• How to new & delete AVPacket ?

  18 octobre 2020, par PatrickSCLin

  I'm working with a FFmpeg project right now, I have to store the data of AVPacket which from av_read_frame, and fill data to new AVPacket for following decoding.

  


  Here is my problem : when I try to new & free an AVPacket, memory leaks always happen.

  


  I am just doing a simple testing :

  


  for(;;) {
    AVPacket pkt;
    av_new_packet(&pkt, 1000);
    av_init_packet(&pkt);
    av_free_packet(&pkt);
}


  


  What am I doing wrong ?

  


• Get video duration from file location without using ffmpeg

  15 juin 2014, par user3508453

  function getDuration($file){
  
          if (file_exists($file)){
  
           ## open and read video file
  
          $handle = fopen($file, "r");
  
          ## read video file size
  
          $contents = fread($handle, filesize($file));
  
          fclose($handle);
  
          $make_hexa = hexdec(bin2hex(substr($contents,strlen($contents)-3)));
  
          if (strlen($contents) > $make_hexa){
  
          $pre_duration = hexdec(bin2hex(substr($contents,strlen($contents)-$make_hexa,3))) ;
  
          $post_duration = $pre_duration/1000;
  
          $timehours = $post_duration/3600;
  
          $timeminutes =($post_duration % 3600)/60;
  
          $timeseconds = ($post_duration % 3600) % 60;
  
          $timehours = explode(".", $timehours);
  
          $timeminutes = explode(".", $timeminutes);
  
          $timeseconds = explode(".", $timeseconds);
  
          $duration = $timehours[0]. ":" . $timeminutes[0]. ":" . $timeseconds[0];}
  
          return $duration;
  
          }
  
          else {
  
          return false;
  
          }
  
  }

  This code is working fine but for some files it shows variable $duration is undefined even if the file exists ! please help someone.
