  • Que fait exactement ce script ?

    18 janvier 2011, par

    Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
    Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
    Installation de dépendances de MediaSPIP
    Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
    Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...)

  • 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.

  • Generating video from images and audio by FFmpeg

    24 mars 2020, par Cody

    I am new to FFmpeg and video/audio encoding. I try to use Fluent ffmpeg to generate a MP4 video from images and audio.

    There are 2 inputs only :

    If the audio duration is longer video length, just discard the excessive part of audio at the end.
    And all the images have to be shown in same duration.(i.e. The video should be in n/d FPS for n images and video with d second)

    Since the image input are not in number sequence, I use concat demuxer as input :

            let VIDEO_DURATION = 8;
    
        let ffmpeg = await FfmpegUtil.createCommand();
    
        let imageFiles: string[] = ["foo.jpg", "bar.jpg", ...]; //assume there are 67 image files
    
        let demuxerFile = await FfmpegUtil.createConcatDemuxerFile(imageFiles);
    
        let audioFile: string = "path/to/audio.wav";
    

    
        ffmpeg.input(demuxerFile)
    
            .inputOption(
    
                "-f", "concat",
    
                "-safe", "0",
    
            )
    
            .input(audioFile)
    
            .outputOption(
    
                "-r", `${imageFiles.length}/${VIDEO_DURATION}`,
    
            )
    
            .duration(VIDEO_DURATION)
    
            .save("path/to/output.mp4")
    
        ;

    it will spawn a ffmpeg command :

    ffmpeg 
    
    -f concat 
    
    -safe 0 
    
    -i path/to/demuxerFile.txt 
    
    -i path/to/audio.wav 
    
    -y 
    
    -r 67/8
    
    -t 8 
    
    path/to/output.mp4

    However the output file cannot be played.

    I also tried "-framerate", ${imageFiles.length}/${VIDEO_DURATION} in .outputOption(), it still output a file cannot be played and I found the frame rate always be 25 in its file property.

    Update 1 (added spawned command & ffmpeg console log) :

    spawned ffmpeg command & console log ("-r", `${imageFiles.length}/${VIDEO_DURATION}` as outputOption) :

    ffmpeg -f concat -safe 0 -i path/to/demuxerFile.txt -i path/to/audio.wav -y -r 67/8 -t 8 path/to/output_r.mp4

  • Using ffmpeg to read mp4 file from stdin and extract image is failing with "Invalid data found when processing input"

    16 mars 2023, par jsindos

    Using ffmpeg, I'm trying to read an mp4 file from stdin, and save the last frame of the file to jpg.

    


    cat PXL_20221118_051057924.TS.mp4 | ffmpeg -sseof -3 -i - -f mp4 -update 1 -q:v 1 last.jpg


    


    The command works fine when not running from stdin.

    


    When running from stdin, an empty file is created, with the following error message :

    


    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fcb4d0041c0] stream 1, offset 0x2eaee0d: partial file
pipe:: Invalid data found when processing input


    


    I've posted the full output below.
