–

I have to say, that the video manipulation
program FFmpeg, while very powerful, is not very user-friendly when it
comes to installation. While many Linux programs can be happily
installed from either a pre-compiled package, or downloading source and
compiling yourself, this isn’t necessarily the case with FFmpeg. The
ease of FFmpeg installation largely depends on how many different video
codecs and containers you want to be able to input or output. The
greater the number, the exponential increase in installation
difficulty. My main need was for FFmpeg to accept a wide range of input
formats, while outputting H.264 encoded QuickTime (MOV) files. Here’s
how I achieved this on a Debian Etch server……..

I’m going to assume that you are familiar with using the Linux
command prompt, moving between directories, editing text files and have
at least some experience compiling programs.

The first thing I would recommend doing is making an addition to your source repository lists.

pico /etc/apt/sources.list

Add the following line:

deb http://www.debian-multimedia.org stable main

This repository contains some essential libraries for xvid and
x264 (an open source H.264 codec) amongst other things. You’ll need to
install some software from here. The software may well be available
from other repositories too, that are already in your sources.list
file, but add this one to be safe.

Next rebuild your sources:

apt-get update

I would also recommend installing checkinstall. This program can
be used instead of a regular “make install” command and produces a deb
package file that will make re-installation or multiple machine
installs much easier. If checkinstall isn’t already on your machine
download it from:

http://www.asic-linux.com.mx/~izto/checkinstall/download.php

Maybe navigate here with lynx, maybe use wget once you’ve found
the actual file you need, maybe download it with a GUI based web
browser and then copy it to your desired directory. It’s your choice. I
grabbed the latest .deb package. After the download, execute the following as root:

dpkg -i checkinstall_1.6.1-1_i386.deb

Checkinstall should have happily installed on your system. Now it’s time to really get into FFmpeg.

Build the dependencies:

apt-get build-dep ffmpeg

Next we’re going to install a whole lot more useful software
that will allow FFmpeg to output many more than just the minimal file
types.

apt-get install liblame-dev libfaad-dev libfaac-dev
libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev
build-essential subversion,

We’ve also ensured that you have the necessary tools installed
to compile from source (build-essential) and obtain files from the Subversion version control repositories.

We’re ready to checkout FFmpeg itself:

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg,

At the time of writing the latest revision was 11212. If you’d
feel more comfortable not using the lastest bleeding edge version of FFmpeg, issue the Subversion command as follows:

svn checkout -r 11212 svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

This will ensure that you are also downloading the 11212 revision. Once downloaded, move into the ffmpeg directory (cd ffmpeg) and configure:

./configure –enable-gpl –enable-pp
–enable-libvorbis –enable-liba52 –enable-libdc1394 –enable-libgsm
–enable-libmp3lame –enable-libfaad –enable-libfaac –enable-pthreads
–enable-libx264 -enable-libxvid –enable-shared

So, what have we done here……

• gpl – allow use of GPL code, the resulting libav* and ffmpeg will be under GPL
• pp – enable GPLed postprocessing support
• libvorbis – enable Vorbis encoding via libvorbis (
  http://www.vorbis.com/
  )
• liba52 – enable GPLed liba52 support (
  http://liba52.sourceforge.net/
  )
• libdc1394 – enable IIDC-1394 grabbing using libdc1394 and libraw1394 (
  http://sourceforge.net/projects/libdc1394/
  )
• libgsm – enable GSM support via libgsm (
  http://packages.debian.org/testing/sound/libgsm-tools
  )
• libmp3lame – enable MP3 encoding via libmp3lame (
  http://lame.sourceforge.net/download.php
  )
• libfaad – enable FAAD support via libfaad (
  http://www.audiocoding.com/faad2.html
  )
• libfaac – enable FAAC support via libfaac (
  http://www.audiocoding.com/faac.html
  )
• pthreads – use pthreads (
  http://en.wikipedia.org/wiki/POSIX_Threads
  )
• libx264 – enable H.264 encoding via x264 (
  http://www.videolan.org/developers/x264.html
  )
• libxvid – enable Xvid encoding via xvidcore, native MPEG-4/Xvid encoder exists (
  http://www.xvid.org/
  )

The essence of his information, and many more options, can be found by typing ./configure –help first.

(You might also consider including libtheora in your configuration, but I forgot at the time)

We’re now ready to make the installation files so at the command prompt:

make

If something goes wrong, and you need to start again, a useful command to know is:

make distclean

Make sure you do this first and then run the configure command again.

A finally:

checkinstall

You will be asked a few questions, which should be
straightforward enough to answer – yes to creating the documentation,
choose a name, select D for Debian package, lastly select number 3 and
type a version name that means something to you. Mine was
svn11212-etch-20071213. Checkinstall will now create a Debian package
of FFmpeg, bespoke for your system with the configuration options
you’ve selected earlier. Checkinstall WILL NOT install the package, so
don’t forget to do that:

dpkg -i ffmpeg_svn11212-etch-20071213-1_i386.deb

With some small amount of luck, you should now have a working
version of FFmpeg installed on your Debian Etch server. You will be
able to output H.264 encoded files in a variety of containers.

Now the fun part really begins as you spend days tinkering with
commands to output the best possible files. Documentation for using
FFMPEG can be found at:

Have fun!
