-If you are doing multimedia on Linux, ffmpeg is possibly the most important dependencies to install. Since ffmpeg is a big application with innumerable options, it's best to maintain control over whether these options are enabled or disabled. It is not included in any Slackermedia queue file because the default build script available on Slackbuilds.org is insufficient.

 Since there is an existing SlackBuild script for ffmpeg on [[http://slackbuilds.org]], start with that. Download the components of the package (unless you have already mirrored the entire SlackBuild tree, in which case you should just ''cd'' into the directory containing all of the components) and open the SlackBuild script in the text editor of your choice. Edit the build script include the codec support that you require.

+For each codec that you choose to support in ffmpeg, you need to compile //and install// them prior to compiling ffmpeg.

 Alternately, just build it as provided from SlackBuilds. Most substantial codec support is still opt-in, so the command to start the SlackBuild will look something like this:

+The list is very long; it's basically impossible to include everything, so look through the codecs listed, install what you think you might need, and then build ffmpeg.
