This same setup turns my 2018 6-core intel MBP into a screaming fireball. There seems to be very little impact on overall system performance because of this, are others seeing the same thing? Something I noticed about x264 when watching Activity Monitor, when I click Stream or Record, it seems to run on the efficiency cores as the additional load appears on cores 4-8 which otherwise show no activity. There is also a workaround out there to enable hardware encoding, however I could not figure out how to properly control the bit rate, it would jump all over the place 5000kbps one second to over 30000kbps. NDI output works, as does the Virtual Camera in Zoom and Google Meet. The NDI plugin does not work out of the box but there is a GitHub post with a workaround that works:


CamLink 4K capturing mirrorless camera, a couple of NDI sources and window captures, all working super smoothly.

I’ve been setting up an M1 Mini for a live streaming event at work using OBS 26.1.2.
