Using OBS output device with DSLR as input device
Across two separate blog posts, I learnt how to use the v4l2loopback Linux kernel module to use my DSLR as a webcam alternative and the output of OBS / OBS Studio as a fake webcam:
- Using OBS Studio with V4L2 for Google Meet
- The blog post shows how to load the module once, but does not explain how to make sure it loads every time.
- How to Use Your DSLR Camera as a Webcam in Linux
In order to get the kernel module to load every time I reboot, I created the following files:
/etc/modprobe.d/v4l2loopback.confwith the following contents:options v4l2loopback devices=2 video_nr=10,11 card_label="OBS Cam,Canon 60D" exclusive_caps=1 max_buffers=2- The video devices are namely
/dev/video10for the “OBS Cam” output and/dev/video11for the “Canon 60D” input.
- The video devices are namely
/etc/modules-load.d/v4l2loopback.confwith the following contents:v4l2loopback
I also created an alias in my .bash_aliases file to activate the DSLR as an input device:
alias 60D='gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video11'
This way, I need to type 60D in my terminal to accept the camera’s input.
