One of the most popular video player on Android is MX player which many people use to watch movies and web series offline. It has currently 100+ crore downloads worldwide and free to use video player and OTT app. This app has a long legacy and still it encounters with costume codec issues.

It has been reported by many users on social media forums that when we download a movie or TV show episode and play it in MX Player. The video plays but there’s no sound at all. Or the player displays an error message, “EAC3 audio format not supported.” This ruins the mood and here users often look for other alternatives! But wait… this problem has a  reliable and permanent solution which I will let you in this article in detail shortly. So be with me and checkout how to fix custom codec issue in the latest version of MX player for free!

Reason Why MX Player Custom Codec Appears?

This problem of custom codec in MX Player primarily arises due to licensing. While it is a great video player cum OTT app, it can’t include advanced audio codecs like Dolby Digital (AC3), EAC3, and DTS in its official version because their licenses are too expensive. Therefore, whenever you play a video with audio encoded in these codecs, the player fails to recognize it and displays an error. This isn’t a flaw in the app, but rather a technical limitation.

Solutions to Fix MX Player Custom Codec

To fix the missing codec issue in MX player, a tool called “MX Player AIO Zip” has been created. The word AIO stands for “all-in-one”… means it is a kit that contains the necessary components for every type of device that we use in real world. Essentially, it’s a zip file or add-on containing custom codec libraries for various Android devices, such as phones and tablets with different processors like Snapdragon, MediaTek, Exynos, Tensor, Unisoc. This package was developed by the community and includes a powerful library called FFmpeg, which gives MX Player the ability to decode these license-restricted audio formats.

The biggest advantage of using MX Player AIO Zip is that you don’t have to bother detecting your phone’s processor. You simply download and install this one zip file, and MX Player automatically selects the appropriate codec (FFmpeg, LAME, libusb, libsmb2, FriBidi)  for your device. This way the issue of custom codec is fixed in the MX video Player app!

How to install MX Player AIO Zip?

1. First, you need to download this AIO zip file from a trusted source. Keep in mind that its latest version as of November 2025 is 1.87.0. Download it only from trusted websites like GitHub or click here.
2. There’s no need to extract the zip file after downloading.
3. Now, open the MX Player app. Within the app, go to Settings, then the ‘Decoder’ section. Scroll down and you’ll see the ‘Custom Codec’ option.
4. Just tap on it, if your player is intelligent, it will automatically find the zip file in your Downloads folder and offer to install it. All you have to do is tap OK. If not, you can manually go to that folder and select the zip file.
5. That’s all… now restart the app or restart the phone!

Once restarted, the magic is done. Now play the same video file on your device that previously had no sound. This time you’ll notice crisp, clear, and authentic sound coming from your speakers or headphones. The process to fix the custom codec works almost identically on both the Pro and Free versions of MX Player, although the path to save the file may differ slightly. This is permanent solution and it works on all Android devices – 100% result!

Final Words

So while using the MX player, if you ever encounter with custom codec issue then simply download the AIO zip file from the trusted source and install it in your device using MX player (go to Settings > Decoder > Custom options) as we have explained step by step above!

Apart from that, if you recently installed a new version of MX Player, such as 2.2.1 or later, it may have native support for the AC3 codec. However, formats like EAC3 and DTS will still require this custom codec. Therefore, if you want a robust solution that will work for all future videos, installing AIO Zip is the best option.
