Sure I could OSS them, would also alleviate the problem of hosting them for me. They are really not much code, was more the research for me. I guess some additional eyes and ideas can improve them still, they were not really intended to become OSS, eherm ;). Blackmagic driver support would be nice indeed 🙂 Should I contact you directly somehow when I got “per-cam-hotness” working? Everything else seems to work fine so far, some threading could be more elegant but its safe so this would probably be the last thing I’d do for myself.
