# scrcpy (v1.14)
|
||
|
||
This application provides display and control of Android devices connected on
|
||
USB (or [over TCP/IP][article-tcpip]). It does not require any _root_ access.
|
||
It works on _GNU/Linux_, _Windows_ and _macOS_.
|
||
|
||
|
||
|
||
It focuses on:
|
||
|
||
- **lightness** (native, displays only the device screen)
|
||
- **performance** (30~60fps)
|
||
- **quality** (1920×1080 or above)
|
||
- **low latency** ([35~70ms][lowlatency])
|
||
- **low startup time** (~1 second to display the first image)
|
||
- **non-intrusiveness** (nothing is left installed on the device)
|
||
|
||
[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
|
||
|
||
|
||
## Requirements
|
||
|
||
The Android device requires at least API 21 (Android 5.0).
|
||
|
||
Make sure you [enabled adb debugging][enable-adb] on your device(s).
|
||
|
||
[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
|
||
|
||
On some devices, you also need to enable [an additional option][control] to
|
||
control it using keyboard and mouse.
|
||
|
||

You could also [build the app manually][BUILD] (don't worry, it's not that
|
||
hard).
|
||
|
||
|
||
|
||
### Windows
|
||
|
||
For Windows, for simplicity, a prebuilt archive with all the dependencies
|
||
(including `adb`) is available:
|
||
|
||
- [`scrcpy-win64-v1.14.zip`][direct-win64]
|
||
_(SHA-256: 2be9139e46e29cf2f5f695848bb2b75a543b8f38be1133257dc5068252abc25f)_
|
||
|
||
[direct-win64]: https://github.com/Genymobile/scrcpy/releases/download/v1.14/scrcpy-win64-v1.14.zip
|
||
|
||
It is also available in [Chocolatey]:
|
||
|
||
[Chocolatey]: https://chocolatey.org/
|
||
|
||
```bash
|
||
choco install scrcpy
|
||
choco install adb # if you don't have it yet
|
||
```
|
||
|
||
And in [Scoop]:
|
||
|
||
```bash
|
||
scoop install scrcpy
|
||
scoop install adb # if you don't have it yet
|
||
```
|
||
|
||
[Scoop]: https://scoop.sh
|
||
|
||
You can also [build the app manually][BUILD].
|
||
|
||
|
||
### macOS
|
||
|
||
The application is available in [Homebrew]. Just install it:
|
||
|
||
[Homebrew]: https://brew.sh/
|
||
|
||
```bash
|
||
brew install scrcpy
|
||
```
|
||
|
||
You need `adb`, accessible from your `PATH`. If you don't have it yet:
|
||
|
||
```bash
|
||
brew cask install android-platform-tools
|
||
```
|
||
|
||
You can also [build the app manually][BUILD].
|
||
|
||
|
||
## Run
|
||
|
||
Plug an Android device, and execute:
|
||
|
||
```bash
|
||
scrcpy
|
||
```
|
||
|
||
It accepts command-line arguments, listed by:
|
||
|
||
```bash
|
||
scrcpy --help
|
||
```
|
||
|
||
## Features
|
||
|
||
### Capture configuration
|
||
|
||
#### Reduce size
|
||
|
||
Sometimes, it is useful to mirror an Android device at a lower definition to
|
||
increase performance.
|
||
|
||
To limit both the width and height to some value (e.g. 1024):
|
||
|
||
```bash
|
||
scrcpy --max-size 1024
|
||
scrcpy -m 1024 # short version
|
||
```
|
||
|
||
The other dimension is computed to that the device aspect ratio is preserved.
|
||
That way, a device in 1920×1080 will be mirrored at 1024×576.
|
||
|
||
|
||
#### Change bit-rate
|
||
|
||
The default bit-rate is 8 Mbps. To change the video bitrate (e.g. to 2 Mbps):
|
||
|
||
```bash
|
||
scrcpy --bit-rate 2M
|
||
scrcpy -b 2M # short version
|
||
```
|
||
|
||
#### Limit frame rate
|
||
|
||
The capture frame rate can be limited:
|
||
|
||
```bash
|
||
scrcpy --max-fps 15
|
||
```
|
||
|
||
This is officially supported since Android 10, but may work on earlier versions.
