  • 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.

  • How can I split an mp4 video with ffmpeg every time the volume is zero ?

    14 mars 2019, par Juan Pablo Fernandez

    I need to split a video into many smaller videos.
    I have tried PySceneDetect and its 2 scene detection methods don’t fit my need.

    The idea is to trigger a scene cut/break every time the volume is very low, every time audio level is less than a given parameter. I think overall RMS dB volume level is what I mean.

    The purpose is to split an mp4 video into many short videos, each smaller video with short dialog phrases.

    So far I have a command to get the overall RMS audio volume level.

    ffprobe -f lavfi -i amovie=01x01TheStrongestMan.mp4,astats=metadata=1:reset=1 -show_entries frame=pkt_pts_time:frame_tags=lavfi.astats.Overall.RMS_level,lavfi.astats.1.RMS_level,lavfi.astats.2.RMS_level -of csv=p=0

    How can I get only the minimum values for RMS level and its corresponding frame or time ?

    And then how can I use ffmpeg to split the video in many videos on every frame that corresponds to a minimum RMS ?

    Thanks.

  • Ffmpeg- Split the video into 30 seconds chunks in android [duplicate]

    23 novembre 2019, par Corgi Mogi

    This question is an exact duplicate of :

    I am trying to split a video file into 30 second blocks.
    I do not need to specify where the 30 seconds start or finish.
    EXAMPLE- A single 45 second video will be split into VID1_part1 (30 seconds), VID1_part2 (15 seconds).

    Right now I am using the Ffmpeg command where I need to specify the starting and ending point.

    String[] complexCommand = {"-ss", "" + startMs / 1000, "-y", "-i", yourRealPath, "-t", "" + (endMs - startMs) / 1000,"-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", filePath};

    I also tried to add a for loop in order to repeat the process

     int start, end;
    
        for (int i = 0; i <= duration; i = i + 30) {
    
            start = i;
    
            end = start + 30;
    

    
            String[] complexCommand = {"-ss", "" + start, "-y", "-i", yourRealPath, "-t", "" + end,"-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", filePath};
    
            execFFmpegBinary(complexCommand);
    
        }

    But didn’t workout

    This works fine.
    But I want the command through I can split a single video into 30 second chunks.
    And should I use a single command for this purpose or a series of commands ?
    Help is much appreciated

    Previously split was made in wrong (half of original) position.
