# scrcpy (v1.25) scrcpy _pronounced "**scr**een **c**o**py**"_ [Read in another language](#translations) This application provides display and control of Android devices connected via USB or [over TCP/IP](#tcpip-wireless). It does not require any _root_ access. It works on _GNU/Linux_, _Windows_ and _macOS_. ![screenshot](assets/screenshot-debian-600.jpg) It focuses on: - **lightness**: native, displays only the device screen - **performance**: 30~120fps, depending on the device - **quality**: 1920×1080 or above - **low latency**: [35~70ms][lowlatency] - **low startup time**: ~1 second to display the first image - **non-intrusiveness**: nothing is left installed on the Android device - **user benefits**: no account, no ads, no internet required - **freedom**: free and open source software [lowlatency]: https://github.com/Genymobile/scrcpy/pull/646 Its features include: - [recording](#recording) - mirroring with [Android device screen off](#turn-screen-off) - [copy-paste](#copy-paste) in both directions - [configurable quality](#capture-configuration) - Android device [as a webcam (V4L2)](#v4l2loopback) (Linux-only) - [physical keyboard simulation (HID)](#physical-keyboard-simulation-hid) - [physical mouse simulation (HID)](#physical-mouse-simulation-hid) - [OTG mode](#otg) - and more… ## Requirements The Android device requires at least API 21 (Android 5.0). Make sure you [enable adb debugging][enable-adb] on your device(s). [enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling On some devices, you also need to enable [an additional option][control] to control it using a keyboard and mouse. [control]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323 ## Get the app Packaging status ### Summary - Linux: `apt install scrcpy` - Windows: [download][direct-win64] - macOS: `brew install scrcpy` Build from sources: [BUILD] ([simplified process][BUILD_simple]) [BUILD]: BUILD.md [BUILD_simple]: BUILD.md#simple ### Linux On Debian and Ubuntu: ``` apt install scrcpy ``` On Arch Linux: ``` pacman -S scrcpy ``` A [Snap] package is available: [`scrcpy`][snap-link]. [snap-link]: https://snapstats.org/snaps/scrcpy [snap]: https://en.wikipedia.org/wiki/Snappy_(package_manager) For Fedora, a [COPR] package is available: [`scrcpy`][copr-link]. [COPR]: https://fedoraproject.org/wiki/Category:Copr [copr-link]: https://copr.fedorainfracloud.org/coprs/zeno/scrcpy/ 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 You can also [build the app manually][BUILD] ([simplified process][BUILD_simple]). ### Windows For Windows, a prebuilt archive with all the dependencies (including `adb`) is available: - [`scrcpy-win64-v1.25.zip`][direct-win64] SHA-256: `db65125e9c65acd00359efb7cea9c05f63cc7ccd5833000cd243cc92f5053028` [direct-win64]: https://github.com/Genymobile/scrcpy/releases/download/v1.25/scrcpy-win64-v1.25.zip It is also available in [Chocolatey]: [Chocolatey]: https://chocolatey.org/ ```bash choco install scrcpy choco install adb # if you don't have it yet ``` And in [Scoop]: ```bash scoop install scrcpy scoop install adb # if you don't have it yet ``` [Scoop]: https://scoop.sh You can also [build the app manually][BUILD]. ### macOS 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 install android-platform-tools ``` It's also available in [MacPorts], which sets up `adb` for you: ```bash sudo port install scrcpy ``` [MacPorts]: https://www.macports.org/ You can also [build the app manually][BUILD]. ## Run Plug an Android device into your computer, and execute: ```bash scrcpy ``` It accepts command-line arguments, listed by: ```bash scrcpy --help ``` ## Features ### Capture configuration #### Reduce size Sometimes, it is useful to mirror an Android device at a lower resolution to increase performance. To limit both the width and height to some value (e.g. 1024): ```bash scrcpy --max-size=1024 scrcpy -m 1024 # short version ``` The other dimension is computed so that the Android 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): ```bash scrcpy --bit-rate=2M scrcpy -b 2M # short version ``` #### Limit frame rate The capture frame rate can be limited: ```bash scrcpy --max-fps=15 ``` This is officially supported since Android 10, but may work on earlier versions. The actual capture framerate may be printed to the console: ``` scrcpy --print-fps ``` It may also be enabled or disabled at any time with MOD+i. #### 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: ```bash scrcpy --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: ```bash scrcpy --lock-video-orientation # initial (current) orientation scrcpy --lock-video-orientation=0 # natural orientation scrcpy --lock-video-orientation=1 # 90° counterclockwise scrcpy --lock-video-orientation=2 # 180° scrcpy --lock-video-orientation=3 # 90° clockwise ``` This affects recording orientation. The [window