DR-237's video half. mpv now renders Windows video the way tauri-plugin-libmpv does on Windows: MpvBackend is handed the main window's HWND and sets it as `wid` before mpv initialises, so mpv draws as a child of the app window beneath the transparent WebView2, with vo=gpu-next,gpu. osc, default bindings, VO keyboard and cursor handling are off, so the Svelte controls drawn over the picture are the only ones. - video_output() decides per platform (UT-274): Window(hwnd) on Windows, RenderApi on Linux, Off without native video. Windows with no handle draws nothing rather than letting mpv open a top-level window. - native_video::enabled() is true on Windows as well, so the frontend takes the native path there: NativePlayerAdapter, and the page clears its background while video is on screen. - enableNativeVideoCompositing() no longer logs a missing Android bridge as an error on the desktop, where there is no bridge to have. Verified: every option, wid included, is accepted by the real libmpv on Linux and by the shipped Windows DLL under wine; the Windows unit suite passes under wine (949). Not yet seen on real Windows hardware.

JellyTau
A cross-platform Jellyfin client built with Tauri, SvelteKit, and TypeScript.
Business logic lives in a Rust backend; a UI-rich Svelte frontend handles presentation and talks to it over Tauri's IPC. Targets Linux (libmpv) and Android (ExoPlayer).
Getting Started
This project uses bun as its package manager.
# Activate the Rust environment (fish shell)
source "$HOME/.cargo/env.fish"
# Install dependencies
bun install
# Run in development
bun run tauri dev
# Type-check the frontend
bun run check
# Build for Linux
bun run tauri build
# Build for Android
bun run tauri android build
For the full set of build, test, and Android helper scripts, see scripts/README.md.

Contributing
CONTRIBUTING.md covers the setup, the gates a change has to pass, and the two rules that catch people out (bug fixes start with a failing test; Jellyfin's taxonomy stays in Rust). Please also read the Code of Conduct.

Verifying a download
Every release publishes SHA256SUMS covering all of its artifacts, plus an SBOM
of what went into the build:
sha256sum -c SHA256SUMS
Desktop builds update themselves from Settings → Updates, verifying each payload against JellyTau's signing key before installing. Android installs are handled by the system installer, so the app links to the releases page instead.
Recommended IDE Setup
VS Code + Svelte + Tauri + rust-analyzer.
