I took a quick look and noticed the following (for the case it should go into cvs):

- If an ffmpeg decoder outputs floating point samples, they should be
   passed through and not converted to 16 bit int.

- The prime samples are completely ignored by the faad2 based decoder so ignoring them
   for the ffmpeg decoder would mean no feature regression.

- The proper method for getting the prime samples can be a separate patch. If the data
   is available in an itunes atom this can be used of course, but we shouln't write any
   itunes specific stuff unless the file type is LQT_FILE_M4A.
