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.

--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.

--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 -1 (unlocked), 0, 1, 2 and 3. Natural device orientation is 0, and each increment adds a 90 degrees otation counterclockwise.

Default is -1 (unlocked).

--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).

-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.

--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/".

-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".

--render-expired-frames

By default, to minimize latency, scrcpy always renders the last available decoded frame, and drops any previous ones. This flag forces to render all frames, at a cost of a possible increased latency.

--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).

-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).

-v, --version

Print the version of scrcpy.

-V, --verbosity value

Set the log level ("debug", "info", "warn" or "error").

Default is "info" for release builds, "debug" for debug builds.

-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).

SHORTCUTS

In the following list, MOD is the shortcut modifier. By default, it's (left) Alt or (left) Super, but it can be configured by --shortcut-mod (see above).

MOD+f

Switch fullscreen mode

MOD+Left

Rotate display left

MOD+Right

Rotate display right

MOD+g
