Advertising a webview-shaped profile (DR-148) was necessary but not sufficient. Probing the server directly showed Jellyfin 10.11.5 enforces a DirectPlayProfile's Container and VideoCodec — excluding either returns SupportsDirectPlay:false with TranscodeReasons=ContainerNotSupported / VideoCodecNotSupported — but ignores its AudioCodec entirely: an E-AC-3 track is still offered for direct play against a profile listing only aac,flac,mp3,opus,vorbis. Neither a VideoAudio CodecProfile forbidding the codec nor MaxAudioChannels:2 against a 6-channel track changes the answer, so no profile the client can send fixes this and the picture plays silent. The client therefore stops delegating a question it can answer itself. The negotiated source's audio is checked against what the webview decodes, and an undecodable track forces the existing h264/aac HLS transcode regardless of the server calling direct play fine; direct_play and needs_transcoding are corrected to match so the frontend and the reporting path agree with the URL actually used. The track judged is the one that would be served — the default, else the first — since a supported track further down is not the one that plays. A source with no audio, or a codec the server did not name, is left alone rather than transcoded on a guess. Test-first: the new tests failed against the old behaviour before the decision existed. Verified on a motorola edge 30 by the audio HAL, not by ear — the same E-AC-3 episode logged isMusicActive=true once and 58 ACDB-LOADER lines under this build, against 0 and 0 on 0.4.6, where an AAC file in the same session produced 16 and 116. No FATAL EXCEPTION, so R8 on the signed release build is unaffected. Also carries in-flight subtitle-track work authored in a parallel session (subtitleTracks, VideoPlayer, player/media, bindings) at the user's request, so the tag matches the APK verified on device.

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
