Topic: Nvidia + SVP causing green screen ?

Just reporting, nvidia hardware acceleration causes a green screen in one HDR movie, even when reencoded through ffmpeg from h265 to h265.
If it is an SVP setting that can help, besides deactivation hardware acceleration, please tell. Without hardware acceleration "recoder HDR colors" is not available. Deactivating "try to recoder HDR colors", but leaving hardware acceleartion still on fixes that problem too...
Might be a MplayerHomeCinema problem as well, MVP does not have that issue. But switching from "dvxa2 (copy-back)" to "none" doesn't help there.
Any hints what I missed?
This is, up to now, the only video, for a very long time, exposing such an issue issue.

Re: Nvidia + SVP causing green screen ?

this is a "try to recover HDR colors" bug
but as we have Avisynth Filter now with a HDR pass-through to madVR, this ffdshow+"recover HDR" path looks obsolete
