  checkasm : updated tests for sw_scale
  Change the reference to exactly match the C reference in swscale,
  
  instead of exactly matching the x86 SIMD implementations (which
  
  differs slightly). Test with and without SWS_ACCURATE_RND - if this
  
  flag isn't set, the output must match the C reference exactly,
  
  otherwise it is allowed to be off by 2.
  Mark a couple x86 functions as unavailable when SWS_ACCURATE_RND
  
  is set - apparently this discrepancy hasn't been noticed in other
  
  exact tests before.
  Add a test for yuv2plane1.

• PHP : Convert file with FFMPEG and upload to S3 using shell_exec() and aws cli tools

  18 septembre 2017, par andreaem

  I need a script that handle the upload of a video file from dropzone.js, convert to m4v then generate 5 thumbnails using the name of file appending -(number) to each jpg file (eg : file-1.jpg, file-2.jpg, file-3.jpgetc) and finally upload to s3 using shell_script (or maybe if there is a better way to do this).

  Recap

  1. Upload file in a temp dir
  2. Convert file to .m4v
  3. Generate 5 thumbnails from video
  4. Upload the converted video to Amazon S3
  5. Delete local video file

  Here is my code, at the moment I don’t know where the file goes and nothing seems to be uploaded to Amazon S3 (doing the upload in command-line works, so the credentials are ok).

  Dropzone.js

  $("#dZUpload").dropzone({
  
       url: "/ajax/admin/admin.acceptVideo.php",
  
       maxFilesize: 200,
  
       renameFile: new Date,
  
       acceptedFiles: "video/*",
  
       addRemoveLinks: true,
  
       success: function (file, response) {
  
            var imgName = response;                              file.previewElement.classList.add("dz-success");
  
            console.log("Successfully uploaded :" + imgName);
  
            $('#form_video').val(file);
  
       },
  
       error: function (file, response) {file.previewElement.classList.add("dz-error");
  
       }
  
   }).autoDiscover = false;
  
      Dropzone.prototype.defaultOptions.dictRemoveFile = "Rimuovi file";
  
      Dropzone.on("addedfile", function(file) {
  
          var cancelLink = Dropzone.createElement('<a>Cancel upload</a>');
  
       file.previewElement.appendChild(cancelLink);
  
       cancelLink.addEventListener("click", function(e) {
  
       e.preventDefault();
  
       myDropzone.cancelUpload(file);
  
   });
  
  });

  PHP

  $target_dir = "/var/www/html/example.com/web/temp/";
  
  $target_file = $target_dir . basename($_FILES["file"]["name"]);
  
  $uploadOk = 1;
  
  $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
  
  // Check if image file is a actual image or fake image
  
  if(isset($_POST["submit"])) {
  
      $check = getimagesize($_FILES["file"]["tmp_name"]);
  
      if($check !== false) {
  
          echo "File is a video - " . $check["mime"] . ".";
  
          $uploadOk = 1;
  
      } else {
  
          echo "File is not an image.";
  
          $uploadOk = 0;
  
      }
  
  }
  
  // Check if file already exists
  
  if (file_exists($target_file)) {
  
      echo "Sorry, file already exists.";
  
      $uploadOk = 0;
  
  }
  
  // Check file size
  
  if ($_FILES["fileToUpload"]["size"] > 200000000) {
  
      echo "Sorry, your file is too large.";
  
      $uploadOk = 0;
  
  }
  
  // Allow certain file formats
  
  if($imageFileType != "mp4" && $imageFileType != "mov" && $imageFileType != "avi" && $imageFileType != "m4v" ) {
  
      echo "Sorry, only MP4 MOV AVI M4V files are allowed.";
  
      $uploadOk = 0;
  
  }
  
  // Check if $uploadOk is set to 0 by an error
  
  if ($uploadOk == 0) {
  
      echo "Sorry, your file was not uploaded.";
  
  // if everything is ok, try to upload file
  
  } else {
  
      if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {
  
          S3Up(VideoConvert(basename( $_FILES["file"]["name"]),random_int('1','9999')));
  
          echo "The file ". basename( $_FILES["file"]["name"]). " has been uploaded.";
  
      } else {
  
          echo "Sorry, there was an error uploading your file.";
  
      }
  
  }
  
  
  
  function VideoConvert($video, $id) {
  
      shell_exec('ffmpeg -i ' . $video . ' /var/www/html/example.com/web/temp/' . $id . '.m4v');
  
      for ($i=0;$i <= 5;$i++) {
  
          shell_exec('ffmpeg -i ' . $video .' -vf "select=gte(n\,' . $i .'00)" -vframes 1 ' .$id . '-' . $i. '.jpg');
  
      }
  
  
  
      return '/var/www/html/example.com/web/temp/' . $id . '.m4v';
  
  }
  
  
  
  function S3Up($video) {
  
      shell_exec('aws s3 cp ' . $video .' s3://example-video/ --grants read=uri=http://acs.amazonaws.com/groups/global/AllUsers');
  
      sleep(1);
  
      //shell_exec('rm '. $video);
  
  }

  Here is my error.log line relating to s3 upload :

  error.log

  example.mp4: No such file or directory
  
  Traceback (most recent call last):
  
    File "/usr/local/bin/aws", line 19, in <module>
  
      import awscli.clidriver
  
    File "/usr/local/lib/python2.7/dist-packages/awscli/clidriver.py", line 17, in <module>
  
      import botocore.session
  
    File "/usr/local/lib/python2.7/dist-packages/botocore/session.py", line 26, in <module>

      from dateutil.parser import parse
  
  ImportError: No module named dateutil.parser
  
  </module></module></module></module>

  How can I improve this ? I’ve tried using aws php api but got some problems with credentials, cli tools don’t have.

  Behavior

  At the moment dropzone.js stop uploading at 50% if I put a file of 8 MB, php maxUploadSize directive is set to 201M, php upload temp folder is inside the site root directory and permissions set to 7777. File where uploaded if I put a smallest file of 200Kb but don’t convert and make a 0 byte file.
