Hello. 

I am currently poke code of Cinelerra-gg {0} (fork of Cinelerra-HV {1}). Our software (Linux-only, even if you can try to compile on Windows or FreeBSD) tries to be quite high-end NLE with support for 32-bit floating point data path. 

On your product page
https://www.aja.com/products/kona-lhe-plus

I see

"Supporting macOS, Windows and Linux, KONA LHe Plus offers cost effective simple connectivity for a range of workflows."

yet on your (?) driver page
https://github.com/aja-video/ntv2-v4l2

I can't see this specific card listed. 

Does this mean current (hopefully v4l2) drivers for Linux non-public/proprietary? 

Please indicate if I can forward your reply to our public mail list (cc-ed), or should I paraphrase it.
