* perf: binary-search EPG programme lookup
Replaces the linear position() scan with a binary search via partition_point for EPG programmes. Reduces complexity to O(log p).
* perf: cache interned PlaylistItemType label
Avoids repetitive hash-map lookups during sorting and filtering. The five fixed labels are now interned once via OnceLock and returned as a cheap Arc clone.
* perf: avoid per-event String allocation in web-UI XMLTV parser
Uses borrowed Cow types instead of allocating a new String for every element name. Tracks the active text state using a small TextTag enum.
* perf: throttle per-chunk download control poll
Throttles the control_signal lock polling to a 200ms interval on multi-GB downloads to prevent CPU thrashing. Immediate actions (pause/cancel) remain guaranteed via control_notify.
* perf: pre-size filtered channel buffers in apply_filter_to_playlist
Pre-allocates the filtered channel vector based on the source group length. Eliminates step-by-step reallocations on large playlists.
* fix: surface playlist cache load failures instead of silent empty fallback
Replaces silent error swallowing with real error logging (distinguishing missing files from corruption) while preserving the empty fallback behavior.
* perf: remove redundant first drain loop in get_remote_content_as_file
Removes a dead, redundant loop. The stream body is now consumed only once, allowing the idle timeout to protect the transfer correctly.
* perf: back off instead of busy-spinning on empty client-stream chunks
Introduces a short Sleep backoff (Poll::Pending) when a provider sends continuous empty keep-alive chunks. Prevents the CPU from spinning hot.
* perf: make library orphan cleanup linear instead of O(n^2)
Reduces the complexity of cleaning up orphaned entries from O(n^2) to linear O(n). Loads the metadata library only once and pre-computes partitions.
* perf: indexed batched merge for series expansion instead of O(n^2) scans
Replaces expensive O(n^2) scans during series expansion with index-based batch processing. Builds temporary lookup indexes and merges groups linearly.
* perf: pre-size group flatten buffers to reduce reallocation churn
Pre-allocates target merge vectors and category indexes to eliminate repeated memory reallocations when flattening large target playlists.
* perf: stream custom provider playlist endpoint instead of materializing it
Switches from full in-memory materialization to lazy conversion and streaming of JSON/binary responses. Massively reduces the memory footprint.
* refactor: centralize InputType batch/family checks behind enum helpers
Moves scattered matches! checks for M3u/Xtream types into centralized enum helpers (is_batch(), etc.) to prevent logic drift.
* refactor: centralize XMLTV tag/attribute literals into named constants
Replaces hardcoded inline strings in the XMLTV parser with named constants (EPG_TAG_TITLE, etc.) as a single source of truth.
* refactor: derive GeoIpUpdateError Display/Error via thiserror
Replaces manual Display and Error implementations with the thiserror macro, allowing new error variants to self-document their formatting.
* refactor: attach per-cluster facts to XtreamCluster instead of scattered matches
Centralizes redundant API actions and collection name mappings directly onto the XtreamCluster struct instead of using scattered match blocks.
* refactor: centralize PlaylistItemType video/series classification
Introduces is_video() / is_series() on the enum to unify duplicate matches! checks across filters, probes, and tracking modules.
* feat: add per-stage summary logs to VOD/series resolve queueing
Adds a concise debug summary per processing stage (total counters and elapsed time) to make hot-path diagnostics easier without raising the log level.
* refactor: generate ItemField get/set from a single direct-field list
Uses a callback macro to synchronously generate both getter and setter blocks for directly-bound fields (Name, Url, etc.) from a single master list.
* refactor: derive input-type routing from a single capability descriptor
Bundles InputType behaviors (backends, connection rules) into a single capabilities() descriptor to prevent bugs when adding new variants.
* refactor: derive output-format routing from a single capability descriptor
Centralizes output format features (filter, EPG, and cache support) into a single TargetCapabilities descriptor instead of spreading logic across no-op match arms.
* feat(ui): toast progress bar, pause-on-hover, and copy-details for errors
Add a countdown progress bar to auto-dismiss toasts, pause both the timer and bar on hover (resuming with remaining time), and a 'copy details' action on error toasts. Respects prefers-reduced-motion.
* feat(ui): confirm destructive download/recording cancel and remove
Route the download/recording cancel and remove actions through the shared ConfirmDialog (which focuses the safe Cancel button by default), matching the existing confirmation flow for user/target/RBAC deletes.
* feat(ui): runtime-discovered languages with manifest and RTL support
Load available UI languages at runtime from assets/i18n/index.json, add a toolbar language picker (shown when >1 language), persist the choice, and set document dir/lang for RTL languages such as Arabic.
* feat(ui): recoverable error boundary with per-view retry fallback
Add an ErrorBoundary component (context handle + use_error_boundary hook) that shows a recoverable fallback with a retry button instead of blanking a section. Wrap each main view and the API-user playlist individually so a failure in one view stays contained and the rest of the UI keeps working.
