scrcpy (v2.7)

pronounced "screen copy"

This application mirrors Android devices (video and audio) connected via
USB or over TCP/IP, 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
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

Its features include:

audio forwarding (Android 11+)
recording
mirroring with Android device screen off
copy-paste in both directions
configurable quality
camera mirroring (Android 12+)
mirroring as a webcam (V4L2) (Linux-only)
physical keyboard and mouse simulation (HID)
gamepad support
OTG mode
and more…

Prerequisites

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

Audio forwarding is supported for API >= 30 (Android 11+).

Make sure you enabled USB debugging on your device(s).

On some devices (especially Xiaomi), you might get the following error:

java.lang.SecurityException: Injecting input events requires the caller (or the source of the instrumentation, if any) to have the INJECT_EVENTS permission.

In that case, you need to enable an additional option 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.

Note that USB debugging is not required to run scrcpy in OTG mode.

Usage examples

There are a lot of options, documented in separate pages.
Here are just some common examples.

Capture the screen in H.265 (better quality), limit the size to 1920, limit
the frame rate to 60fps, disable audio, and control the device by simulating
a physical keyboard:
```
scrcpy --video-codec=h265 --max-size=1920 --max-fps=60 --no-audio --keyboard=uhid
scrcpy --video-codec=h265 -m1920 --max-fps=60 --no-audio -K  # short version
```

Record the device camera in H.265 at 1920x1080 (and microphone) to an MP4
file:

scrcpy --video-source=camera --video-codec=h265 --camera-size=1920x1080 --record=file.mp4

Capture the device front camera and expose it as a webcam on the computer (on
Linux):

scrcpy --video-source=camera --camera-size=1920x1080 --camera-facing=front --v4l2-sink=/dev/video2 --no-playback

Control the device without mirroring by simulating a physical keyboard and
mouse (USB debugging not required):
```
scrcpy --otg
```
Control the device using gamepad controllers plugged into the computer:
```
scrcpy --gamepad=uhid
scrcpy -G  # short version
```
