ws scrcpy

Web client prototype for scrcpy.

Requirements

Browser must support the following technologies:

• WebSockets
• Media Source Extensions and h264 decoding (MseDecoder)
• WebWorkers tinyh264)
• WebAssembly (Broadway.js and tinyh264)

Server:

• Node.js v10+
• node-gyp (on Window: npm install --global windows-build-tools node-gyp)
• adb executable must be available in the PATH environment variable

Device:

• Android 5.0+ (API 21+)
• Enabled debugging
• On some devices, you also need to enable an additional option to control it using keyboard and mouse.

Build and Start

git clone https://github.com/NetrisTV/ws-scrcpy.git
cd ws-scrcpy
npm install
npm start

Supported features

Screen casting

The modified version of Genymobile/scrcpy used to stream H264 video, which then decoded by one of included decoders.

Remote control

• Touch events (including multi-touch)
• Multi-touch emulation: CTRL to start with center at the center of the screen, SHIFT + CTRL to start with center at the current point
• Capturing keyboard events
• Injecting text (ASCII only)
• Copy to/from device clipboard
• Device "rotation"

File push

Drag & drop an APK file to push it to the /data/local/tmp directory. You can install it manually from the included xterm.js terminal emulator.

Known issues

• New versions are most likely not incompatible with previous ones. If you do upgrade, then manually stop app_process or just reboot the device.
• The server on the Android Emulator listens on the internal interface and not available from the outside (as workaround you can do adb forward tcp:8886 tcp:8886 and use 127.0.0.1 instead of emulator IP address)
• Tinyh264Decoder may fail to start, try to reload the page.
• MseDecoder reports too many dropped frames in quality statistics: needs further investigation.

Security warning

Be advised and keep in mind:

• There is no encryption between browser and node.js server (plain HTTP).
• There is no encryption between browser and WebSocket server (plain WS).
• There is no authorization on any level.
• The modified version of scrcpy with integrated WebSocket server is listening for connections on all network interfaces.
• The modified version of scrcpy will keep running after the last client disconnected.

WS QVH

This project also contains front-end for NetrisTV/ws-qvh - application for screen streaming and control of iOS devices in a browser.

Run this to build it:

npm install
npm run dist:qvhack:frontend
