WTF - ffmmpeg even displays the configure string and so you have all 
informations how it was built

"which includes the objects that linked against" is nonsense, when YOU 
LINK against some GPL sourced libs you need to provide YOUR source - 
caus and affect inverted by you

and with "According to LGPL / GPL" you clearly show you have no idea 
what you are talking about, otherwise you would know the differences of 
both and that you can link against LGPL libraries without release youzr 
sources under the same license

*jesus christ* ffmmpeg is linked against tons of other libraries and you 
are inverting the intention of the GPL
