Ok. I’m having tech support take another look at this thread. That error “Video encoder is stuck, recreating.” was happening in 4.8.0 for some folks with your scenario, but was resolved after upgrading to 4.8.5, so our tech support team suspect it was a combination of the OS and GPU model with Wowza Streaming Engine 4.8.0.
But, to make sure you get the correct answer, I am confirming with the engineers the only solution is to upgrade to 4.8.5. Be back soon. Appreciate your patience and communication.
