Investigation into unifying the playback backends (Linux/MPV, Android/ExoPlayer, Windows/webview) onto one engine with hardware acceleration. Conclusion: video cannot be unified onto a native engine; audio can. The blocker is not mpv-specific. WebKitGTK, WebView2 and Android WebView each draw into their own compositor surface, so a native video surface sits either entirely above or entirely below the webview and cannot interleave with HTML. GStreamer and libVLC fail identically. mpv would additionally regress streaming: it has no adaptive bitrate, while the current hls.js path does. Six specs added: - playback-backend-unification: the analysis and decision, with evidence - android-audio-settings-parity: set_audio_settings on ExoPlayerBackend - android-native-video-spike: timeboxed test of SurfaceView compositing - windows-native-audio-backend: replace the webview <audio> shim with libmpv - libmpv2-migration: dead libmpv git pin -> libmpv2, plus a LICENSE file - playback-docs-corrections: the requirement-status fixes applied here Corrections to requirements.md, all verified against source: - UR-031/DR-034 claimed crossfade was "Done (Linux only)". It is implemented nowhere (mpv_backend.rs has a bare TODO) and is architecturally blocked on mpv, whose single-stream audio chain cannot feed acrossfade's two inputs. - Parity matrix listed crossfade as a Linux/Android gap; it is neither. - The matrix omitted the equalizer, which has the same Linux-only shape. - The suggested ConcatenatingMediaSource is deprecated in current Media3. nativeAdapter.ts cited tauri#10152 as an upstream blocker for native Android video. That issue is a stale feature request, dead since 2024-07-01; the capability shipped in tauri 27d01834 (2024-09-02), and the related black-screen bug was fixed in wry 0.39.4 (we ship 0.55.x). What is genuinely unproven is SurfaceView-behind-WebView compositing, which the spike now tracks.

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.
