As Herv? W. already pointed out, this license version also allows
conversion to any version of the GPL. And this idea would have no chance
of working anyway: if the earlier version of the license did have
different requirements then specifying "the earlier version and no
later" would be incompatible with the rest of FFmpeg which specifies
"2.1 or later".

LGPL allows conversion to any version of the GPL, but the GPL does not.
Neither GPL 2 nor GPL 3 allows conversion to a later version as an
integral part of the license itself. The right to use under "version X
of the License, or (at your option) any later version" is given (or not)
