How to enumerate video devices?

How to enumerate video devices?

[Lars Hanisch]

Hi,

  What is the best method to enumerate video devices, so that a program 
can display a list of present hardware in/outputs? Just iterating over 
/dev/video0 to /dev/videoSomeHighNumber seems a bit 'unprofessional'.

  (BTW I'm also looking for the right way of enumerating framebuffer 
devices...)

  I didn't find anything in the api-spec nor at google (perhaps I had 
the wrong searchphrases?).

  Please enlighten me. ;-)

Lars.
