Ubuntu Manpage: scrcpy - Display and control your Android device

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.

-d, --select-usb
Use USB device (if there is exactly one, like adb -d).

Also see -e (--select-tcpip).

--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).

-e, --select-tcpip
Use TCP/IP device (if there is exactly one, like adb -e).

Also see -d (--select-usb).

--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.

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).

Also see --hid-mouse.

--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).

-M, --hid-mouse
Simulate a physical mouse by using HID over AOAv2.

In this mode, the computer mouse is captured to control the device directly
(relative mouse mode).

LAlt, LSuper or RSuper toggle the capture mode, to give control of the mouse back
to the computer.

It may only work over USB.

Also see --hid-keyboard.

--no-cleanup
By default, scrcpy removes the server binary from the device and restores the
device state (show touches, stay awake and power mode) on exit.

This option disables this cleanup.

--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.

--no-downsize-on-error
By default, on MediaCodec error, scrcpy automatically tries again with a lower
definition.

This option disables this behavior.

-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.

--no-power-on
Do not power on the device on start.

--otg Run in OTG mode: simulate physical keyboard and mouse, 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.

LAlt, LSuper or RSuper toggle the mouse capture mode, to give control of the mouse
back to the computer.

If any of --hid-keyboard or --hid-mouse is set, only enable keyboard or mouse
respectively, otherwise enable both.

It may only work over USB.

See --hid-keyboard and --hid-mouse.

-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).

--print-fps
Start FPS counter, to print framerate logs to the console. It can be started or
stopped at any time with MOD+i.

--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
and adb port of the current device (typically connected over USB), enables TCP/IP
mode if necessary, 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).

EXIT STATUS

       scrcpy will exit with code 0 on normal  program  termination.  If  an  initial  connection
       cannot be established, the exit code 1 will be returned. If the device disconnects while a
       session is active, exit code 2 will be returned.

SHORTCUTS

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