thanks, this will make my life easier in next ffmpeg changes!

damn, bad me :)
I thought the version was the same, they were just three defines pointing to the same
number (bad me that I didn't check that, and I remember that they are different when I install
the packages, one is 56, one 54 and one 53, bad me twice)

I fixed this, and now it is building correctly :)
>Yes, these changes are safe:

then I'll upload as soon as the previous one reach testing.

thanks again, for the great help, in the future I'm sure I'll be able to try to fix this mess
by myself (the first step is alwasy the biggest one)

cheers,
