[Libav-user] Converting PCM to AAC

[Oosman Saeed]

Thank you Carl. I will change it to FLTP and try it out. 
I am using mono sound, not stereo. Does it matter if its FLT or FLTP?
Thanks,
Oosman

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.
