    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • FFmpeg Android Video cropping speed and perfomance [duplicate]

    5 octobre 2016, par kishore jethava

    This question already has an answer here :

    FFmpeg 15 seconds video takes 15 seconds to crop.
    How can we reduce this cropping time with command or some other tricks ?

    I have refereed this question but didn’t helped.

    Here is code

    final FFmpeg ffmpeg = FFmpeg.getInstance(getActivity());
    
        try {
    
            ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
    

    
                @Override
    
                public void onStart() {}
    
                @Override
    
                public void onFailure() {}
    
                @Override
    
                public void onSuccess() {
    
                    Log.i(TAG, "FFMPEG Success ");
    
                    try {
    

    
                        /*Logic for cropping the original video to a square video depending of the                                           orientation of the original video*/
    

    
                        //Command for cropping square video
    
                        String[] cmd = {"-i", "path/source.mp4", "-vf", "scale=720:ih*720/iw, crop="720:720:0:0, "-preset","ultrafast","-strict","experimental","-vcodec","libx264","-preset","ultrafast","path/destination.mp4"};
    
                        // Execute cropping of video
    
                        ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
    

    
                            @Override
    
                            public void onStart() {
    

    
                            }
    

    
                            @Override
    
                            public void onProgress(String message) {
    
                                Log.i("Square", "progress : " +message);
    
                            }
    

    
                            @Override
    
                            public void onFailure(String message) {
    
                                Log.i("Square", "total fail : " + message);
    
                            }
    
                            @Override
    
                            public void onSuccess(String message) {
    
                                Log.i("Square", "Cropped video created.");
    

    
                            }
    
                            @Override
    
                            public void onFinish() {
    
                            }
    
                        });
    
                    } catch (FFmpegCommandAlreadyRunningException e) {
    
                        // Handle if FFmpeg is already running

  • How to combine 2 videos using either NReco ffmpeg ConvertMedia or just ffmpeg command line ?

    11 octobre 2016, par M. Ilchuk

    We have 2 videos : video1.webm and video2.webm.
    How to combine these two and get output.mp4 which contains video from video1.webm and audio from video1 and video2 ?

    Example :

    video1(audio1 in video1) + video2(audio2 in video2) = outputVideo(video1 + audio1 +audio2)

  • Installing libmp3lame to work with FFMPEG on raspberry pi

    13 octobre 2016, par Gloin

    I am using the moviepy module with python 3.2 on my RPi 2. It uses FFMPEG to read and write the video, so I installed FFMPEG using these instructions to the letter. Now when I run the program, it says that my video export failed because FFMPEG didn’t find the libmp3lame codec that it needs. How do I got about installing the libmp3lame codec onto my RPi 2 (running Raspian Wheezy) ?

    I think I have to reinstall FFMPEG to install the codec.. how do I do that correctly ?
