USE flags for media-video/droidcam Use your phone or tablet as webcam with a v4l device driver and app
To use Droidcam, a smartphone with the Droidcam app installed is needed. The smartphone and the computer need to be able to reach each other over the network. Alternatively, a USB connection can be used. Depending on the operating system, this might require setting further options on the smartphone (e.g. enabling USB debugging).
Connect via Wi-Fi/LAN
After starting Droidcam on the smartphone, the smartphone app shows the IP address and port for the computer to connect to.
After starting the app on the computer,
WiFi / LAN needs to be selected and the WiFi IP and port, which are shown on the smartphone, need to be entered in the appropriate field on the computer.
After that, the two apps should be able to establish a connection.
The phone's camera is then available like any other webcam connected to the computer.