|
||
|
||
#### Crop
|
||
|
||
The device screen may be cropped to mirror only part of the screen.
|
||
|
||
This is useful for example to mirror only one eye of the Oculus Go:
|
||
|
||
```bash
|
||
scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)
|
||
```
|
||
|
||
If `--max-size` is also specified, resizing is applied after cropping.
|
||
|
||
|
||
#### Lock video orientation
|
||
|
||
|
||
To lock the orientation of the mirroring:
|
||
|
||
```bash
|
||
scrcpy --lock-video-orientation 0 # natural orientation
|
||
scrcpy --lock-video-orientation 1 # 90° counterclockwise
|
||
scrcpy --lock-video-orientation 2 # 180°
|
||
scrcpy --lock-video-orientation 3 # 90° clockwise
|
||
```
|
||
|
||
This affects recording orientation.
|
||
|
||
|
||
### Recording
|
||
|
||
It is possible to record the screen while mirroring:
|
||
|
||
```bash
|
||
scrcpy --record file.mp4
|
||
scrcpy -r file.mkv
|
||
```
|
||
|
||
To disable mirroring while recording:
|
||
|
||
```bash
|
||
scrcpy --no-display --record file.mp4
|
||
scrcpy -Nr file.mkv
|
||
# interrupt recording with Ctrl+C
|
||
```
|
||
|
||
"Skipped frames" are recorded, even if they are not displayed in real time (for
|
||
performance reasons). Frames are _timestamped_ on the device, so [packet delay
|
||
variation] does not impact the recorded file.
|
||
|
||
[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
|
||
|
||
|
||
### Connection
|
||
|
||
#### Wireless
|
||
|
||
_Scrcpy_ uses `adb` to communicate with the device, and `adb` can [connect] to a
|
||
device over TCP/IP:
|
||
|
||
1. Connect the device to the same Wi-Fi as your computer.
|
||
2. Get your device IP address (in Settings → About phone → Status).
|
||
3. Enable adb over TCP/IP on your device: `adb tcpip 5555`.
|
||
4. Unplug your device.
|
||
5. Connect to your device: `adb connect DEVICE_IP:5555` _(replace `DEVICE_IP`)_.
|
||
6. Run `scrcpy` as usual.
|
||
|
||
It may be useful to decrease the bit-rate and the definition:
|
||
|
||
```bash
|
||
scrcpy --bit-rate 2M --max-size 800
|
||
scrcpy -b2M -m800 # short version
|
||
```
|
||
|
||
[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
|
||
|
||
|
||
#### Multi-devices
|
||
|
||
If several devices are listed in `adb devices`, you must specify the _serial_:
|
||
|
||
```bash
|
||
scrcpy --serial 0123456789abcdef
|
||
scrcpy -s 0123456789abcdef # short version
|
||
```
|
||
|
||
If the device is connected over TCP/IP:
|
||
|
||
```bash
|
||
scrcpy --serial 192.168.0.1:5555
|
||
scrcpy -s 192.168.0.1:5555 # short version
|
||
```
|
||
|
||
You can start several instances of _scrcpy_ for several devices.
