The most straightforward way to convert a video to MP3 is with the following FFmpeg command: ffmpeg -i input_video.mp4 output_audio.mp3. Here, -i stands for input, which tells FFmpeg to grab the file you want to convert, in this case input_video.mp4. The second part, output_audio.mp3, is the name you want to give your converted file.
