Ws-scrcpy
| Problem | Likely Solution |
|---------|------------------|
| Device not detected | Run adb devices to verify connection; restart ADB server (adb kill-server && adb start-server) |
| Black screen on some browsers | Ensure browser supports H.264 decoding; try Chrome/Edge instead of Firefox |
| High latency | Switch to WebSocket mode (not WebRTC) on local networks; reduce video quality |
| Audio not streaming | ws-scrcpy doesn't support audio streaming by default (scrcpy limitation) – use separate audio forwarding |
| Multiple users cause lag | Limit concurrent streams via --max-clients 5; upgrade server CPU for video encoding |
npm install -g ws-scrcpy
ws-scrcpy
Multiple users can connect to the same device at once – perfect for collaborative debugging, training, or presentations.
For slow connections (e.g., mobile hotspots), lower the video quality. ws-scrcpy
ws-scrcpy --max-size 1024 --bit-rate 2M
Once the server is running and devices are connected:
ws-scrcpy isn't just a simple port of scrcpy – it expands upon it with unique capabilities: Multiple users can connect to the same device
Even the best tools have hiccups. Here is how to solve the top 3 problems.
Understanding the architecture demystifies the setup process. Once the server is running and devices are connected:
Because WebSockets support full-duplex communication, latency remains extremely low—typically under 50ms on a local network.
