This had better be secure. Almost every historical implementation of
id3v2 was full of vulns. That's why rather than supporting it in the
mplayer demuxer I specifically made it skip id3v2.
Id3v2 also has some stupid things like being able to store arbitrary
binary data that might emulate mpeg startcodes. They used to allow
(but not require) it to be escaped to prevent startcode emulation, but
now the escaping is deprecated... :(
I don't object to a working implementation. Just be sure you get it
