  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • LibVLC DXVA2 Windows C++ Hardware Acceleration

    15 novembre 2016, par Sergiu Vlad

    I want to decode a h264 RTSP stream using DXVA2 Accelerated decoder. In VLC it does work but in my code have the following output :

    avcodec generic warning: threaded frame decoding is not compatible with DXVA2, disabled
    
avcodec generic debug: available hardware decoder output format 61 (dxva2_vld)
    
avcodec generic debug: available hardware decoder output format 128 (d3d11va_vld)
    
avcodec generic debug: available software decoder output format 12 (yuvj420p)
    
core generic debug: looking for hw decoder module matching "any": 1 candidates
    
core generic debug: no hw decoder modules matched

    Is this a problem with NV12 conversion ? Is there a way to force DXVA2 ?

    Thanks

  • Extracting audio from video using Xuggler

    13 février 2014, par Sudh

    I am trying to extract audio(mp3) from a video file (flv), but I keep getting Exceptions :

    05:02:10.326 [AWT-EventQueue-0] ERROR org.ffmpeg - [aac @ 000000000043B3F0] channel element 0.0 is not allocated
    java.lang.IllegalArgumentException : stream[0] is not video

    I tried with this :

    public void runExample(int a) {
    
    String sourceUrl="F:\\Software\\library\\test1.mp4";
    
    String destUrl="F:\\Software\\library\\test1.flv";
    
    IMediaReader reader = null; 
    
    IMediaWriter writer = null; 
    
    try { 
    
        reader = ToolFactory.makeReader(sourceUrl); 
    
        writer = ToolFactory.makeWriter(destUrl, reader); 
    
        reader.addListener(writer); 
    
        int sampleRate = 44100;
    
        int channels = 1;
    
        //writer.addAudioStream(0, 0, ICodec.ID.CODEC_ID_MP3, channels, sampleRate);
    

    
        while (reader.readPacket() == null) ; 
    
        //Should IMediaReader automatically call close(), only if ERROR_EOF (End of File) is returned from readPacket().
    
        reader.setCloseOnEofOnly(false); 
    
        //If false the media data will be left in the order in which it is presented to the IMediaWriter.
    
        //If true IMediaWriter will buffer media data in time stamp order, and only write out data when it has at least one same time or later packet from all streams.
    
        writer.setForceInterleave(false);
    
        System.out.println("closed...");
    
    } catch (Exception ex) { 
    
        ex.printStackTrace(); 
    
    }
    
}

    Also When I try this :

    public String seperateAudioStream(String pathToAudioFile)
    
    { String sourceUrl="F:\\Software\\library\\test1.mp4";
    
        String destUrl="F:\\Software\\library\\test1.mp3";
    

    
        IMediaReader reader = ToolFactory.makeReader(sourceUrl);
    
        reader.open();
    
        IMediaWriter writer = ToolFactory.makeWriter(destUrl,reader);
    
        reader.addListener(writer);
    
        int sampleRate = 44100;
    
        int channels = 1;
    
        writer.addVideoStream(0, 0, ICodec.ID.CODEC_ID_MP3, channels, sampleRate);
    

    
        while (reader.readPacket() == null);
    
        return null;
    
        IContainer container = IContainer.make();
    
        int result = container.open(sourceUrl, IContainer.Type.READ, null);
    
         // check if the operation was successful
    
          if (result&lt;0)
    
              throw new RuntimeException("Failed to open media file");
    

    
          int numStreams = container.getNumStreams();
    

    
          int audioStreamId = -1;
    

    
          IContainer writer = IContainer.make();
    
          writer.open(destUrl, IContainer.Type.WRITE, IContainerFormat.make());
    

    

    

    
          for (int i=0; i= 0){
    

    
                          if(packet.getStreamIndex() == audioStreamId)
    
                          {
    
                              if(coder.isOpen()){
    

    
                                  System.out.println("Writing audio ...");
    
                                  writer.writePacket(packet);
    

    
                              } else {throw new RuntimeException("Could not open Coder"); }
    
                          }
    
                      }
    
                  }else {throw new RuntimeException("Header not Written for writer container.");}
    
              }
    

    
              coder.close();
    
              audioCoder.close();
    
          }
    
          writer.writeTrailer();
    
          writer.close();
    
        return null;
    

    
   }

    I get error : ERROR org.ffmpeg channel element 0.0 is not allocated multiple times

    The documentation is unclear to say the least.. xuggler's website looks sick and none of the videos given in tutorial play... even on stack overflow most of the questions related to this are unanswered.

  • FFMPEG library's some command not working on android

    21 février 2014, par Saurabh Prajapati

    I need following 2 commands to work on android platform. I found many article on this site where they inform these command works fine for them but it is not working at my end

    For Fedding Effect :
    "ffmpeg -i filename1 fade=in:5:8 output.mp4"

    For Concate Video Files :
    "ffmpeg -i concat : filename1|filename2 -codec copy output.mp4"

    Error : App throws error like unknown command "concate" and "fad-in5:8".

    My Goal : I need to concate 2 "mp4" video files on android platform with Fed In/Fed Out effects.

    Following is my code
