The media-autobuild_suite adds some out-of-tree patches on top of 
ffmpeg, so its version number is non-standard.

However, it can still be deciphered.

N indicates that the build is of the master branch of ffmpeg.

100471 is the commit count. See the number on the blue bar just above the file listing at https://github.com/FFmpeg/FFmpeg

The 2nd g-prefixed hash - g5b48d2af43 identifies the latest ffmpeg commit at time of building.

It can be viewed at https://github.com/FFmpeg/FFmpeg/commit/5b48d2af43

+1 represents the number of out-of-tree commits applied on top.
