It can be mentioned that rigaya has three equivalent(?) programs:

QSVEnc - for HW encoding with Intel QSV
NVEnc - for HW encoding with NVIDIA NVENC
https://github.com/rigaya/NVEnc
VCEEnc - for HWencoding with AMD VCE
https://github.com/rigaya/VCEEnc

There is also some comparison tools that I haven't expored:

Thanks to responsiveness from malcolmlewis at openSUSE Factory/Build 
Service to build the rpm, I have now QSVEnc running on Slowroll.

QSVEnc has a comprehensive option list and help beyond investigating the 
environment capabilities, which also includes a encoder and decoder.

For example its integration with Avisynth and ffmpeg via pipes may be of 
interest:

pipe usage from ffmpeg

ffmpeg -y -i "<inputfile>" -an -pix_fmt yuv420p -f yuv4mpegpipe - | 
QSVEncC --y4m -i - -o "<outfilename.264>"


Passing video & audio from ffmpeg:

--> use "nut" to pass both video & audio thorough pipe.

ffmpeg -y -i "<input>" <options for ffmpeg> -codec:a copy -codec:v 
rawvideo -pix_fmt yuv420p -f nut - | QSVEncC --avsw -i - --audio-codec 
aac -o "<outfilename.mp4>"

Example outputs from a few checks I have run on my ARC A750 gpu:
