How to encode specific metadata version in FFMPEG ?
11 février 2021, par Charlie BrittonI am batch converting lots of songs into shorter "Advert" songs for SHOUTcast and to be recognised as adverts by the server. The song must have
":Advert"
for both the title and the artist metadata tags. When I use the following command :


ffmpeg -i "$i" -c copy -vn -map_metadata -1 -metadata title=":Advert" -metadata artist=":Advert" -t 120 "adverts/ADVERT_$i"




I would expect it to output the song with only
":Advert"
as title and artist metadata but when I import it into the radio playout software (using ID3 1.x tagging) the metadata has not copied across and is therefore lost. Output from ffmpeg :

I believe this is happening because the tag names are different (e.g. title should be

Isolating/separating vocals from audio by FFMPEG
21 février 2023, par JonyI remove the vocals from music via


ffmpeg -i song.mp3 -af pan="stereo|c0=c0|c1=-1*c1" -ac 1 karaoke.mp3


The output is the music without vocals (not completely but fairly good).


I wonder what is the command to make the output separated vocals (vocal only) ?


I mean how to save the separated vocals in an audio file ?
