• 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 ?

• Turn an FFMPEG script into bat file [closed]

  24 décembre 2022, par Chase Rogers

  Can someone help me turn this code into a bat file.

  


  ffmpeg -i videoName.mp4 -vf fps=1/60 videoName_thumb%04d.png

  


  If you know of a way to make it so that it will automatically use the videos name that would be very helpful as well.

  


  I don't know anything about ffmpeg or bat files, I have been doing copy paste and test. I have found another script to take a space in a file name and turn it into a - so that this ffmpeg script will work. I will also be trying to turn that into a bat file as well, if you know of a bat file script that can do that I would really appreciate it.

  


• Batch script cannot read file if there is a space

  25 août 2022, par Shahpari

  CD "C:\Input"
for %%a in ("*.*") do "C:\ffmpeg.exe" -i %%a -map 0:v -map 0:a:0 -map 0:s -c:v copy -c:a ac3 -b:a 640K "C:\Out\%%~na.mkv"
pause


  


  if there is no space this script works fine, but if there is a space in file name, the script reads only the first word of the file and throws an error. i tried to add a double quote first %%a. but then the script does not even run.

  


  here is an example file name :
[TEST] ABC test - 99
