scrcpy (v1.16)

Read in another language

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.

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 Debian (testing and sid for now) and Ubuntu (20.04):

apt install scrcpy

A [Snap] package is available: scrcpy.

For Fedora, a [COPR] package is available: scrcpy.

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

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

You could also build the app manually (don't worry, it's not thathard).

Windows

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

• scrcpy-win64-v1.16.zip
  (SHA-256: 3f30dc5db1a2f95c2b40a0f5de91ec1642d9f53799250a8c529bc882bc0918f0)

It is also available in [Chocolatey]:

bashchoco install scrcpychoco install adb # if you don't have it yet

And in [Scoop]:

bashscoop install scrcpyscoop install adb # if you don't have it yet

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

The capture frame rate can be limited:

bashscrcpy --max-fps 15

This is officially supported since Android 10, but may work on earlier versions.

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.

Lock video orientation

To lock the orientation of the mirroring:

bashscrcpy --lock-video-orientation 0 # natural orientationscrcpy --lock-video-orientation 1 # 90° counterclockwisescrcpy --lock-video-orientation 2 # 180°scrcpy --lock-video-orientation 3 # 90° clockwise

This affects recording orientation.

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

```

"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

If the device is connected over TCP/IP:

bashscrcpy --serial 192.168.0.1:5555scrcpy -s 192.168.0.1:5555 # short version

You can start several instances of scrcpy for several devices.

Autostart on device connection

You could use [AutoAdb]:

bashautoadb scrcpy -s '{}'

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

To avoid enabling remote port forwarding, you could force a forward connectioninstead (notice the -L instead of -R):

```bashadb kill-server # kill the local adb server on 5037ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 yourremotecomputer

keep this open

```

From another terminal:

bashscrcpy --force-adb-forward

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 MOD+f.

Rotation

The window may be rotated:

bashscrcpy --rotation 1

Possibles values are: - 0: no rotation - 1: 90 degrees counterclockwise - 2: 180 degrees - 3: 90 degrees clockwise

The rotation can also be changed dynamically with MOD+←(left) and MOD+→ (right).

Note that scrcpy manages 3 different rotations: - MOD+r requests the device to switch between portrait and landscape (the current running app may refuse, if it does support the requested orientation). - --lock-video-orientation changes the mirroring orientation (the orientation of the video sent from the device to the computer). This affects the recording. - --rotation (or MOD+←/MOD+→) rotates only the window content. This affects only the display, not the recording.

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

Display

If several displays are available, it is possible to select the display tomirror:

bashscrcpy --display 1

The list of display ids can be retrieved by:

adb shell dumpsys display # search "mDisplayId=" in the output

The secondary display may only be controlled if the device runs at least Android10 (otherwise it is mirrored in read-only).

Stay awake

To prevent the device to sleep after some delay when the device is plugged in:

bashscrcpy --stay-awakescrcpy -w

The initial state is restored when scrcpy is closed.

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 MOD+o at any time.

To turn it back on, press MOD+Shift+o.

On Android, the POWER button always turns the screen on. For convenience, ifPOWER is sent via scrcpy (via right-click or MOD+p), itwill force to turn the screen off after a small delay (on a best effort basis).The physical POWER button will still cause the screen to be turned on.

It can also be useful to prevent the device from sleeping:

bashscrcpy --turn-screen-off --stay-awakescrcpy -Sw

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 restore theinitial value on exit:

bashscrcpy --show-touchesscrcpy -t

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

Disable screensaver

By default, scrcpy does not prevent the screensaver to run on the computer.

To disable it:

bashscrcpy --disable-screensaver

Input control

Rotate device screen

Press MOD+r to switch between portrait and landscapemodes.

Note that it rotates only if the application in foreground supports therequested orientation.

Copy-paste

Any time the Android clipboard changes, it is automatically synchronized to thecomputer clipboard.

Any Ctrl shortcut is forwarded to the device. In particular: - Ctrl+c typically copies - Ctrl+x typically cuts - Ctrl+v typically pastes (after computer-to-device clipboard synchronization)

This typically works as you expect.

The actual behavior depends on the active application though. For example,Termux sends SIGINT on Ctrl+c instead, and K-9 Mailcomposes a new message.

To copy, cut and paste in such cases (but only supported on Android >= 7): - MOD+c injects COPY - MOD+x injects CUT - MOD+v injects PASTE (after computer-to-device clipboard synchronization)

In addition, MOD+Shift+v allows to inject thecomputer clipboard text as a sequence of key events. This is useful when thecomponent does not accept text pasting (for example in Termux), but it canbreak non-ASCII content.

WARNING: Pasting the computer clipboard to the device (either viaCtrl+v or MOD+v) copies the contentinto the device clipboard. As a consequence, any Android application could readits content. You should avoid to paste sensitive content (like passwords) thatway.

Pinch-to-zoom

To simulate "pinch-to-zoom": Ctrl+click-and-move.

More precisely, hold Ctrl while pressing the left-click button. Untilthe left-click button is released, all mouse movements scale and rotate thecontent (if supported by the app) relative to the center of the screen.

Concretely, scrcpy generates additional touch events from a "virtual finger" ata location inverted through the center of the screen.

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)

Key repeat

By default, holding a key down generates repeated key events. This can causeperformance problems in some games, where these events are useless anyway.

To avoid forwarding repeated key events:

bashscrcpy --no-key-repeat

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 [sndcpy].

Also see [issue #14].

Shortcuts

In the following list, MOD is the shortcut modifier. By default, it's(left) Alt or (left) Super.

It can be changed using --shortcut-mod. Possible keys are lctrl, rctrl,lalt, ralt, lsuper and rsuper. For example:

```bash

use RCtrl for shortcuts

scrcpy --shortcut-mod=rctrl

use either LCtrl+LAlt or LSuper for shortcuts

scrcpy --shortcut-mod=lctrl+lalt,lsuper```

[Super] is typically the Windows or Cmd key.

| Action | Shortcut | ------------------------------------------- |:----------------------------- | Switch fullscreen mode | MOD+f | Rotate display left | MOD+← (left) | Rotate display right | MOD+→ (right) | Resize window to 1:1 (pixel-perfect) | MOD+g | Resize window to remove black borders | MOD+w \| Double-click¹ | Click on HOME | MOD+h \| Middle-click | Click on BACK | MOD+b \| Right-click² | Click on APP_SWITCH | MOD+s | Click on MENU (unlock screen) | MOD+m | Click on VOLUME_UP | MOD+↑ (up) | Click on VOLUME_DOWN | MOD+↓ (down) | Click on POWER | MOD+p | Power on | Right-click² | Turn device screen off (keep mirroring) | MOD+o | Turn device screen on | MOD+Shift+o | Rotate device screen | MOD+r | Expand notification panel | MOD+n | Collapse notification panel | MOD+Shift+n | Copy to clipboard³ | MOD+c | Cut to clipboard³ | MOD+x | Synchronize clipboards and paste³ | MOD+v | Inject computer clipboard text | MOD+Shift+v | Enable/disable FPS counter (on stdout) | MOD+i | Pinch-to-zoom | Ctrl+click-and-move

¹Double-click on black borders to remove them.
²Right-click turns the screen on if it was off, presses BACK otherwise.
³Only on Android >= 7.

All Ctrl+key shortcuts are forwarded to the device, so they arehandled by the active application.

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.
