4grayandClaude Fable 5 f58460380f fix(stalker): fall back to short EPG when bulk EPG misses the current programme (#1386)
* fix(stalker): fall back to short EPG when bulk EPG misses the current programme

Some portals' bulk get_epg_info returns only future programmes — the one
airing now is absent. The ITV channel-list previews read exclusively from
that bulk map, so every row showed 'No program information available', and
the EPG panel preferred any non-empty bulk list over the short-EPG fallback,
so it showed upcoming shows with no 'on now' entry. Recently Viewed uses
get_short_epg per channel, which is why the same channel worked there.

Panel: merge the short-EPG fallback into the bulk list instead of either/or,
and trigger the fallback whenever the bulk list has no currently airing
programme (not only when it is empty).

Rows: new throttled StalkerEpgPreviewQueue (mirroring Xtream's
EpgQueueService — bounded concurrency, inter-request spacing, 5-minute cache
including empty results, reset on playlist switch) fetches get_short_epg for
rendered channels the settled bulk guide cannot answer.

Docs: stalker-epg.md fallback contract updated accordingly.

* fix(stalker): bound the preview-queue burst and keep mapped channels portal-free

Review follow-up (Codex P1/P2 on #1386):

P1 — request volume: each queue sync is now capped at 30 channels (top of
the list first, where a freshly opened category is scrolled to), and the
sidebar scroll handler re-syncs (throttled, 300 ms) to fill the next gaps.
Request count now tracks how far the user scrolls instead of how many rows
are rendered; caching (including empty results) and 200 ms pacing remain.

P2 — manual mappings: a channel whose bulk record comes from a manual XMLTV
mapping never falls back to the portal short EPG. The panel path resolves
the channel's mapping before falling back and bails when an override owns
the channel; the row path excludes overridden channels from both the queue
and its cache. New store query hasItvEpgMappingOverride() exposes override
ownership; merging portal data into a mapped schedule could otherwise
surface the portal's programme — the exact thing the mapping replaces.

Docs updated (stalker-epg.md); regression tests for the cap, the mapped-
channel suppression, and the override query.

* fix(stalker): scope the panel EPG fallback by channel and revalidate queued previews

Review follow-up (Codex round 2 on #1386):

The panel's short-EPG fallback is now stored with the channel id it was
fetched for, and activeEpgPrograms merges it only while that channel is
still selected. A channel switch moves the selection synchronously but the
old fallback is replaced only after the new channel's EPG load runs, so the
unscoped merge mixed the previous channel's programmes into the new panel
during slow playback resolution — and left them there when resolution
failed.

The row-preview queue's completion callback now revalidates ownership: a
row claimed while the fetch was in flight — by a manual mapping override or
by bulk data — is never overwritten by the late portal response.

Both races covered by a new focused spec (verified to fail on the pre-fix
component); stalker-epg.md updated.

* fix(stalker): supersede the preview backlog on view exit and own empty mappings

Review follow-up (Codex round 3 on #1386):

The preview queue is now superseded when the rendered channel list empties
(a legacy-paged category switch clears it before the new channels arrive)
and when the view leaves ITV for radio — an abandoned view's backlog no
longer keeps issuing get_short_epg requests for rows that are gone.

Mapping ownership is now tracked separately from the mapped guide's
programs: a saved mapping whose XMLTV channel currently has no entries
still owns its channel, so hasItvEpgMappingOverride() keeps the portal
short-EPG fallback out — consistent with a mapping's purpose of replacing
portal data.

Both covered by regression tests (verified to fail pre-fix; the ITV-exit
test re-arms the backlog after init because the playlist effect's first run
resets the queue); stalker-epg.md updated.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* docs(stalker): reconcile every EPG contract reference with the row fallback

Review follow-up (Codex round 4 on #1386): the overview, get_short_epg API
notes, and data-mapping sections of stalker-epg.md still stated that rows
never issue per-row requests, and the stalker-portal skill instructed that
only the active channel may fall back — contradicting the contract this PR
establishes. All references now describe the bulk-first row previews with
the throttled short-EPG fallback queue. skills:validate passes (the skill
stays within its 500-word budget).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(stalker): publish empty-mapping ownership reactively

Review follow-up (Codex round 5 on #1386): when the row-preview fetch
finishes before the mapping lookup, a portal programme is already rendered.
An empty mapped guide then recorded ownership only in a plain Set — no
state was patched, the preview effect never reran, and the stale portal row
survived. applyMappedItvEpg now re-patches bulkItvEpgByChannel (identical
content, new reference — deliberately) whenever it establishes new
ownership, even without programs, so the rerun sync removes the fallback
row. Store regression test extended (fails pre-fix); stalker-epg.md updated.

