Wowza 4.7, NVIDIA NVENC and CUDA problems with only 1 transcoded stream
I have NVIDIA K80 card running on Azure N-Series machine, Wowza configured to encode using NVENC and decode using NVCUVID. With only 1 stream, I'm seeing these logs indicating problems:
TranscodingSession.updateBehindFilter[phlive/_definst_/tester]: Video behind filter state change. New state: ALLFRAMESOFF TranscodingSession.updateBehindFilter[phlive/_definst_/tester]: Video behind filter state change. New state: KEYFRAMESONLY
Please tell me what is wrong.
Confirmed the GPU is available:

Hello @edaich,
Make sure you have the latest drivers Tesla drivers installed on the Azure instance.
I believe the latest drivers as of today is version 385.08.
If updating the drivers fail, our support staff would need to take a further look at the configuration and logs data set from your server in order to identify the issue. Please open a new ticket here.
