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. {0} - https://www.cinelerra-gg.org/ {1} - http://www.heroinewarrior.com/cinelerra.php
