  • 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

  • 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.
