Selectable alternate audio tracks on PeerTube videos, so multilingual creators stop uploading one video per language
Creators and multilingual organizations on PeerTube -- the federated, self-hostable YouTube alternative -- want selectable alternate audio tracks (e.g. dubbed languages) on a single video instead of uploading one copy per language. PeerTube supports multiple subtitle tracks but only one audio track, so today people duplicate uploads, wasting storage and splitting their view counts, comments, and audience. The long-open request is still drawing fresh interest from multilingual companies, filmmakers, and screen-reader users.
Frame it as 'one upload, many languages' for dubbed and multilingual channels, not a generic player tweak; the duplicate-upload pain (storage plus split audience) is the real wedge, and since HLS already supports multiple audio renditions the hard part is the transcoding pipeline and a clean track-picker in the player, not the spec.

Multilingual and dubbed-content channels on the federated, self-hostable YouTube alternative have no way to attach selectable audio tracks; HLS already carries multiple audio renditions, so the gap is PeerTube's transcoding pipeline and player UI, not a fundamental limitation.
