Being the one who wrote v4l2.c, I think I have to speak up :)
I'd like to propose a tradeoff solution: let's leave grab.c coexist with
v4l2.c for some time as a backup solution (or as the solution for those
who have not v4l2), removing it only after some time (6 months?).
About v4l maintainance: I think that if grab.c fails but v4l2.c works,
people should switch to v4l2 (so, in this case I see fixing grab.c as a
waste of time).
So, Flavio, can you test the current CVS, to see if the v4l2 input works
If it works, I think we can leave grab.c as it is.
If it does not, I'll look at fixing it, and I'll also have a look at
your grab.c patch and test it.
