  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Compiling FFmpeg : libx264 not found

    17 mars 2016, par SaidTagnit

    I hope some one helps me the solve this problems. I was trying to compile FFmpeg 2.2.3 library under ubuntu 12.04LTS for android using android ndk r10e by following this tutorials :

    Tutorial1

    here is my build_android.sh file :

    when i execute buid_android.sh script without —enable-libx264 \ line everything is going well and i can get .a files on android/arm/ folder. but with this line it fails and show the following error in the console :

    ERROR : libx264 not found

    If you think configure made a mistake, make sure you are using the
    latest version from Git. If the latest version fails, report the
    problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on
    irc.freenode.net. Include the log file "config.log" produced by
    configure as this will help

    it seems like it can’t find where the libraries are, as i get a lot of the following errors in config.log file :

  • java bufferedimage array data immediately changes

                File outputfile = new File(fileLocation + "GrayScaledImage" + i + ".jpg");

        }//END for
    

    
                return totFrames;
    

    
    }//END METHOD long getFrameCount()

    Hope someone can explain this to me...
    I am just learning java so here goes...
    I wrote this code to count the number of frames in a .mov file and to test my buffered image array I generated files of the images. As the code is, it works as planned... The problem is immediately after the capturing, if I send the bufferedimages out as files, they all seem to be just the first image. see example below...

        for(int i = 0 ; i < frameNums  ; i++) 
    
        {
    
            try 
    
            {                   
    
                frameArray[i]= grab.grab().getBufferedImage();
    
                totFrames = i;  
    
                File outputfile = new File(fileLocation + "GrayScaledImage" + i + ".jpg");
    
                ImageIO.write(frameArray[i], "jpg", outputfile);
    
            } 
    
            catch (Exception e) {   /*e.printStackTrace();*/    }
    
        }//END for

    And now if I change that to...

        for(int i = 0 ; i < frameNums  ; i++) 
    
        {
    
            try 
    
            {                   
    
                frameArray[i]= grab.grab().getBufferedImage();
    
                totFrames = i;  catch (Exception e) {   /*e.printStackTrace();*/    }}
    
    for(int j = 0; j < frameNums; j++)
    
    {
    
    File outputfile = new File(fileLocation + "GrayScaledImage" + j + ".jpg");
    
                ImageIO.write(frameArray[j], "jpg", outputfile);
    
    }

    I don’t understand why I am getting the same image repeatedly.
    If further information Is required, just lemme know, this is my first programming question online... Usually find what I am looking for that others have asked. Couldn’t find this one.
    Thanks for your time
