**This GitHub repo () is the only official source for the project. Do not download releases from random websites, even if their name contains `scrcpy`.** # scrcpy (v2.7) scrcpy _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_. ![screenshot](assets/screenshot-debian-600.jpg) 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) - [virtual display](doc/virtual_display.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][hid-keyboard] and [mouse][hid-mouse] simulation (HID) - [gamepad](doc/gamepad.md) support - [OTG mode](doc/otg.md) - and more… [hid-keyboard]: doc/keyboard.md#physical-keyboard-simulation [hid-mouse]: doc/mouse.md#physical-mouse-simulation ## 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 (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][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/otg.md). ## Get the app - [Linux](doc/linux.md) - [Windows](doc/windows.md) - [macOS](doc/macos.md) ## Usage examples There are a lot of options, [documented](#user-documentation) 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: ```bash 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 ``` - Start VLC in a new virtual display (separate from the device display): ```bash scrcpy --new-display=1920x1080 --start-app=org.videolan.vlc ``` - Record the device camera in H.265 at 1920x1080 (and microphone) to an MP4 file: ```bash 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): ```bash 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): ```bash scrcpy --otg ``` - Control the device using gamepad controllers plugged into the computer: ```bash scrcpy --gamepad=uhid scrcpy -G # short version ``` ## User documentation The application provides a lot of features and configuration options.
