# `Laev.Tracks`
[🔗](https://github.com/alexdont/laev/blob/main/lib/laev/tracks.ex#L1)

Audio / subtitle languages of a resolved stream.

Release names only hint at audio ("Rus-Eng", "MULTi") and say nothing
about subtitles, so the picker used to guess. Real-Debrid's
`/streaming/mediaInfos` reads the actual container server-side and lists
every track with an ISO 639-2 code; this module folds that answer into
`%{audio: ["ru", "en"], subs: ["ru"]}` — the two-letter codes the rest of
laev already speaks (`Laev.Config.lang/0`, Torrentio flags) — and renders it
for the source row.

# `from_media_info`

`%{audio: [..], subs: [..]}` from a mediaInfos body: two-letter codes in
container order, deduped, undetermined tracks dropped. Never fails —
a body without `details` yields empty lists.

# `label`

Row suffix like `🔊ru·en 💬ru`; sections with nothing known are left out,
so a stream with no track info renders as "".

# `rankable`

Codes safe to rank on: `Laev.Config.lang/0` / `Laev.Config.subs_lang/0` are
two-letter, so a 639-2 code we couldn't fold ("pob") would never match
and must not sink a release — it stays visible in the row, that's all.
