Each of these was invisible while Linux video played in the webview, and each became reachable the moment mpv started rendering. DR-238 — a transcoded seek re-negotiates the stream on every renderer, not just the webview. `determine_video_seek_strategy` treated `is_hls` as a proxy for "seekable in place", which held only because hls.js was always the HLS renderer: it seeks within the VOD playlist it is handed and lets the server catch up. mpv's HLS demuxer cannot make Jellyfin transcode from a new offset, so with native video on, every transcoded seek became a backend seek that silently did nothing. One cell of the truth table changes; all four webview cells are byte-identical. DR-239 — properties the mpv event loop handles are now observed. libmpv delivers PropertyChange only for properties registered with observe_property, so the `pause` arm was unreachable code that read as implemented: StateChanged was never emitted and the play/pause control never moved. UT-218 asserts the two lists agree, so the class cannot recur. DR-240 — fullscreen moves whatever owns the pixels. requestFullscreen() fullscreens the *document*, which sufficed while the <video> element lived inside it and WebKit scaled it. A native surface is drawn behind the webview at window size, so a document-only fullscreen expanded the page and left the picture at its old size — on WebKitGTK, a maximised window with decorations still holding a strip of the screen. Measured on a 3440x1440 panel: 1361 tall before, 1440 after. DR-241 — a seek issued before mpv has a file to seek in is honoured rather than dropped. loadfile returns as soon as the command is queued, so `time-pos` does not resolve yet and setting it fails. The two callers that always hit that window are resume and a transcoded seek, both of which re-open the stream and then ask for a position; the failed seek was discarded and playback began at zero. Also adds the instrumentation that made the diagnosis possible rather than speculative: an entry log on player_stop, a render-size log that re-fires on change instead of latching once, and decoded-vs-display video geometry on file load. The last of those retired a wrong theory — a picture that does not fill an ultrawide turned out to be a 16:9 source with its letterbox baked in, not a rendering fault.
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.
