#Picking a source

The source drawer lists every stream the addons returned for this title, with quality, codec, size and release details parsed out of each addon's stream label. Addons publish those as free text in whatever shape they like, so the parser is a best effort — it will not invent a field it could not find.

Auto-pick honours the preferred resolution set in Settings → Playback. auto means "take the addons' own order", which is the order you arranged your addons in.

Moving on to the next episode stays on the same release: the stream from the same addon that the addon marks as the same release (its bingeGroup), when the next episode has one. Otherwise the usual auto-pick applies.

Reuse last link (Settings → Playback) re-opens a title with the stream URL it used last time instead of resolving it again. Handy for debrid addons where re-resolution is slow. Remembered links expire after linkCacheDays (3 by default, matching most debrid providers).

#Playback

.m3u8 plays through hls.js; anything else goes to the <video> element's own src. Audio-track switching works on either.

Before a stream reaches <video>, its codec is probed. Playback that decodes no frames (an unsupported HEVC or AV1 stream) raises a dismissible banner naming the problem, instead of leaving you with a black screen and no explanation.

A direct file the browser can't play as is gets fixed in the browser: the player reads the file itself, passes the video through untouched, and feeds the result to <video> through Media Source Extensions. The stream never goes through the server. Two things trigger it:

• Audio the browser doesn't decode (Dolby Digital, Dolby Digital Plus, DTS). It is decoded with WebAssembly and re-encoded to stereo, and the stream loader says so while it switches. The player reads the file's audio tracks as playback starts and switches straight away; the silence check a few seconds in is only a backstop. Surround is not preserved.
• A container the browser refuses (Matroska where <video> doesn't play it). Audio the browser decodes is copied as is.

It needs a host that allows cross-origin range reads and a browser with MediaSource. When either is missing, or the audio is a format it doesn't decode (TrueHD), you get the banner or the error screen as before.

#Audio track

A file with more than one audio track starts on your preferred audio language (Settings → Playback) when it has one, and the audio button in the control bar switches between them. Browsers that can't switch tracks in a plain file get the in-browser fix above for that, with the audio copied untouched.

#Reloading

The player's address carries what a reload needs: the stream that is playing, the position, the volume boost and the audio track. The stream is a short key, not its URL: the link itself stays in this browser's storage, so a debrid URL never lands in the address bar, the history, or a link you paste to someone. Opened in another browser, the key means nothing and a stream is resolved as usual.

#Subtitles

Subtitles come from your addons and from the stream itself. Addon files (SRT, ASS / SSA, WebVTT) are converted to WebVTT in the browser, so a subtitle file never touches the server. A file that isn't valid UTF-8 is read as Windows-1252, which is what most older French and other Western European SRTs are in. ASS styling is dropped: you get the text, with its line breaks and timing.

The stream's own tracks are listed alongside, marked Embedded: HLS subtitle renditions, the text tracks the browser exposes for a file it plays itself, and a Matroska file's text subtitles (SRT, ASS / SSA, WebVTT) when it goes through the in-browser fix. Those last ones are read from the bytes the fix downloads anyway, so they fill in as playback moves forward. Image subtitles (PGS, VobSub) are not shown.

Size, colour, a semi-opaque background plate and an outline are configurable, and a preferred language is auto-selected when a stream carries a matching track. All of it lives in Settings → Playback.

The timing nudge (in the subtitles menu, or G / H) applies to whichever track is showing, and stays when you switch tracks or move to another source of the same video.

#Skip intro and outro

Intro and credits timestamps come from two community databases, neither of which needs any server configuration:

• TheIntroDB, asked first. The public keyless tier works out of the box. Adding your own API key in Settings → Integrations folds your pending submissions into the lookup and raises your rate limits. The key is stored per profile on your Nuvio account, never as a server environment variable.
• AniSkip, when TheIntroDB has nothing at all for the title. It is where anime skip times live, and anime is where TheIntroDB is thinnest. AniSkip is keyed by MyAnimeList id, so the title's IMDb, TMDB, Kitsu or AniList id is first mapped through ARM. For an IMDb or TMDB series, ARM lists one MyAnimeList entry per season, and the player asks for the one matching the season you are watching. The mapping is also the anime detection: ARM knows nothing about a title that is not anime, so that lookup ends there.

A missing id mapping, a 404 (no community data yet), a rate limit or a timeout all resolve to "no segments", and the player simply does not show the skip affordances.

Skip intro and credits (Settings → Playback, off by default) skips the intro on its own, once per source, and goes from the credits straight to the next episode instead of the up-next countdown. The last episode still ends on the end panel.

#Volume boost

The speaker button beside the volume slider boosts volume to 150%, 200% or 300%, with a badge beside the volume slider while it's on. Audio goes through Web Audio: a gain, then a limiter, so loud peaks saturate instead of clipping. Nothing is routed until you first pick a boost, so normal playback never touches Web Audio.

HLS streams, downloads and same-origin files can always be boosted. A direct file from another host can only be boosted when that host sends CORS headers, because Web Audio plays a cross-origin file loaded without CORS as silence. A one-byte probe checks first; if it passes, the video reloads with CORS at the same position, and if not you get a notice and playback carries on untouched. The boost stays on for the title you're watching, across sources and reloads, and resets when you move to another one.

#Chapters

The scrub bar marks chapter boundaries, and hovering it names the chapter under the cursor.

A file's own chapters come first: Matroska / WebM Chapters and MP4 Nero chpl, else an MP4 QuickTime chapter track. The browser reads them from the container's metadata with a few small Range requests. The server never touches a stream's bytes, and the reads stop short of the media: a Matroska walk ends at the first Cluster, and an MP4 walk skips mdat by its size, going in only for a chapter track's titles. A host that doesn't answer with CORS headers, or that ignores Range, just yields no chapters. A 200 is aborted unread, so the file is never downloaded twice. HLS streams aren't read.

When the file has no chapters, the intro and credits timestamps above stand in as "Intro" and "Credits".

#Auto-play next

On by default. An end-of-episode panel counts down to the next episode and lets you stop it. Turn it off in Settings → Playback.

Only an episode that has aired counts as next. When the next one is listed but not out yet, there is nothing to play, so the show ends instead and the end panel says when that episode airs. Continue Watching follows the same rule: a finished episode rolls forward only to one that has aired, and the card comes back on its own once the next one does. The air date comes from the addon's listing, or from TVmaze when the addon lists nothing past the last episode.

#System media controls

The lock screen, the media keys and a headset's buttons see what is playing, with its poster, and can play, pause, seek and skip to the next episode.

#Casting

No third-party SDK is involved. The player uses the standard Remote Playback API, which reaches Chromecast on Chrome and Edge, and falls back to WebKit's AirPlay hooks in Safari.

#Playing somewhere else

There is no web API for "open in the OS default player", and a scheme cannot simply be glued in front of a URL. Each platform gets its own correctly encoded form:

#Keyboard shortcuts

Every control also carries its shortcut in its hover tooltip, so the icons do not have to be learned from this table. Outside the player, / opens search.

Shortcuts are bound on the window, but a key aimed at a focused control is left alone: Space on a focused button inside the sources, subtitles or episodes panel activates that button, as a keyboard user expects, rather than toggling playback. Esc is the exception — it has to work from inside an open panel, so it always closes it.
