When converting an mp3 to m4a, id3v2 tags are automatically converted to id3v1 (lose additionnal fields, truncate titles).
Don't know if it's a bug related to MediaCoder or the used tools though.

ID3v2 tags lost on conversion
Re: ID3v2 tags lost on conversion
Yes only ID3v1 is added in output MP3.
When things work together, things work.

I have found out more about this bug, so if it may help...
When we convert an mp3 with only v2 tags everything is ok, but when the file contains both v1 and v2 tags, only v1 are kept.
