• Use window.innerWidth to detect mobile devices.

  Use window.innerWidth to detect mobile devices.
  Although window.orientation works well to detect mobile devices for now, it is deprecated and might be unreliable.

  Using the viewport size is also a better approach for hiding/showing additional view elements.
  

• PHP - Upload video convert mp4 and upload to Amazon S3

  31 octobre 2019, par Kadir Geçit

  I’m using amazon s3 as video storage for my website. I’m having problems for some videos. black screen or sound problems etc.

  I want to convert the video to mp4 format after uploading the video to my server and then upload it to amazon. Is it possible with FFMPEG ?

  I’m using this code for uploading files now :

  $file1 = $_FILES['file']['name'];
  
  $videoFileType = strtolower(pathinfo($file1,PATHINFO_EXTENSION));
  
  $file_name = sprintf('%s_%s', uniqid(),uniqid().".".$videoFileType);
  
  $temp_file_location = $_FILES["file"]["tmp_name"];
  
  
  
  require 'application/libraries/Amazon/aws-autoloader.php';
  
          $s3 = new Aws\S3\S3Client([
  
              'region'  => $amazon_region,
  
              'version' => 'latest',
  
              'credentials' => [
  
              'key'    => $amazon_key,
  
              'secret' => $amazon_secret,
  
              ]
  
          ]);     
  
  
  
          $result = $s3->putObject([
  
              'Bucket' => $amazon_bucket,
  
              'Key'    => $file_name,
  
              'SourceFile' => $temp_file_location,
  
              'ACL'    => 'public-read',
  
              'CacheControl' => 'max-age=3153600',
  
          ]);
  
              $filepath = $result['ObjectURL'] . PHP_EOL;
  
  
  
              echo json_encode([
  
                  'status' => 'ok',
  
                  'path' => $filepath
  
  
  
              ]);

• look for a specific filetype in a directory in php and send it to a different directory after conversion

  12 juin 2019, par flash

  I have a directory in which there is a mp4 file (including other files as well) which I want to convert into mp3 and then send it to different directory. I have used the following command line command to covert into mp3 and its working perfectly fine.

  ffmpeg -i 36031P.mp4 -map 0:2 -ac 1 floor_english.mp3 

  mp4 file is inside in_folder. Using ffmpeg, I want to convert mp4 file into mp3 and send it to out_folder.

  <?php
  
  $dir    = 'in_folder';
  
  $files1 = scandir($dir);
  
  print_r($files1);    /* It lists all the files in a directory including mp4 file*/
  
  ?>

  print_r($files1) lists all the file in a directory including mp4file.

  Problem Statement :

  I am wondering what php code I need to write so that it looks for only mp4 file inside the directory and send it to different directory (let say out_folder) after converting into mp3.
