Play Unsupported Audio Video Files MX Player

MX Player

With over 500+ Million installations and around 68 Million reviews on Play Store, MX Player has become the most popular audio and video player among Android users.

This application was first released in 2011 by J2 Interactive. For an application that does not come pre-installed on Android mobiles, 500+ Million installations marks a major milestone for the media player as the downloads are 100% user generated.

Despite being acquired by Times Internet (Indian media company) for about $145 Million (Rs. 10,000 crore) and recently introduced full-screen advertisements, MX Player still maintains 4.5 out of 5 stars on Play Store. This proves that this media player is still loved and used by many Android users. I am one among them.

Why MX Player?

As you can see from above information, most of the Android users prefer MX Player over any other Android media player. This is simply because of its user interface (UI) and performance. It even surpasses VLC Media player on some aspects.

MX Player includes support for a wide variety of custom codecs. Thus, it can play any file you can think of (provided it should be a media file) with the help of external/custom codecs.

MX Player has numerous options compared to other media players that makes it superior to them. One can actually tweak MX Player using its settings to optimized playback and to match the hardware of his/her mobile.

MX Player is the most powerful media player that supports all audio formats out there. It is also the first video player that supports multi-core decoding feature. That means you can make use of dual-core of your Android mobile (if it supports) to improve its performance by 70%. Can you believe it?

How many of other media players supports pinch to zoom, zoom and pan on their free versions? MX Player does. Its a full-featured media player but with advertisements. MX Player supports a variety of subtitle formats and lock feature specially for kids.

On top of these features, MX Player supports some pre-defined themes (light, dark, blue etc) which you can choose from and make them default whenever you feel like.

These are some of the features that comes in the free version of MX Player. The only difference in the pro versions is the advertisements. In the pro version, you will experience ad-free media playback.

Even with such features, MX Player still cannot play some media files without the support of external/custom codecs. Following are the reasons for unsupported media in MX Player and instructions to be followed to play unsupported audio and video files in MX Player.

Reasons for Unsupported Media

Most of the current movies and videos available for download online are encoded with DTS / DTSHD / AC3 / EAC3 / MLP audio tracks. And as a hardware/software limitation, most of the Android mobiles cannot play these types of audio tracks. Hence users are unable to listen to the above mentioned types of audio tracks individually or along with the encoded video files.

MX Player too cannot play these types of audio tracks individually or along with encoded videos with its default installation.

Things required to play unsupported audio and video files in MX Player

To play unsupported audio and video files, you need to add custom codec to MX Player. The custom codec is specifically developed for MX Player, so rest assured that you will be able to play above mentioned audio tracks individually or along with encoded video files.

This custom codec contains FFmpeg library. FFmpeg is a multimedia framework which is able to decode, encode, transcode, mux, demux, stream, filter and play most of the multimedia files. The attached custom codec is just a modified version of the FFmpeg library used in MX Player. It’s modified to support DTS and Dolby (ac3) audio tracks.

MX Player Alternative

It is not appropriate to consider MX Player the only customizable media player for Android mobiles. There are some other media players like VLC Media Player for Android that performs pretty well (not better than MX Player) and can be customized too. Most of all, it is free from advertisements. So, if you are too annoyed of advertisements in MX Player, you can either go for a pro version and support the developer or switch to VLC Media Player for Android.

All credit goes to USBhost, the developer of the custom codec, who made it possible for us to play unsupported audio and video files in MX Player.
