I looked in video4linux.cxx. I found hints for various cameras and 
explanations of the meaning of the hints.

Now, assuming that I have to try more or less randomly (maybe starting 
with hints that regars video size), how do I say programs to follow the 
exact hint that I am including? Do programs automatically try all? Do I 
have to assign a particular name to the set of hints for my capture card?
Now I also assume that I have to recompile pwlib and gnomemeeting for 
every change I do to video4linux.cxx. Maybe I can add more than one tip 
(different named sets os hints) so I can compile it just once, can I?

Thanks.
