Restart MX Player. Play a 1080p H.264 video. Tap the top right corner to see the decoder status. You should see HW+ (Hardware Plus) highlighted in blue. If you see "SW" (Software), the Neon codec failed to load.
To understand the codec, one must first understand the silicon it was designed for. ARMv7 is a 32-bit processor architecture that powered the majority of smartphones from the 2010s, including iconic chips like the Qualcomm Snapdragon S4, the Texas Instruments OMAP4, and Samsung’s Exynos 4412. However, the true differentiator was the NEON SIMD (Single Instruction, Multiple Data) engine.
NEON is a 128-bit vector processing extension built into ARMv7 chips. It allows the processor to perform the same mathematical operation on multiple pieces of data simultaneously. For video decoding—a task that involves repetitive calculations on millions of pixels—this is transformative. Where a standard ARMv7 processor might struggle to decode a 720p H.264 video in real time, a NEON-optimized decoder can offload these parallelizable tasks, drastically reducing CPU load and battery consumption.
