Neither your "FX6_Sample.mp4" (HEVC 4:4:4 but 25fps and low bitrate) or my HEVC UHD HDR 10Bit 444 50fps.mov uses HW Accelerated in either JRiver Media Center or MPC-HCx64 (from your zip file) with LAV set to CUVID. They all drop back to SW Decoding (avcodec) in LAV.

That's better - thanks but I've asked about ffmpeg -benchmark... test with FX6_Sample.mp4 and (if hardware decoding not work with 50fps but due test with HEVC UHD HDR 10Bit 444 50fps.mov I'm sure Ampere can - may be Turing can't) FX6_Sample_25fps.mp4 - it was at http://forum.doom9.org/showthread.ph...08#post1934308

What do you think - is it possible to add support of 4:4:4 h265 in LAV Video Decoder via CUVID for nVIDIA's Turing and Ampere owners like jmone and (may be - I don't know exactly) you?
May be its time for adding Dolby-E support https://github.com/FFmpeg/FFmpeg/com...dd7b8fad188add in LAV Audio Decoder I've asked http://forum.doom9.org/showthread.ph...35#post1928735 with Sample Eurovision 2019 Tel Aviv.ts contained Dolby-E audiotrack there?

He has already said that CUVID is deprecated. Don't expect any updates for it. Plus CUVID does not support exporting HDR metadata, so it is becoming useless.

There is no Dolby-E decoder in FFmpeg yet. Only a parser.
