The ffmpeg program is only provided for script compatibility and will be removed
in a future release. It has been deprecated in the Libav project to allow for
incompatible command line syntax improvements in its replacement called avconv
(see Changelog for details). Please use avconv instead.

A lawyer would notice and give due weight to the terms
"ffmpeg program" and "Libav project", whereas a user might
assume from this output that there's some sort of evolutionary
transition in progress, might they not.

2.3.5. Multimedia
Debian wheezy comes with improved multimedia support: ffmpeg has been
replaced by the libav fork (libav-tools), which is considered to
feature a more conservative release process and thus fit better to
Debian's needs. It provides all libraries and prepares an upgrade path
for existing application packages. The full-featured libav libraries
and frontends include e.g. mplayer, mencoder, vlc and
transcode. Additional codec support is provided e.g. through lame for
MP3 audio encoding, xvidcore for MPEG-4 ASP video encoding, x264 for
H.264/MPEG-4 AVC video encoding, vo-aacenc for AAC audio encoding and
opencore-amr and vo-amrwbenc for Adaptive Multi-Rate Narrowband and
Wideband encoding and decoding, respectively. For most use cases,
installation of packages from third-party repositories should not be
necessary anymore. The times of crippled multimedia support in Debian
are finally over!
I have downloaded
https://www.debian.org/releases/stable/i386/release-notes.en.pdf
to see if there's any mention of ffmpeg/libav but I didn't see any in
"Issues to be aware of for jessie" or
"Hrrtdr sn ad ÃvÃqd ne enq idrrhd" as the PDF puts it!
(Do you all see the headings written in ROT-1?)
Cheers,
David.
