Hi, everyone:

We are using Ffmpeg library to build up video panel application in small device
Environment. I have the following license options to build up Ffmpeg library:

With or without "-enable-gpl";

According to the introduction from FFMPEG<http://ffmpeg.org/legal.html>, with GPL license, Ffmpeg has
incorporated several optional parts and optimizations.

Does anyone know what those parts are and what changes on the optimizations?

One of the method to get the answer is from source codes, but I would like
to know from your side. If you happen to know any pieces of answers, would
you share those with me.

Thanks a lot!
