Comment (by Anatoliy):

 The difference only is between 1-frame chunks and non-1-frame chunks.
 1-frame chunks are special in this regard.
 Seems this is the field of undefined behavior (but I suspect it is very
 close to become defined, just need some improvement to handle the case
 (because for x264 there is no such a problem), so this should not be
 considered as a bug, but as a feature request though).
