Mx Player Pro Codec Armv8 Neon (BEST — Choice)

As of late 2025, the answer is yes. While Android has moved to Armv9 (which focuses on security and machine learning), it retains full backward compatibility with Armv8 NEON instructions. The big change is Android’s gradual deprecation of 32-bit app support (from Android 14 onward). This actually secures the Armv8 NEON codec’s future—because 64-bit is now mandatory, the codec will remain relevant.

However, note that VLC for Android and Kodi include AC3/DTS decoders out-of-the-box using FFmpeg libraries. While those are excellent alternatives, they lack the hardware-accelerated touch gestures and lightweight nature of MX Player Pro. For the foreseeable future, power users will continue to pair MX Player Pro with the Armv8 NEON custom codec.

Use a test file known to require the codec (e.g., AC3 5.1 audio).
In MX Player: Mx Player Pro Codec Armv8 Neon

  • Check audio track info: Menu → Tools → Properties → Audio codec should show ac3 or dts.

    • If audio is still missing → Go to Settings → Decoder → tick Enable HW+ audio and Use software audio as fallback.

    To understand the necessity of the specific codec, one must first understand the hardware. Since approximately 2014, the vast majority of Android smartphones and tablets have transitioned from 32-bit to 64-bit processors based on the ARMv8 architecture. This includes chips from Qualcomm (Snapdragon), Samsung (Exynos), MediaTek, and Huawei (Kirin). As of late 2025, the answer is yes

    Integrated into these ARMv8 processors is a technology called NEON. NEON is a 128-bit Single Instruction Multiple Data (SIMD) architecture designed specifically for media processing. In simple terms, NEON allows the CPU to process large chunks of audio and video data in parallel rather than sequentially. This is critical for high-resolution video decoding, especially for codecs like HEVC (H.265) or VP9.

    If the official codec doesn’t enable certain formats (e.g., TrueHD, MLP), consider FFmpeg for MX Player (unofficial).
    But note: It may break HW+ decoding and reduce performance. Check audio track info: Menu → Tools →

    Only use if you understand the trade-offs.
