I've added options to use CQP instead of a set bitrate to the hardware encoders, in the same way that CRF is implemented for x264 and x265. I've only tested this with AMF, but from my research these options seem to be platform-agnostic.
I wasn't fully sure if I should enable it by default since it is a (mildly) breaking change, but I ended up doing it because I was going for "feature parity" with the software encoders. If I should change this, please let me know.
