I think the fact that src_stride2 is hardwired to 16
should be mentioned above the functions, should it
be called from someplace that doesn't know about
the restriction.

Doesn't H264 requires image_stride % 16 == 0 ? Because
if it can be assumed src_stride1 % 16 == 0, then the
vec_lvsl can be moved out of the loop.

(I don't think that src1/src2/dst are always properly
aligned ? that could solve the performance problem)
