madVR HDR to SDR settings not working

[mkdrive2]

Hello, I have an SDR monitor dell p2416d. I am trying to watch https://hdrsamples.com/life-of-pi-4k-uhd-hdr-sample-footage/

No matter how I change the HDR settings, the image looks the same. For example I tried HDR passthrough and "convert HDR content to SDR by using pixel shader math" with target peak nits of 100, 200, and 800. No difference at all.

Is there something I can do?

Edit: I get the "Please update LAVFilters to the latest version..." message at the start of the video. Could it be that that is one reason why it is not working?

Thanks, with the new LAV Filters the HDR to SDR conversion is working. I was still using the LAV Filters from the ancient CCCP build. I copied all the settings to the new LAV Filters.

never use codec packs, use the official installers of the projects
