How to make MeGUI encode AAC with ffmpeg?

[wuemura]

I've downloaded all the MeGUI profiles but there are none for AAC encoding with ffmpeg. I would suggest this, maybe for a next version update since ffmpeg is a free tool and can handle this.

I use this command to make my AAC's with ffmpeg:
ffmpeg -vn -y -i scripts\01.avs -acodec aac -vol 586 -ac 2 -ar 44100 -ab 192k AUDIO01.M4A

I'm using this ffmpeg version:

The Nero AAC encoder can be used with megui and there are profiles for it. It is also free and likely higher quality than the ffmpeg aac encoder (FAAC?)

There is any paper, book, link, pdf that i can read about this differences in encoding quality between NERO AAC and ffmpeg AAC?

Thanks.

ffmpeg's AAC encoder is extremely experimental and still very buggy and beta (and worse than FAAC, let alone Nero).

Oh, I thought ffmpeg used FAAC. Didn't know they were working on their own encoder. Anyway from what is according to wikipedia the FAAC homepage:
Note that the quality of FAAC is not up to par with the currently best AAC encoders available.

Thank you Dark and nurbs for the information.
