Struct OnlineRepository 

pub struct OnlineRepository {
    http_client: Arc<HttpClient>,
    server_url: String,
    user_id: String,
    access_token: String,
    connectivity: Option<ConnectivityReporter>,
}

Online repository - fetches data from Jellyfin server via HTTP

Fields

http_client: Arc<HttpClient>

server_url: String

user_id: String

access_token: String

connectivity: Option<ConnectivityReporter>

Reports the outcome of every server request to the connectivity monitor. This is the source of truth for the offline/online banner. None in tests / contexts where connectivity tracking isn’t wired up.

Implementations

impl OnlineRepository

pub fn user_id(&self) -> &str

The signed-in user these requests are made as. Needed by the favourites drain, which reads this user’s queued rows. TRACES: UR-069 | DR-120

pub fn new( http_client: Arc<HttpClient>, server_url: String, user_id: String, access_token: String, ) -> Self

pub fn with_connectivity(self, reporter: ConnectivityReporter) -> Self

Attach a connectivity reporter so server outcomes drive the reachability state observed by the UI. See report_outcome.

async fn report_outcome<T>(&self, result: &Result<T, RepoError>)

Feed a request outcome into the connectivity monitor.

Classification (matches docs/architecture/07-connectivity.md):

• Ok / Authentication / NotFound / Server → the server answered, so it is reachable → report_success (instant recovery).
• Network → connection-level failure → report_network_failure (subject to the time-window debounce before going offline).
• Database → not a server signal → ignored.

fn auth_header(&self) -> String

Build authorization header

pub async fn download_bytes(&self, url: &str) -> Result<Vec<u8>, String>

Download raw bytes from a URL using the shared authenticated HTTP client. Used by thumbnail cache to download images with proper auth and connection reuse.

pub async fn get_jray_actors( &self, item_id: &str, t: f64, ) -> Result<Vec<JRayActor>, RepoError>

Query the JRay plugin for the actors on screen at time t (seconds) in the given item. Returns an empty list when the plugin isn’t installed or has no truth data for the item (HTTP 404), so callers can treat “no JRay” and “nobody on screen” identically. Other failures propagate.

async fn get_json<T: for<'de> Deserialize<'de>>( &self, endpoint: &str, ) -> Result<T, RepoError>

Make authenticated GET request

async fn get_json_inner<T: for<'de> Deserialize<'de>>( &self, endpoint: &str, ) -> Result<T, RepoError>

async fn post_json<T: Serialize>( &self, endpoint: &str, body: &T, ) -> Result<(), RepoError>

Make authenticated POST request

async fn post_json_inner<T: Serialize>( &self, endpoint: &str, body: &T, ) -> Result<(), RepoError>

async fn post_json_response<T: Serialize, R: for<'de> Deserialize<'de>>( &self, endpoint: &str, body: &T, ) -> Result<R, RepoError>

Make authenticated POST request and return response

async fn post_json_response_inner<T: Serialize, R: for<'de> Deserialize<'de>>( &self, endpoint: &str, body: &T, ) -> Result<R, RepoError>

async fn stop_transcode(&self, play_session_id: &str)

Ask the server to tear down a transcode this device started.

Best-effort and deliberately un-retried: it runs on the path that opens a replacement stream, so a slow or failed stop must not delay playback. The worst case if it does fail is the job Jellyfin would have reaped on its own idle timer anyway — the new stream still has its own session id, so it no longer collides with the old one.

TRACES: UR-074 | DR-177

pub async fn get_video_stream_url( &self, item_id: &str, media_source_id: Option<&str>, audio_stream_index: Option<i32>, ) -> Result<String, RepoError>

Get a video stream URL (initial play, resume, transcoded seeking, audio-track switching).

Returns an HLS master playlist (/Videos/{id}/master.m3u8) transcoded to h264/aac. HLS is used rather than a progressive stream.mp4 because the HTML5 <video> element (via HLS.js) starts playing within seconds and can seek within the stream, whereas a progressive MP4 transcode of HEVC source forces the server to transcode the whole file before playback can begin — which manifests as playback never starting.

There is deliberately no start-position parameter. A playlist covers the whole item and asking for segment N is the seek, so a position would be redundant — and actively fatal: Jellyfin builds every segment URI by echoing this playlist’s query string into it, while its segment handler rejects StartTimeTicks > 0 outright (ArgumentException → 400). One resume position here therefore 400s every segment of the stream, which presents as a resumed episode that simply never plays while the same episode from the beginning is fine. Resume by seeking the player once it has loaded. (The progressive /Audio/universal builder below has no segments and keeps its StartTimeTicks.)

