Comment (by Guy Sivey):

 Replying to [comment:7 Balling]:
 > Ffmpeg does not support iTunSMPB tag

 Thanks for that information, Balling. I don't understand all of what you
 said, but I understand that iTunes creates mp3/m4a files which are not
 fully supported by ffmpeg, which is a bit of a shock to me. I am guessing
 that ffmpeg supports some kind of industry standard for making
 mp3/m4a(aac) gapless work, and that it is Apple who is out of line. How
 can I identify if my files follow this standard, and is there a
 recommended encoder which will follow this standard? LAME for mp3, I
 guess, but what for aac?
 Regards,
 Marmite
