You can do this on Linux using gphoto2, ffmpeg, and v4l2loopback. You probably won't get full resolution but the quality will still be good enough for video conferencing. See here for a guide.
The problem is that Canon locks the higher resolution capabilities behind a paywall, and this particular solution is also low resolution. So it's not really a bypass for this, at least not in the current state.
Good point! For my use case (on a different brand, Sony) I'm fine with the lowered resolution since I just use it for video conferencing, in which case the raw resolution is limited anyway. But for users who need higher resolution, using an HDMI capture card might be better for a one time fee rather than a subscription.
Cheers! Thank you
