Hi ,

I have installed the nvidia-cuda-toolkit and nv-codec-headers. Attached latest configuration file for reference  please find below screenshot for reference.

Below are the steps which I had followed during  ffmpeg on the the vm by following steps present in the link
1.Downloaded repository "https://git.ffmpeg.org/ffmpeg.git and cloned with

  *   git clone https://git.ffmpeg.org/ffmpeg.git"
2.Downaloded the nvidia driver for tesla T4 product and linux 64-bit RHEL 8
   file name is "nvidia-driver-local-repo-rhel8-510.47.03-1.0-1.x86_64.rpm"
3.Downloaded the cuda tool kit for centos 8 system by running following commands

(I)wget https://developer.download.nvidia.com/compute/cuda/11.6.2/local_installers/cuda-repo-rhel8-11-6-local-11.6.2_510.47.03-1.x86_64.rpm
(II)sudo rpm -i cuda-repo-rhel8-11-6-local-11.6.2_510.47.03-1.x86_64.rpm
(III)sudo dnf clean all
(IV)sudo dnf -y module install nvidia-driver:latest-dkms
(V)sudo yum install cuda

4.cloned the rep FFmpeg/nv-codec-headers

  *   git clone https://github.com/FFmpeg/nv-codec-headers.git

5.After completion of ffmpeg/nv-codec-headers,i have entered to the nv-codec-headers

  *   cd nv-codec-headers
  *   yum install nv-codec-headers
6.Ran the "make install" command and I have got below messages.

[root at localhost nv-codec-headers]# make install
sed 's#@@PREFIX@@#/usr/local#' ffnvcodec.pc.in > ffnvcodec.pc
install -m 0755 -d '/usr/local/include/ffnvcodec'
install -m 0644 include/ffnvcodec/*.h '/usr/local/include/ffnvcodec'
install -m 0755 -d '/usr/local/lib/pkgconfig'
install -m 0644 ffnvcodec.pc '/usr/local/lib/pkgconfig'

7. I ran the the following lines in the terminal one by one

  *   sed 's#@@PREFIX@@#/usr/local#' ffnvcodec.pc.in > ffnvcodec.pc
  *   install -m 0755 -d '/usr/local/include/ffnvcodec'
  *   install -m 0644 include/ffnvcodec/*.h '/usr/local/include/ffnvcodec'
  *   install -m 0755 -d '/usr/local/lib/pkgconfig'
  *   install -m 0644 ffnvcodec.pc '/usr/local/lib/pkgconfig'

Your log file says:
