Is that so? Then I refuse to answer publicly. ;-)

ffmpeg-2.2.1 is most certainly not ffmpeg-3.1.2!

Once they are resolved, it is still not ffmpeg-3.1.2.

Anyway,

That is most certainly an ffmpeg-php issue. Have you considered asking
their developers? ffmpeg-php is not maintained by ffmpeg.

Considering that ffmpeg-php-0.6.0 is eight years old, it is most likely
incompatible with recent ffmpeg libraries. You need to find something
which supports current ffmpeg. (There's even a note an the ffmpeg wiki,
all the way at the bottom of this section:
https://trac.ffmpeg.org/wiki/PHP#WrapperLibraries)