|
||
|
||
#### Autostart on device connection
|
||
|
||
You could use [AutoAdb]:
|
||
|
||
```bash
|
||
autoadb scrcpy -s '{}'
|
||
```
|
||
|
||
[AutoAdb]: https://github.com/rom1v/autoadb
|
||
|
||
#### SSH tunnel
|
||
|
||
To connect to a remote device, it is possible to connect a local `adb` client to
|
||
a remote `adb` server (provided they use the same version of the _adb_
|
||
protocol):
|
||
|
||
```bash
|
||
adb kill-server # kill the local adb server on 5037
|
||
ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
|
||
# keep this open
|
||
```
|
||
|
||
From another terminal:
|
||
|
||
```bash
|
||
scrcpy
|
||
```
|
||
|
||
To avoid enabling remote port forwarding, you could force a forward connection
|
||
instead (notice the `-L` instead of `-R`):
|
||
|
||
```bash
|
||
adb kill-server # kill the local adb server on 5037
|
||
ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
|
||
# keep this open
|
||
```
|
||
|
||
From another terminal:
|
||
|
||
```bash
|
||
scrcpy --force-adb-forwrad
|
||
```
|
||
|
||
|
||
Like for wireless connections, it may be useful to reduce quality:
|
||
|
||
```
|
||
scrcpy -b2M -m800 --max-fps 15
|
||
```
|
||
|
||
### Window configuration
|
||
|
||
#### Title
|
||
|
||
By default, the window title is the device model. It can be changed:
|
||
|
||
```bash
|
||
scrcpy --window-title 'My device'
|
||
```
|
||
|
||
#### Position and size
|
||
|
||
The initial window position and size may be specified:
|
||
|
||
```bash
|
||
scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
|
||
```
|
||
|
||
#### Borderless
|
||
|
||
To disable window decorations:
|
||
|
||
```bash
|
||
scrcpy --window-borderless
|
||
```
|
||
|
||
#### Always on top
|
||
|
||
To keep the scrcpy window always on top:
|
||
|
||
```bash
|
||
scrcpy --always-on-top
|
||
```
|
||
|
||
#### Fullscreen
|
||
|
||
The app may be started directly in fullscreen:
|
||
|
||
```bash
|
||
scrcpy --fullscreen
|
||
scrcpy -f # short version
|
||
```
|
||
|
||
Fullscreen can then be toggled dynamically with `Ctrl`+`f`.
|
||
|
||
#### Rotation
|
||
|
||
The window may be rotated:
|
||
|
||
```bash
|
||
scrcpy --rotation 1
|
||
```
|
||
|
||
Possibles values are:
|
||
- `0`: no rotation
|
||
- `1`: 90 degrees counterclockwise
|
||
- `2`: 180 degrees
|
||
- `3`: 90 degrees clockwise
|
||
|
||
The rotation can also be changed dynamically with `Ctrl`+`←` _(left)_ and
|
||
`Ctrl`+`→` _(right)_.
|
||
|
||
Note that _scrcpy_ manages 3 different rotations:
|
||
- `Ctrl`+`r` requests the device to switch between portrait and landscape (the
|
||
current running app may refuse, if it does support the requested
|
||
orientation).
|
||
- `--lock-video-orientation` changes the mirroring orientation (the orientation
|
||
of the video sent from the device to the computer). This affects the
|
||
recording.
|
||
- `--rotation` (or `Ctrl`+`←`/`Ctrl`+`→`) rotates only the window content. This
|
||
affects only the display, not the recording.
|
||
|
||
|
||
### Other mirroring options
|
||
|
||
#### Read-only
|
||
|
||
To disable controls (everything which can interact with the device: input keys,
|
||
mouse events, drag&drop files):
|
||
|
||
```bash
|
||
scrcpy --no-control
|
||
scrcpy -n
|
||
```
|
||
|
||
#### Display
|
||
|
||
If several displays are available, it is possible to select the display to
|
||
mirror:
|
||
|
||
```bash
|
||
scrcpy --display 1
|
||
```
|
||
|
||
The list of display ids can be retrieved by:
|
||
|
||
```
|
||
adb shell dumpsys display # search "mDisplayId=" in the output
|
||
```
|
||
|
||
The secondary display may only be controlled if the device runs at least Android
|
||
10 (otherwise it is mirrored in read-only).
|
||
|
||
|
||
#### Stay awake
|
||
|
||
To prevent the device to sleep after some delay when the device is plugged in:
|
||
|
||
```bash
|
||
scrcpy --stay-awake
|
||
scrcpy -w
|
||
```
|
||
|
||
The initial state is restored when scrcpy is closed.
|
||
|
||
|
||
#### Turn screen off
|
||
|
||
It is possible to turn the device screen off while mirroring on start with a
|
||
command-line option:
|
||
|
||
```bash
|
||
scrcpy --turn-screen-off
|
||
scrcpy -S
|
||
```
|
||
|
||
Or by pressing `Ctrl`+`o` at any time.
|
||
|
||
To turn it back on, press `Ctrl`+`Shift`+`o` (or `POWER`, `Ctrl`+`p`).
