Till now there has not been a standard vbi API for v4l. It seems now
that the v4l2 vbi API has been adopted for the 2.4 series kernels
though, so I assume that this will be in place soon. The v4l2 vbi spec
allows for multiple capturing opens, each open selecting only the vbi
lines that it needs.
Coincidentally, I started coding vbi support for bttv2 last night, and
hope to have it available early next week. (This will include the
multiple capturing opens stuff).
