The was the software solution to this problem. It utilized the phone's CPU (software decoding) rather than the dedicated media chip (hardware decoding). Because MX Player’s implementation of FFmpeg was highly optimized for NEON extensions, it could play video files smoothly that would otherwise crash the system video player.
Tap the (three horizontal lines) in the top-left corner. Go to Settings and select Decoder . Scroll down to the very bottom of the page. Look for the Custom Codec section.
To get the right codec, you need to understand the hardware it's designed for. The "ARMv8 NEON" part of the codec's name refers to your device's processor architecture.
After restarting, the new codec will be active. Your videos with AC3, DTS, or E-AC3 audio should now play correctly. You can verify the installation by going back to > Decoder , where the "Custom codec" option should now show the path to the file you just selected. Mx Player 1.13.0 Armv8 Neon Codec
These core features make the default version of MX Player highly capable. The need for custom codecs like the ARMv8 NEON pack arises not from a flaw in the player, but from the complex and evolving landscape of audio codecs and licensing.

Today, MX Player 1.13.0 with the NEON codec is preserved by archivists and users with older Android TV boxes. It serves as a proof-of-concept that well-optimized assembly code can outperform generic decoders by a factor of 3-5x. While the app itself is outdated, its ARMv8 NEON codec remains a masterclass in low-level mobile optimization. The was the software solution to this problem
This error occurs if you try to use a newer codec (like version 1.49.0) on an older MX Player 1.13.0 installation, or vice versa. Ensure both your player version and codec version match. "Product not compatible"
In the world of Android video playback, MX Player has long been a household name. It's widely celebrated for its powerful hardware acceleration and intuitive controls. However, many users, especially those with modern devices, eventually run into a frustrating problem: silence. Their video plays perfectly but there is no audio. This is often due to the player's lack of support for certain audio codecs, particularly for modern file formats.
For , Mx Player's approach serves as a model for optimizing media applications. It highlights the importance of leveraging hardware capabilities and specialized instruction sets like Neon to achieve performance enhancements. Tap the (three horizontal lines) in the top-left corner
This matches the specific version architecture of your MX Player app. Custom codecs must match your app version family to prevent crashes.
You will see errors like:
