  • Video converted to FLV using FFMPEG gets 0 size

    11 novembre 2011, par Sudhir

    I'm trying to convert avi file to flv format using FFMPEG on server, but its giving me problems. On conversion, the file is converted to flv format but no data (0 kb size file). Tried debugging the code but could not. The FFMPEG is installed in CentOS, in path /usr/bin/ffmpeg, and i'm using following command for conversion :

    $srcFile = "/home/mydomain/public_html/demo/test/sample.avi" ;
$destFile = "/home/mydomain/public_html/demo/test/sample_again.flv" ;

    $ffmpegPath = "/usr/bin/ffmpeg" ;
    
$flvtool2Path = "/usr/local/bin/flvtool2" ;
    

    $command = $ffmpegPath . " -y -i " . $srcFile .  " -ar 32000 -ab 32000 -f flv -s 320x240 ".
    
$destFile . " | " . $flvtool2Path . " -U stdin " . $destFile ;
    

    exec($command, $output) ;
    
print_r($output) ;

    I tried doing :

    exec("which ffmpeg") ;

    And it gave me the path /usr/bin/ffmpeg, but get following error when i execute the code :

    Array (

    What could be the problem. Is this the problem of Flvtool2, if yes then what is it. Please suggest something

  • Ffmpeg Video Codec

    30 janvier 2012, par cilmaz

    I split video like this :

    ffmpeg -ss 00:15:00 -t 00:15:00 -i life.mp4 -acodec copy -vcodec copy life-2.mp4

    After the process i want to play splitted file on flash player (JW Player), it doesnt starts. It waits to download all af video and then start. But the source video (life.mp4) starts playing immediately. Why ?
