NexPlayer

The problem

Media players fall into two camps. Lightweight ones play files and offer nothing for working with the audio. Professional audio tools do real signal processing but are not built for simply watching or reviewing footage. Anyone reviewing material and shaping its sound ends up running both.

The approach

NexPlayer is a player with a real-time DSP chain built in. Video decoding is hardware-accelerated through FFmpeg and rendered via OpenGL or Metal, while audio runs through a six-stage effect chain in the same application. The effect chain is modular, so stages are independent units rather than fixed features.

What it does

Hardware-accelerated playback

Video decoding through FFmpeg with rendering via OpenGL on Linux and Windows and Metal on macOS.

Six-stage audio effect chain

EQ, reverb, delay, compressor, flanger and phaser, applied in real time during playback.

Review controls

Frame-stepping, variable playback speed, loop regions and screenshot capture.

Themed interface

Qt Quick interface with dark and light modes and a customisable accent colour.

Genuinely cross-platform

One Qt 6 codebase builds for macOS, Linux and Windows via CMake.

Pricing

Free and open source.