The stream is built against the current streaming_quality ceiling: MaxStreamingBitrate/VideoBitrate/AudioBitrate, plus a MaxHeight that suits the budget. Original keeps the historical 20/18 Mbps allowance, which is a transcode ceiling rather than a user-facing limit.

TRACES: UR-004, UR-074 | DR-140, DR-162, DR-177, DR-181 | UT-130, UT-156, UT-173, UT-182

pub async fn build_audio_only_stream_url_for_video( &self, item_id: &str, media_source_id: Option<&str>, start_time_seconds: Option<f64>, audio_stream_index: Option<i32>, ) -> Result<String, RepoError>

Get an audio-only stream URL for a video item, for the background-audio handoff (UR-040).

TRACES: UR-040 | JA-032, DR-140 | UT-059, UT-130

This deliberately targets /Audio/{id}/universal, NOT the video stream: the server extracts/transcodes only the item’s audio track and streams pure audio bytes — no video frames reach the device, so there is no client video decode while backgrounded. Do NOT “optimize” this to reuse the /Videos/.../master.m3u8 URL: that would keep the device decoding video, defeating the entire point of the feature.

AudioStreamIndex carries the user’s currently-selected audio track over from the video player; StartTimeTicks resumes at the handoff position. universal lets the server pick direct-play vs transcode per codec/device.

The stream is a progressive container (mp3 over plain HTTP), NOT HLS: ExoPlayer plays this natively, whereas an HLS/ts transcode on the /universal endpoint (no .m3u8 in the path) fails its progressive loader with ERROR_CODE_PARSING_CONTAINER_UNSUPPORTED. mp3 is universally decodable and supports mid-stream StartTimeTicks.

Trait Implementations

impl MediaRepository for OnlineRepository

fn get_item<'life0, 'life1, 'async_trait>( &'life0 self, item_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<MediaItem, RepoError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fetch one item with every field the detail and player screens need.

The Fields= list is the load-bearing part: Jellyfin omits these unless they are named. MediaStreams is what makes the item’s audio and subtitle tracks knowable at all — there is no separate “tracks” endpoint, so this single call is how the player learns which audio tracks an item offers (to_media_item maps them, and the player’s selector filters them by kind). People is likewise how cast and crew are obtained.

fn get_resume_items<'life0, 'life1, 'async_trait>( &'life0 self, parent_id: Option<&'life1 str>, limit: Option<usize>, ) -> Pin<Box<dyn Future<Output = Result<Vec<MediaItem>, RepoError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Continue Watching: the items this user has started and not finished.

/Users/{uid}/Items/Resume is the server-side answer to both “what goes in the Continue Watching row” and “where was this left off” — each item carries its own UserData.PlaybackPositionTicks, which is why UserData is named in Fields= rather than left to the server’s default field set.

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

“Next Up”: the episode that follows the ones this user has finished, per series — the Shows-scoped counterpart to Continue Watching.

fn get_resume_movies<'life0, 'async_trait>( &'life0 self, limit: Option<usize>, ) -> Pin<Box<dyn Future<Output = Result<Vec<MediaItem>, RepoError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Continue Watching, narrowed to movies — the home screen’s movie row and the movie library’s own hero both want the unfinished films without the episodes mixed in.

fn search<'life0, 'life1, 'async_trait>( &'life0 self, query: &'life1 str, options: Option<SearchOptions>, ) -> Pin<Box<dyn Future<Output = Result<SearchResult, RepoError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Search every library the user can see.

Recursive=true with no ParentId is what makes this cross-library rather than folder-scoped; a caller narrowing the search passes the item types through SearchOptions (already expanded from an opaque SearchScope on this side of the boundary).

Un-favourite an item: the same /Users/{uid}/FavoriteItems/{id} resource as Self::mark_favorite, removed rather than posted. Written out by hand rather than through post_json because it is the one favourite call that needs DELETE.

DELETE /Users/{userId}/PlayedItems/{itemId} — Jellyfin’s “mark unplayed”, which also zeroes the resume position. On a folder (series, season) the server applies it recursively to the children.

A single Person item (actor, director, …) by id.

Jellyfin models people as ordinary items, so this is the plain item endpoint rather than anything under /Persons; the cast entries returned on an item’s People field carry the ids this is called with.
