How to extract aac audio from an mp4 file to m4a
How can I extract the aac audio from an mp4 file?
I tried with ffmpeg and -acodec copy but if i use mp4 as output it will still encode the video and I get the same file size.
If I use m4a as output it will somehow still encode the video and I get almost the same filesize.
With aac as output I can't open the file in puddletag although the file size suggests the video was stripped
Thanks in advance

I finally found the solution myself in using mp4 or m4a as output format and adding -vn to prevent also copying the video.
ffmpeg -i input.mp4 -vn -c:a copy output.m4a
(Source: https://superuser.com/a/706622/180675)
Seems simple now :]
Fast and lossless stripping

Just for fun, you can also do it by using vlc. The script below strips all *.mp4 files in the current directory to *.m4a. There are some error messages which can be ignored.
#!/bin/bash
quote="
executable="/usr/bin/vlc"
argument3=vlc://quit
#parameters
accessvalue=file
muxvalue=mp4
for x in *.mp4; do
inputname="${x}"
strippedname=${x%.mp4}
outputname=${strippedname}.m4a
quote_outputname=${quote}./${outputname}${quote}
echo ${inputname}
echo ${quote_outputname}
qtranscode=#transcode{vcodec=none}: # rm this commnt, cont' nxt line !!
standard{access=$accessvalue,mux=$muxvalue,dst=${quote_outputname}}
argument1="$inputname"
argument2=--sout=$qtranscode
"$executable" -I dummy "$argument1" "$argument2" "$argument3"
