Cloudflare publishes long-running streams on the public MoQ relays. Use these streams to test client implementations without setting up your own publisher.
The relays host the following namespaces. A check mark indicates that a namespace is available for that draft.
| Namespace | Draft-14 | Draft-16 |
|---|---|---|
/bbb |
✅ | ✅ |
/demo-tos-360p |

moq-sub from the moq-rs ↗︎ project writes the media as fragmented MP4 to standard output. Select a draft to view the matching command.
Draft-14 supports every namespace in the table. This example subscribes to /bbb:
moq-sub https://draft-14.cloudflare.mediaoverquic.com --name bbbDraft-16 supports only /bbb. Its relay URL includes the provided JSON Web Token (JWT):
