QtScrcpy supports displaying and controlling Android devices via USB or over network. It does NOT require root privileges.

It supports three major platforms: GNU/Linux, Windows and macOS.

It focuses on:

  • lightness (displays only the device screen)
  • performance (30~60 fps)
  • quality (1920×1080 or above)
  • low latency (35~70ms)
  • low startup time (only about 1 second to display the first frame)
  • non-intrusiveness (nothing will be installed on the device)

The author has developed a more professional screen casting software called QuickMirror

QuickMirror function&features:

  • Equipment screen casting&control: batch screen casting, individual control, batch control
  • Group management
  • WiFi screen mirroring/OTG screen mirroring
  • Adb shell shortcut command
  • File transfer, apk installation
  • Multiple screen mirroring: In OTG mirroring mode, with low resolution and smoothness settings, a single computer can manage 500+phones simultaneously
  • Low latency: USB screen mirroring 1080p latency is within 30ms, which is lower than all screen mirroring software on the market in terms of latency at the same resolution and smoothness
  • Low CPU usage: pure C++development, high-performance GPU video rendering
  • High resolution: adjustable, maximum support for native resolution of Android terminals
  • Perfect Chinese input: Supports Xianyu app, supports Samsung phones
  • The free version can cast up to 10 screens, with unlimited functionality (except for automatic screen mirroring)

Mapping Keys

You can write your script to map keyboard and mouse actions to touches and clicks of the mobile phone according to your needs. Here are the script writing rules.

Script for TikTok and some other games are provided by default. Once enabled, you can play the game with your keyboard and mouse. The default key mapping for PUBG Mobile is as follows:

Instruction for adding new customized mapping files.

  • Write a customized script and put it in the keymap directory
  • Click refresh script to show it
  • Select your script
  • Connect to your phone, start service and click apply
  • Press ~ key (the SwitchKey in the key map script) to switch to custom mapping mode
  • Press the ~ key again to switch back to normal mode
  • (For games such as PUBG Mobile) If you want to move vehicles with the STEER_WHEEL keys, you need to set the move mode to single rocker mode.

If you don't know how to manually write mapping rules, you can also use the QuickAssistant developed by the author QuickAssistant Features&Functions:

  • Play Android mobile games smoothly through keyboard and mouse
  • Interface based editing of key mapping script
  • Support pausing the computer screen and using only keyboard and mouse operations
  • Screenshot&Recording of Mobile Screen
  • Simple batch control
  • Android 11+supports playing mobile audio on computers (under development...)
  • Mobile app installation free
  • Fast and instant connection
  • Low latency: USB screen mirroring 1080p latency is within 30ms, which is lower than all screen mirroring software on the market in terms of latency at the same resolution and smoothness
  • Low CPU usage: pure C++development, high-performance GPU video rendering
  • High resolution: adjustable, maximum support for native resolution of Android terminals

Thanks

QtScrcpy is based on Genymobile's scrcpy project. Thanks a lot!

The difference between QtScrcpy and the original scrcpy is as follows:

key points|scrcpy|QtScrcpy --|:--:|:--: ui|sdl|qt video encode|ffmpeg|ffmpeg video render|sdl|opengl cross-platform|self implemented|provided by Qt language|C|C++ style|sync|async keymap|no custom keymap|support custom keymap build|meson+gradle|qmake or CMake

  • It's very easy to customize your GUI with Qt
  • Asynchronous programming of Qt-based signal slot mechanism improves performance
  • Easy to learn
  • Add support for multi-touch
