Download libvorbis, libtheora, libspeex and libogg from, and compile and install them.

Install libogg, libvorbis, libtheora and libspeex

Move into the installation directory then build, configure and install:ģ.You should also run this command after installing libraries. This command updates the dynamic linker's cache of library locations.

If /etc/ld.so.conf does NOT contain the line 'include ld.so.conf.d/*.conf' then add these lines to the end of /etc/ld.so.conf instead of creating a seperate /etc/ ld.so.conf.d/nf file. If you are installing on a 64-bit version of Linux ('uname -m' command returns 'x86_64') then add another line containing '/usr/local/lib64' as well. If /etc/ld.so.conf contains the line 'include ld.so.conf.d/*.conf' then create a file called /etc/ld.so.conf.d/nf containing the line '/usr/local/lib'. If it already contains the line '/usr/local/lib' then the library search path is already OK so please skip to the next section. View /etc/ld.so.conf using 'more' or 'less'. Some distributions include /usr/ local/lib in the dynamic library search path by default but some do not (notably Red Hat). You may need to edit /etc/apt/sources.list to add add:īecause you will be installing libraries into /usr/local/lib you need to make sure that the dynamic linker (ld.so) looks in /usr/local/lib when it is searching for libraries. For example, on Debian you can install them using app-get install libmp3lame-dev libvorbis-dev libtheora-dev libx264-dev libspeex-dev yasm. You may not need to install the libraries and programs that ffmpeg needs (lame, libx264, libvorbis, libtheora, libspeex and yasm) from source - you may be able to install using your package manager.We have also provided specific instructions for Debian GNU/Linux which we recommend that you use if you are running Debian or Ubuntu LTS These instructions may need to be varied for different versions of Linux.Ffmpeg will be installed into /usr/local/bin The required libs will be installed into /usr/local (/usr/local/lib /usr/local/bin etc).The following instructions explain how to install Ffmpeg and required libraries from source (and so they require a compiler such as gcc). For Asset Bank to be able to create thumbnails and previews for video and audio files Asset Bank uses Ffmpeg.
