  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Pipe series of images from java application to ffmpeg subprocess

    20 juin 2014, par Marco

    I am looking for a way to stream series of images (jpegs) from java application into FFMpeg STDIN pipe.
    FFMpeg should process these images and create a video file as an output.

    FFMpeg is executed as sub process of java application with the following command "ffmpeg.exe -i pipe:0 out.avi"

    When i run "ffmpeg -i input.jpg out.avi" command in the console, i get the "out.avi" file as expected

    But when i use the following tester code in my java application, i got an error.

    Code in Java application :

    File ffmpeg_output_msg = new File("ffmpeg_output_msg.txt");
    
ProcessBuilder pb = new ProcessBuilder(
    
        "ffmpeg.exe","-i","pipe:0","out.avi");
    
pb.redirectErrorStream(true);
    
pb.redirectOutput(ffmpeg_output_msg);
    
pb.redirectInput(ProcessBuilder.Redirect.PIPE);
    
Process p = pb.start();
    
OutputStream ffmpegInput = p.getOutputStream();
    

    
byte[] image;
    
File file = new File("input.jpg");
    
image = new byte[(int)file.length()];
    

    
FileInputStream fileInputStream = new FileInputStream(file);
    
fileInputStream.read(image);
    

    
ImageInputStream iis = ImageIO.createImageInputStream(
    
        new ByteArrayInputStream(image));
    
BufferedImage img = ImageIO.read(iis);
    

    
ImageIO.write(img, "JPEG", ffmpegInput);

    FFMpeg output :

  • how to pass a audio file with powershell pipe [duplicate]

    9 février 2020, par mudssky

    I’m trying to convert flac file to aac use qaac cli.
    qaac cli default don’t support flac file,so i use ffmpeg to convert it to wav ,and use pipe pass it to qaac

    this command can be run successfully in cmd
    ffmpeg.exe  -i .\input.flac  -f wav -| qaac64.exe -

    but in powershell ,the pipe passed string object,so it doesnt’t work properly
    ffmpeg.exe  -i .\input.flac  -f wav -| get-member

    Q : what’s the correct way in powershell to pass a file ?

  • FFMPEG - How to pipe RMS_level and pts_time metadata without generating unwanted metadata

    6 février 2020, par Tovi Newman

    I am trying to find the loudest (highest rms_level) moment in an audio file, but I need to pipe the metadata rather than write to a file.

    I converted the answer found here : [https://superuser.com/questions/1183663/determining-audio-level-peaks-with-ffmpeg][1]

    By removing the write to file command and adding a pipe.
    Here’s what I’ve got.

    ffmpeg -i loudSoft.mp3 -af astats=metadata=1:reset=1,ametadata=print:key=lavfi.astats.Overall.RMS_level -f null - 2> result.txt

    The only problem is, now I’ve got a lot of unwanted metadata before and after the RMS_level and pts_time data as well as [Parsed_ametadata_1 @ 0x7f9d42c37500] being printed on each line. None of that was being written when I was writing to a file instead of piping. (all I need is the time and the rms.)

    Here is an abridged version of what I get when I write to file :

    frame:0    pts:0       pts_time:0
    
lavfi.astats.Overall.RMS_level=-inf
    
frame:1    pts:47      pts_time:0.00106576
