If you need several independent loopback devices, you can pass the “devices” option, when loading the module; e.g.

\n
\n
\n

# modprobe v4l2loopback devices=4
\nWill give you 4 loopback devices (e.g. /dev/video1 \u2026\u200b /dev/video5)

\n
\n
\n

You can also specify the device IDs manually; e.g.

\n
\n
\n

# modprobe v4l2loopback video_nr=3,4,7
\nWill create 3 devices (/dev/video3, /dev/video4 & /dev/video7)

\n
\n
\n

# modprobe v4l2loopback video_nr=3,4,7 card_label=”device number 3″,”the number four”,”the last one”
\nWill create 3 devices with the card names passed as the second parameter:

\n
\n
\n

/dev/video3 \u2192 device number 3
\n/dev/video4 \u2192 the number four
\n/dev/video7 \u2192 the last one
