OGPlayer — web SDK

OGPlayer for the browser — built on web standards.

Release notes: https://ogplayer.tv/docs/reference/changelog/

OGPlayer is a product of Inverse DOO.

Under the hood

• Playback: the browser's <video> element plays the media. HLS streams are fed to it through hls.js using Media Source Extensions; Safari plays HLS natively so hls.js steps aside there. MPEG-DASH (an .mpd URL, or mimeType: "application/dash+xml") goes through dash.js, also on MSE — same API, events, menus and DRM config as HLS. Progressive MP4 plays directly.
• UI: a custom element <og-player> that works identically in plain HTML, React, Vue and Angular, with all styles isolated in a shadow DOM so host-page CSS can't break the player (and vice versa).
• Types: written in TypeScript — full type declarations ship with the package.
• License: signed OGP2.… offline keys, verified with the browser's built-in WebCrypto. apps patterns bind to the page hostname.

Quick start

<script type="module">
  import { OGPlayer } from "ogplayer";

  const player = new OGPlayer({ licenseKey: "OGP2...." });
  document.querySelector("og-player").player = player;

  player.addListener({
    onStateChanged: (s) => console.log(s),
    onProgress: (positionMs, bufferedMs, durationMs) => {},
  });
  player.load({
    url: "https://example.com/stream.m3u8",
    title: "My movie",
    contentRatings: [{ age: "SIXTEEN" }, { descriptor: "FEAR" }],
    sideloadedSubtitles: [{ url: "/subs/en.vtt", language: "en", label: "English", isDefault: true }],
  });
</script>

<og-player style="width:100%;aspect-ratio:16/9"></og-player>
Copy

Overlays (watermarks, logos) use the nine named OverlaySlots — including the clearance choreography around the controls and rating icons:

<og-player>
  <img slot="top-end" src="/logo.png" width="90">
</og-player>
Copy

Custom action icons (max 8, inline in the top-end control row, hide with the controls):

el.config = {
  customActions: [
    { svg: shareIconSvg, accessibilityLabel: "Share", onClick: () => share() },
  ],
};
Copy

Keyboard shortcuts

While the player has focus (it takes focus on any click) the keys viewers expect just work: Space/K play-pause, ←/→ and J/L seek by the seek increment, ↑/↓ volume, M mute, F fullscreen, C subtitles, 0–9 jump to 0–90 % on VOD, Home/End start/end (live edge on live), Esc leaves fullscreen. Seek keys obey the live rules and stay inert during ads; modifier chords and unmapped keys reach the page untouched. Turn it off with el.config = { keyboardShortcuts: false } or change single keys with el.config = { keymap: { m: null, p: "toggleMute" } }.

Localisation

Every word of the chrome — labels, menu rows, ARIA labels, ad and error copy — comes from el.config = { strings: { subtitles: "Ondertiteling", retry: "Opnieuw proberen" } }, a partial map over the English defaults with the same keys as every other OGPlayer platform (the vertical feed's config takes strings too). <og-player lang="nl"> or config.locale names language-coded tracks via Intl.DisplayNames; nothing is taken from the browser's language.

Picture-in-picture

API-only — no PiP button in the chrome; the host decides: await player.enterPip() from a user gesture (resolves false where the browser offers no PiP or during an ad), exitPip(), isInPip, and new OGPlayer({ autoEnterPip: true }) to let the browser auto-enter where it offers that. Transitions: onPipChanged, og-pipchanged, PictureInPictureChanged.

How it ships

1. npm (the web's Maven Central): npm install ogplayer — ESM module with TypeScript types, hls.js pulled in as the npm dependency. dash.js ships inside the package — nothing extra to install: the ESM bundles import it as a separate chunk (dist/ogplayer.dash-*.js) on the first DASH item, so HLS-only pages never download it, and dist/ogplayer.dash.global.js is the same engine for <script> pages. A host that bundles its own dash.js can pass it as new OGPlayer({ dashjs }). Publishing is one scripts/release.sh <version> run (build, tests, tarball guard, npm publish).
2. CDN script tag for no-build websites: dist/ogplayer.global.js is a single self-contained file (hls.js included) exposing window.OGPlayerSDK. Served straight from the npm package via unpkg (or any CDN mirror of npm). Pages that play DASH add dist/ogplayer.dash.global.js (the DASH engine) with a second <script> tag — the TV global bundle takes the same file.
3. Smart-TV bundle — ogplayer/tv (dist/ogplayer.tv.js ESM, dist/ogplayer.tv.global.js global): the same API, compiled for the Chromium 68/69 engines 2020+ Samsung Tizen and LG webOS TVs are frozen at, without the vertical feed. TV behaviour is opt-in on either bundle: <og-player input="remote"> (D-pad/OK/Back/media-key chrome), platformProfile: "tv" (bounded buffers for set-top SoCs) and licenseAppId (packaged apps run from file://). npm run build gates the source against that ceiling (tsconfig.tv.json, scripts/tv-compat-check.mjs).

<script src="https://unpkg.com/ogplayer@1.6.0/dist/ogplayer.global.js"></script>
<!-- smart TVs: dist/ogplayer.tv.global.js instead — packaged apps copy it in -->
<!-- DASH items: add dist/ogplayer.dash.global.js here (same folder) -->
<script>
  const player = new OGPlayerSDK.OGPlayer();
  document.querySelector("og-player").player = player;
  player.load({ url: "…" });
</script>
Copy

Browser support

Evergreen Chrome / Edge / Firefox / Safari 16+ (desktop & mobile). Every API used (MSE, custom elements, shadow DOM, WebCrypto, Fullscreen) has been baseline for years; no polyfills.

The TV bundle (ogplayer/tv) deliberately reaches further back: its floor is the Chromium 68/69 of 2020 Samsung Tizen 5.5 and LG webOS 5 sets — syntax lowered by esbuild, built-ins held to ES2018, DOM and CSS gated by the compat check — so it runs on any TV browser of that generation or newer. No polyfills there either.
