Hi.
Good day!
My issue is I got an error when i used libfaac & fdkaac to encoding audio.wav with ffmpeg
my command for faac is
ffmpeg -i test.wav -f wav - | faac -w -q 170 -o f1.m4a
my command for fdkaac is
ffmpeg -i test.wav -vn -f wav - | fdkaac -if - -ignorelength --profile 2 --bitrate-mode 3 -o song.m4a
Regards.

use:
Code:ffmpeg -y -loglevel fatal -i "PATH TO INPUT" -acodec pcm_s16le -f wav - | ..
Cu Selur
Ps.: Also instead of making screenshots, simply copy the content of the command line window (right click, select all, right mouse click on the selected content, copies the content to the clipboard and 'ctrl+v can be used to paste it) and use 'code'-tags.users currently on my ignore list: deadrats, Stears555 -
hmm nothing happened, I got this message - faac

also I removed "y -loglevel fatal' just for test, I got the same error ^^" in the first topic
-y -loglevel fatal -i test.wav -acodec pcm_s16le -f wav - | fdkaac -o song.wav-y -loglevel fatal -i test.wav -acodec pcm_s16le -f wav - | faac -w -q 170 -o foo1.wav -

and the output extention of files created by aac encoders is not .wav

Thank you guys =D
I have one question, there's no different by using fdkaac or libfaac right ? -
There exists at least one difference between faac and the Fraunhofer AAC encoder.
This latter is more-efficient, id est, it needs less bitrate than faac for outputting the same quality.
But if storage space is not important for you, then there is no problem in encoding stereo sources at 256, 320 or 384 kbps with faac -
Thread would be better in our Audio Forum. Moving it.

thanx -
ffmpeg has a bunch of filters that might subjectively improve the image quality, read: https://www.ffmpeg.org/ffmpeg-all.html#Video-Filters personally I use Avisynth or Vapoursynth for filtering and rarely ffmpeg so no recommendation from me there. (+ giving advice on improving a whole movie from a single screenshot is a fools errant)
if you don't want to filter the content, simply use a lower crf value and/or a slower preset to archive a better quality retention.
(if you go for lossless encoding you won't lose quality, but the file size will increase a lot)users currently on my ignore list: deadrats, Stears555
