Hey Restream team,

I'm a Twitch streamer and a Restream user. I'd love to see Restream add support for Twitch's Enhanced Broadcasting (multitrack / ERTMP) on the output side.

The ideal flow: I send Restream a single high-quality feed (say 1440p landscape + a separate 9:16 vertical track), and Restream generates the full ladder of lower resolutions and forwards the multitrack ERTMP stream to Twitch — the same way YouTube and TikTok Live Studio already handle this on their ingest.

Right now, to get 1440p or vertical on Twitch, every streamer has to encode every rung of the ladder on their own PC, which is a huge GPU and upload burden. A cloud transcode + ERTMP output from Restream would solve this for everyone who's already sending you a feed anyway. Streamrun handles the vertical/landscape combining today but still requires all encoding client-side — there's a real gap here and Restream is the natural place to fill it.

Happy to test or give feedback if this is something your team is considering.

Thanks,
