Thanks for your help. From bttv's website, I see that it is a Linux driver
for Bt848/849/878/879 based frame grabbers. What if I have a card that uses
a different chip? Does that mean I have to write a new driver? Do I have to
modify v4l as well?
Thanks for any help.
Regards,
Eric

take a look at:
http://planeta.terra.com.br/informatica/gleicon/video4linux/
I've put some documentation and examples at my website, regarding the v4l
api, including videodog, my app, and a example on gtk+v4l