* fix(api): use async canonicalize in local file stream handler
Replace the blocking std path.canonicalize() in local_stream_response with tokio::fs::canonicalize().await so the async runtime is not blocked while resolving the local media file path.
* Add Escape-to-close keyboard support for popup menus
Popup menus now close on Escape in addition to outside mouse-down, improving keyboard accessibility.
* Use descriptive alt text for logo and channel logo images
Login and sidebar logo images now use the configured app title, and playlist channel logos use the channel title, improving screen-reader accessibility.
* Add explicit type=button to shared button primitives
IconButton and TextButton now render with type=button to prevent accidental form submission when used inside forms.
* Persist sidebar collapsed state and table page size
The sidebar collapsed/expanded state and the stream-history table page size are now saved to localStorage and restored on reload, matching the already-persisted theme preference.
* Debounce filter editor input parsing
The filter editor textarea no longer re-parses, previews, and emits the filter on every keystroke. The textarea stays responsive via an immediate value while parsing and change notifications are debounced (300ms).
* Show localized message in table empty state
Data/paged tables now render the No content label in their empty state instead of an icon with no text. Sticky headers were already present.
* feat(frontend): improve screen-reader support for sidebar and toasts
* fix(frontend): handle missing window gracefully in sidebar

New Features
Background probing for Live streams with configurable interval; new input options to trigger probing and toggle background resolution.
Configuration Changes
metadata_update reorganized into grouped sections: log, resolve, probe, ffprobe, tmdb.
FFprobe controls moved under ffprobe.* and now require explicit time/size units; new live ffprobe settings.
Added metadata_update.tmdb.cooldown (default 7d) and grouped TMDB settings.
Bug Fixes
TMDB no-match cooldown to prevent endless requeues.
Documentation
README and UI help updated to reflect grouped metadata_update fields and explanations.
Fixed m3u playlist with provider_config persistence as text file
Added probe_delay input option (default 2s); stream probing renamed “Stream Probing” and now covers live, VOD and series as a low‑priority background task.
**Description:**
This PR introduces a major overhaul of how streams are analyzed and connections are managed. It integrates `ffprobe` for deep stream analysis, adds a background task queue for metadata resolution to prevent UI blocking, introduces a connection priority system, and adds support for Live TV probing.
### 🚀 Key Features
* **FFprobe Integration & Live TV Probing**:
* Automatically probes streams (VOD/Series **and now Live TV**) to determine resolution, codecs (HEVC/AV1), dynamic range (HDR/DV), bit depth, and audio channels.
* **Safe Probing**: Probing strictly respects the provider's `max_connections` limit.
* Docker images now include static `ffmpeg/ffprobe` binaries.
* **Smart Connection Management (Priority System)**:
* Introduced a priority system for connections to manage provider limits intelligently.
* **Preemption**: Users with higher priority can preempt (kick) lower priority connections when provider slots are full.
* **Background Queue**: Metadata resolution and stream analysis run as background tasks (Priority 0). They only run when connection slots are idle and yield immediately if a real user needs to stream.
* **Enhanced Metadata Resolution**:
* **Fallback Logic**: If a provider is missing the TMDB ID or Release Date, the system resolves them via the TMDB API.
* **Smart Title Cleaning**: Implemented a centralized cleaner to strip common IPTV prefixes before attempting metadata matches or generating filenames, significantly improving match rates.
* **Improved Output**:
* **Quality Tags**: Filenames in STRM files now include detailed tags (e.g., `Movie - [4K HEVC HDR].strm`).
* **Flat Grouping**: `flat: true` now correctly groups multi-version movies into single folders based on TMDB ID.
* **Global Series Date**: Ensures consistent series folder naming even if episodes have different years.
An optimization has been introduced to reduce memory consumption during playlist updates.
Overview
Previously, provider playlists were fully loaded into memory during the update process. For large playlists (e.g. hundreds of thousands of entries or multiple providers), this could result in significant RAM usage.
With the new implementation, it is now possible to optionally read provider playlists directly from disk instead of keeping them entirely in memory.
How It Works
- users can configure whether:
- Provider playlists are loaded into memory (previous behavior), or
- Provider playlists are streamed to/from disk to minimize RAM usage.
Processing remains sequential and batch-based, ensuring identical functional behavior.
This approach significantly lowers peak memory usage, especially on systems with limited resources.
Benefits
- Reduced peak RAM consumption during playlist updates
- Better scalability for large playlists and multiple providers
- Full backward compatibility
Trade-offs / Drawbacks
- Increased processing time due to reduced in-memory caching
- Higher disk I/O usage, especially for large or fragmented playlists
- Performance depends more strongly on disk speed (Nvme SSD, HDD)
- Slightly increased CPU overhead due to repeated parsing and deserialization
- Not optimal for environments where fast updates are more important than memory usage
Recommendation
- Use in-memory mode for systems with sufficient RAM and a focus on update speed
- Use disk-based mode for large playlists, multiple providers, or memory-constrained environments
