I have 2x4k yuv 4:4:4 raw streams (about 225MB/s per stream) coming from two cameras, which i would like to encode with ffmpeg using h265 on the GPU. We currently have the Nvidia Quadro P5000 as working setup, which needs about 40% of the available GPU power. Since this graphic card is quite expensive, how can we know which cheaper GPU has still the needed power to encode the video streams?
full ffmpeg settings to capture
Thanks for your help!
Code: Select all
ffmpeg -f decklink -i "capture_card" -map 0:v -an -c:v hevc_nvenc -preset slow -rc constqp -qp 30 -vf format=yuv420p -g 150 output.mp4
