  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.

  • FFMPEG - Stream discovered after head already parsed [on hold]

    7 février 2014, par John Doe

    I am trying to live transcode an RTMP stream to another RTMP HLS stream using the following command :

    ffmpeg -re -i rtmp://localhost/videochat/testing -c:v libx264 -c:a:0 libfaac -b:a:0 480k -f flv rtmp://localhost:12345/hls/mystream;

    However I receive the following error and the transcoding never begins :

  • Convert a video and capture a jpeg frame via ffmpeg php

    15 mai 2014, par HackerManiac

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

    As thought currently i have only uploading system.

    vu.php(only a part is shown)

    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));
