• PHP and FFMPEG advice/sollution for a unknown issue

  20 octobre 2015, par sonam Sharma

  I am having a live video streaming website and I allow people to upload all the video files to the site till now everything is ok.

  What I am doing is that I am using FFMPEG to convert the video to mp4 and also get a image out of the video after 20 seconds.

  The code that I am using is that :

   require 'vendor/autoload.php';
  
          $getEXT_check=substr(@$_FILES['profileimage99']['name'],-3);
  
          if($getEXT_check !='mp4' && $getEXT_check !='MP4'){
  
          exec('ffmpeg -i '.$uploadfile.' -f mp4 -s 896x504 '.$new_flv.''); }
  
          //execute ffmpeg and create thumb
  
          exec('ffmpeg  -i '.$uploadfile.' -ss 00:00:20 -vframes 1  '.$new_image_path);
  
          $theduration=exec('ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 '.$uploadfile.' 2>&1');
  
          $theduration_val=round($theduration/60, 2);

  What issue I am having is that

  1. sometimes the code dosent extract the image out of video
  2. video conversation takes very long time for non mp4 video (I am not converting mp4 videos)

  Some info what I have done on server. During the development of site I installed ffmpeg on my pc and downloaded the vendor directory by composer.json file. But I have not done these things on my server I have a dedicated server from bluehost and have ffmpeg installed at this location.

  /usr/local/bin/ffmpeg
  
  /usr/local/bin/mplayer
  
  /usr/local/bin/mencoder
  
  /usr/bin/flvtool2
  
  /usr/local/bin/MP4Box
  
  /usr/local/bin/yamdi

  During uploading the site what I did is that I also uploaded the vendor directory and all the files and made the site live. I haven’t used any of the path as given by my server admin after asking.

  Please suggest me something where I am doing wrong.

• ffmpeg taking time to convert video

  2 septembre 2015, par sonam Sharma

  hello all i am having a video hosting site like youtube where i allow almost all kinds of videos to be uploaded but i would like to convert all the uploaded videos to mp4 format

  i can do this and my code is below

    require 'vendor/autoload.php';
  
          $getEXT_check=substr(@$_FILES['profileimage99']['name'],-3);
  
          if($getEXT_check !='mp4' || $getEXT_check !='MP4'){
  
          exec('ffmpeg -i '.$uploadfile.' -f mp4 -s 896x504 '.$new_flv.''); }
  
          //execute ffmpeg and create thumb
  
          exec('ffmpeg  -i '.$uploadfile.' -ss 00:00:28.435 -vframes 1  '.$new_image_path);
  
          $theduration=exec('ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 '.$uploadfile.' 2>&1');
  
          $theduration_val=round($theduration/60, 2);

  this code converts the non mp4 videos to mp4 and gets a thumbnail and gets duration correctly but the problem is that the process takes very much time like more than 2-3 hrs if i upload flv or mkv formats of about 100mbs.

  please suggest me something better please if you need to see the full page code

  Complete Code :

       <?php
  
      @session_start();
  
     include "conn.php";
  
      include "date.php";
  
     $sid = $_SESSION['id'];
  
     $ipIP=$_SERVER['REMOTE_ADDR'];
  
     $uploaddir = "members/$sid/video/";
  
  
  
       //Check the file is of correct format.  
  
        function checkfile($input){

        $extfile = substr($input['name'],-4);

      $live_dir = "mem/$sid/video/";
  
    //$live_img is for the first frame thumbs.
  
      $live_img = "mem/$sid/img/";        
  
      $seed = rand(11111111111193,9999999999999929) * rand(3,9);
  
      $getEXT=substr(@$_FILES['profileimage99']['name'],-5);

      if($safe_file['safe'] == 1){
  
                  if (move_uploaded_file(@$_FILES['profileimage99']['tmp_name'], $uploadfile)) {
  
  
  
                  $base = basename($uploadfile, $safe_file['ext']);

      $dbentry_o=mysqli_query($conn,"insert into vids (uid,chid,ctid,vname,vdisc,duration,time,ip,src,thumb) values ('$sid','$channel','$catag','$titlename','$desc','$theduration_val','$date','$ipIP','$new_file','$new_image')");
  
      echo "<img src="http://stackoverflow.com/feeds/tag/mem/$sid/img/$new_image" class="The_Append_L_snap" style='max-width: 300px; max-height: 300px' />";die;
  
           } else {
  
                  echo "Possible file upload attack!\n";
  
                  print_r($_FILES);
  
           }
  
  
  
      }else{
  
  
  
           echo 'Invalid File Type Please Try Again. You file must be of type 
  
           .mpg, .wma, .mov, .flv, .mp4, .avi, .qt, .wmv, .rm'.$_FILES['profileimage99']['name'];
  
  
  
      }
  
    }else{
  
   echo 'Please choose a video';die;
  
    }
  
    ?>

  The issue :
  FFmpeg call above takes too much time to convert the video to MP4.

  Note :
  In the future I will be having a quality selector in my video.js player.

• Retrieve Creation Date and set as basetime in overlay ffmpeg

  27 janvier 2021, par oiluig

  I want to print time as overlay on a video, starting from the creation time of the video file.
I found this topic :
FFmpeg for marking time video based on a reference date

  


  I can also get the creation date with ffprobe :
ffprobe -v quiet -select_streams v:0  -show_entries stream_tags=creation_time -of-default=noprint_wrappers=1:nokey=1 video.mp4

  


  Is there a way to retrieve the metadata creation_time directly with ffmpeg ?
How set it as basetime ?
