| | | | | | | | | | | | | | | | | | | | | | | | | | The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms.

| | | | | | | | | | | | | | | | | | | | | | | | This macro is only used in two places, both in libavcodec, so this is a more sensible place for it.
