## 🌟 Core Architecture & Engineering Highlights

Just Player's design philosophy prioritizes pure video decoding performance, minimal CPU overhead, and native Android framework fidelity.

### Native Google Media3 / ExoPlayer Hardware Core
Rather than bundling heavy, custom-compiled C++ multimedia libraries, Just Player utilizes the latest official **Google AndroidX Media3 / ExoPlayer engine**. Operating directly with native Android MediaCodec hardware video decoders, it offloads 4K and 8K 60FPS video decoding (HEVC, AV1, VP9, AVC) to the device GPU with sub-millisecond initialization latency and near-zero battery consumption.

### Advanced HDR10+ & Dolby Vision (Profile 5, 8, 7) Tone Mapping
Just Player features native support for modern high dynamic range color pipelines. It automatically detects and renders **HDR10, HDR10+, HLG, and Dolby Vision (Profiles 5, 7 MEL/FEL, and 8)** video streams, correctly mapping color luminance to your display's peak nits without washed-out highlights or dark crushing.

### Bit-Perfect Audio Passthrough & Auto Frame Rate (AFR)
For home theater enthusiasts and Android TV boxes connected to AV receivers, Just Player supports **Bit-Perfect IEC Audio Passthrough**. It bitstreams uncompressed **Dolby TrueHD with Atmos, DTS-HD Master Audio, E-AC3, and AC3** streams over HDMI with zero operating system resampling, featuring seamless **Auto Frame Rate (AFR)** display refresh rate synchronization.
