Firstly this “https://git.videolan.org/git/ffmpeg/nv-codec-headers.git” url doesn’t exist, secondly when i am configuring the ffmpeg and make -j8 then

It does exist.

https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git;a=summary

This shows https://git.videolan.org/git/ffmpeg/nv-codec-headers.git is the url for the git subprotocol

@val.zapod.vz okay i got it, can you tell me after see above error what could be the possible reason that i am missing.
Error coming when i am build the ffmpeg for gpu acceleration.

You need to use sdk/12.1 branch which has pixelBitDepthMinus8
