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
