I don't think that is necessarily true of all drivers, but see below.

As previous patch, use ff_get_video_buffer().

I don't like the name of this one - the miscellaneous-other-stuff filter...

Given that the (i965?) driver doesn't support combining the parts of this, would it be sensible to just make separate filters for them?  I think the code can be mostly in common, by defining two different filters in this file.
