You must install the module v4l2loopback by
sudo apt install v4l2loopback-dkms.
To create a v4l2 device: sudo modprobe v4l2loopback
To start scrcpy using a v4l2 sink:
scrcpy –v4l2-sink=/dev/videoN
scrcpy –v4l2-sink=/dev/videoN –no-display # disable mirroring window
scrcpy –v4l2-sink=/dev/videoN -N # short version(replace N with the device ID, check with ls /dev/video*)
Once enabled, you can open your video stream with a v4l2-capable tool:
