STREAMIX
English

Media server · Players for every platform

Original quality,played natively on your device

STREAMIX has two parts: STREAMIX Server, which only streams and never transcodes, and STREAMIX Player for eight platforms. Every playback is DirectPlay. Decoding, HDR compositing and Dolby Vision all happen on your device.

Principles

Four principles behind both products

  1. The server only streams

    Server sends the original file and serves byte ranges on request. It never transcodes audio or video and never repackages it. What you see and hear is the source itself.

  2. Playback happens on your device

    Hardware decoding, HDR compositing, audio output and Dolby Vision use each platform’s native capabilities. If the device cannot play a format, the app says why instead of spinning forever.

  3. Our own core, consistent everywhere

    All eight platforms share one in-house playback core and engine, so playback and picture handling behave the same everywhere. libmpv and ExoPlayer are fallbacks you can switch to in settings.

  4. Honest labels

    The interface shows which engine is playing and which format is actually being output. A downgraded picture is never presented as the original.

Products

One server, one family of players

Use them together or on their own: STREAMIX Player also connects to your existing Emby and Jellyfin servers.

STREAMIX Player architecture

Our own core, native shells

To give users on all eight platforms the same playback experience, we built our own playback core and engine from scratch and share it across every platform. Around it, each platform gets a native app shell: Qt on Windows and Linux, SwiftUI on Apple, Kotlin on Android. The experience is the same everywhere, and every app still feels at home on its platform.

After you press play

Every playback is a round trip through all seven layers: first the request travels from the screen to the server, then the original file travels back to the screen. Decoding, HDR and audio-video sync all happen on the device.

① Request: from screen to server

  1. L1Native shell

    You press play in the native interface.

  2. L2Interaction

    Playback controls take the action, the same on all eight platforms.

  3. L3Facade

    Cross-language bindings or a C interface hand the request to the core.

  4. L4Core

    The core shared by all eight platforms picks the playback route.

  5. L7Protocol

    Gets the playback address over the Emby, Jellyfin or STREAMIX protocol; credentials stay in request headers.

  6. ServerMedia server

    STREAMIX Server, Emby or Jellyfin starts streaming, without transcoding.

② Playback: the original file back to the screen

  1. ServerMedia server

    Sends the original file, read on demand.

  2. L7Protocol

    Reads the bytes of the original file as needed.

  3. L4Core

    The byte source and cache hand the data to the engine.

  4. L5Engine

    Our own engine splits the file into video, audio and subtitles; libmpv and ExoPlayer are fallbacks.

  5. L6Platform pipeline

    Native capabilities decode in hardware, composite HDR and output sound, with audio as the clock that keeps the picture in sync.

  6. L1Screen

    Shows the picture and labels the engine and output format actually in use.

Where each client stands

Every client is scored on the same nine milestones, totalling 100%. Merged into the main line counts in full, in progress counts half, planned counts nothing. Open a client to see each milestone.

About

STREAMIX began on November 18, 2025

We wanted a private media setup without compromises: the server only sends the original file, and every device plays it back the best way it can, so every screen in your home gives you the best private viewing experience.

  1. Design of STREAMIX begins
  2. Development of STREAMIX Player begins
  3. STREAMIX Server releases its first version, 0.3
  4. Server enters 0.9 release-candidate testing; Player moves forward on all eight platforms
