• On upload rename the file to input.mp4 not working

  7 mars 2018, par 57_Wolve

  Ok so i’m trying to make it to were the file is uploaded then renamed to input.mp4 so that it over rights the old one. But its not working ?

  But it still keeps uploading with the original file name.
  Or is there a way to just delete the files in the folder uploads after 30 min ? Both the uploaded file and output file.

  <?php
  
  $fileName = $_FILES["file1"]["name"]; // The file name
  
  $fileTmpLoc = $_FILES["file1"]["tmp_name"]; // File in the PHP tmp folder
  
  $fileType = $_FILES["file1"]["type"]; // The type of file it is
  
  $fileSize = $_FILES["file1"]["size"]; // File size in bytes
  
  $fileErrorMsg = $_FILES["file1"]["error"]; // 0 for false... and 1 for true
  
  if (!$fileTmpLoc) { // if file not chosen
  
      echo "ERROR: Please browse for a file before clicking the upload button.";
  
      exit();
  
  }
  
  
  
      $newfilename = $fileName . input.mp4';
  
      rename($fileName, $newfilename);
  
  
  
  if(move_uploaded_file($fileTmpLoc, "uploads/$newfilename")){
  
  
  
    echo "Starting ffmpeg... <br />";
  
    echo shell_exec("ffmpeg -y -i uploads/".$newfilename." uploads/output.mp3");
  
    echo "Done. <br /><br />";
  
  
  
  echo '<a href="http://test.tw-wcs.com:82/ffmpeg/MP4_To_MP3/uploads/output.mp3" target="_blank">Click Here</a> To open your file in a new tab.';

• How to make cropping when doing motion-tracking look super smooth ? (using cv2 and yolo v8)

  4 décembre 2024, par Thomas Lancer

  I'm using yolo to track a face in a video on a frame by frame basis, and then I'm using cv2 to crop the video (with some padding) around the speakers face so it creates a motion tracking type effect. (short example here : https://www.instagram.com/reel/DCIFkFEObkE/?hl=en)

  


  The problem I'm running into is my final crop looks "shaky". Like it's flickering a bit. I think this is because every frame yolo is updating the coordinates, and so there's a slight change in x, y and because of that it creates this shakiness/flickering effect. Here's what mine looks like compared to the example : https://drive.google.com/file/d/1MKHWK-5EH5abSq6i32r71GWld76tN1GP/view?usp=sharing

  


  You can see there's this "shakiness" type look to it. it's especially apparent when the speaker is relatively still.

  


  I've tried doing an exponential moving average and a few other averaging techniques but none have fixed it.

  


  Is my fundamental approach of doing a frame by frame crop wrong ? or is there just some smoothing algorithm or some dumb mistake that you think I may be making ? Any advice is mega appreciated !
