• ffmpeg connection reset by peer

  8 mars 2015, par Quentin Spottiswoode

  I have a problem when using ffmpeg :

  quite often my clients will have slightly dodgy internet connections but they subscribe to a service which is designed to record a stream that they are hosting, and record it for hosting on something like a wordpress site.

  ffmpeg is called by a python script. I would like, ideally, to know if ffmpeg will throw an exception or return a value that can be accessed by the python script and used as a variable to determine if there was a problem recording the audio.

  at the moment python calls ffmpeg using :

  os.system('ffmpeg -i [stream address] -t 1:00 -acodec copy ')

  when I simulate a connection loss (turning off the NIC on the virtual machine) ffmpeg prints to the terminal

  Connection reset by peer

• What is wrong with this video produced with libx264 ?

  6 janvier 2015, par Natal

  I’ve been trying to get a c++ wrapper around libx264 (version 142) to work. I am able to produce a video with x264 with no errors during encoding. Most standard video players (QuickTime, VLC...) are NOT able to read it but don’t display any errors. However, mplayer is able to read it.

  I am not able to determine what is wrong with it (Corrupt header ? Corrupt data ?).

  The video is available here : https://www.dropbox.com/s/godnip85pezdi89/test_h264.mp4?dl=0

  The class wrapped around libx264 I use to encode the video is here : https://gist.github.com/anonymous/4eb46b838fcf84ed02aa

  Any help to identify what I’m doing wrong would be greatly appreciated.

  Thank you !

• How to setup ffmpeg for linux server

  1er décembre 2014, par hitesh

  I need to create a screen shot from video,

  I have followed this tutorial to do the intial setup in window 8, php 5.3

  1) I downloaded the ffmpeg from here -[
  http://ffmpeg.zeranoe.com/builds/ ] for 64 bit operating system.

  2) I followed the https://www.youtube.com/watch?v=gU49GiWGGAI , video and did all configuration successfully and phpinfo() shows that ffmpeg has been installed.

  3) Then I tried this to find out whether it is working or not,

  It worked successfully

  4) Next I followed this video tutorial here and thumbnails were created successfully.

  below is my code

  /**
  
   * FFMPEG-PHP Test Script
  
   *
  
   * Special thanks to http://www.sajithmr.me/ffmpeg-sample-code for this code example!
  
   * See the tutorial at http://myownhomeserver.com on how to install ffmpeg-php.

  error_reporting(1);
  
  error_reporting(E_ALL ^ E_NOTICE);
  
  // Check if the ffmpeg-php extension is loaded first
  
  extension_loaded('ffmpeg') or die('Error in loading ffmpeg');
  
  
  
  // Determine the full path for our video
  
  $vid = realpath('./videos/myvideo.mp4');
  
  $videosize = filesize($vid);
  
  $remoteVideo = 'http://video-js.zencoder.com/oceans-clip.mp4';
  
  
  
  //ffmpeg
  
  
  
  $ffmpeg = dirname(__FILE__) . "\\ffmpeg\\bin\\ffmpeg";
  
  $imageFile = "1.png";
  
  $image2 = "2.png";
  
  $size = "120x90";
  
  $getfromsecond = 7;
  
  $cmd = "$ffmpeg -i $vid -an -ss $getfromsecond -s $size $imageFile";
  
  $cmd2 = "$ffmpeg -i $remoteVideo -an -ss $getfromsecond -s $size $image2";
  
  if(!shell_exec($cmd)){
  
      echo "Thumbnail created";
  
  }else{
  
      echo "Error Creating thumbnail";
  
  }
  
  
  
  if(!shell_exec($cmd2)){
  
      echo "Thumbnail for remote url was created";
  
  }else{
  
      echo "Error Creating thumbnail for remote url ";
  
  }

  ---

    OUTPUT
  
      Thumbnail created
  
      Thumbnail for remote url was created

  Now above code works as expected in my local, in window machine , I need to do it in my server environment(Linux server) with php 5.5. How do I do the configuration for ffmpeg in linux server with php 5.5.
