Nvidia-smi shows encoder usage at zero - while using h264_nvenc - regression?

I recently upgraded to an RTX 4070, and now I notice that nvidia-smi shows 0% usage for nvenc, on Linux.


 Utilization
        Gpu                               : 20 %
        Memory                            : 9 %
        Encoder                           : 0 %
        Decoder                           : 27 %
        JPEG                              : 0 %
        OFA                               : 0 %

This is despite nvidia-smi encodersessions clearly showing that encoder is in use.

Using Driver versions:

NVIDIA-SMI 545.23.08              Driver Version: 545.23.08    CUDA Version: 12.3

It would be awesome to know if this is a known issue - I rely on this information for performance tuning…

Thanks!
