YES! That did the trick. Jriver (JRVR engine) is now showing the Dolby Vision flag in its OSD, when it previously was not.
Thank you! I will post this on their forum that SVP with JRiver supports their implementation of DV.
I posted your response to their beta forum (I can't link directly to it since it is beta and they just added DV support). This is the response I got:
The metadata was updated in LAV 0.80 to include DoVi extensions, so they would need to cover that change, if they don't already.
I used the JRiver player combined with SVP and AVISynth. JRiver recently added "limited Dolby Vision processing on Profile 7 video streams (similar to a Profile 8.1 stream), including the new per-scene brightness data".
Unfortunately it doesn't appear that using SVP with AVISynth passes through any DV data. I got a reply from one of the JRiver developers:
"I had a look at the Avisynth Filter they recommend to use, and while it processes some basic HDR metadata, I see no trace of supporting DoVi metadata, neither the old or the new version with the extension data. Someone tried to add support some time ago but it never got anywhere. Either way, the filter would need to forward the metadata from LAV Video to JRVR, thats the only way it can cooperate with DoVi."
Hoping this could be added in the future. Thanks!
Any ideas on how to stop crashing due to Avisynth Filter?

Thanks for the reply.
No, it only happens occasionally, maybe once per day. I can stop and start the same file numerous times without the green flash. Seems to happen on different files (mkv 4k UHD rips).
At the beginning of playback, occasionally, maybe once a day, I notice a completely green screen that flashes for a half second and then the video plays. Anyone know why and how to prevent this?
.
I've got SVP working very well with minimal to no noticeable artifacts in most scenes in movies. However, at the beginning of certain movies where this is white or almost white text on black backgrounds, the text flickers really bad. See attached screenshot. Is there any way to fix or minimize this? Is there a way to get SVP to not do any processing in these types of scenes? I Really just need it for panning scenes on my OLED.
I've attached a screenshot of my settings as well. I'm running the screen refresh rate at 120hz fyi.
I know there are lots of undocumented advanced settings that I have no idea what they do. Any help is appreciated! Thanks!
