the screen while mirroring:
scrcpy --record file.mp4
scrcpy -r file.mkv
To disable mirroring while recording:
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.
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.
The app may be started directly in fullscreen:
scrcpy --fullscreen
scrcpy -f # short version
Fullscreen can then be toggled dynamically with Ctrl
+f
.
The window of app can always be above others by:
scrcpy --always-on-top
scrcpy -T # short version
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).
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.
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.
To disable controls (everything which can interact with the device: input keys, mouse events, drag&drop files):
scrcpy --no-control
scrcpy -n
Audio is not forwarded by scrcpy.
There is a limited solution using AOA, implemented in the audio
branch. If
you are interested, see issue 14.
