explicit option for splitframeencoding

[miscrtnone]

splitframeencoding is also now available on newer, higher nvidia consumercards. some time ago it was only activatable implicitly von some presets, now it can be turned on explicitly https://developer.nvidia.com/blog/video-encoding-at-8k60-with-split-frame-encoding-and-nvidia-ada-lovelace-architecture/ without the restrictions from before.

quote:
"With NVIDIA Video Codec SDK 12.1, you can enable or disable the SFE feature. This means that SFE can now be used to take advantage of two or even three NVENCs present within the NVIDIA RTX 4090 and the NVIDIA RTX 6000 Ada Generation, respectively, without resolution, preset, and tuning information restrictions. This enables the application to double or even triple the encoding performance when encoding a single video sequence by using a two-way or three-way SFE. "

i really would like to see an option to turn it on explicitly in alvr. it would make a good fit to alvr's options to choose from different encoding presets.
