For Asset Bank to be able to create thumbnails and previews for video and audio files Asset Bank uses Ffmpeg (http://ffmpeg.mplayerhq.hu).

The following instructions explain how to install Ffmpeg from source (and so they require a compiler such as gcc). Please note:

• Ffmpeg will be installed into /usr/local/bin
• These instructions are specifically for version 8.0 (Jessie) of Debian GNU/Linux. Use these instructions instead if you are using another GNU/Linux distribution.

1. Configure APT to use the deb-multimedia repository

Note: the commands in this section must be run as root

1. 1.1) Add the following to the bottom of /etc/apt/sources.list:

   deb http://www.deb-multimedia.org jessie main non-free
   deb-src http://www.deb-multimedia.org jessie main non-free
   

2. 1.2) Refresh apt's package database, by typing:

   apt-get update

3. 1.3) Allow apt to trust deb-multimedia's key, by typing:

   apt-get install deb-multimedia-keyring

4. 1.4) Refresh apt's package database again, by typing:

   apt-get update

2. Remove ffmpeg Debian package

Note: the commands in this section must be run as root

1. 2.1) Remove the ffmpeg package, if it is installed, to avoid confusion caused by having two versions of ffmpeg installed and potential conflicts with the packages that will be installed in the next step:

   apt-get remove ffmpeg

3. Install Libraries

Note: the commands in this section must be run as root

1. 3.1) Install library packages and build tools:

   apt-get install build-essential libmp3lame-dev libvorbis-dev libtheora-dev 
   libspeex-dev yasm pkg-config libfaac-dev libopenjpeg-dev libx264-dev

4. Install Ffmpeg

Note: we recommend that the commands in this section are run as a non-root user (although they should still work if run as root)

1. 4.1) Download and extract the ffmpeg source code:

   mkdir software
   
   cd software
   
   wget http://ffmpeg.org/releases/ffmpeg-2.7.2.tar.bz2
   
   cd ..
   
   mkdir src
   
   cd src
   
   tar xvjf ../software/ffmpeg-2.7.2.tar.bz2

2. 4.2) Move into the source directory:

   cd ffmpeg-2.7.2

3. 4.3) Configure, build and install:

   ./configure --enable-gpl --enable-postproc --enable-swscale --enable-avfilter --enable-libmp3lame 
   --enable-libvorbis --enable-libtheora --enable-libx264 --enable-libspeex --enable-shared 
   --enable-pthreads --enable-libopenjpeg --enable-libfaac --enable-nonfree
   
   make
   
   sudo make install

4. 4.4) Run "/sbin/ldconfig" as root.
