• 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
  
  
  
              ]);

• Packing a binary into AWS Lambda for Python

  17 novembre 2016, par Anthony G

  I want to convert m4a files uploaded to S3 to mp3. The files would only be 15 seconds max, so using Elastic Transcoder would be overkill. I downloaded a binary from https://www.johnvansickle.com/ffmpeg/. But I am very new to AWS and im still not sure how uploading binaries works. How would I would include it so that I could convert a file ?

  import boto3
  
  import urllib
  
  
  
  print('Loading function')
  
  
  
  s3 = boto3.client('s3')
  
  
  
  def lambda_handler(event, context):
  
      bucket = event['Records'][0]['s3']['bucket']['name']
  
      key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key'].encode('utf8'))
  
      try:
  
      #convert to mp3
  
      #upload to bucket
  
      except Exception as e:
  
          print(e)
  
          print('Error getting object {} from bucket {}. Make sure they exist and your bucket is in the same region as this function.'.format(key, bucket))
  
          raise e
