In various implementations, these techniques include relaxing the requirement that a file include only en. ) one EOB NAL unit. These techniques further include providing the EOB NAL unit from the highest layer when reconstructing the ,7 1 1 . 9 bitstream. This EOB NAL unit can be added to a last access unit in the reconstructed bitstream. When the EOB NAL unit from the highest layer is not present, an EOB NAL unit from a lower layer can be provided instead.
