Just ran into this tweet, on a new Snapchat "snapcamera" feature that so functions like an effect-applying loopback device.
Snapchat filters for EVERY video conferencing app on your computer via virtual camera!

Loopback ftw!

On Windows, there's a Virtual Camera plugin for OBS that works rather well (honestly better than most virtual cameras I've tried in the past)
Webcamoid is the only multiplatform solution I know, but on Windows I found it extremely unstable.

Hi, I would love this, but haven't found a way. I couldn't get webcamoid to work on my computer (Linux). Snap camera looks great but doesn't run on LInux?

The only other loopback solution I'm aware of is https://github.com/umlaeute/v4l2loopback .. but it only creates virtual devices, so you'd have to handle the capture (or any other way to stream to that device) yourself. Apparently you can use GStreamer for that https://github.com/umlaeute/v4l2loopback/wiki/GStreamer
(never tried though)
from hydra.
specifically the Desktop Capture As Producer section has the gst-launch to try. when creating a v4l2loopback device, you'll get a new /dev/videoX device (or 4). adjust the last pipeline element device=
parameter to point to that new device:
gst-launch-1.0 -v ximagesrc startx=1 starty=1 endx=320 endy=240 \
! videoconvert \
! "video/x-raw,format=YUY2" \
! v4l2sink device=/dev/video1
