Live network lab

One live stream. Three players. Two delivery paths.

Watch the NASA feed with its millisecond clock through Media over QUIC. On desktop, the Blockcast IWA can receive the same MMTP tracks over native multicast or AMT. Switch between moq-lib, moqtail, and Shaka MSF while keeping your environment and delivery choices. Each player selects from its own authoritative rendition catalog.

Watch NASA live over MoQ now. Native multicast and AMT move to the Blockcast Android and iOS apps after device and store validation.

Compatible players can send aggregate playback counters through the versioned embed contract. The rendition selector receives only catalog-derived video track names and display metadata. This page does not estimate missing values. Stream URLs, namespaces, tokens, and multicast coordinates are excluded from that contract.

Add multicast to this device

The browser demo works over MoQ on every device. Native multicast and AMT use a local Blockcast bridge app; the media pipeline and catalog stay the same.

Android + iOS

Native SDK bridge apps

Native Android and iOS demo builds are being prepared for device and store validation. Until a verified Play or TestFlight destination is published, mobile browsers keep using MoQ unicast.

From viewer to broadcaster

This public demo is playback-only and never receives publishing credentials. Account-scoped publishing remains a roadmap item until namespace and node authorization are implemented and verified.

Planned

Publish with WHIP

Account-scoped WHIP endpoint creation is not available from this demo yet. It will ship only after signed-in namespace and node authorization are wired end to end.

Required boundary

Own your tracks

Publishing must bind track discovery, subscriptions, and revocation to the logged-in namespace. The public playback catalog does not grant that authority.
