Can I Convert MP4 to MP3 Using FFmpeg?
Absolutely! You can convert MP4 to MP3 using FFmpeg. Converting MP4 files to MP3 will allow you to save space in your computer since audio files are smaller than video files. Plus, sometimes you only need the audio and not the video itself that comes in MP4 format.
Part 1: How to Convert MP4 to MP3 Using FFmpeg
FFmpeg is a free software that can record, convert (decode/encode), and stream both video and audio. FFmpeg converts many formats into other formats. Basically it decodes the audio/video of one format to encode it into another. The “FF” in FFmpeg stand for fast forward and “mpeg” is a name for various video formats.
Steps to Convert MP4 to MP3 using FFmpeg:
First of all, you have to install FFmpeg in your PC.
a) Once downloaded, enter the following command (change the word 'file' with the name of your mp4 file):ffmpeg -i file.mp4 file.mp3
b) An alternative command that can also be used is:ffmpeg -i file.mp4 -q:a 0 -map a file.mp3
That’s it. Your file has now been converted from MP4 to MP3 in Ubuntu (Linux Operating System).
