Why not just avoid VLAs altogether (I don't like using features that are optional in modern standards)? All one needs to calculate a suitable offset is the alignment of AVBoundingBox. This can be done via _Alignof for C11 compilers and via compiler extensions for lots of other compilers (e.g. GCC supports __alignof__ since at least 3.1). And a generic alignment of (say) 8 can be used as a fallback.