IPTVnator - IPTV Player Application

IPTVnator icon

Release CI status Releases Codecov Telegram Bluesky

🌐 Website | Telegram channel for discussions | Buy me a coffee | GitHub Sponsors

IPTVnator is a video player application that provides support for IPTV playlist playback (m3u, m3u8). The application allows users to import playlists using remote URLs or by uploading files from the local file system. Additionally, it supports EPG information in XMLTV format which can be provided via URL.

The application is a cross-platform, open-source project built with Electron and Angular.

⚠️ Note: IPTVnator does not provide any playlists or other digital content. The channels and pictures in the screenshots are for demonstration purposes only.

Important

Official sources only. IPTVnator is a free, open-source player — it never sells IPTV subscriptions, channels, or playlists. Websites offering "IPTVnator subscriptions/channels/premium/activated" builds are not affiliated with this project. Get the app only from the official website or GitHub Releases. See Beware of unofficial IPTVnator websites and IPTV services for details.

Note: First version of the application which was developed as a PWA is available in an extra git branch.

Self-hosted PWA

The Docker setup builds the Angular PWA and the monorepo web backend into one image. The backend handles remote M3U parsing plus Xtream and Stalker proxy requests under /api, so a separate 4gray/iptvnator-backend container is not required for the default self-hosted flow.

docker compose -f docker/docker-compose.yml up --build -d

The application is available at http://localhost:4333. See docker/docker-compose.yml for the ready-to-run compose file and docker/README.md for environment variables, reverse proxy notes, PWA limitations, and build details.

The self-hosted image runs the browser PWA rather than the Electron desktop app: EPG/XMLTV panels, Embedded MPV, managed MPV/VLC launching, the download manager, and Electron remote-control features are not available there. If browser playback fails, copy the stream URL and open it manually in an external player such as MPV, VLC, or IINA.

Download

Download the latest version of the application for macOS, Windows, and Linux from the release page.

Alternatively, you can install the application using one of the following package managers:

Homebrew

$ brew install iptvnator

Snap

$ sudo snap install iptvnator

Arch

Also available as an Arch PKG, iptvnator-bin, in the AUR (using your favourite AUR-helper, .e.g. yay)

$ yay -S iptvnator-bin

Gentoo

You can install IPTVnator from the gentoo-zh overlay

sudo eselect repository enable gentoo-zh
sudo emerge --sync gentoo-zh
sudo emerge iptvnator-bin

Linux Embedded MPV Support

Embedded MPV on Linux is experimental and currently supports x64 desktop sessions where IPTVnator runs under X11 or Xwayland. Native Wayland embedding is not supported yet. Linux package launchers request X11 with --ozone-platform=x11, so Wayland desktops still need Xwayland available.

The Linux backend starts a system mpv executable with --wid, so mpv must be installed and available on PATH. CI validates the Linux native addon and standard packages on Ubuntu 22.04, with Flatpak packaging built on Ubuntu 24.04. Expected user targets are Ubuntu/Debian .deb, Arch/Manjaro pacman, RPM distributions, and AppImage on x64 systems with X11/Xwayland plus mpv installed. Flatpak and Snap builds remain available, but embedded MPV is not announced as supported there yet because those sandboxed formats do not expose the host mpv executable to the embedded backend by default.

Get it from the Snap Store

Troubleshooting

macOS: "App is damaged and can't be opened"

Older unsigned macOS builds may require removing the quarantine flag from the downloaded application:

xattr -c /Applications/IPTVnator.app

Alternatively, if the app is located in a different directory:

xattr -c ~/Downloads/IPTVnator.app

Linux: chrome-sandbox Issues

If you encounter the following error when launching IPTVnator:

The SUID sandbox helper binary was found, but is not configured correctly.
Rather than run without sandboxing I'm aborting now.
You need to make sure that chrome-sandbox is owned by root and has mode 4755.

