If there are specific interfaces from Libav 10 needed, it would be 
better to directly probe for them.

Furthermore this version check seems to be not very reliable, because 
even if only development packages from FFmpeg (version 2.X.Y) are 
installed, the version is detected as 10.2.

As I don't know why this is the case, or if this behavior will continue 
in the  future, simply removing this version check seems like a good idea.

Best regards,
Andreas
