  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • use java-ffmpeg wrapper, or simply use java runtime to execute ffmpeg ?

    12 mars 2017, par user156153

    I’m pretty new to Java, need to write a program that listen to video conversion instructions and convert the video once an new instruction arrives (instructions is stored in Amazon SQS, but it’s irrelevant to my question)

    I’m facing a choice, either use Java RunTime to exec ’ffmpeg’ conversion (like from command line), or I can use a ffmpeg wrapper written inJava http://fmj-sf.net/ffmpeg-java/getting_started.php

    I’d much prefer using Java Runtime to exec ffmpeg directly, and avoid using java-ffmpeg wrapper as I have to learn the library. so my question is are there any benefits using java-ffmpeg wrapper over exec ffmpeg directly using Runtime ? I don’t need ffmpeg to play videos, just convert videos

    Thanks

  • Building my JAVA parameter array for FFMPEG

    29 janvier 2016, par user3541092

    FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
    built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)

    Machine : Amazon Linux t2.micro (free tier)

    Sample File : sample_iTunes.mov
    Sample File URL : https://support.apple.com/en-us/HT201549

    I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().

    ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -y

    NOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().

        String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "
    
            + "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";
    
    String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);
    
    p = Runtime.getRuntime().exec(_ffmpegCommand);
    
    BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
    String _line = null;
    

    
    while((_line = _reader.readLine()) != null) {
    
        lw.writeLine(_logPath + _logName, _line);
    
        System.out.println(_line);
    
    }

    I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.

    The following string array works :

    try
    
        {
    
            String[] _params = {"ffmpeg",
    
                       "-i",
    
                       String.format("%s", _inputFile),
    
                       "-pix_fmt",
    
                       "yuv420p",
    
                       "-c:v",
    
                       "libx264",
    
                       String.format("%s", _outPutFile),
    
                       "-y"};
    

    
            p = Runtime.getRuntime().exec(_params);
    

    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    
        }
    
        catch (Exception e) {
    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    

    
        }

    However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :

    try
    
        {
    
            String[] _params = {"ffmpeg",
    
                       "-i",
    
                       String.format("%s", _inputFile),
    
                       "-pix_fmt",
    
                       "yuv420p",
    
                       "-c:v",
    
                       "libx264",
    
                       "-vtag", // <---- New
    
                       "mp42", // <---  New
    
                       String.format("%s", _outPutFile),
    
                       "-y"};
    

    
            p = Runtime.getRuntime().exec(_params);
    

    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    
        }
    
        catch (Exception e) {
    
            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    

    
            String _line = null;
    

    
            while((_line = _reader.readLine()) != null) {
    
                lw.writeLine(_logPath + _logName, _line);
    
                System.out.println(_line);
    
            }
    

    
        }

  • Carrierwave watermark a movie

    15 mai 2016, par Felix

    I’m uploading a movie with carrierwave to amazon S3. While uploading I want to watermark the movie.

    How can I do this ? How can I use stermio-ffmpeg while uploading ?

    I’m using a Rails application.
