Quote:can you guide me through how to use DGDecNV?For Vapoursynth: Extract your DGDecNV 64bit files and your license.txt to
Hybrid\64bit\vsfilters\SourceFilter\DGDecNVEnable "Filtering->Vapoursynth->Misc->Input->Use DGDecNV when available".
For Avisynth: Extract your DGDecNV 32bit files and your license.txt to
Hybrid\32bit\avisynthPluginsEnable "Filtering->Avisynth->Misc->Input->Use DGDecNV".
Quote:NVenc Ffmpeg performance might be better for me though its not showing fps but percentage looks great.NVEnc through NVEncC and FFmpeg should have the same speed.
Quote:dxva2 and d3d11va gives better speed for me.Totally confused, I thought only 'qsv and d3d11va return no error' and d3d11va was faster?
If dxva2 works normal Hybrid should work fine, since that is the default used when 'Use gpu decoding' is enabled.
Quote:is it possible to add HDR patching using nvhsp for Nvenc Ffmpeg?Haven't tried whether it still works for streams created by ffmpeg.

Thanks . I will have time to do some testing this weekend and report.
I upgraded to 2018.02.03.3 seem to break HDR patching.
Quote:Matrix coefficients
Mastering display color primaries
Above works and Below are not writting even those its patched
Quote:Mastering display luminance
Maximum Content Light Level
Maximum Frame-Average Light Level
Please add HDR patching to Nvenc ffmpeg and more Preset instead of HQ only.
sorry for confusion but dxva2 and d3d11va works but no HDR patching on ffmpeg.
next is to try DGDecNV and see if the speed is better

Since you do not share any details I won't look into it.
Assuming you wrap your output into an mp4 container, disaling XPS might help.

RE: hi - encoding really slow - hbb - 10.02.2018
I tested dev version you sent and everything nvenc/ffmpeg seem to be crashing. even upgraded my card drivers.
4k hdr,non-4k, 1080p.. all the same. all crashes
only successful encode is with VCEenc. im sure direct x265 and x264 works but didnt test. not sure what i did wrong.
I will wait to test ffmpeg HDR patching. seem to be some issue with the version or my settings or something
see the logs

RE: hi - encoding really slow - Selur - 10.02.2018
Seems like a crash since Hybrid looks for the wrong output file,..
No,...
1. Does the avisynth preview work? If not then DGDecNV doesn't work with HEVC and your card and driver combination.
2. What happen if you call:

RE: hi - encoding really slow - Selur - 10.02.2018
LOL I see the problem.
When adding nvshp I accidentally removed the output from NVEnc
-> will send you a new version in a few minutes
