The -i option in the above command is simple: it is the path to the input file. ffmpeg -i video.mp4 -f mp3 -ab 192000 -vn music.mp3. acodec copy says use the same audio stream that's already in there. ffmpeg -i input-video.avi -vn -acodec copy output-audio.aac. The post title comes from “Convertible” by The Wedding Present, or Theweddingpresent as they were presenting themselves in 1996 when they released Mini, featuring this track. ffmpeg -i input.mp3 -ss 0:01:00 -t 0:00:30 output.wav. The recursive conversion and artwork/metadata mapping works better than in Audacity, so I’ll be doing this from now on. Using it for other file types is also an improvement on my previous Audacity macro approach. /rebates/&.com252fvideo-cutting252fffmpeg-extract-audio-from-mp4. To extract the audio from a video: ffmpeg -i video.mp4 -vn audio.wav As you might have guessed, the -vn option will remove the video stream from the output, leaving only the audio. This workflow meant I could convert all of the opus files I had. The -an option will completely remove the audio from a video, and since were just copying the video codec as is, this most likely will only take seconds. Then go to Organize > Options > Rip Music > Select an output. It converts it using our parameters and names the output file by switching the extension for mp3. If you stick on this way, get an audio CD and burn the audio in your MP4 to it. Initially, an mp3 subdirectory is made, then ffmpeg receives the opus file via the quoted curly braces as an input. This one-liner will find (recursively) all. iname '*.opus' -exec bash -c 'D=$(dirname ".mp3"' \ Ĭredit to this StackOverflow answer.
