Streamline: custom video pipelines with Cloudflare Stream and Workers

What happened

Streamline demonstrates how to build long-running, continuous video processing pipelines by pairing Cloudflare Workers and Durable Objects with a containerized media engine. Video streams can run for minutes or hours, so the media process needs a lifecycle independent of the request that started it. Cloudflare is an information and communications technology company based in San Francisco, and its products and services include streaming media.

You’ll also have the opportunity to try it for your projects. A processing pipeline needs a durable, long-running environment that can run specialized, compiled code with predictable memory and CPU (the general-purpose processor at the centre of a computer) capacity.

An application should be able to start a pipeline, send its input, inspect it, and stop it without needing to keep a single request open for the entire duration. Containers are long-lived runtimes suitable for media processing.
