My PlayTube-based video platform is already online, but the storage layer is still pointed at the server’s local disk. I need the whole site—especially the standard video upload flow—properly wired to my existing AWS S3 bucket so that every file is saved, fetched and served from S3 without errors or slowdowns. Here is what matters most to me: • Uploads must land in S3 and be retrievable for playback (file upload and download are the only required S3 actions). • The upload handler has to accept every file type the script supports—full-length videos, shorts, thumbnails, even future formats—without manual tweaks. • Livestreams and shorts are already routed through the same pipeline, so once uploads are working they should automatically benefit; no extra streaming logic is required right now. The framework, AWS account and S3 bucket are all set up; you just need to connect the dots in the PHP code, adjust any CORS or IAM policies, and verify the changes on the front-end HTML templates. Please finish, test and hand over within 48 hours, including a brief note on any code or config files you touched so I can maintain them later.
