NVIDIA NVENC new preset

[Isalight]

Describe the Bug

Nvidia has made new presets for nvenс. In the next driver / video codec sdk updates old presets will be removed after Q1'2023.

https://developer.nvidia.com/blog/introducing-video-codec-sdk-10-presets/ https://docs.nvidia.com/video-technologies/video-codec-sdk/deprecation-notices/index.html

Expected Behavior

Replace old preset to:

• p1 (perfomance)
• p2
• p3
• p4 (default)
• p5
• p6
• p7 (quality)

Delete old rate control:

• cbr_ld_hq
• cbr_hq
• vbr_hq

Add tuning info and multi pass settings.

Additional Context

Performance comparison of all presets https://github.com/Xaymar/obs-StreamFX/wiki/Encoder-FFmpeg-NVENC#performance-measurements

OBS implementation https://github.com/obsproject/obs-studio/commit/d7c7180a8c55498a484d6e3b132f23e69ab3d553

I compared the old presets with the new ones according to the migration guide. Used ffmpeg-2022-06-16-git-5242ede48d to encode "Spider-Man Into the Spider-Verse" trailer with settings

• -c:v hevc_nvenc -preset llhq -rc cbr -b:v 20M (identical to current default settings)
• -c:v hevc_nvenc -preset p4 -tune ll -rc cbr -b:v 20M
• -c:v hevc_nvenc -preset p4 -tune ull -rc cbr -b:v 20M

The new preset showed better encode time with slightly lower quality.

And try multi pass encode according to recommended NVENC settings -multipass qres. https://docs.nvidia.com/video-technologies/video-codec-sdk/nvenc-video-encoder-api-prog-guide/index.html#recommended-nvenc-settings
