I am using an NVidia GTX 1050 as a GPU on my computer running Debian 10. I followed this guide to get the drivers installed :
* Cuda installation guide on Linux
Using the package manager method
Also I compiled ffmpeg using this guide :
* FFMpeg with NVidia gpu guide
Following are the logs from :
- nvidia-smi command
