Contribution shapes — dial out, mezzanine out
The channel as a contribution link rather than a player origin. It can dial out to an upstream sender over SRT-caller and deliver two shapes at once — a CMAF ladder for players plus an SRT mezzanine for downstream contribution — or run mezzanine-only with CMAF off, the smallest shape that delivers nothing to players at all. The repo carries both as ready-made configs (srt-caller-cmaf-srt, srt-egress-only); the delivery surface is the same screen either way.

Section titled “01 The mezzanine route”An SRT egress carrying the programme downstream, here alongside the CMAF ABR output — turn CMAF off and the mezzanine stands alone, each route with its own health.
