    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • Bash : bash script to download trimmed mp3 from youtube url

    25 août 2017, par Bhishan Poudel

    I would like to download the initially x seconds trimmed mp3 from a video url of youtube.
    I found that youtube-dl can download the video from youtube to local machine. But, when I looked at the man pages of youtube-dl, I could not find any trim options.

    So I tried to use the ffmpeg to trim downloaded mp3 file.
    Instead of doing this is two steps, I like to write one bash script which does the same thing.
    My attempt is given below.

    However, I was stuck at one place :
    "HOW TO GET THE VARIABLE NAME OF OUTPUT MP3 FILE FROM YOUTUBE-DL ?"
    The script is given below :

    # trim initial x seconds of mp3 file
    
# e.g. mytrim https://www.youtube.com/watch?v=dD5RgCf1hrI 30
    
function mytrim() {
    
    youtube-dl --extract-audio --embed-thumbnail --audio-format mp3 -o "%(title)s.%(ext)s" $1
    
    ffmpeg -ss $2 -i $OUTPUT_MP3 -acodec copy -y temp.mp3
    
    mv temp.mp3 $OUTPUT_MP3
    
    }

    How to get the variable value $OUTPUT_MP3 ?
    echo "%(title)s.%(ext)s" gives the verbatim output, does not give the output filename.

    How could we make the script work ?

    The help will be appreciated.
