No FPS values displayed by nvidia-smi

We’re using Tesla T4 for H.264 transcoding on Ubuntu. I’m looking for a way to tell the frame rate of the decoded stream. All the options I’ve tried show FPS as blank or zero. What am I missing?

$ nvidia-smi fbcsessions

$ nvidia-smi -q | grep -iP “fps|name|version”
Driver Version : 430.64
CUDA Version : 10.1
Product Name : Tesla T4
VBIOS Version : 90.04.84.00.06
Average FPS : 0
Average FPS : 0

fbcsessions” -> “FBC” is frame buffer capture used by capture SDK for RemoteDisplayProtocols/VDI/GameStream protocols and not for encode/decode/transcoding.
Try “encodersessions” but it does not work also it must be fed by RemoteDisplayProtocols/VDI/GameStream protocols data too.
You must enhance you transcoding application with FPS statistics output (use “dmon” or “pmon” to display ENC or DEC load).

Do you manage to get any FPS? I tried using “dmon” and I do get power, temperatures, clock speed etc but no FPS.

Is there any nvidia-smi query to get FPS?

Thanks in advance!
