Re: [FFmpeg-user] Unknown encoder 'libfdk-aac'

[Alex Molon]

And in any case, even if compiled correctly, the encoder is called "libfdk_aac" 
with the underscore, not libfdk-aac

Cheers

libfdk is non-free, you have to compile FFmpeg yourself if you want
to use libfdk-aac.

what you have somewhere on disk is pointless when ffmpeg is not compiled 
to use it (as any other software out there) and to find out how it was 
built: ffmpeg -encoders


this will show you also typos and with "man grep" it should be easy to 
read -> "ffmpeg -encoders grep -i aac"
