tl;dr: The author bypassed the PS5's streaming restrictions by using dnsmasq to spoof Twitch's ingest domains, redirecting the console's RTMP broadcast to a local nginx-rtmp server on their Mac. The key trick was targeting `contribute.live-video.net` subdomains, which use plain RTMP (port 1935) rather than RTMPS, avoiding certificate validation issues. The captured stream can then be piped into mpv, OBS, or Discord — replacing the need for a capture card.
