I would like to package Mplayer with the ffmpeg modifications that allow it to play DivX videos without non-free code. The upstream code of Mplayer includes OpenDivx which is non-free and I am willing to strip this code from it in favor of the ffmpeg code if the OpenDivx license is not changed soon.
I think that takes care of licensing, but I know that patents are a problem when it comes to DivX. Unfortunately I don't know much detail beyond that. Rules of my home country governing me beside, what patents are problematic and how would it affect my hope to package?
