Bug#1059339: nv-codec-headers: Version mismatch with nvidia-driver package

["Tim H." <dbugs1@cpu0.net>]

Source: nv-codec-headers
Version: 12.1.14.0-1
Severity: important

Dear Maintainer,

After I updated FFmpeg to version 7:6.1-5 hardware accelerated encoding
via h264_nvenc stopped working.

FFmpeg reports:
Driver does not support the required nvenc API version. Required: 12.1
Found: 12.0

[1] states that the minimum required nvidia driver version to support
nvenc 12.1 is 530.41.03 or higher. Yet the most recent version
available in trixie is currently 525.147.05-1.

I managed to compile FFmpeg against an older version (12.0.16.1) of the
headers which fixed the bug for me. Please note that my graphics card
is quite old (NVIDIA Corporation GM206 [GeForce GTX 960]), so I'm not
sure if this bug affects people with more up to date cards.
