To whoever takes care of our facebook page:
Please redirect license questions to the user mailing list.

(How does the application play files back without converting them?)

As Lou wrote, the FFmpeg license does not cover "playback" or
"conversion", it only covers distribution.

You don't "need" a license, FFmpeg can only be legally distributed under
the terms of the LGPL or GPL.
