This probing structure feels very fragile and possibly harmful (opening random
devices and poking them). It might be better to just force the user to supply
the right device path?

I cleaned it up on v4 but I dont think it can be done much differently:
the user needs to query the capabilities of every /dev/videoX node..
btw the same probing is already done in libavdevice/v4l2.c
