Cloud Video Streaming Integration

My videos sit in Amazon S3/ Cloudflare storage and I need them to play instantly inside a standard HTML5 player in the browser—on desktop as well as on every modern mobile device. Your job is to wire the storage layer to the front-end so users can click “play” and start watching without waiting for the entire file to download. Key points I want covered • Direct, secure pulling of the file from S3 and Cloudflare (signed URLs or an equivalent method to keep the buckets private). • Smooth playback in Chrome, Safari, Firefox, Edge, and the major mobile browsers, with no reliance on Flash. • A clean, reusable code sample—JavaScript/TypeScript, Node.js, PHP or another lightweight backend is fine—that I can drop into an existing site. • Clear instructions so I can replicate the setup for additional videos. Deliverables 1. Working streaming endpoint(s) that fetch from Amazon S3 and Cloudflare. 2. Front-end snippet demonstrating the player in action on desktop and mobile. 3. Brief README covering environment variables, build/run steps, and any CDN or CORS settings required. Once everything streams smoothly from both storage locations and plays on desktop and mobile, we are done.
