Well, not quite. I agree there was a little progress toward changing the
injustice introduced with such behavior, but there is one major key
point that should be noted.
"ffmpeg tool" (binary) distributed with debian/ubuntu has been modified
by a third party (either by debian/ubuntu packagers or by libav
developers), so it's not original ffmpeg in any case. The statement
like:
"ffmpeg version 0.8.1-4:0.8.1-0ubuntu1, Copyright (c) 2000-2011 the
Libav developers"
is fraudulent, because that is NOT ffmpeg binary (because the original
ffmpeg binary does not have any such misleading message in its output).
Also, libav developers have created a FORK of ffmpeg, thus they can't
claim the copyright on ffmpeg binary, but only their own, named
"avconv".
Here we have a typical copyright infringement combined with false
advertising, which really is a criminal act, at least according to the
current laws in US.
The entire issue happened because libav developers (some of which are
also part of the debian maintainers group) wanted ffmpeg to just
disappear and go away from the scene. The method they've used is really
immoral and also maybe criminal too. If there is any decency left in
debian/ubuntu community, this issue should be resolved once and for all
in a correct way. Either remove ffmpeg completely, stating the reason
why it was removed (switched to ffmpeg fork named libav) and without
providing any binaries for any kind of "compatibility" and such (take
the responsibility for your actions) or use and modify the avconv binary
and write whatever kind of message you like. Nobody will care in that
way.
Just stop distributing something that is not ffmpeg, claiming it is
ffmpeg, copyrighted by libav and "not developed" or "deprecated"
anymore.

The message that says "This program is not developed anymore and is
only provided for compatibility. Use avconv instead (see Changelog for
the list of incompatible changes)." is simply put a lie. FFmpeg
project is still alive and active (with double the size of user
community than libav, which is simply a fork of FFmpeg project), so
that message should be removed or rephrased to something less
misleading.
People are coming to FFmpeg support channel asking when did FFmpeg
"shut down" and similar crazy stuff, which really annoys more and more
people. I don't know how was this allowed to happen in ubuntu
community, but it is really a bad example for all.
If there are any moral and decent people in ubuntu community left,
this thing should be corrected, because if you leave it this way, it's
simply telling lies to ubuntu users, making them believe something
that is not true. Please fix this.
