Build FFMPEG with NVIDIA hardware accelleration libraries on Debian 12. Includes non-free libnpp!

Obsolete

It is no longer necessary to use this script to have hardware acceleration in ffmpeg on Debian. The default Debian ffmpeg and dependencies now support this out of the box.

An ironic statement, since you're going out of your way to install a bleeding edge package.

Indeed it is, but as said is the only package I have installed this way :)

But I think you meant you don't need other bleeding edge packages. You might want to reflect that in your blog, so users don't think you need to do that.

You are correct I'll update the blog. Thanks for the heads-up
