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