Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
Complex classes like getid3_quicktime often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use getid3_quicktime, and based on these observations, apply Extract Interface, too.

||
| 1586 | Because the language codes specified by ISO 639-2/T are three characters long, they must be packed to fit into a 16-bit field. |
||
| 1587 | The packing algorithm must map each of the three characters, which are always lowercase, into a 5-bit integer and then concatenate |
||
| 1588 | these integers into the least significant 15 bits of a 16-bit integer, leaving the 16-bit integer's most significant bit set to zero. |
||
| 1589 | |||
| 1590 | One algorithm for performing this packing is to treat each ISO character as a 16-bit integer. Subtract 0x60 from the first character |
||
| 1591 | and multiply by 2^10 (0x400), subtract 0x60 from the second character and multiply by 2^5 (0x20), subtract 0x60 from the third character, |
||
| 1592 | and add the three 16-bit values. This will result in a single 16-bit value with the three codes correctly packed into the 15 least |
||
| 1593 | significant bits and the most significant bit set to zero. |
