  lavc/videotoolboxenc : set extradata when opening codec
  VideoToolbox doesn’t supply parameter sets until the first frame is done
  
  encoding. This spins up a temporary encoder and encodes a single frame to
  
  get this data.

• Ajax call returns 500 error

  26 mars 2018, par user3080392

  I have an Ajax call to a PHP script. The PHP script uses FFmpeg to concatenate several .ts files into one, and then converts it into an MP4 file.

  The PHP script manages to concatenate the files and convert the file to an MP4. However, none of the code after the FFmpeg commands is carried out.

  Furthermore, my Ajax "success" function always returns a "500 Internal Server Error"

  Here’s the Ajax :

  function makeVid(vidUrl) {
  
  
  
    $.ajax({
  
      type: "POST",
  
      url: 'make_vid.php',
  
      data: {url: vidUrl},
  
      cache: false,
  
      success: function(data){         
  
        $("#vidResult").append(data);
  
        document.getElementById(#myBtn).disabled = false;
  
      },
  
      error: function (jqXHR, exception) {
  
        var msg = '';
  
        if (jqXHR.status === 0) {
  
          msg = 'Not connect.\n Verify Network.';
  
        } else if (jqXHR.status == 404) {
  
          msg = 'Requested page not found. [404]';
  
        } else if (jqXHR.status == 500) {
  
          msg = 'Internal Server Error [500].';
  
        } else if (exception === 'parsererror') {
  
          msg = 'Requested JSON parse failed.';
  
        } else if (exception === 'timeout') {
  
          msg = 'Time out error.';
  
        } else if (exception === 'abort') {
  
          msg = 'Ajax request aborted.';
  
        } else {
  
          msg = 'Uncaught Error.\n' + jqXHR.responseText;
  
        }
  
        $('#vidResult').html(msg);
  
      }
  
  
  
    });
  
  
  
  }

  And here’s the PHP/FFmpeg :

  shell_exec("$ffmpeg -f concat -safe 0 -i $vidClipsListTxtFile -c copy $combinedFileTs 1> $makeVidProgTxtFileTs 2>&1");
  
  shell_exec("$ffmpeg -i $combinedFileTs -f mpegts -codec:v mpeg1video -bf 0 -codec:a mp2 -q 12 $combinedFileMp4 1> $makeVidProgTxtFileMp4 2>&1");
  
  echo "video completed.";

  The PHP error log includes the following errors :

  File does not exist: /home/mysite/public_html/favicon.ico
  
  File does not exist: /home/mysite/public_html/404.shtml
  
  File does not exist: /home/mysite/public_html/505.shtml
  
  File does not exist: /home/mysite/public_html/robots.txt

  And here are some of the things I’ve tried to correct the problem :

  1. Created the above files in the public_html folder

  2. Increased the max_execution_time and memory_limit in my php.ini file

  3. Changed the Ajax success() function to a complete() function

  I still get the 500 error. What else can I try ?
