Until recently, the ffmpeg command below used to consistently report NVIDIA CUDA device as number 1.0 and the other as 0.0 (on multiple computers).
Just recently, I noticed that the device numbers (on multiple computers) had swapped around and remained consistently that way across reboots.
I am not sure if that was caused by recent very large Win10x64 update, or a newer build of ffmpeg-with-opencl. Hence I am unsure if the change may affect your software or not.
