hevc_nvenc: Cannot get the preset configuration: invalid version (15)

[Antony R]

Summary of the bug:
I tried to update FFMPEG from 3.4 to 4.0 (or last Nightly) but the same command-line doesn't work in newer versions.
The errore is: Cannot get the preset configuration: invalid version (15)
How to reproduce:

ffmpeg -report -r 24 -c:v h264_cuvid -i "Film.mkv" -map 0:v:0 -c:v hevc_nvenc -preset hq -b:v 3.0M -r 24 -f matroska -map 0:a:0 -c:a copy -map 0:s:0 -c:s copy "Film HEVC.mkv"

A ZIP containing three logs/reports for ffmpeg3.4, ffmpeg4.0 and ffmpeg_nightly versions

Is a specific input file required or is the issue also reproducible with testsrc?
Please test git current FFmpeg git head, provide the failing command line together with the complete, uncut console output and use git bisect to find the commit introducing the issue.

I'm not a developer and I don't know what "testsrc" is. I tried to know more about it but I havn't found something useful.
However I tried many other input files (mkv containers or single h264 raw files) that I already have converted successfully using ffmpeg_3.4 but I had no luck using newer ffmpeg versions, so it shouldn't depend of what input file is used.

Please test git current FFmpeg git head, provide the failing command line together with the complete, uncut console output and use git bisect to find the commit introducing the issue.

I'm using pre-built versions on my Windows 10 64 bit because I have no time to set the environment to build it and to use GIT commands.

I just was interested to signal a BUG.

[Antony R]

I already attached a ZIP file containing three UNCUTTED log/report files generated using the "-report" attribute of ffmpeg using v3.4, v4.0 and the last Nightly.

What version of nvidia-drivers are you using, and what version of the nv-codec-headers was your ffmpeg built with?

[Antony R]

Replying to oromit:

What version of nvidia-drivers are you using?

nVidia Drivers: 389.27 WHQL (17 April 2018) updated few minutes ago using Win10 "Device Manager -> Update Drivers" manual procedure.

What version of the nv-codec-headers was your ffmpeg built with?

I don't know.
I just downloaded FFMPEG 4.0 using official download link (​https://ffmpeg.zeranoe.com/builds/) and selecting "Version: 4.0" - "Architecture:Windows 64 bit" - "Linking: Static"

[Timo R.]

There are no official builds, but I assume Zeranoe uses the latest 8.1 headers.
Those require a minimum driver version of 390.77.
Kinda surprised your old drivers report 8.1 support, but clearly don't have it.

Anyway, not an ffmpeg issue. Update your drivers or build ffmpeg with 8.0 headers if you for some reason need older drivers.