may also be rotated](#rotation) independently. #### Codec The video codec can be selected: ```bash scrcpy --codec=h264 # default ``` ##### Encoder Some devices have more than one encoder for a specific codec, and some of them may cause issues or crash. It is possible to select a different encoder: ```bash scrcpy --encoder=OMX.qcom.video.encoder.avc ``` To list the available encoders, you can pass an invalid encoder name; the error will give the available encoders: ```bash scrcpy --encoder=_ # for the default codec scrcpy --codec=h264 --encoder=_ # for a specific codec ``` ### Capture #### Recording It is possible to record the screen while mirroring: ```bash scrcpy --record=file.mp4 scrcpy -r file.mkv ``` To disable mirroring while recording: ```bash scrcpy --no-display --record=file.mp4 scrcpy -Nr file.mkv # interrupt recording with Ctrl+C ``` "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. [packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation #### v4l2loopback On Linux, it is possible to send the video stream to a v4l2 loopback device, so that the Android device can be opened like a webcam by any v4l2-capable tool. The module `v4l2loopback` must be installed: ```bash sudo apt install v4l2loopback-dkms ``` To create a v4l2 device: ```bash sudo modprobe v4l2loopback ``` This will create a new video device in `/dev/videoN`, where `N` is an integer (more [options](https://github.com/umlaeute/v4l2loopback#options) are available to create several devices or devices with specific IDs). To list the enabled devices: ```bash # requires v4l-utils package v4l2-ctl --list-devices # simple but might be sufficient ls /dev/video* ``` To start `scrcpy` using a v4l2 sink: ```bash scrcpy --v4l2-sink=/dev/videoN scrcpy --v4l2-sink=/dev/videoN --no-display # disable mirroring window scrcpy --v4l2-sink=/dev/videoN -N # short version ``` (replace `N` with the device ID, check with `ls /dev/video*`) Once enabled, you can open your video stream with a v4l2-capable tool: ```bash ffplay -i /dev/videoN vlc v4l2:///dev/videoN # VLC might add some buffering delay ``` For example, you could capture the video within [OBS]. [OBS]: https://obsproject.com/ #### Buffering It is possible to add buffering. This increases latency, but reduces jitter (see [#2464]). [#2464]: https://github.com/Genymobile/scrcpy/issues/2464 The option is available for display buffering: ```bash scrcpy --display-buffer=50 # add 50 ms buffering for display ``` and V4L2 sink: ```bash scrcpy --v4l2-buffer=500 # add 500 ms buffering for v4l2 sink ``` ### Connection #### TCP/IP (wireless) _Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a device over TCP/IP. The device must be connected on the same network as the computer. ##### Automatic An option `--tcpip` allows to configure the connection automatically. There are two variants. If the device (accessible at 192.168.1.1 in this example) already listens on a port (typically 5555) for incoming _adb_ connections, then run: ```bash scrcpy --tcpip=192.168.1.1 # default port is 5555 scrcpy --tcpip=192.168.1.1:5555 ``` If _adb_ TCP/IP mode is disabled on the device (or if you don't know the IP address), connect the device over USB, then run: ```bash scrcpy --tcpip # without arguments ``` It will automatically find the device IP address and adb port, enable TCP/IP mode if necessary, then connect to the device before starting. ##### Manual Alternatively, it is possible to enable the TCP/IP connection manually using `adb`: 1. Plug the device into a USB port on your computer. 2. Connect the device to the same Wi-Fi network as your computer. 3. Get your device IP address, in Settings → About phone → Status, or by executing this command: ```bash adb shell ip route | awk '{print $9}' ``` 4. Enable `adb` over TCP/IP on your device: `adb tcpip 5555`. 5. Unplug your device. 6. Connect to your device: `adb connect DEVICE_IP:5555` _(replace `DEVICE_IP` with the device IP address you found)_. 7. Run `scrcpy` as usual. Since Android 11, a [Wireless debugging option][adb-wireless] allows to bypass having to physically connect your device directly to your computer. [adb-wireless]: https://developer.android.com/studio/command-line/adb#connect-to-a-device-over-wi-fi-android-11+ If the connection randomly drops, run your `scrcpy` command to reconnect. If it says there are no devices/emulators found, try running `adb connect DEVICE_IP:5555` again, and then `scrcpy` as usual. If it still says there are none found, try running `adb disconnect`, and then run those two commands again. It may be useful to decrease the bit-rate and the resolution: ```bash scrcpy --bit-rate=2M --max-size=800 scrcpy -b2M -m800 # short version ``` [connect]: https://developer.android.com/studio/command-line/adb.html#wireless #### Multi-devices If several devices are listed in `adb devices`, you