Choosing the Right MX Player Custom Codec

After the high interest in our previous guide, How to Fix EAC3 Audio Not Supported in MX Player, we thought it’d be helpful to clarify some details about MX Player’s Custom Codecs.

MX Player is a top media player for Android, known for handling a variety of file types with ease.

However, certain audio and video formats may need additional support to play smoothly—and that’s where custom codecs come in.

Custom Codecs extend MX Player’s capabilities, letting it decode a wider range of media formats. Choosing the right codec version for your device is important to ensure smooth playback without taking up unnecessary storage.

Here’s a guide to help you pick the right version.
