extends AbstractID3v2FrameBody

4.6. MPEG location lookup table

To increase performance and accuracy of jumps within a MPEG [MPEG]

audio file, frames with time codes in different locations in the file
might be useful. This ID3v2 frame includes references that the
software can use to calculate positions in the file. After the frame
header follows a descriptor of how much the 'frame counter' should be
increased for every reference. If this value is two then the first

reference points out the second frame, the 2nd reference the 4th
frame, the 3rd reference the 6th frame etc. In a similar way the
'bytes between reference' and 'milliseconds between reference' points
out bytes and milliseconds respectively.

Each reference consists of two parts; a certain number of bits, as
defined in 'bits for bytes deviation', that describes the difference
between what is said in 'bytes between reference' and the reality and
a certain number of bits, as defined in 'bits for milliseconds
deviation', that describes the difference between what is said in

'milliseconds between reference' and the reality. The number of bits
in every reference, i.e. 'bits for bytes deviation'+'bits for
milliseconds deviation', must be a multiple of four. There may only
be one "MLLT" frame in each tag.

<Header for 'Location lookup table', ID: "MLLT">
MPEG frames between reference $xx xx
Bytes between reference $xx xx xx

Milliseconds between reference $xx xx xx
Bits for bytes deviation $xx
Bits for milliseconds dev. $xx

Then for every reference the following data is included;

Deviation in bytes %xxx....
Deviation in milliseconds %xxx....
