One fix since v0.11.4: a video in a picture-in-picture window no longer drops to audio-only partway through, replaying from wherever the picture had been when the window opened. Two independent faults had to line up for it. The player's position variable is written only by a requestAnimationFrame loop while playing, and RAF stops for a document that is not being rendered -- which an Android activity behind a PiP window is not; the `timeupdate` handler that would have covered the gap had gated itself on `!isPlaying` since the first commit. And PiP and the background-audio handoff, nominally alternatives, could both be armed at once, with a single `isInPictureInPictureMode` sample taken inside onStop() standing between them. The frozen position was not confined to the handoff: the seek bar, resume points and the progress reported to Jellyfin all read the same variable, so all three stood still for as long as a PiP window was open. Version stamped with scripts/set-version.sh. defect-windows.md records DR-265 under the present-since/reachable-since gap: defective since v0.0.1, but only hittable once PiP started working on the HTML5 path in v0.5.3.

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.
