Videos with multi-language audio carry an `audioTrack` object on each audio entry of `streamingData.adaptiveFormats`, holding the language id (e.g. "en-US.4"), a human-readable `displayName`, and whether the track is the original audio. Invidious already parses and uses all three: the DASH manifest route reads `audioTrack["id"]`, `audioTrack["audioIsDefault"]` and `audioTrack["displayName"]` to label and order its audio AdaptationSets. But `/api/v1/videos` drops it, so an API consumer has no way to tell one audio track from another, and is left scraping it back out of the stream URL query string (`xtags=acont%3Ddubbed%3Alang%3Dfr`) — undocumented, and silent when it changes. Emit the same three fields the manifest route already relies on, each only when present, in the same passthrough style as the neighbouring `colorInfo` and `captionTrack` fields. Additive and optional throughout: a single-audio video carries no `audioTrack` at all and so gains no field, which is correct — there is no second track to distinguish. AI disclosure, per AI_POLICY.md: this patch was written with AI assistance. Exact model: Claude Opus 5, model ID `claude-opus-5[1m]`. Tool used to interact with it: Claude Code, Anthropic's agentic CLI. The change was verified against a live patched instance (see the PR for the measurements) and is running in production on the submitter's instance. Submitted by and the responsibility of @mdbraber.
