NVIDIA H264/H265 decoder/encoder monitoring
You can use either –query-gpu option:
nvidia-smi --query-gpu=utilization.decoder --format=csv
Example output:
utilization.decoder [%]
9 %
Or dmon:
nvidia-smi dmon
Example output:
# gpu pwr gtemp mtemp sm mem enc dec jpg ofa mclk pclk
# Idx W C C % % % % % % MHz MHz
0 - 40 - 3 2 0 19 - - 3504 1290
With little explanation:
sm: CUDA streaming multiprocessor?
mem: GPU memory
enc: encoder in NVENC
dec: decoder in NVDEC
