FFMPEG [h264_nvenc @ 0x56151389fe00] Cannot get the preset configuration: invalid version (15)

i have issue with ffmpeg as usual :D. I have FFMPEG compiled (version N-90807-g00099ef0d0) with NVIDIA support (latest CUDA and latest NV Headers):

Use -h to get full help or, even better, run 'man ffmpeg'

When I try to run basic transcoding on GPU using command:

ffmpeg -i 'udp://@239.100.0.1:331?fifo_size=‎100000000' -map i:0x100 -g 20 -vcodec  h264_nvenc -map i:0x101 -ab 128k -ar 48k -acodec aac -f mpegts udp://@239.0.0.1:1234?overrun_nonfatal_optin=

I got this error:

I have same version of FFMPEG compiled by the same way on another testing machine and there it is working. I tried to recompile/reinstall ffmpeg with the latest version, but result is the same.

Does someone know what could be wrong on my instance? Thanks.

Fixed. The issue was in nvidia headers. Used version was extremely new. If you'll get this issue, just use the headers with tag n8.0.14.1 and then compile ffmpeg. FFmpeg version of headers required to interface with Nvidias codec APIs:

git clone https://github.com/FFmpeg/nv-codec-headers.git
git checkout n8.0.14.1
make && make install
