ffmpeg -i video.mp4 -vn audio.mp3
ffmpeg -i input.mp4 -vcodec libx265 -crf 28 output.mp4
For AAC format without any conversion:
ffmpeg -i movie.mp4 -vn -acodec copy output.aac
Compress mp3 file with variable bitrate
ffmpeg -i input.mp3 -q:a 4 output.mp3
q:a with 6 is also ok! I released my episode with that and size is better.
