Parameters that describe how pixels are packed.
If the format has chroma components, they must be stored in comp[1] and comp[2].

Amount to shift the luma height right to find the chroma height.
For YV12 this is 1 for example. chroma_height= -((-luma_height) >> log2_chroma_h) The note above is needed to ensure rounding up. This value only refers to the chroma components.
