Is there any timeline for driver 450.xx support? My system already has it installed, and I have not seen any effect.

It will be in 2021, but do not have an ETA for you yet Egbert.

@Rose_Power-Wowza_Com thank you for the reference to NVIDIA 450.xx drivers. Just to echo the warning and in case others find this via search…

I am using 4.8.5 and discovered that using NVIDIA 450.xx drivers can cause problems for certain GPU operations. The result is loss of video. Sometimes (but not always) there will be error messages in the log like this:

TranscodingSession.updateBehindFilter[xxxx/definst/xxxx]: Video behind filter state change. New state: SKIP1FRAME

One of my systems auto updated from 440.xx → 450.xx during a reboot, so it caught us off guard. I’m not sure which operations caused this, but this came up in CUDA / NVCUVID / NVENC / overlay.

I resolved by either holding at 440.xx or downgrading from 450 to 390.
