Audio Codec: libfdk_aac (HE-AACv2) is better than libfaac
Hi Adrian,
I was hoping to have an option to use libfdk_aac (HE-AACv2) because it has better quality in lower bit rate thus making video file size smaller to save bandwidth and disk space.
why do I know this? because I usually encode videos using mediacoder and I have compared them already in every way.
Hoping to hear your thoughts on this

HE-AAC version 2
ffmpeg -i input.wav -c:a libfdk_aac -profile:a aac_he_v2 -b:a 32k output.m4a

You can already use libfdk_aac in the script. You can select it (if your ffmpeg was compiled with support fdk_aac) in admin -> video -> config -> conversion. I however do not use any profile for the aac encoder. fdk_aac is the best audio encoder for ffmpeg (as their wiki says).

Re: Audio Codec: libfdk_aac (HE-AACv2) is better than libfaac
I have successfully recompiled ffmpeg with libfdk_aac support ...
now Im getting a better audio at 16k bitrate while file size is reduced.
nothing beats 1 optimized video file across all platforms (mobile or desktop)
saves bandwidth and disk space
a practical solution to someone like me who doesn't like to spend much on server resource
