pMusic writes tags defined in the id3 protocol version 2.3. BUT, it stays close to version 1.1 of this standard.
The benefits of lending towards id3v1 compared to id3v2 are:
- that many file formats (ie. aac, ape, wma...) supports the same tags (tag-names) as used in id3v1, so the tagging-tool in pMusic can be straightforward. Including extra tags from the id3 version 2 protocol would heavily complicate both code and gui.
- that ffmpeg uses the same metadata code for these basic tags for different file-types, and it makes my tagging-code simple as well.
While pMusic reads id3 ver 1.1, it does not follow version 1.1 strictly when in comes to the writing the genre tag. pMusic writes the genre tag as a text-sting rather than a number (as in id3v1). This because text-string is common for other file-formats. Id3 verison 2 supports strings in the genre tag (as well as numbers).
