A look inside Metro: The ABC's new media transcoding service

The ABC, Australia's national public broadcaster, recently launched a new transcoding system that converts media into suitable formats for the catch-up tv service, iview. It is cost-efficient, scalable, and has successfully processed thousands of pieces of content since going live in December 2015.

Metro has been built using golang, node.js, and ffmpeg, and heavily utilises a variety of AWS technology including queues, varied capacity autoscaling, hosted database servers, and notifications.

This talk will cover Metro's system architecture, how we transcode content, technical challenges we faced, and what we'd like to achieve in future.
