LGTM and tested. I made some minor fixups (remove vestigial reference to misc_vaapi filter in 5/7, merge the trivial 6 and 7 into 4 and 5 respectively, some cosmetics) and applied.
One slightly weird effect I observed in testing is that if you run the procamp filter without any arguments (that is, with no nondefault h/s/c/b options) on the i965 driver then the output is green (YUV zeroes). The code looks kindof ok in that case (it provides a buffer containing zero filters), but maybe that's not allowed?
