To get the MX Player custom codec 1.49.0 ARMv8 NEON working, you need to manually link the ffmpeg library to the app's decoder to enable support for formats like EAC3, AC3, and DTS. For version 1.49.0, the app strictly requires the library file to be named libffmpeg.mx.so.neon.1.49.0 or it will fail to load. 1. Download the Correct Codec Pack
For version 1.49.0, you should ideally use the AIO (All-in-One) ZIP pack, as it automatically includes the correct files for ARMv8 NEON and other architectures.
Official Repository: Check the USBhost MX_FFmpeg GitHub for the v1.49.0 release assets.
Third-Party Mirrors: Reliable versions are often hosted on sites like Free-Codecs or WinXDVD. 2. Verify Your Architecture
Before installing, ensure your device actually needs the ARMv8 NEON codec. Open MX Player. Go to Settings > Decoder.
Scroll to the bottom and look at the Custom codec entry. It will explicitly list the required type (e.g., "ARMv8 NEON" or "neon64"). 3. Install the Codec Manually

It sounds like you're trying to add a custom codec (often libffmpeg.mx.so or similar) to MX Player so it can handle more video/audio formats—especially on an ARMv8 NEON device (64-bit).
However, MX Player v1.49.0 doesn't exist as of now (latest stable is 1.46.x, beta 1.47.x).
If you actually have MX Player v1.49.0 (beta/modified), or you just need a working custom codec for ARMv8 NEON, here’s the best approach:
While the stock MX Player works for basic MP4 files, the 1.49.0 ARMv8 NEON codec is non-negotiable for media hoarders. It transforms your phone into a true home theater device, handling DTS-HD audio and high-bitrate 10-bit video without breaking a sweat.
Download it, install it, and finally watch that 20GB BluRay rip on your commute.
