Hi Diego

If slackmedia is based on slackware current, ffmpeg have problems using
the new version of libopenjpeg, ffmpeg only be compiled with version 1.x
of libopenjpeg but slackware uses version 2.1

To solve this problem you can install both librariesat the same time,
but you must modify the SlackBuild of libopenjpeg and rename to

You can use the SlackBuild of libopenjpeg that I have on github[1] and
then compile ffmpeg.
