QuickSync H.264 - QVBR

[santer]

My Processor i7-4790K(Haswell) (4th Generation Intel® Core™ i7 Processors)
Windows 10x64

But I didn't find QVBR in OBS Studio

QVBR : alsosets a target quality level, QVBRQuality parameter through mfxCodingOption3 and a target bitrate for scenarios where variability may need to be limited, such as game/display streaming scenarios. This algorithm tries to achieve the subjective quality with minimum no. of bits while trying to keep the bitrate constant and HRD compliance is being followed. QVBR is supported from 4th generation Intel® Core processor(codename Haswell) onward.

afaik QuickSync implementation is not yet complete in obs

Yeah, the NVENC implementation is also missing some kind of QP/CRF functionality. I really do hope they're added at some point.

Intel MSDK is constantly evolving and it's hard to capture every capability on the first try, and this is my first try (in the new code base anyways.) Will keep that in mind next time.
