01> HOW IT SHIPPED
// THE CHALLENGE01
Uploading a video is the easy half. Returning four renditions, a live stream and honest progress — while the file is still moving — is the half that fails in front of the customer.
// THE APPROACH02
FastAPI over ffmpeg for a 360p to 1080p ladder, RTMP in and HLS out for live, MinIO tuned for large multipart uploads, Supabase JWTs at the edge, and per-quality progress pushed over WebSocket and SSE rather than polled.
// THE OUTCOME03
A client uploads once and watches each rendition finish on its own clock, with a failure reported against the quality that failed instead of collapsing the whole job into one opaque error.