Solution 1: Fix chrome-sandbox permissions (Recommended for .deb/.rpm installations)

Navigate to the IPTVnator installation directory and run:

sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox

Solution 2: Launch with --no-sandbox flag

Edit the desktop launcher file to add the --no-sandbox flag:

  1. Find your desktop file location:

    • Ubuntu/Debian: ~/.local/share/applications/iptvnator.desktop
    • System-wide: /usr/share/applications/iptvnator.desktop
  2. Edit the file and modify the Exec line:

    Exec=iptvnator --no-sandbox %U
    
  3. Save the file and relaunch the application from your application menu.

Alternatively, you can launch IPTVnator from the terminal with the flag:

iptvnator --no-sandbox

GNU/Linux: Wayland startup failure

If IPTVnator exits on GNU/Linux with errors about failing to connect to Wayland or initialize the Ozone platform, force X11/XWayland instead:

iptvnator --ozone-platform=x11

This workaround is mainly for older or problematic Linux graphics stacks. The Snap package already includes this X11 override by default. For AppImage, direct binaries, and other Linux package formats, pass the flag manually when needed.

How to Build and Develop

Requirements:

  • Node.js with pnpm (via Corepack)
  1. Clone this repository and install project dependencies:

    $ corepack enable
    $ pnpm install
    
  2. Start the application:

    $ pnpm run serve:backend
    

This will open the Electron app in a separate window, while the Angular dev server will run at http://localhost:4200.

The equivalent Nx command is:

$ nx serve electron-backend

To start Electron with an empty, isolated data directory instead of your normal ~/.iptvnator folder, set IPTVNATOR_E2E_DATA_DIR for that run:

$ rm -rf .tmp/iptvnator-empty && mkdir -p .tmp/iptvnator-empty
$ IPTVNATOR_E2E_DATA_DIR="$PWD/.tmp/iptvnator-empty" pnpm run serve:backend

This redirects the SQLite database, Electron user data, and local config under the given directory. Delete that directory whenever you want a fresh empty state.

If you need startup diagnostics for a white screen or a frozen route, you can also turn on opt-in Electron tracing. These logs are written to the Electron terminal output so they still help when the renderer DevTools never open:

$ IPTVNATOR_TRACE_STARTUP=1 pnpm run serve:backend

Nx equivalent:

$ IPTVNATOR_TRACE_STARTUP=1 nx serve electron-backend

Useful narrower flags:

  • IPTVNATOR_TRACE_IPC=1 logs renderer window.electron.* calls reaching the Electron bridge
  • IPTVNATOR_TRACE_DB=1 logs DB worker requests and request-scoped DB events
  • IPTVNATOR_TRACE_SQL=1 logs SQLite statements in both the main connection and DB worker connection
  • IPTVNATOR_TRACE_WINDOW=1 logs BrowserWindow load, navigation, and unresponsive events
  • IPTVNATOR_TRACE_RENDERER_CONSOLE=1 mirrors renderer console messages into the Electron terminal output

Security-sensitive network compatibility flags are opt-in:

  • IPTVNATOR_ALLOW_PRIVATE_NETWORK_URLS=1 permits strict EPG fetches from playlist metadata (x-tvg-url, url-tvg, or tvg-url) to resolve to localhost, LAN, or other private addresses. Directly configured Xtream/Stalker portals and private playlist servers remain supported without this flag. Prefer the in-app source-scoped “Allow source” action for a trusted EPG URL.
  • IPTVNATOR_ALLOW_INSECURE_TLS=1 disables certificate validation for remote playlist imports and refreshes for the whole Electron process. Prefer the in-app host-scoped trust action for a trusted provider with a self-signed or otherwise invalid certificate.

If the local Nx daemon gets into a bad state before rerunning Electron, reset it:

$ pnpm nx reset

To run only the Angular app without Electron, use:

$ pnpm run serve:frontend
