• ffmpeg after converting avi to mp4 need wait till video loads in flash player 100% otherwise video is buffering

  28 octobre 2013, par Xenos Trojanowicz

  So if fixed all issues with my ffmpeg journey now I just need that after converting videos they play in flash player instantly and no need to wait till video loeaded 100% I use :

  if ($success_msg) {
  
      $tmp_parts = explode('.', $file['name']);
  
      $ext = array_pop($tmp_parts);
  
      $ext = strtolower($ext);
  
      if($ext == "avi" && $convert_avi == true) {
  
          $convert_source = _VIDEOS_DIR_PATH.$new_name;
  
          $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
  
          $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
  
          $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libfaac -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
  
          echo exec($ffmpeg_command);
  
          $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
  
          $result = @mysql_query($sql);
  
          unlink($convert_source);
  
      }
  
      echo $success_msg;
  
  }

  To convert videos

• ffmpeg stream encoding out produce a stream shows different program on each start

  15 octobre 2018, par Ryan Philip

  I am using ffmpeg for almost one year, my stream recently started behaving badly.

  The lines on ffmpeg screen started running crazy fast when restreaming it, causing more CPU (with no encoding). I have mapped the stream to select only one stream. But the problem is even with mapping I am getting different program each time when it is played.

  Also each program it is playing for less than a minute. There is no specific error message showing on ffmpeg screen. Only the output is behaving badly.

  I even tried ffmpeg version 3.3, 3.4 and 4.0 with same results.

  It has so many resolution streams, so i selected only 33 (video) and 34 (audio), the ones with highest resolution.

  ffmpeg -i "http://insourceip/stream.m3u8" -err_detect explode  -c copy -map 0:33? -map 0:34?  -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 out/music.m3u8

  Please help me with this.

  Below is the output : the one after (No longer receiving playlist 8) start running crazy when started.

• Is there a way a video can be encoded on its own when uploaded into server

  18 février 2013, par user1914374

  Below is my code where it uploads a file into a server and stores the names of each uploaded file into the db :

  <?php
  
  
  
   // connect to the database
  
   include('connect.php');
  
  
  
    /* check connection */
  
    if (mysqli_connect_errno()) {
  
      printf("Connect failed: %s\n", mysqli_connect_error());
  
      die();
  
    }
  
  
  
  
  
      if ($_FILES['fileVideo']['error'] === UPLOAD_ERR_OK) { 
  
  
  
  $result = 0;
  
  
  
  
  
  if( file_exists("VideoFiles/".$_FILES['fileVideo']['name'])) {
  
      $parts = explode(".",$_FILES['fileVideo']['name']);
  
      $ext = array_pop($parts);
  
      $base = implode(".",$parts);
  
      $n = 2;
  
  
  
      while( file_exists("VideoFiles/".$base."_".$n.".".$ext)) $n++;
  
      $_FILES['fileVideo']['name'] = $base."_".$n.".".$ext;
  
  
  
      move_uploaded_file($_FILES["fileVideo"]["tmp_name"],
  
      "VideoFiles/" . $_FILES["fileVideo"]["name"]);
  
      $result = 1;
  
  
  
  }
  
      else
  
        {
  
        move_uploaded_file($_FILES["fileVideo"]["tmp_name"],
  
        "VideoFiles/" . $_FILES["fileVideo"]["name"]);
  
        $result = 1;
  
    }
  
  
  
      $videosql = "INSERT INTO Video (VideoFile) 
  
      VALUES (?)";
  
  
  
          if (!$insert = $mysqli->prepare($videosql)) {
  
        // Handle errors with prepare operation here
  
      }
  
  
  
      //Assign the variable
  
  $vid = 'VideoFiles/'.$_FILES['fileVideo']['name'];
  
  
  
              //Dont pass data directly to bind_param store it in a variable
  
  $insert->bind_param("s",$vid);
  
  
  
   $insert->execute();
  
   $id = $mysqli->insert_id;
  
  
  
          if ($insert->errno) {
  
            // Handle query error here
  
          }
  
  
  
          $insert->close();     
  
  
  
          }else{
  
    echo "Upload was not successful";   
  
    }
  
  
  
  ?>
  
  
  
   <code class="echappe-js">&lt;script language=&quot;javascript&quot; type=&quot;text/javascript&quot;&gt;<br />
  
   window.top.stopVideoUpload(&amp;lt;?php echo $result; ?&gt;,&amp;#39;&amp;lt;?php echo $id; ?&gt;&amp;#39;, &amp;#39;&amp;lt;?php echo $_FILES[&amp;#39;fileVideo&amp;#39;][&amp;#39;name&amp;#39;]; ?&gt;&amp;#39;);<br />

  Now I am using a jwplayer and it requires video files to match video formats on this page :

  http://www.longtailvideo.com/support/jw-player/jw-player-for-flash-v5/12539/supported-video-and-audio-formats/

  So I need to be able to encode files automatically on the server when the file is uploaded into the server. I do not want the user to try and encode a video file manually by themseleves, I want it done automatically. But my question is how can I get automatic server side file encoding to work ?

  I have a demo showing how a video file is uploaded : DEMO

  To use Demo :

  1. Click on Add Question button and file input will appear in table

  2. Click on upload straightaway and you will see a simple validation stating which video file format are allowed (this is simply done by checking video file extension)

  3. Browse for a video file, select and then click on Upload and wait for upload to finish (I recommend a short video file for saving time). When file is uploaded it will display success message and video file is uploaded into server,
