+The FFmpeg version of Nvidia Codec SDK headers which are required
+to interface with Nvidia's codec APIs. The purpose of these
+headers is to allow hardware (GPU) encoding with suitable NVidia
+cards. This version corresponds to Video Codec SDK version 8.1.24.
+
+There are 3 stages of the history of NVidia GPU encoding with FFmpeg:
+
+ 1. Pre August 27th 2016 it was necessary to track down your own
+ headers to build nvenc.
+ 2. Post August 27th 2016 the required headers were incorporated
+ as part of the FFmpeg source.
+ 3. Post February 26th 2018 the NVidia headers were removed from
+ the FFmpeg source. A separate git repository was created to hold
+ continuing work with these headers.
+
+This nv-codec-headers script is for point 3 where the headers will
+need to be installed before compiling FFmpeg.
