scrcpy - Display and control your Android device

scrcpy [options]

scrcpy provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access.

Make scrcpy window always on top (above other windows).
Encode the video at the given bit-rate, expressed in bits/s. Unit suffixes are supported: 'K' (x1000) and 'M' (x1000000).

Default is 8000000.

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 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.

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

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

Disable screensaver while scrcpy is running.
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.

Add a buffering delay (in milliseconds) before displaying. This increases latency to compensate for jitter.

Default is 0 (no buffering).

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

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

Use a specific MediaCodec encoder (must be a H.264 encoder).
Do not attempt to use "adb reverse" to connect to the device.
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.
Start in fullscreen.
Print this help.
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.

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 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".

Limit the framerate of screen capture (officially supported since Android 10, but may work on earlier versions).
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).

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.

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.

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.

By default, on MediaCodec error, scrcpy automatically tries again with a lower definition.

This option disables this behavior.

Disable device control (mirror the device in read-only).
Do not display device (only when screen recording is enabled).
Do not forward repeated key events when a key is held down.
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.
Do not power on the device on start.
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.

Set the TCP port (range) used by the client to listen.

Default is 27183:27199.

Turn the device screen off when closing scrcpy.
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).

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

Inject key events for all input keys, and ignore text events.
Record screen to file.

The format is determined by the --record-format option if set, or by the file extension (.mp4 or .mkv).

Force recording format (either mp4 or mkv).
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

Set the initial display rotation. Possibles values are 0, 1, 2 and 3. Each increment adds a 90 degrees rotation counterclockwise.
The device serial number. Mandatory only if several devices are connected to adb.
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).

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.

Turn the device screen off immediately.
Enable "show touches" on start, restore the initial value on exit.

It only shows physical touches (not clicks from scrcpy).

Set the IP address of the adb tunnel to reach the scrcpy server. This option automatically enables --force-adb-forward.

Default is localhost.

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.

Output to v4l2loopback device.

It requires to lock the video orientation (see --lock-video-orientation).

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).

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

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

Print the version of scrcpy.
Keep the device on while scrcpy is running, when the device is plugged in.
Disable window decorations (display borderless window).
Set a custom window title.
Set the initial window horizontal position.

Default is "auto".

Set the initial window vertical position.

Default is "auto".

Set the initial window width.

Default is 0 (automatic).

Set the initial window height.

Default is 0 (automatic).

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.

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).
