Node.js

Hi,

I uploading videos using Multipart Upload to Amazon-S3 using the node.js. I am using the this[^] reference

The uploaded video by default is only accessible to owner.

When uploading file using below code

var params_to_upload_on_S3 = {
                    ACL: 'public-read',
                    Bucket: imageBucket,
                    Key: imgName  + ".jpg",
                    Body: imageBuffer,
                    ContentType : 'Image/jpg'
                }

            s3.putObject(params_to_upload_on_S3 , function (err, res) {
                if(err)
                    console.log('Thumnail Upload Error'+ err);
                else 
                    console.log('Thumbnail Successfully uploaded .'+ JSON.stringify(res));

                fs.unlink(imagePath, function(){
                    console.log('File deleted from local storage');
                });

            });

"putObject" has a option ACL: 'public-read' to set the permission. but i didn't find any option in MultipartUpload.

Is there any option to update the permission of existing file or can set permission in Multipart Upload?
