  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • How can I change an animation into .mp4 video in android ?

    15 août 2016, par littlebird

    Here is the problem. First I have some pictures and I have built an animation in ImageView so that pictures can fade in and fade out, with rotating, scaling...
    Question is how to save it (or how to change this animation into .mp4 or other format). I have searched this problem in SO, some say using ffmpeg, or javaCV, or jcodec. But all these way save images to video one frame by one frame, I don’t understand how to completely save the rotating, scaling during each fading in and fading out. Or is there any way else to do so ?
    Thanks in advance.

  • Converting a video and capturing a thumbnail through ffmpeg-php

    14 mai 2014, par HackerManiac

    Can anyone give a code on how do i upload and covert a video using ffmpeg.

    As thought currently i have only uploading system.

    vu.php

    define('UPLOAD','../../videos/');
    
    $fileName = time().$file['name']; 
    
    $target = UPLOAD.$fileName;
    

    
  if(move_uploaded_file($file['tmp_name'],$target)){                
    
      exec("ffmpeg -i ".UPLOAD." ".UPLOAD.$filename.".flv"); 
    
  }

    This pice of code block just uploads the video on video folder but does not converts it to .flv.
    I am not sure how to use ffmpeg.

    My diretory looks like this

    www[localhost]->videos[videos folder]
    
www[localhost]->pictures[pictures folder]
    
www[localhost]->resources[folder]->php[folder]->vu.php

    I also want to return a .jpg image of any frame of video through json by converting via ffmpeg and uploading it to pictures folder.

    return json_encode(array("thumbnail"=>$image_src));

  • avcodec/mpeg12dec : Don't adapt (last|next)_pic.linesize for field pics

    23 juin 2024, par Andreas Rheinhardt
    avcodec/mpeg12dec : Don't adapt (last|next)_pic.linesize for field pics

    These values are not read anywhere. Furthermore, since commit
    
fe6037fd04db8837dcdb9013f9c4ad4e7eb0592e the linesize values
    
of the MPVWorkPictures were wrong for subsequent fields
    
in a chain of B-pictures (as they are always doubled and no longer
    
based upon the frame-linesizes) which can eventually lead to overflow.
    

    Finally, it makes no real sense to ever double the linesize
    
of the reference pictures at all : Even when the current picture
    
is a field, it can still reference both fields of reference
    
pictures and therefore the linesize should allow to address
    
both fields (for the same reason, data is not offset for
    
reference pictures).
