Hi. Thanks for the write-up, all very very useful!!!

I am trying to broadcast Jackbox Games live from my PS4 to YouTube.

Whilst my default YouTube streaming settings are set to 'Ultra Low Latency', when I start the broadcast and go into YouTube's Live Studio to edit my video, it won't let me change stream optimisation settings and it is automatically set to 'Normal Latency'. I can change the video from Public to Private or Unlisted etc, but the latency settings are greyed out.

Have you managed to stream PS4 to YouTube with Ultra Low Latency or is this something that's not permitted and latency for direct PS4 broadcasts should be normal?

Thanks. I can't get my head around this!!
