Display and control your Android device

scrcpy (v1.11)

This application provides display and control of Android devices connected onUSB (or over TCP/IP). It does not require any root access.It works on GNU/Linux, Windows and macOS.

screenshot

It focuses on:

  • lightness (native, displays only the device screen)
  • performance (30~60fps)
  • quality (1920×1080 or above)
  • low latency (35~70ms)
  • low startup time (~1 second to display the first image)
  • non-intrusiveness (nothing is left installed on the device)

Requirements

The Android device 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 tocontrol it using keyboard and mouse.

Get the app

Linux

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

A [Snap] package is available: scrcpy.

For Arch Linux, an [AUR] package is available: scrcpy.

For Gentoo, an [Ebuild] is available: scrcpy/.

Windows

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

You can also build the app manually.

macOS

The application is available in [Homebrew]. Just install it:

bashbrew install scrcpy

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

bashbrew cask install android-platform-tools

You can also build the app manually.

Run

Plug an Android device, and execute:

bashscrcpy

It accepts command-line arguments, listed by:

bashscrcpy --help

Features

Capture configuration

Reduce size

Sometimes, it is useful to mirror an Android device at a lower definition toincrease performance.

To limit both the width and height to some value (e.g. 1024):

bashscrcpy --max-size 1024scrcpy -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.

Change bit-rate

The default bit-rate is 8 Mbps. To change the video bitrate (e.g. to 2 Mbps):

bashscrcpy --bit-rate 2Mscrcpy -b 2M # short version

Limit frame rate

On devices with Android >= 10, the capture frame rate can be limited:

bashscrcpy --max-fps 15

Crop

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

This is useful for example to mirror only one eye of the Oculus Go:

bashscrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)

If --max-size is also specified, resizing is applied after cropping.

Recording

It is possible to record the screen while mirroring:

bashscrcpy --record file.mp4scrcpy -r file.mkv

To disable mirroring while recording:

“`bashscrcpy –no-display –record file.mp4scrcpy -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 (forperformance reasons). Frames are timestamped on the device, so [packet delayvariation] does not impact the recorded file.

Connection

Wireless

Scrcpy uses adb to communicate with the device, and adb can [connect] to adevice over TCP/IP:

  1. Connect the device to the same Wi-Fi as your computer.
  2. Get your device IP address (in Settings → About phone → Status).
  3. Enable adb over TCP/IP on your device: adb tcpip 5555.
  4. Unplug your device.
  5. Connect to your device: adb connect DEVICE_IP:5555 (replace DEVICE_IP).
  6. Run scrcpy as usual.

It may be useful to decrease the bit-rate and the definition:

bashscrcpy --bit-rate 2M --max-size 800scrcpy -b2M -m800 # short version

Multi-devices

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

bashscrcpy --serial 0123456789abcdefscrcpy -s 0123456789abcdef # short version

You can start several instances of scrcpy for several devices.

SSH tunnel

To connect to a remote device, it is possible to connect a local adb client toa remote adb server (provided they use the same version of the adbprotocol):

“`bashadb kill-server # kill the local adb server on 5037ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 yourremotecomputer

keep this open

“`

From another terminal:

bashscrcpy

Like for wireless connections, it may be useful to reduce quality:

scrcpy -b2M -m800 --max-fps 15

Window configuration

Title

By default, the window title is the device model. It can be changed:

bashscrcpy --window-title 'My device'

Position and size

The initial window position and size may be specified:

bashscrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600

Borderless

To disable window decorations:

bashscrcpy --window-borderless

Always on top

To keep the scrcpy window always on top:

bashscrcpy --always-on-top

Fullscreen

The app may be started directly in fullscreen:

bashscrcpy --fullscreenscrcpy -f # short version

Fullscreen can then be toggled dynamically with Ctrl+f.

Other mirroring options

Read-only

To disable controls (everything which can interact with the device: input keys,mouse events, drag&drop files):

bashscrcpy --no-controlscrcpy -n

Turn screen off

It is possible to turn the device screen off while mirroring on start with acommand-line option:

bashscrcpy --turn-screen-offscrcpy -S

Or by pressing Ctrl+o at any time.

To turn it back on, press POWER (or Ctrl+p).

Render expired frames

By default, to minimize latency, scrcpy always renders the last decoded frameavailable, and drops any previous one.

To force the rendering of all frames (at a cost of a possible increasedlatency), use:

bashscrcpy --render-expired-frames

Show touches

For presentations, it may be useful to show physical touches (on the physicaldevice).

Android provides this feature in Developers options.

Scrcpy provides an option to enable this feature on start and disable on exit:

bashscrcpy --show-touchesscrcpy -t

Note that it only shows physical touches (with the finger on the device).

Input control

Copy-paste

It is possible to synchronize clipboards between the computer and the device, inboth directions:

  • Ctrl+c copies the device clipboard to the computer clipboard;
  • Ctrl+Shift+v copies the computer clipboard to the device clipboard;
  • Ctrl+v pastes the computer clipboard as a sequence of text events (butbreaks non-ASCII characters).

Text injection preference

There are two kinds of events generated when typing text: – key events, signaling that a key is pressed or released; – text events, signaling that a text has been entered.

By default, letters are injected using key events, so that the keyboard behavesas expected in games (typically for WASD keys).

But this may cause issues. If you encounter such a problem, youcan avoid it by:

bashscrcpy --prefer-text

(but this will break keyboard behavior in games)

File drop

Install APK

To install an APK, drag & drop an APK file (ending with .apk) to the scrcpywindow.

There is no visual feedback, a log is printed to the console.

Push file to device

To push a file to /sdcard/ on the device, drag & drop a (non-APK) file to thescrcpy window.

There is no visual feedback, a log is printed to the console.

The target directory can be changed on start:

bashscrcpy --push-target /sdcard/foo/bar/

Audio forwarding

Audio is not forwarded by scrcpy. Use [USBaudio] (Linux-only).

Also see [issue #14].

¹Double-click on black borders to remove them.

Custom paths

To use a specific adb binary, configure its path in the environment variableADB:

ADB=/path/to/adb scrcpy

To override the path of the scrcpy-server file, configure its path inSCRCPY_SERVER_PATH.

Why scrcpy?

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

[strcpy] copies a string; scrcpy copies a screen.
