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 audio at the given bit rate, expressed in bits/s. Unit suffixes are supported: 'K' (x1000) and 'M' (x1000000).

Default is 128K (128000).

Configure the audio buffering delay (in milliseconds).

Lower values decrease the latency, but increase the likelyhood of buffer underrun (causing audio glitches).

Default is 50.

Select an audio codec (opus, aac, flac or raw).

Default is opus.

Set a list of comma-separated key:type=value options for the device audio 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

Use a specific MediaCodec audio encoder (depending on the codec provided by --audio-codec).

The available encoders can be listed by --list-encoders.

Select the audio source (output or mic).

Default is output.

Configure the size of the SDL audio output buffer (in milliseconds).

If you get "robotic" audio playback, you should test with a higher value (10). Do not change this setting otherwise.

Default is 5.

Encode the video at the given bit rate, expressed in bits/s. Unit suffixes are supported: 'K' (x1000) and 'M' (x1000000).

Default is 8M (8000000).

Select the camera size by its aspect ratio (+/- 10%).

Possible values are "sensor" (use the camera sensor aspect ratio), "num:den" (e.g. "4:3") and "value" (e.g. "1.6").

Enable high-speed camera capture mode.

This mode is restricted to specific resolutions and frame rates, listed by --list-camera-sizes.

Specify the device camera id to mirror.

The available camera ids can be listed by --list-cameras.

Select the device camera by its facing direction.

Possible values are "front", "back" and "external".

Specify the camera capture frame rate.

If not specified, Android's default frame rate (30 fps) is used.

Specify an explicit camera capture size.
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.
Add a buffering delay (in milliseconds) before displaying. This increases latency to compensate for jitter.

Default is 0 (no buffering).

Specify the device display id to mirror.

The available display ids can be listed by --list-displays.

Default is 0.

Set the initial display orientation.

Possible values are 0, 90, 180, 270, flip0, flip90, flip180 and flip270. The number represents the clockwise rotation in degrees; the "flip" keyword applies a horizontal flip before the rotation.

Default is 0.

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

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

Start in fullscreen.
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.
Print this help.
Same as --keyboard=uhid.
Select how to send keyboard inputs to the device.

Possible values are "disabled", "sdk", "uhid" and "aoa":


- "disabled" does not send keyboard inputs to the device.
- "sdk" uses the Android system API to deliver keyboard events to applications.
- "uhid" simulates a physical HID keyboard using the Linux HID kernel module on the device.
- "aoa" simulates a physical HID keyboard using the AOAv2 protocol. It may only work over USB.

For "uhid" and "aoa", 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 using the shortcut MOD+k (except in OTG mode), or by executing:


adb shell am start -a android.settings.HARD_KEYBOARD_SETTINGS

This option is only available when the HID keyboard is enabled (or a physical keyboard is connected).

Also see --mouse.

Kill adb when scrcpy terminates.
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.

List the valid camera capture sizes.
List cameras available on the device.
List video and audio encoders available on the device.
List displays available on the device.
Lock capture video orientation to value.

Possible values are "unlocked", "initial" (locked to the initial orientation), 0, 90, 180, and 270. The values represent the clockwise rotation from the natural device orientation, in degrees.

Default is "unlocked".

Passing the option without argument is equivalent to passing "initial".

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).

Same as --mouse=uhid.
Limit the framerate of screen capture (officially supported since Android 10, but may work on earlier versions).
Select how to send mouse inputs to the device.

Possible values are "disabled", "sdk", "uhid" and "aoa":


- "disabled" does not send mouse inputs to the device.
- "sdk" uses the Android system API to deliver mouse events to applications.
- "uhid" simulates a physical HID mouse using the Linux HID kernel module on the device.
- "aoa" simulates a physical mouse using the AOAv2 protocol. It may only work over USB.

In "uhid" and "aoa" modes, 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.

Also see --keyboard.

Disable device control (mirror the device in read-only).
Disable video and audio playback on the computer (equivalent to --no-video-playback --no-audio-playback).
Disable audio forwarding.
Disable audio playback on the computer.
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.

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.
Disable video forwarding.
Disable video playback on the computer.
Same as --display-orientation=value --record-orientation=value.
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.

Configure pause on exit. Possible values are "true" (always pause on exit), "false" (never pause on exit) and "if-error" (pause only if an error occured).

This is useful to prevent the terminal window from automatically closing, so that error messages can be read.

Default is "false".

Passing the option without argument is equivalent to passing "true".

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/".

Record screen to file.

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

Inject key events for all input keys, and ignore text events.
Force recording format (mp4, mkv, m4a, mka, opus, aac, flac or wav).
Set the record orientation.

Possible values are 0, 90, 180 and 270. The number represents the clockwise rotation in degrees.

Default is 0.

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

By default, scrcpy mirrors only the video if audio capture fails on the device. This option makes scrcpy fail if audio is enabled but does not work.
The device serial number. Mandatory only if several devices are connected to adb.
Turn the device screen off immediately.
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).

Enable "show touches" on start, restore the initial value on exit.

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

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.

Set the maximum mirroring time, in seconds.
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.

Print the version of scrcpy.
Set the log level ("verbose", "debug", "info", "warn" or "error").

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

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).

Select a video codec (h264, h265 or av1).

Default is h264.

Set a list of comma-separated key:type=value options for the device video 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

Use a specific MediaCodec video encoder (depending on the codec provided by --video-codec).

The available encoders can be listed by --list-encoders.

Select the video source (display or camera).

Camera mirroring requires Android 12+.

Default is display.

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).
