  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Using Java and ffmpeg to most efficiently merge mp3 audio file and jpeg image file to a video file [closed]

    25 juin 2020, par Eugen

    I'm looking for an efficient way in Java to merge a large .mp3 file and a single .jpg image to a video format for youtube. If I use :

    


    ffmpeg -loop 1 -i image.jpg -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest output.mp4


    


    the result is very slow, especially for large .mp3 files. Is it possible to do it more efficiently with ffmpeg ? I know there must be a way to do it much more efficiently, like all the online converters are doing it.

    


  • Inserting an image inside a video every few frames using ffmpeg

    31 juillet 2023, par Erez Hochman

    Can I use FFMPEG to insert an image every 20 frames in a video ? 
I'm trying to create a subliminal message experiment and I thought it would be an easy way to make it but I can't find anything online.

    



    I tried to make something myself and created a script that :
    
1.splits a file into audio and video files
    
2.splits the video into frames
    
3.overwrites every 20th image in the sequence with the message image
    
4.re-encoding the video
    
5.concatenating it with the original audio

    



    this works but it's way more disk space consuming to be comfortable, is there a better way to do this ?
    
any advice or thought would be happily welcome.
