Interactive Live Streaming

Shig combines real-time media technologies to make live streams interactive, bringing cameras, guests and audiences together.

Connected through the Fediverse

The next step is federation through ActivityPub, enabling communities to discover and share live events across the Fediverse.

Scale only for your own community

Shig’s cascading SFU and Relay server architecture is designed to spread delivery across connected fediverse servers. Each fediverse server serves its own users, instead of making one server serve the entire Fediverse audience.

The technology behind Shig

WebRTC stream fan-out via Media over QUIC

Cameras and guests connect in a WebRTC conference lobby powered by a Rust-based SFU. Inside the lobby, their streams are mixed into a single stream that remains available as a regular WebRTC stream.

The Rust SFU converts the mixed stream to Media over QUIC (MoQ) and forwards it to relay servers, which distribute it to the audience.

WebRTC lobby → Media over QUIC → Relay servers → Live audience

Shig: distribute and clone live streams among Fediverse instances

Talk on the FOSDEM 2024

In the talk at FOSDEM’24, we demonstrated how interactive live streaming is possible within the Fediverse. Towards the end, it became evident how crucial bandwidth estimation is, and this will be the next major feature in Shig.
