  • Multilang : améliorer l’interface pour les blocs multilingues

    18 February 2011, by

    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.

  • Create time lapse video from other video

    17 December 2023, by Orlando

    Using avconv (or even ffmpeg, so I can use as a reference), how can I create a time lapse video by taking only anchor/reference frames from another video? Most information I find is on how to create a time lapse video by combining images, and I'd like to do it by extracting frames from a video. Say, if a video is 30 seconds long at 30 FPS, I'd like to take 60 out of those 900 frames (900/60 = every 15 seconds) to produce a 2 second video.

    


  • Rendering list of images over a video with ffmpeg does not work if video has audio

    12 May 2023, by Alex Stirken

    I'm using FFmpegKit for Flutter to render a list of changing images onto a video.
Im using the following arguments:

    


    final arguments = [
  '-y',
  '-i', inputVideoPath,
  '-framerate', '$fps',
  '-start_number', '100',
  '-i', '${tempDirectoryPath}/%3d.png',
  '-filter_complex', '[1:v]scale=720:1280 [ovrl]; [0:v][ovrl]overlay=0:0,format=yuv420p[v]',
  '-map', '[v]',
  '-c:v', 'libx264',
  "-preset", "medium",
  '-pix_fmt', 'yuv420p',
  '-shortest',
  '$outputFilePath'
];


    


    It works like a charm as long as the video file (.mp4) has no audio stream. If the video has an audio stream, only the first image is getting rendered (overlayed) over the video.

    


    Any suggestions?

    


  • Best video format for video processing and converting to mp4

    29 August 2014, by Max Grigoriev

    I may have video in selected format and I should make some video changes - add logo to the whole video as example and then convert to mp4. Right now original file is in h.264/mp4 format too. As I understand to add logo original file should be decoded to frames then logo should be added and then frames should be encoded to H.264 and packed to mp4. Since I’m newbie in video processing maybe there’s a raw video format which removes decoding stage and it saves time and cpu?

    Thanks
