I don't get it... On my system (Linux Mint 13) ffmpeg, ffmpeg-doc and ffmpeg-dbg 4:0.8.4-0ubuntu0.12.04.1 are transitional packages to Libav things, not to real ffmpeg
and after writing ffmpeg command in terminal first it writes:
*** THIS PROGRAM IS DEPRECATED ***
This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.
I want install ffmpeg package not Libav one. Cause I don't want ffmpeg command used by me to be removed 'in some future release... Is there any method doing this (without messing with compiling)... ;-(
