  • 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.

  • 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 :

    Any ideas how to make it work ?

  • How to encode a series of .dpx files using X264

    4 juin 2015, par user3759710

    I am complete newbie to video encoding. I am trying to encode a series of .dpx files into one single encoded video O/P file in any of the following format. ( .mp4,.avi,.h264,.mkv etc)

    I have tried 2 different approaches. The first one works and the second one does not.
    I would like to know the difference between the two. Any help / input would be much appreciated.

    1) using FFMPEG along with x264 library and it works well. I am able to produce desired output

    ffmpeg -start_number 0 -i frame%4d.dpx -pix_fmt yuv420p -c:v libx264 -crf 28
    -profile:v baseline fromdpx.h264

    2) I first try to concatenate all the dpx files into a single file using concate protocol in ffmpeg and then use x264 to encode the concatenated file.
    Here I see that the size of the concatenated file is the sum of all the files concatenated. But when I use x264 command to encode the concatenated file, I get a green screen (basically not the desired output) .

    ffmpeg -i "concat:frame0.dpx|frame01.dpx|frame2.dpx etc" -c copy output.dpx

    then

    x264 --crf 28 --profile baseline -o encoded.mp4 --input-res 1920x1080 --demuxer raw
    output.dpx

    I also tried to encoded the concatenated file using ffmpeg as follows

    ffmpeg -i output.dpx -pix_fmt yuv420p -c:v libx264 -crf 28 -profile:v baseline fromdpx.h264

    This also gives me a blank video.

    Could someone please point out to me what is going on here ? Why does the first method work and the second does not ?

    Thank you.
