  • Support de tous types de médias

    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) (...)

  • ffmpeg - put video atop of second and center it while keeping aspect ratio

    25 août 2022, par artolini

    I'm trying to put 16:9 video atop of same blurred 1:1 video just like on the photos.
I'm looking a wise guy with ffmpeg knowledge to help me with think of about the command which will :

    


      

    1. rescale 16:9 (sharp video) accordingly to blurred one height (keeping the width automatically to ratio)

      2. 


    2. center the 16:9 (sharp video) to x position = (blurredVideoWidth / 2) - (sharpVideoWidth / 2)

      3. 


    


    My current comment looks like this :

    


    ffmpeg -y -i ${squareBlurredVideoUri} -i ${square169VideoUri} -filter_complex "[1:v]scale=620:-1[v2];[0:v][v2]overlay=0:0" -codec:a copy ${squareFinalVideoUri}

    


    As you can see scale is hardcoded to 620 which is wrong because we should rescale it accordingly to blurred video height.

    


    Overlay is set to 0:0 which places sharp video to x = 0 and y = 0 and should center it

    


    Thank you in advance.

    Is there a certain version of libwebp I need to be using ? Any help would be greatly appreciated.
