scrcpy --record=recording.mp4

scrcpy --record=recording.mp4 --no-audio

Tips

Reduce latency

Use a shorter USB cable and avoid USB hubs when possible. Lower resolution can also improve performance.

Save battery

Use --turn-screen-off to mirror and control your device while the phone screen stays off.

Multiple devices

If multiple devices are connected, use scrcpy -s <serial> to select one. Run adb devices to see serial numbers.

Copy-paste

SCRCPY syncs clipboard bidirectionally. Copy on your computer and paste in an app on your device (and vice versa).

Troubleshooting

Issue Solution
Input lag Lower resolution with -m 1024 or reduce bitrate
Audio not working Ensure Android 11+ for audio forwarding
Wireless disconnects Keep device and computer on same Wi-Fi network
Window too large Use -m 1280 to limit max dimension
