But since we're putting the bytes into extradata and we're reading from it
again...can't we control the endianness here? I mean, since we're storing
them there, wouldn't the way we suppose they should be decoded be the right
way? I couldn't get the part about breaking remuxing...can you please expand
on it a bit more?
