  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.

  • how to add overlay at the end of video without knowing time duration of video file - ffmpeg

    13 décembre 2019, par Luka mikic

    I have a bunch of video files to which I add animated overlay at the beginning of video, but I would like to add it again at the end of it t-13 seconds. This is my bash script :

    do
    
   ffmpeg -i "${f}" -i /app/logo/lower.mov -i /app/logo/logo.png -filter_complex \
    
      "[0:v]scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:x=(1280-iw)/2:y=(720-ih)/2:color=black[bg0]; \
    
      [bg0][1:v]overlay=10:10[bg1]; \
    
      [bg1][2:v]overlay=10:10,drawtext=fontfile=/app/logo/Courier Prime.ttf:text=$(basename "${f}" | cut -f 1 -d '.'): \
    
      fontcolor=white:fontsize=25:x=256:y=h-th-130:alpha=1:enable='between(t,2,15)'" \
    
      -c:v libx264 -crf 21 -preset ultrafast "${f%.*}.mp4" -y
    
done

    Is there any way to do this ? I know how to extract the duration with FFProbe, but do not know how to add duration dynamically to a variable and then apply it to code I have.

  • How do i add multiple sound effects (mp3) to a video (mp4) at any given time in the video ? [closed]

    25 octobre 2023, par StudentProgrammer

    I am trying to automate my editing process. I have a video.mp4 with a given length, a folder with different sound-effects.mp3 and a list of timestamps = (t1, t2, t3...). I would like to be able to insert any sound-effect at any given time in the video. Furthermore a sound may last multiple seconds and overlap another sound. I've tried to visualize the concept with images.
enter image description here
enter image description here
Preferably this would be done in Python. However, I would be extremely happy if anyone took their time to help me out using any means of programming required.

    


    I have tried using Moviepy without much success as I am only able to add sound to the start of the video. Perhaps ffmpeg is the way to go.

    


  • Add a fixed size image on a video, regardless of the video width & height FFMPEG [duplicate]

    30 juillet 2017, par Rita

    This question already has an answer here :

    This is my code that that is use is following

    $info = pathinfo($file) ;
$out = "$info[’dirname’]/ss_$info[’basename’]" ;
exec("ffmpeg -i ’".$file."’ -i ’".SS_ROOT."".$ss->settings[’watermark_image’]."’ -filter_complex ’overlay=main_w-overlay_w-10:main_h-overlay_h-10’ ’".$out."’") ;

    that works very well, but it doesn’t keep the logo aspect ratio. I tried this code on two videos with different resolution and this is the result
