The LGPL does not require you to publish the sources of 
your application if it is linked against FFmpeg, but note 
that you absolutely have to follow the LGPL if you choose 
to distribute binaries based on FFmpeg.

Note that it does not matter at all if you want to sell 
your application or want to give it away for free.

Please do read both http://ffmpeg.org/legal.html and the LGPL

You cannot pay for a different license because there are many 
copyright holders, and many copyright holders cannot be easily 
reached.

Please do not top-post, it is considered rude.
