  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.
    While using MediaSPIP, you are invited to avoid using words like "Brand", "Cloud" and "Market".
    MediaSPIP is designed to facilitate the sharing of creative media online, while allowing authors to retain complete control of their work.

  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • Android video crop using ffmpeg

    12 août 2016, par Pramod Patel

    I am using https://github.com/WritingMinds/ffmpeg-android-java for cropping a video using this command :

    execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out);

    where "in" is inputfile and "out" is outputfile.

    I went through a lot of same questions and couldn’t find required solution for this. I also tried the following command which i found going through the search :

    execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out);

    The main error that I’m getting here is : Output file #0 does not contain any stream

    private void execFFmpegCommand(final String command) {
    
    try {
    
        ffmpeg.execute(new String[]{command}, new ExecuteBinaryResponseHandler() {
    
            @Override
    
            public void onFailure(String s) {
    
                Log.d(TAG, "FAILED with output : " + s);
    
                progressDialog.dismiss();
    

    
            }
    

    
            @Override
    
            public void onSuccess(String s) {
    
                Log.d(TAG, "SUCCESS with output : " + s);
    
            }
    

    
            @Override
    
            public void onProgress(String s) {
    
                Log.d(TAG, "Started command : ffmpeg " + command);
    
                Log.d(TAG, "progress : " + s);
    
            }
    

    
            @Override
    
            public void onStart() {
    
                Log.d(TAG, "Started command : ffmpeg " + command);
    
                progressDialog.show();
    
            }
    

    
            @Override
    
            public void onFinish() {
    
                Log.d(TAG, "Finished command : ffmpeg " + command);
    
                progressDialog.dismiss();
    

    
            }
    
        });
    
    } catch (FFmpegCommandAlreadyRunningException e) {

  • Cannot convert from mts (AVCHD) to mkv using ffmpeg

    10 août 2016, par waran

    I was trying to convert a .MTS file from my camcorder (Panasonic HC-V700) to a .mkv file (because my editing software does not support MTS). I used the following command :

    ffmpeg -i 00000.MTS -scodec copy -acodec copy -vcodec copy -f matroska 00000.mkv

    But instead of getting a mkv file I get this :

    Any ideas why is it not working ? (I am on Kubuntu 16.04 and I have ffmpeg version 2.8.6-1ubuntu2.)

    (I’m sorry for my English.)

    Edit :

    I tried the command without the subtitle stream (ffmpeg -i 00000.MTS -c copy -sn 00000.mkv), conversion failed again :

    Edit : Temporary solution

    I have found out, that converting to mp4 (fmpeg -i 00000.MTS -c copy -sn 00000.mp4) works. This does not solve the issue, but I can use the mp4 format in my editing software as well.

  • How do I improve the quality of a video produced from still PNG images ?

    9 avril 2012, par cormullion

    I'm trying to create a video from a few hundred PNG images. The PNG images look OK to me, e.g. here are two in MacOS X Preview :

    two images

    They're about 1200 pixels square, 16 bit RGB, no transparency.

    But my attempt to make a few hundred of these into a video is encountering the following problem - nearly every frame has this yellow corruption (artefacts ?), that sort of blocky flickery stuff you see on poor quality videos :

    video still

    The ffmpeg command I'm using is something like this :

    ffmpeg -f image2 -i /tmp/image-%07d.png -vcodec mpeg4 -vb 20M -r 20 poincare.mov

    I've tried changing a few parameters, but I probably changed the wrong ones. Any idea which parameters I should be changing, and to what value ?

    Console output is :

     ffmpeg -f image2 -i /tmp/image-%07d.png -vcodec mpeg4 -vb 30M -r 30 poincare.mov