|
||
|
||
It can be useful to also prevent the device to sleep:
|
||
|
||
```bash
|
||
scrcpy --turn-screen-off --stay-awake
|
||
scrcpy -Sw
|
||
```
|
||
|
||
|
||
#### Render expired frames
|
||
|
||
By default, to minimize latency, _scrcpy_ always renders the last decoded frame
|
||
available, and drops any previous one.
|
||
|
||
To force the rendering of all frames (at a cost of a possible increased
|
||
latency), use:
|
||
|
||
```bash
|
||
scrcpy --render-expired-frames
|
||
```
|
||
|
||
#### Show touches
|
||
|
||
For presentations, it may be useful to show physical touches (on the physical
|
||
device).
|
||
|
||
Android provides this feature in _Developers options_.
|
||
|
||
_Scrcpy_ provides an option to enable this feature on start and restore the
|
||
initial value on exit:
|
||
|
||
```bash
|
||
scrcpy --show-touches
|
||
scrcpy -t
|
||
```
|
||
|
||
Note that it only shows _physical_ touches (with the finger on the device).
|
||
|
||
|
||
#### Disable screensaver
|
||
|
||
By default, scrcpy does not prevent the screensaver to run on the computer.
|
||
|
||
To disable it:
|
||
|
||
```bash
|
||
scrcpy --disable-screensaver
|
||
```
|
||
|
||
|
||
### Input control
|
||
|
||
#### Rotate device screen
|
||
|
||
Press `Ctrl`+`r` to switch between portrait and landscape modes.
|
||
|
||
Note that it rotates only if the application in foreground supports the
|
||
requested orientation.
|
||
|
||
#### Copy-paste
|
||
|
||
It is possible to synchronize clipboards between the computer and the device, in
|
||
both directions:
|
||
|
||
- `Ctrl`+`c` copies the device clipboard to the computer clipboard;
|
||
- `Ctrl`+`Shift`+`v` copies the computer clipboard to the device clipboard (and
|
||
pastes if the device runs Android >= 7);
|
||
- `Ctrl`+`v` _pastes_ the computer clipboard as a sequence of text events (but
|
||
breaks non-ASCII characters).
|
||
|
||
Moreover, any time the Android clipboard changes, it is automatically
|
||
synchronized to the computer clipboard.
|
||
|
||
#### Text injection preference
|
||
|
||
There are two kinds of [events][textevents] generated when typing text:
|
||
- _key events_, signaling that a key is pressed or released;
|
||
- _text events_, signaling that a text has been entered.
|
||
|
||
By default, letters are injected using key events, so that the keyboard behaves
|
||
as expected in games (typically for WASD keys).
|
||
|
||
But this may [cause issues][prefertext]. If you encounter such a problem, you
|
||
can avoid it by:
|
||
|
||
```bash
|
||
scrcpy --prefer-text
|
||
```
|
||
|
||
(but this will break keyboard behavior in games)

|
||
|
||
|
||
### File drop
|
||
|
||
#### Install APK
|
||
|
||
To install an APK, drag & drop an APK file (ending with `.apk`) to the _scrcpy_
|
||
window.
|
||
|
||
There is no visual feedback, a log is printed to the console.
|
||
|
||
|
||
#### Push file to device
|
||
|
||
To push a file to `/sdcard/` on the device, drag & drop a (non-APK) file to the
|
||
_scrcpy_ window.
|
||
|
||
There is no visual feedback, a log is printed to the console.
|
||
|
||
The target directory can be changed on start:
|
||
|
||
```bash
|
||
scrcpy --push-target /sdcard/foo/bar/
|
||
```
|
||
|
||
|
||
### Audio forwarding
|
||
|
||
Audio is not forwarded by _scrcpy_. Use [USBaudio] (Linux-only).
|
||
|
||
Also see [issue #14].

## Custom paths
|
||
|
||
To use a specific _adb_ binary, configure its path in the environment variable
|
||
`ADB`:
|
||
|
||
ADB=/path/to/adb scrcpy
|
||
|
||
To override the path of the `scrcpy-server` file, configure its path in
|
||
`SCRCPY_SERVER_PATH`.

## Why _scrcpy_?
|
||
|
||
A colleague challenged me to find a name as unpronounceable as [gnirehtet].
|
||
|
||
[`strcpy`] copies a **str**ing; `scrcpy` copies a **scr**een.
