NAME
scrcpy - Display and control your Android device
SYNOPSIS
scrcpy [options]
DESCRIPTION
scrcpy provides display and control of Android devices connected on USB (or over TCP/IP). It does not
require any root access.
OPTIONS
--always-on-top
Make scrcpy window always on top (above other windows).
-b, --bit-rate value
Encode the video at the given bit-rate, expressed in bits/s. Unit suffixes are supported: 'K'
(x1000) and 'M' (x1000000).
Default is 8000000.
--codec-options key[:type]=value[,...]
Set a list of comma-separated key:type=value options for the device encoder.
The possible values for 'type' are 'int' (default), 'long', 'float' and 'string'.
The list of possible codec options is available in the Android documentation
https://d.android.com/reference/android/media/MediaFormat.
--crop width:height:x:y
Crop the device screen on the server.
The values are expressed in the device natural orientation (typically, portrait for a phone,
landscape for a tablet). Any --max-size value is computed on the cropped size.
--disable-screensaver
Disable screensaver while scrcpy is running.
--display id
Specify the display id to mirror.
The list of possible display ids can be listed by "adb shell dumpsys display" (search
"mDisplayId=" in the output).
Default is 0.
--display-buffer ms
Add a buffering delay (in milliseconds) before displaying. This increases latency to compensate
for jitter.
Default is 0 (no buffering).
--encoder name
Use a specific MediaCodec encoder (must be a H.264 encoder).
--force-adb-forward
Do not attempt to use "adb reverse" to connect to the device.
--forward-all-clicks
By default, right-click triggers BACK (or POWER on) and middle-click triggers HOME. This option
disables these shortcuts and forward the clicks to the device instead.
-f, --fullscreen
Start in fullscreen.
-h, --help
Print this help.
-K, --hid-keyboard
Simulate a physical keyboard by using HID over AOAv2.
This provides a better experience for IME users, and allows to generate non-ASCII characters,
contrary to the default injection method.
It may only work over USB, and is currently only supported on Linux.
The keyboard layout must be configured (once and for all) on the device, via Settings -> System ->
Languages and input -> Physical keyboard. This settings page can be started directly:
adb shell am start -a android.settings.HARD_KEYBOARD_SETTINGS
However, the option is only available when the HID keyboard is enabled (or a physical keyboard is
connected).
--legacy-paste
Inject computer clipboard text as a sequence of key events on Ctrl+v (like MOD+Shift+v).
This is a workaround for some devices not behaving as expected when setting the device clipboard
programmatically.
--lock-video-orientation[=value]
Lock video orientation to value. Possible values are "unlocked", "initial" (locked to the initial
orientation), 0, 1, 2 and 3. Natural device orientation is 0, and each increment adds a 90 degrees
rotation counterclockwise.
Default is "unlocked".
Passing the option without argument is equivalent to passing "initial".
--max-fps value
Limit the framerate of screen capture (officially supported since Android 10, but may work on
earlier versions).
-m, --max-size value
Limit both the width and height of the video to value. The other dimension is computed so that the
device aspect-ratio is preserved.
Default is 0 (unlimited).
--no-clipboard-autosync
By default, scrcpy automatically synchronizes the computer clipboard to the device clipboard
before injecting Ctrl+v, and the device clipboard to the computer clipboard whenever it changes.
This option disables this automatic synchronization.
-n, --no-control
Disable device control (mirror the device in read-only).
-N, --no-display
Do not display device (only when screen recording is enabled).
--no-key-repeat
Do not forward repeated key events when a key is held down.
--no-mipmaps
If the renderer is OpenGL 3.0+ or OpenGL ES 2.0+, then mipmaps are automatically generated to
improve downscaling quality. This option disables the generation of mipmaps.
-p, --port port[:port]
Set the TCP port (range) used by the client to listen.
Default is 27183:27199.
--power-off-on-close
Turn the device screen off when closing scrcpy.
--prefer-text
Inject alpha characters and space as text events instead of key events.
This avoids issues when combining multiple keys to enter special characters, but breaks the
expected behavior of alpha keys in games (typically WASD).
--push-target path
Set the target directory for pushing files to the device by drag & drop. It is passed as-is to
"adb push".
Default is "/sdcard/Download/".
--raw-key-events
Inject key events for all input keys, and ignore text events.
-r, --record file
Record screen to file.
The format is determined by the --record-format option if set, or by the file extension (.mp4 or
.mkv).
--record-format format
Force recording format (either mp4 or mkv).
--render-driver name
Request SDL to use the given render driver (this is just a hint).
Supported names are currently "direct3d", "opengl", "opengles2", "opengles", "metal" and
"software".
https://wiki.libsdl.org/SDL_HINT_RENDER_DRIVER
--rotation value
Set the initial display rotation. Possibles values are 0, 1, 2 and 3. Each increment adds a 90
degrees rotation counterclockwise.
-s, --serial number
The device serial number. Mandatory only if several devices are connected to adb.
--shortcut-mod key[+...]][,...]
Specify the modifiers to use for scrcpy shortcuts. Possible keys are "lctrl", "rctrl", "lalt",
"ralt", "lsuper" and "rsuper".
A shortcut can consist in several keys, separated by '+'. Several shortcuts can be specified,
separated by ','.
For example, to use either LCtrl+LAlt or LSuper for scrcpy shortcuts, pass "lctrl+lalt,lsuper".
Default is "lalt,lsuper" (left-Alt or left-Super).
--tcpip[=ip[:port]]
Configure and reconnect the device over TCP/IP.
If a destination address is provided, then scrcpy connects to this address before starting. The
device must listen on the given TCP port (default is 5555).
If no destination address is provided, then scrcpy attempts to find the IP address of the current
device (typically connected over USB), enables TCP/IP mode, then connects to this address before
starting.
-S, --turn-screen-off
Turn the device screen off immediately.
-t, --show-touches
Enable "show touches" on start, restore the initial value on exit.
It only shows physical touches (not clicks from scrcpy).
--tunnel-host ip
Set the IP address of the adb tunnel to reach the scrcpy server. This option automatically enables
--force-adb-forward.
Default is localhost.
--tunnel-port port
Set the TCP port of the adb tunnel to reach the scrcpy server. This option automatically enables
--force-adb-forward.
Default is 0 (not forced): the local port used for establishing the tunnel will be used.
--v4l2-sink /dev/videoN
Output to v4l2loopback device.
It requires to lock the video orientation (see --lock-video-orientation).
--v4l2-buffer ms
Add a buffering delay (in milliseconds) before pushing frames. This increases latency to
compensate for jitter.
This option is similar to --display-buffer, but specific to V4L2 sink.
Default is 0 (no buffering).
-V, --verbosity value
Set the log level ("verbose", "debug", "info", "warn" or "error").
Default is "info" for release builds, "debug" for debug builds.
-v, --version
Print the version of scrcpy.
-w, --stay-awake
Keep the device on while scrcpy is running, when the device is plugged in.
--window-borderless
Disable window decorations (display borderless window).
--window-title text
Set a custom window title.
--window-x value
Set the initial window horizontal position.
Default is "auto".
--window-y value
Set the initial window vertical position.
Default is "auto".
--window-width value
Set the initial window width.
Default is 0 (automatic).
--window-height value
Set the initial window height.
Default is 0 (automatic).
