You can also use the -acodec option to dictate what encoder you want to use such as AAC or whatever. Your command would then be: ffmpeg -i 2.webm -vn out.mp3 So for your example, the command to get an MP3 file that contains only the first audio stream from your input would be: ffmpeg -i 2.webm -map 0:a:0 out.mp3Īlternatively, you could tell ffmpeg to not include video streams using the -vn option but I like to be explicit. I'm not sure of fluent-ffmpeg, but using ffmpeg, you would use the -map option to dictate what streams you want from you inputs in your output. You could use the noVideo() method which tells ffmpeg to produce output with "no video".
