Jellyfin's MediaStream.Index is global across every stream in a media source, so index 0 is the video stream on virtually all files. We sent AudioStreamIndex=0 as "the first audio track" on the HLS transcode URL, the background audio-only handoff URL, the direct-play fallback URL and the PlaybackInfo negotiation body — asking the server to use the video stream as audio. Servers that honour it produce a picture with no sound; only those that silently correct the index hid the bug, which is why it surfaced as "some videos have no audio". Omit the parameter unless a track was actually chosen, so the server resolves the source's DefaultAudioStreamIndex. An explicit selection from player_switch_audio_track still passes through unchanged. Dropped outright from the static=true direct-play URL, which serves the original file untouched.

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.

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
