  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • 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

  • orangepi zero 2w, ubuntu, using a usb webcam ffmpeg to record videos, low FPS [closed]

    28 janvier, par Qingfu Shi

    I use a OrpangePi zero 2w, USB HIK 2K Cam, to record videos.
Ubuntu, ffmpeg installed,
the cmd

    


    ffmpeg -f v4l2 -video_size 1920x1080 -r 25 -input_format mjpeg -i /dev/video1 -vf "transpose=1" -c:v libx264 -preset fast -crf 23 output.mp4


    


    I want the fps to be at least 25, so it looks smooth, but I only got about 4.7 fps.

    but I want the video at least 1080p@30fps. What's the bottleneck ? is it possible to modify the cmd to achieve this ?
OrangePi zero 2w, use an AllWinner H618 cpu, with 1G RAM, 64G v10 sd-card.
