FFmpeg's native aac encoder does not accept AV_SAMPLE_FMT_FLT as
input, it has to be AV_SAMPLE_FMT_FLTP (planar intead of packed).

Also note that this describes the current implementation, codecs may
(and have in the past) change their sample_fmts: You should always
check in your code and convert into the format the encoder needs.
