# scrcpy (v1.8)
|
||
|
||
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_.
|
||
|
||
|
||
|
||
|
||
## Requirements
|
||
|
||
The Android part 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.

|
||
|
||
|
||
## Get the app
|
||
|
||
|
||
### Linux
|
||
|
||
On Linux, you typically need to [build the app manually][BUILD]. Don't worry,
|
||
it's not that hard.
|
||
|
||
For Arch Linux, an [AUR] package is available: [`scrcpy`][aur-link].
|
||
|
||
[AUR]: https://wiki.archlinux.org/index.php/Arch_User_Repository
|
||
[aur-link]: https://aur.archlinux.org/packages/scrcpy/
|
||
|
||
For Gentoo, an [Ebuild] is available: [`scrcpy/`][ebuild-link].
|
||
|
||
[Ebuild]: https://wiki.gentoo.org/wiki/Ebuild
|
||
[ebuild-link]: https://github.com/maggu2810/maggu2810-overlay/tree/master/app-mobilephone/scrcpy
|
||
|
||
|
||
### Windows
|
||
|
||
For Windows, for simplicity, prebuilt archives with all the dependencies
|
||
(including `adb`) are available:
|
||
|
||
- [`scrcpy-win32-v1.8.zip`][direct-win32]
|
||
_(SHA-256: c0c29ed1c66deaa73bdadacd09e598aafb3a117929cf7a314cce1cc45e34de53)_
|
||
- [`scrcpy-win64-v1.8.zip`][direct-win64]
|
||
_(SHA-256: 9cc980d07bd8f036ae4e91d0bc6fc3281d7fa8f9752d4913b643c0fb72a19fb7)_
|
||
|
||
[direct-win32]: https://github.com/Genymobile/scrcpy/releases/download/v1.8/scrcpy-win32-v1.8.zip
|
||
[direct-win64]: https://github.com/Genymobile/scrcpy/releases/download/v1.8/scrcpy-win64-v1.8.zip
|
||
|
||
You can also [build the app manually][BUILD].
|
||
|
||
|
||
### Mac OS
|
||
|
||
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
|
||
|
||
|
||
### Reduce size
|
||
|
||
Sometimes, it is useful to mirror an Android device at a lower definition to
|
||
increase performances.
|
||
|
||
To limit both 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 8Mbps. To change the video bitrate (e.g. to 2Mbps):
|
||
|
||
```bash
|
||
scrcpy --bit-rate 2M
|
||
scrcpy -b 2M # short version
|
||
```
|
||
|
||
|
||
### Crop
|
||
|
||
The device screen may be cropped to mirror only part of the screen.
|
||
|
||
This is useful for example to mirror only 1 eye of the Oculus Go:
|
||
|
||
```bash
|
||
scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)
|
||
scrcpy -c 1224:1440:0:0 # short version
|
||
```
|
||
|
||
If `--max-size` is also specified, resizing is applied after cropping.
|
||
|
||
|
||
### 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
|
||
|
||
|
||
### Record screen
|
||
|
||
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
|
||
# Ctrl+C does not terminate properly on Windows, so disconnect the device
|
||
```
|
||
|
||
"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
|
||
|
||
|
||
### Multi-devices
|
||
|
||
If several devices are listed in `adb devices`, you must specify the _serial_:
|
||
|
||
```bash
|
||
scrcpy --serial 0123456789abcdef
|
||
scrcpy -s 0123456789abcdef # short version
|
||
```
|
||
|
||
You can start several instances of _scrcpy_ for several devices.
|
||
|
||
|
||
### 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`.
|
||
|
||
|
||
### Always on top
|
||
|
||
The window of app can always be above others by:
|
||
|
||
```bash
|
||
scrcpy --always-on-top
|
||
scrcpy -T # short version
|
||
```
|
||
|
||
|
||
### 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 disable on exit:
|
||
|
||
```bash
|
||
scrcpy --show-touches
|
||
scrcpy -t
|
||
```
|
||
|
||
Note that it only shows _physical_ touches (with the finger on the device).
|
||
|
||
|
||
### 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.
|
||
|
||
|
||
### 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
|
||
```
|
||
|
||
|
||
### Forward audio
|
||
|
||
Audio is not forwarded by _scrcpy_.
|
||
|
||
There is a limited solution using [AOA], implemented in the [`audio`] branch. If
|
||
you are interested, 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.jar` file (it can be [useful] on
|
||
Windows), 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.