can specify the _serial_: ```bash scrcpy --serial=0123456789abcdef scrcpy -s 0123456789abcdef # short version ``` The serial may also be provided via the environment variable `ANDROID_SERIAL` (also used by `adb`). If the device is connected over TCP/IP: ```bash scrcpy --serial=192.168.0.1:5555 scrcpy -s 192.168.0.1:5555 # short version ``` If only one device is connected via either USB or TCP/IP, it is possible to select it automatically: ```bash # Select the only device connected via USB scrcpy -d # like adb -d scrcpy --select-usb # long version # Select the only device connected via TCP/IP scrcpy -e # like adb -e scrcpy --select-tcpip # long version ``` You can start several instances of _scrcpy_ for several devices. #### Autostart on device connection You could use [AutoAdb]: ```bash autoadb scrcpy -s '{}' ``` [AutoAdb]: https://github.com/rom1v/autoadb #### Tunnels To connect to a remote device, it is possible to connect a local `adb` client to a remote `adb` server (provided they use the same version of the _adb_ protocol). ##### Remote ADB server To connect to a remote _adb server_, make the server listen on all interfaces: ```bash adb kill-server adb -a nodaemon server start # keep this open ``` **Warning: all communications between clients and the _adb server_ are unencrypted.** Suppose that this server is accessible at 192.168.1.2. Then, from another terminal, run `scrcpy`: ```bash # in bash export ADB_SERVER_SOCKET=tcp:192.168.1.2:5037 scrcpy --tunnel-host=192.168.1.2 ``` ```cmd :: in cmd set ADB_SERVER_SOCKET=tcp:192.168.1.2:5037 scrcpy --tunnel-host=192.168.1.2 ``` ```powershell # in PowerShell $env:ADB_SERVER_SOCKET = 'tcp:192.168.1.2:5037' scrcpy --tunnel-host=192.168.1.2 ``` By default, `scrcpy` uses the local port used for `adb forward` tunnel establishment (typically `27183`, see `--port`). It is also possible to force a different tunnel port (it may be useful in more complex situations, when more redirections are involved): ``` scrcpy --tunnel-port=1234 ``` ##### SSH tunnel To communicate with a remote _adb server_ securely, it is preferable to use an SSH tunnel. First, make sure the _adb server_ is running on the remote computer: ```bash adb start-server ``` Then, establish an SSH tunnel: ```bash # local 5038 --> remote 5037 # local 27183 <-- remote 27183 ssh -CN -L5038:localhost:5037 -R27183:localhost:27183 your_remote_computer # keep this open ``` From another terminal, run `scrcpy`: ```bash # in bash export ADB_SERVER_SOCKET=tcp:localhost:5038 scrcpy ``` ```cmd :: in cmd set ADB_SERVER_SOCKET=tcp:localhost:5038 scrcpy ``` ```powershell # in PowerShell $env:ADB_SERVER_SOCKET = 'tcp:localhost:5038' scrcpy ``` To avoid enabling remote port forwarding, you could force a forward connection instead (notice the `-L` instead of `-R`): ```bash # local 5038 --> remote 5037 # local 27183 --> remote 27183 ssh -CN -L5038:localhost:5037 -L27183:localhost:27183 your_remote_computer # keep this open ``` From another terminal, run `scrcpy`: ```bash # in bash export ADB_SERVER_SOCKET=tcp:localhost:5038 scrcpy --force-adb-forward ``` ```cmd :: in cmd set ADB_SERVER_SOCKET=tcp:localhost:5038 scrcpy --force-adb-forward ``` ```powershell # in PowerShell $env:ADB_SERVER_SOCKET = 'tcp:localhost:5038' scrcpy --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: ```bash scrcpy --window-title='My device' ``` #### Position and size The initial window position and size may be specified: ```bash scrcpy --window-x=100 --window-y=100 --window-width=800 --window-height=600 ``` #### Borderless To disable window decorations: ```bash scrcpy --window-borderless ``` #### Always on top To keep the _scrcpy_ window always on top: ```bash scrcpy --always-on-top ``` #### Fullscreen The app may be started directly in fullscreen: ```bash scrcpy --fullscreen scrcpy -f # short version ``` Fullscreen can then be toggled dynamically with MOD+f. #### Rotation The window may be rotated: ```bash scrcpy --rotation=1 ``` Possible values: - `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 not support the requested orientation). - [`--lock-video-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): ```bash scrcpy --no-control scrcpy -n ``` #### Display If several displays are available, it is possible to select the display to mirror: ```bash scrcpy --display=1 ``` The list of display ids can be retrieved by: ```bash adb shell dumpsys display # search "mDisplayId=" in the output ``` The secondary display may only be controlled if the device runs at least Android 10 (otherwise it is mirrored as read-only). #### Stay awake To prevent the device from sleeping after a delay when the device is plugged in: ```bash scrcpy --stay-awake scrcpy -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 a command-line option: ```bash scrcpy --turn-screen-off scrcpy -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, if `POWER` is sent via _scrcpy_ (via right-click or MOD+p), it will 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: ```bash scrcpy --turn-screen-off --stay-awake scrcpy -Sw ``` #### Power off on close To turn the device screen off when closing _scrcpy_: ```bash scrcpy --power-off-on-close ``` #### Power on on start By default, on start, the device is powered on. To prevent this behavior: ```bash scrcpy --no-power-on ``` #### Show touches 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 restore the initial value on exit: ```bash scrcpy --show-touches scrcpy -t ``` Note that it only shows _physical_ touches (by a finger on the device). #### Disable screensaver By default, _scrcpy_ does not prevent the screensaver from running on the computer. To disable it: ```bash scrcpy --disable-screensaver ``` ### Input control #### Rotate device screen Press MOD+r to switch between portrait and landscape modes. Note that it rotates only if the application in foreground supports the requested orientation. #### Copy-paste Any time the Android clipboard changes, it is automatically synchronized to the computer 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 Mail_ composes 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 injects the computer clipboard text as a sequence of key events. This is useful when the component does not accept text pasting (for example in _Termux_), but it can break non-ASCII content. **WARNING:** Pasting the computer clipboard to the device (either via Ctrl+v or MOD+v) copies the content into the Android clipboard. As a consequence, any Android application could read its content. You should avoid pasting sensitive content (like passwords) that way. Some Android devices do not behave as expected when setting the device clipboard programmatically. An option `--legacy-paste` is provided to change the behavior of Ctrl+v and MOD+v so that they also inject the computer clipboard text as a sequence of key events (the same way as MOD+Shift+v). To disable automatic clipboard synchronization, use `--no-clipboard-autosync`. #### Pinch-to-zoom To simulate "pinch-to-zoom": Ctrl+_click-and-move_. More precisely, hold down Ctrl while pressing the left-click button. Until the left-click button is released, all mouse movements scale and rotate the content (if supported by the app) relative to the center of the screen. Technically, _scrcpy_ generates additional touch events from a "virtual finger" at a location inverted through the center of the screen. #### Physical keyboard simulation (HID) By default, _scrcpy_ uses Android key or text injection: it works everywhere, but is limited to ASCII. Alternatively, `scrcpy` can simulate a physical USB keyboard on Android to provide a better input experience (using [USB HID over AOAv2][hid-aoav2]): the virtual keyboard is disabled and it works for all characters and IME. [hid-aoav2]: https://source.android.com/devices/accessories/aoa2#hid-support However, it only works if the device is connected via USB. Note: On Windows, it may only work in [OTG mode](#otg), not while mirroring (it is not possible to open a USB device if it is already open by another process like the _adb daemon_). To enable this mode: ```bash scrcpy --hid-keyboard scrcpy -K # short version ``` If it fails for some reason (for example because the device is not connected via USB), it automatically fallbacks to the default mode (with a log in the console). This allows using the same command line options when connected over USB and TCP/IP. In this mode, raw key events (scancodes) are sent to the device, independently of the host key mapping. Therefore, if your keyboard layout does not match, it must be configured on the Android device, in Settings → System → Languages and input → [Physical keyboard]. This settings page can be started directly: ```bash adb shell am start -a android.settings.HARD_KEYBOARD_SETTINGS ``` However, the option is only available when the HID keyboard is enabled (or when a physical keyboard is connected). [Physical keyboard]: https://github.com/Genymobile/scrcpy/pull/2632#issuecomment-923756915 #### Physical mouse simulation (HID) Similarly to the physical keyboard simulation, it is possible to simulate a physical mouse. Likewise, it only works if the device is connected by USB. By default, _scrcpy_ uses Android mouse events injection with absolute coordinates. By simulating a physical mouse, a mouse pointer appears on the Android device, and relative mouse motion, clicks and scrolls are injected. To enable this mode: ```bash scrcpy --hid-mouse scrcpy -M # short version ``` You can also add `--forward-all-clicks` to [forward all mouse buttons][forward_all_clicks]. [forward_all_clicks]: #right-click-and-middle-click When this mode is enabled, the computer mouse is "captured" (the