You say you want to "extract audio from them (mp3 or ogg)". The last param is the name of the output file. The third option i.e -ab 192000 tells ffmpeg that we want the output to be encoded at 192Kbps and -vn tells ffmpeg that we dont want video. The second option -f mp3 tells ffmpeg that the ouput is in mp3 format. The -i option in the above command is simple: it is the path to the input file. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options.Ffmpeg -i video.mp4 -f mp3 -ab 192000 -vn music.mp3 For output streams it is set by default to the number of input audio channels. -ac - Set the number of audio channels.For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. For output streams it is set by default to the frequency of the corresponding input stream. -ar - Set the audio sampling f requency.-vn - Disable video, to make sure no video (including album cover image) is included if the source would be a video file.You can adjust that argument beside some others: type f -iname "*.webm" -exec bash -c 'FILE="$1" ffmpeg -i "$' \ įor e.g.
No one seems to use find, which let you do everything on one line. I guess that the mp3 codec isn't installed.
