• exec() just run when i access target php in browser

  28 septembre 2016, par Mohammad Shojaa

  i use this code to run another php for some work (ffmpeg convert)

      $binpath = get_option('binpath','/usr/bin/php');
  
      $command = $binpath." -cli -f ".ABSPATH."/videocron.php";
  
      exec( "$command > /dev/null &", $arrOutput );

  but when i upload a video and run this code don’t convert video for ever.

  but when i access to videocron.php from browser all videos i uploaded convert suddenly !!!

  i use alternative exec function(system(); exec(); passthru(); shell_exec();)
  and i check videocron.php by readable function, it is readable.

  even i change owner videocron.php to nobody user

  in mod_security log i get this error :

  [Tue Sep 20 23:01:11 2016] [error] [client 37.156.10.171] ModSecurity: Multipart parsing error (init): Multipart: Boundary not found in C-T. [hostname "codenevis.net"] [uri "/lib/upload-ffmpeg.php"] [unique_id "V@GAb38AAAEAAGrk2QoAAAAH"]

  but even i unistalll mod_security it don’t work automatically.

  but in all don’t convert video until i access to videocron.php from browser !

• ffmpeg WAV to MP3 Conversion - Audio Distortion and Timestamp Troubles

  24 septembre 2016, par user27547

  I’m using this command to convert a wav to mp3 :

  ffmpeg -i in.wav -ab 64k out.mp3

  The resulting mp3 has audio distortions, most notably a slight stuttering every few seconds.

  Also, the times no longer match. If I seek to the end of the file, then skip back 10 seconds, I’m able to hear the last 10 seconds of the file. However, if I go back a further 10 seconds, it jumps to several minutes before the end. I can then skip forward past the supposed end time (e.g. 13:44:08/13:43:57). I figure that this means the estimated time is different than the actual time, but it’s encoded at a constant bit rate, so I can’t imagine why it’s having this problem.

  I would appreciate any input on how to correct these problems. Thank you.
