Despite that list, it actually works against much older devices. I've ran it with a T2i, for example, which is like three generations older than they officially support.

Thanks -- I've been really bummed that they left 6D Mk. 1 owners out in the cold on this one.

Does anyone know of a similar linux app that works over USB rather than HDMI?

I've been using gphoto2 and ffmpeg on linux to use my 6D MkII as a webcam. I did test it with my old old rebel XSI and it did work as well

here is the command

  sudo modprobe v4l2loopback exclusive_caps=1 max_buffers=2
  gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -an -threads 0 -r 24 -f v4l2 /dev/video2

I did wrap in a shell script to test if the module is already loaded.

Works on the 6D. Thank you!

I'm only getting ~4 fps, with substantial latency. Is that your experience?

Image quality on the first lens I had at hand (40mm f/2.8) blows my Logitech 920 away. Field of view on the 920 is equivalent to a ~26mm on full-frame.

Super excited to see if my slightly-broken EOS M will do the trick, too.

Awesome -- I'll have to give it a try :)!

I've been using a 6D mk.1 with the Windows version of the Canon Webcam Utility Beta for a couple weeks now. No issues with running it, so far.

6D Mk 1 works great with Canon Webcam Utility Beta on macOS! I'm using it now.

How do you download the app? They require a serial number.

Aha, nice tip. I have a 1DX I was hoping to try it out on, has stacks of ports but I didn’t understand why it was too old. I’ll give it a shot.

That’s great because I have a T2i with magic lantern. Will have to give it a try.
