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). -justin
