Modules

auth 🔒

storage 🔒

Offline storage module using SQLite

thumbnail 🔒

Thumbnail caching with LRU eviction

utils

Structs

BackendInitError 🔒

Payload emitted to the frontend when a native player backend fails to initialize and the app falls back to a no-op backend.

Functions

build_log_plugin 🔒

Cached thumbnails are handed to the webview as asset-protocol URLs by convertFileSrc (asset://localhost/… on Linux/macOS, http://asset.localhost/… on Windows/Android). Tauri only answers that origin when the protocol-asset cargo feature is compiled in and app.security.assetProtocol.enable is set in tauri.conf.json. Both are required together: with either missing the URL resolves to nothing and the webview reports NETWORK_NO_SOURCE, which is how offline video came to fail silently.

create_player_backend 🔒

Create the appropriate player backend for the current platform.

emit_backend_init_failed 🔒

Log a backend-initialization failure and notify the frontend, so the UI can surface “playback unavailable” instead of the app hard-crashing.

enable_linux_hardware_video_decoding 🔒

Configure GStreamer (the media backend behind WebKitGTK’s HTML5 <video> element on Linux) to prefer hardware-accelerated VAAPI decoding when the host provides it, falling back to software decoding otherwise.

log_available_vaapi_decoders 🔒

Probe (via gst-inspect-1.0, which ships with GStreamer) which VAAPI hardware video decoders GStreamer can actually load on this host, and log the result so it is clear at startup whether hardware decoding is genuinely available or whether playback will fall back to software.

run

set_env_if_unset 🔒

specta_builder 🔒

Construct the tauri-specta command builder. Shared by run() and the bindings-export test so the TypeScript bindings always match the handler.
