  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • ffmpeg lossless mp4 to image sequence conversion (and back to mp4 again) [closed]

    2 juin 2021, par Cinderella Costallas

    I've browsed google for hours now and cant find anything about this.
I'm really struggling to extract the frames of an mp4 to an image sequence without any quality loss.
I need to be able to convert the image sequence back to an mp4 again also with no quality loss.
My purpose for this is to essentially drop half of all frames, making a 60fps mp4 into 30fps.
Previously the only other way I've found of doing this was to create a rawbitstream which takes up an absurd amount of disk space, and I don't want that. You can find that post here. Anything that can help me achieve this, I would greatly appreciate if you could share it.

    


  • node-fluent-ffmpeg editing video start time when merging

    3 mars 2018, par DarkArtistry

    I am trying to understand if this is valid, to add in the setStartTime option half way through merging my audio :

    new FFmpeg({ source: '/path/to/part1.avi' })
    
    .setStartTime(120)
    
    .mergeAdd('/path/to/part2.avi')
    
    .mergeAdd('/path/to/part2.avi')
    
    .on('error', function(err) {
    
        console.log('An error occurred: ' + err.message);
    
    })
    
    .on('end', function() {
    
        console.log('Merging finished !');
    
    })
    
    .mergeToFile('/path/to/merged.avi', '/path/to/tempDir');

  • Reduce bitrate of video with ffmpeg

    4 janvier 2021, par Z.Chorlev

    I'm using ffmpeg to check the bitrate of given videos and my goal is to reduce it to half of the original bitrate.

    


    For test purpose I executed this command

    


    ffmpeg -i example.avi


    


    and I saw that the bitrate of the videos was around 1030 kb/s

    


    I want to know which is the unit that ffmpeg uses for bitrate.

    


    ffmpeg -i example.aviffmpeg -b 515 new_video.avi


    


    I used b:a and b:v for audio and video, but the result is not correct again
I tried with just 515 and 515k, but still not correct ...

    


    My goal is to have output video with 515 kb/s bitrate.
