Hello,
Last year or so I was trying to learn about x264 encoding when I got my new chip, 16thread ryzen 7 3700x.
After a lot of tinkering and reading, source codes forum posts and all, I found something called "b pyramid" and in this website which is no longer available,there was a blog post about it at:
https://www.ramugedia.com/hierarchical-b...-b-pyramid
But to make use of the B Pyramid structure of x264 encoder, GOP length should be multiplies of 2^n like 64 or 128
This trick back then, improved the quality of CBR 6000 stream which I was aiming. Only oddity was using 64 Fps with GOP length of 128
My commandline options for x264 encoder in obs were:
Skipping to present, I was finally able to upgrade the gpu to 3080ti (I upgrade only in 10 years) and now I would like to do the same trick with NVencoder, but FFMPEG doesn'T have too many options, I have tried reading nvencoder header file to get the variables in it but It is not accessible as x264. Unfortunately. Classic nvidia I guess. Most of the stuff I have been trying to add to obs command line option keeps refusing it, and up-to-date variable sheet is nowhere to be found.
Is there a way to tweak gpu encoder to do the same trick? x264 was beautiful with this. I wonder
Thanks
