I use <a href="https://github.com/kaihendry/s3post" rel="nofollow">https://github.com/kaihendry/s3post</a> to upload videos to lambda, convert them to mp4 and share them on a CDN for sharing.<p>Problem is when uploading from a Webform, IOS downscales the original file which I hate. Does this app get around that problem? If so, be good if I could post to my own S3 endpoint!
