.TH "scrcpy" "1"
|
|
.SH NAME
|
|
scrcpy \- Display and control your Android device
|
|
|
|
|
|
.SH SYNOPSIS
|
|
.B scrcpy
|
|
.RI [ options ]
|
|
|
|
|
|
.SH DESCRIPTION
|
|
.B scrcpy
|
|
provides display and control of Android devices connected on USB (or over TCP/IP). It does not require any root access.
|
|
|
|
|
|
.SH OPTIONS
|
|
|
|
.TP
|
|
.B \-\-always\-on\-top
|
|
Make scrcpy window always on top (above other windows).
|
|
|
|
.TP
|
|
.BI "\-b, \-\-bit\-rate " value
|
|
Encode the video at the given bit\-rate, expressed in bits/s. Unit suffixes are supported: '\fBK\fR' (x1000) and '\fBM\fR' (x1000000).
|
|
|
|
Default is 8000000.
|
|
|
|
.TP
|
|
.BI "\-\-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
|
|
.UR https://d.android.com/reference/android/media/MediaFormat
|
|
.UE .
|
|
|
|
.TP
|
|
.BI "\-\-crop " width\fR:\fIheight\fR:\fIx\fR:\fIy
|
|
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
|
|
.B \-\-max\-size
|
|
value is computed on the cropped size.
|
|
|
|
.TP
|
|
.BI "\-\-disable-screensaver"
|
|
Disable screensaver while scrcpy is running.
|
|
|
|
.TP
|
|
.BI "\-\-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.
|
|
|
|
.TP
|
|
.BI "\-\-display\-buffer ms
|
|
Add a buffering delay (in milliseconds) before displaying. This increases latency to compensate for jitter.
|
|
|
|
Default is 0 (no buffering).
|
|
|
|
.TP
|
|
.BI "\-\-encoder " name
|
|
Use a specific MediaCodec encoder (must be a H.264 encoder).
|
|
|
|
.TP
|
|
.B \-\-force\-adb\-forward
|
|
Do not attempt to use "adb reverse" to connect to the device.
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.B \-f, \-\-fullscreen
|
|
Start in fullscreen.
|
|
|
|
.TP
|
|
.B \-h, \-\-help
|
|
Print this help.
|
|
|
|
.TP
|
|
.B \-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).
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.BI "\-\-lock\-video\-orientation[=value]
|
|
Lock video orientation to \fIvalue\fR. 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".
|
|
|
|
.TP
|
|
.BI "\-\-max\-fps " value
|
|
Limit the framerate of screen capture (officially supported since Android 10, but may work on earlier versions).
|
|
|
|
.TP
|
|
.BI "\-m, \-\-max\-size " value
|
|
Limit both the width and height of the video to \fIvalue\fR. The other dimension is computed so that the device aspect\-ratio is preserved.
|
|
|
|
Default is 0 (unlimited).
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.B \-n, \-\-no\-control
|
|
Disable device control (mirror the device in read\-only).
|
|
|
|
.TP
|
|
.B \-N, \-\-no\-display
|
|
Do not display device (only when screen recording is enabled).
|
|
|
|
.TP
|
|
.B \-\-no\-key\-repeat
|
|
Do not forward repeated key events when a key is held down.
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
.TP
|
|
.BI "\-p, \-\-port " port[:port]
|
|
Set the TCP port (range) used by the client to listen.
|
|
|
|
Default is 27183:27199.
|
|
|
|
.TP
|
|
.B \-\-power\-off\-on\-close
|
|
Turn the device screen off when closing scrcpy.
|
|
|
|
.TP
|
|
.B \-\-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).
|
|
|
|
.TP
|
|
.BI "\-\-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/".
|
|
|
|
.TP
|
|
.B \-\-raw\-key\-events
|
|
Inject key events for all input keys, and ignore text events.
|
|
|
|
.TP
|
|
.BI "\-r, \-\-record " file
|
|
Record screen to
|
|
.IR file .
|
|
|
|
The format is determined by the
|
|
.B \-\-record\-format
|
|
option if set, or by the file extension (.mp4 or .mkv).
|
|
|
|
.TP
|
|
.BI "\-\-record\-format " format
|
|
Force recording format (either mp4 or mkv).
|
|
|
|
.TP
|
|
.BI "\-\-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".
|
|
|

|
|
.UE
|
|
|
|
.TP
|
|
.BI "\-\-rotation " value
|
|
Set the initial display rotation. Possibles values are 0, 1, 2 and 3. Each increment adds a 90 degrees rotation counterclockwise.
|
|
|
|
.TP
|
|
.BI "\-s, \-\-serial " number
|
|
The device serial number. Mandatory only if several devices are connected to adb.
|
|
|
|
.TP
|
|
.BI "\-\-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).
|
|
|
|
.TP
|
|
.BI "\-\-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.
|
|
|
|
.TP
|
|
.B \-S, \-\-turn\-screen\-off
|
|
Turn the device screen off immediately.
|
|
|
|
.TP
|
|
.B \-t, \-\-show\-touches
|
|

|
|
|
|
It only shows physical touches (not clicks from scrcpy).
|
|
|
|
.TP
|
|
.BI "\-\-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.
|
|
|
|
.TP
|
|
.BI "\-\-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.
|
|
|
|
.TP
|
|
.BI "\-\-v4l2-sink " /dev/videoN
|
|
Output to v4l2loopback device.
|
|
|
|
It requires to lock the video orientation (see \fB\-\-lock\-video\-orientation\fR).
|
|
|
|
.TP
|
|
.BI "\-\-v4l2-buffer " ms
|
|
Add a buffering delay (in milliseconds) before pushing frames. This increases latency to compensate for jitter.
|
|
|
|
This option is similar to \fB\-\-display\-buffer\fR, but specific to V4L2 sink.
|
|
|
|
Default is 0 (no buffering).
|
