Use binary that fall under LGPL license?

[NordlingDev]

If I read the ffmpeg.exe.LICENSE file, it says that the Ffmpeg is under GPL license. There are two different licenses for Ffmpeg and the one that is less restrictive is the one with LGPL license. Can we decide which one we would like to use? I do not want to release the source code of my project due to a GPL license of Ffmpeg. If I follow the general directions how to bypass this, I should use the LGPL licensed Ffmpeg version.
