Hi ... Why is the Infuse app able to use tha AC3 codec (for MKV files) while VLC is not able ?

Maybe you just ask them?

This is fixed with the 2.7.7 update release yesterday morning. Requires an iOS device with an A7 chip (64bit) — in other words: iPhone 5S (or later), iPad mini 2 (or later), iPad Air, iPad Pro or iPod touch 6th Gen.