mouse pointer disappears from the computer and appears on the Android device instead). Special capture keys, either Alt or Super, toggle (disable or enable) the mouse capture. Use one of them to give the control of the mouse back to the computer. #### OTG It is possible to run _scrcpy_ with only physical keyboard and mouse simulation (HID), as if the computer keyboard and mouse were plugged directly to the device via an OTG cable. In this mode, `adb` (USB debugging) is not necessary, and mirroring is disabled. To enable OTG mode: ```bash scrcpy --otg # Pass the serial if several USB devices are available scrcpy --otg -s 0123456789abcdef ``` It is possible to enable only HID keyboard or HID mouse: ```bash scrcpy --otg --hid-keyboard # keyboard only scrcpy --otg --hid-mouse # mouse only scrcpy --otg --hid-keyboard --hid-mouse # keyboard and mouse # for convenience, enable both by default scrcpy --otg # keyboard and mouse ``` Like `--hid-keyboard` and `--hid-mouse`, it only works if the device is connected by USB. #### Text injection preference Two kinds of [events][textevents] are 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 behaves as expected in games (typically for WASD keys). But this may [cause issues][prefertext]. If you encounter such a problem, you can avoid it by: ```bash scrcpy --prefer-text ``` (but this will break keyboard behavior in games) On the contrary, you could force to always inject raw key events: ```bash scrcpy --raw-key-events ``` These options have no effect on HID keyboard (all key events are sent as scancodes in this mode). [textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input [prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343 #### Key repeat By default, holding a key down generates repeated key events. This can cause performance problems in some games, where these events are useless anyway. To avoid forwarding repeated key events: ```bash scrcpy --no-key-repeat ``` This option has no effect on HID keyboard (key repeat is handled by Android directly in this mode). #### Right-click and middle-click By default, right-click triggers BACK (or POWER on) and middle-click triggers HOME. To disable these shortcuts and forward the clicks to the device instead: ```bash scrcpy --forward-all-clicks ``` ### File drop #### Install APK 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. #### Push file to device To push a file to `/sdcard/Download/` 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. The target directory can be changed on start: ```bash scrcpy --push-target=/sdcard/Movies/ ``` ### Audio forwarding Audio is not forwarded by _scrcpy_. Use [sndcpy]. Also see [issue #14]. [sndcpy]: https://github.com/rom1v/sndcpy [issue #14]: https://github.com/Genymobile/scrcpy/issues/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._ [Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button) | 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-left-click¹_ | Click on `HOME` | MOD+h \| _Middle-click_ | Click on `BACK` | MOD+b \| _Right-click²_ | Click on `APP_SWITCH` | MOD+s \| _4th-click³_ | Click on `MENU` (unlock screen)⁴ | 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 \| _5th-click³_ | Expand settings panel | MOD+n+n \| _Double-5th-click³_ | Collapse panels | MOD+Shift+n | Copy to clipboard⁵ | MOD+c | Cut to clipboard⁵ | MOD+x | Synchronize clipboards and paste⁵ | MOD+v | Inject computer clipboard text | MOD+Shift+v | Enable/disable FPS counter (on stdout) | MOD+i | Pinch-to-zoom | Ctrl+_click-and-move_ | Drag & drop APK file | Install APK from computer | Drag & drop non-APK file | [Push file to device](#push-file-to-device) _¹Double-click on black borders to remove them._ _²Right-click turns the screen on if it was off, presses BACK otherwise._ _³4th and 5th mouse buttons, if your mouse has them._ _⁴For react-native apps in development, `MENU` triggers development menu._ _⁵Only on Android >= 7._ Shortcuts with repeated keys are executed by releasing and pressing the key a second time. For example, to execute "Expand settings panel": 1. Press and keep pressing MOD. 2. Then double-press n. 3. Finally, release MOD. All Ctrl+_key_ shortcuts are forwarded to the device, so they are handled by the active application. ## Custom paths To use a specific `adb` binary, configure its path in the environment variable `ADB`: ```bash ADB=/path/to/adb scrcpy ``` To override the path of the `scrcpy-server` file, configure its path in `SCRCPY_SERVER_PATH`. To override the icon, configure its path in `SCRCPY_ICON_PATH`. ## Why the name _scrcpy_? A colleague challenged me to find a name as unpronounceable as [gnirehtet]. [`strcpy`] copies a **str**ing; `scrcpy` copies a **scr**een. [gnirehtet]: https://github.com/Genymobile/gnirehtet [`strcpy`]: http://man7.org/linux/man-pages/man3/strcpy.3.html ## How to build?
