Both. The plane size should have 16 + stride_align bytes padding added at the
end for some SIMD optimized functions to work, from the links I've posted
above.

The plane start offset must then be aligned otherwise some SIMD instructions
will trigger a general protection error.

The simplest way to work around this would be to increase the
align.padding_bottom value by 1 in gstavviddec.c. This would alloc one more
line than necessary in each plane.
