14.04 - Why does installed version differ than what apt-cache madison indicates? - Ask Ubuntu


i installed ffmpeg on ubuntu 14.04 lts server. when run ffmpeg -version output is:

ffmpeg version n-81995-gd790e48 copyright (c) 2000-2016 ffmpeg developers

i installed version following commands:

sudo add-apt-repository ppa:mc3man/trusty-media sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ffmpeg

i told following command can used see version of binary/lib apt-get install:

apt-cache madison <name_of_binary>

but when run apt-cache madison ffmpeg on ubuntu server, output is:

ffmpeg | 7:3.1.4+git1~trusty | http://ppa.launchpad.net/mc3man/trusty-media/ubuntu/ trusty/main amd64 packages

i'm wondering why i'm seeing version difference between these 2 commands. why ffmpeg -version version n-81995-gd790e48, yet other command states 7:3.1.4+git1~trusty version should getting installed?
