I'm using OBS Studio and would like to have a virtual video output saved permanently so that it can be run when the application is launched.
This command creates the virtual output:
sudo modprobe v4l2loopback video_nr=10 card_label="OBS Video Source" exclusive_caps=1
But I must run the command in console on each boot. How can I make this permanent? The plugin that utilizes the output in OBS Studio is configured to auto start but
/dev/video10 is not available after a reboot of the system.
$ modinfo v4l2loopback | grep -i parm parm: debug:debugging level (higher values == more verbose) (int) parm: max_buffers:how many buffers should be allocated (int) parm: max_openers:how many users can open loopback device (int) parm: devices:how many devices should be created (int) parm: video_nr:video device numbers (-1=auto, 0=/dev/video0, etc.) (array of int) parm: card_label:card labels for every device (array of charp) parm: exclusive_caps:whether to announce OUTPUT/CAPTURE capabilities exclusively or not (array of bool) parm: max_width:maximum frame width (int) parm: max_height:maximum frame height (int)
