One feed, three destinations: we built our own multistream relay

We needed one live show to reach every platform at once, in landscape and vertical at the same time. Instead of renting another tool, we built the relay ourselves from free open-source parts. One feed in, three destinations out — two landscape copies and one vertical re-encode — and the master recording kept rolling even when we hard-killed a destination to test it. Then we built the control panel on top: each platform on or off, one Go Live button. Software cost was zero. Testing it by breaking it is what made us trust it.
