Media Release Notes

New information about broadcast metrics and events is now available in Cloudflare Stream in the Live Input details of the Dashboard.

You can now easily understand broadcast-side health and performance with new observability, which can help when troubleshooting common issues, particularly for new customers who are just getting started, and platform customers who may have limited visibility into how their end-users configure their encoders.

To get started, start a live stream (just getting started?), then visit the Live Input details page in Dash.

See our new live Troubleshooting guide to learn what these metrics mean and how to use them to address common broadcast issues.

Source origin restrictions in Media Transformations beta

We are adding source origin restrictions to the Media Transformations beta. This allows customers to restrict what sources can be used to fetch images and video for transformations. This feature is the same as --- and uses the same settings as --- Image Transformations sources.

When transformations is first enabled, the default setting only allows transformations on images and media from the same website or domain being used to make the transformation request. In other words, by default, requests to example.com/cdn-cgi/media can only reference originals on example.com.

Adding access to other sources, or allowing any source, is easy to do in the Transformations tab under Stream. Click each domain enabled for Transformations and set its sources list to match the needs of your content. The user making this change will need permission to edit zone settings.

Cloudflare Stream has completed an infrastructure upgrade for our Live WebRTC beta support which brings increased scalability and improved playback performance to all customers. WebRTC allows broadcasting directly from a browser (or supported WHIP client) with ultra-low latency to tens of thousands of concurrent viewers across the globe. Additionally, as part of this upgrade, the WebRTC beta now supports Signed URLs to protect playback, just like our standard live stream options (HLS/DASH). For more information, learn about the Stream Live WebRTC beta.

Images Bindings

You can now interact with the Images API directly in your Worker.

This allows more fine-grained control over transformation request flows and cache behavior. For example, you can resize, manipulate, and overlay images without requiring them to be accessible through a URL.

The Images binding can be configured in the Cloudflare dashboard for your Worker or in the wrangler.toml file in your project's directory:

Configuration

Within your Worker code, you can interact with this binding by using env.IMAGES .

Example usage

Here's how you can rotate, resize, and blur an image, then output the image as AVIF:
