There was an arbitrary limitation for a single device. I just removed
this, and opening two devices for left/right now works, at least with
the X11 grabber pseudo device (I don't have any v4l2 devices).

Can you test the latest version from the git repository?

It should be possible to open the video devices from the command line:
$ bino --device-frame-size=800x600 /dev/video0 /dev/video1

If this works for you, I'll change the GUI dialog to allow this, too.

Hm, we're going through FFmpeg to open v4l2 devices. What controls
would you like to adjust? Sorry, I don't know much about v4l2...
