They pretty explicitly say that people on x86 or Tegra devices no longer need an additional codec install for MX Player to function at all. Those are available as APKs on the Play Store. ARM devices have always had it included right in the main MX Player APK.
People will still need the add-on codec zips from this thread for supporting DTS, etc. That's a different situation entirely.
So, any chances to have a version working with it!?
