I see... Thanks for this new build, but I would still change a thing.
(I know, I know, you are gonna hate me right now xD).
I tried to open a 10bit file and it says "no suitable output format found", as expected.
I tried to output an 8bit dithered video from a 10bit source and it worked, as expected.
I then tried to output a 16bit video via the 10bit hack, but it didn't work.
My question is: how can I output a 16bit video (stacked - Dither Tools - or interleaved - HDRCore) in plain Avisynth via ffms2 C plugin?
I think you should enable the 10bit hack for Avisynth users, otherwise we won't be able to preserve the bitdepth of the source.

FFVideoSource("jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv")

no suitable output format found

---

FFVideoSource("jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv", enable10bithack=true)

FFVideoSource does not have a named argument "enable10bithack"

---

FFVideoSource("jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv", colorspace="YV12")

Works: output is dithered down 8bit 4:2:0 video

Thank you in advance.
