Building Custom Video Pipelines with Cloudflare Stream, Workers, and Durable Objects
Cloudflare has introduced Streamline, an architectural pattern that combines Cloudflare Workers, Durable Objects, and containerized media engines to build continuous, long-running video processing pipelines.
Cloudflare has introduced Streamline, a design pattern aimed at constructing continuous, long-running video processing pipelines. By combining the serverless capabilities of Cloudflare Workers and the stateful management of Durable Objects with a containerized media engine, developers can now build highly customizable video pipelines without managing complex traditional server infrastructure. Traditional serverless functions often struggle with the state management and extended runtimes required for continuous video ingestion and processing. Streamline addresses this by positioning Durable Objects as a stateful coordinator that manages the lifecycle of containerized media engines, while Cloudflare Workers handle event routing, authentication, and lightweight processing tasks at the edge. Adopting this pattern requires careful consideration of operational parameters, including permission structures, regional execution conditions, and pricing differences compared to standard serverless setups. Teams must plan their migration and resource scaling policies to ensure continuous media processing remains cost-effective and compliant with regional data residency requirements.

Action Checklist
- Enable and configure Durable Objects within your Cloudflare account to manage stateful coordination. Verify that your current subscription tier supports Durable Objects.
- Containerize your custom media engine, such as FFmpeg, to process video streams. Ensure your containerized engine can communicate with the Cloudflare edge network securely.
- Deploy Cloudflare Workers to handle incoming video ingestion events and route them to Durable Objects. Implement robust authentication checks on the ingestion Worker to secure your pipeline.
- Evaluate regional execution requirements and routing policies for compliance. This is crucial if your video data must remain within specific geographic boundaries.
- Review the pricing models for high-frequency Durable Object transactions and container runtimes. Calculate estimated monthly compute costs based on expected video processing volume.
