NAME

SYNOPSIS

DESCRIPTION

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).
