# scrcpy (v2.3.1)

_pronounced "**scr**een **c**o**py**"_

This application mirrors Android devices (video and audio) connected via
USB or [over TCP/IP](doc/connection.md#tcpip-wireless), and allows to control the
device with the keyboard and the mouse of the computer. It does not require any
_root_ access. It works on _Linux_, _Windows_ and _macOS_.

It focuses on:

- **lightness**: native, displays only the device screen
 - **performance**: 30~120fps, depending on the device
 - **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 Android device
 - **user benefits**: no account, no ads, no internet required
 - **freedom**: free and open source software

[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646

Its features include:
 - [audio forwarding](doc/audio.md) (Android 11+)
 - [recording](doc/recording.md)
 - mirroring with [Android device screen off](doc/device.md#turn-screen-off)
 - [copy-paste](doc/control.md#copy-paste) in both directions
 - [configurable quality](doc/video.md)
 - [camera mirroring](doc/camera.md) (Android 12+)
 - [mirroring as a webcam (V4L2)](doc/v4l2.md) (Linux-only)
 - [physical keyboard/mouse simulation (HID)](doc/hid-otg.md)
 - [OTG mode](doc/hid-otg.md#otg)
 - and more…

## Prerequisites

The Android device requires at least API 21 (Android 5.0).

[Audio forwarding](doc/audio.md) is supported for API >= 30 (Android 11+).

Make sure you [enabled USB debugging][enable-adb] on your device(s).

[enable-adb]: https://developer.android.com/studio/debug/dev-options#enable

On some devices, you also need to enable [an additional option][control] `USB
debugging (Security Settings)` (this is an item different from `USB debugging`)
to control it using a keyboard and mouse. Rebooting the device is necessary once
this option is set.

[control]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323

Note that USB debugging is not required to run scrcpy in [OTG
mode](doc/hid-otg.md#otg).
