Yeah I'm awake... here be happy
FFmpeg v4.2 got updated to something
We now have the MX util source. We used to only have the .so file.
Other stuff got updates or so we hope (Too lazy to look more).
This should cover MX Player Pro 1.93.3 and the current free 1.96.x.
The file names are 1.87.0 because baka MX does not know how to change file names.
