UHD Media Player - 4K Video Player, HDR Stream Inspector & Decode Benchmark
UHD Media Player is a 64-bit high-resolution video player, color metadata
inspector, and real-time decode throughput analyzer for Linux powered by
FFmpeg/libavcodec (PyAV) and QtMultimedia. A Linux alternative to Daum
PotPlayer 64 for 4K UHD playback, color-space inspection, and decode
benchmarking, it decodes real H.264, HEVC/H.265 (8-bit and 10-bit), VP9,
and AV1 media streams on 64-bit Linux systems.
Key Features:
- Up to 4K UHD Decoding: Multi-threaded libavcodec decoding up to 3840x2160
with synchronized 48 kHz stereo PCM audio via QtMultimedia / PulseAudio,
aspect ratio controls, frame stepping, and lossless PNG frame capture.
- HDR & Color Metadata Inspector: Reads real stream color range, matrix
coefficients, color primaries (BT.709 / BT.2020), and transfer functions
(SDR, HDR10 SMPTE ST 2084 PQ, HLG ARIB STD-B67) directly from containers.
- Live Playback Telemetry & Hardware Probe: Displays real-time decoded,
shown, and dropped frame counters, per-frame decode latency (ms), CPU
model from /proc/cpuinfo, and DRM GPU adapters from /sys/class/drm.
- Built-In Decode Benchmark: Measures unthrottled raw video decode speed
(frames/sec) on any opened local media file.
