SnapOtterandGitHub 00b651c9f8 feat(i18n): 21-language pipeline, landing/docs/API wiring, landing+API translations

Shared Claude Code translation pipeline (scripts/i18n, no API key) plus Astro/VitePress/Scalar i18n wiring. Landing and API reference translated into all 20 languages; docs i18n wiring + English source anchors. The translated docs markdown (apps/docs/<locale>/**, 3,620 files) follows in a companion PR because it exceeds GitHub's per-PR CI file limit.

Generate subtitle files from video audio tracks using AI.

Auto Subtitles

Generate subtitle files from a video's audio track using AI-powered speech recognition (faster-whisper). Supports auto-detection and 10 explicit languages.

API Endpoint

POST /api/v1/tools/video/auto-subtitles

Accepts multipart form data with a video file and a JSON settings field. This is an async endpoint - it returns 202 Accepted immediately and progress is streamed via SSE at GET /api/v1/jobs/{jobId}/progress.

Parameters

Parameter	Type	Required	Default	Description
language	string	No	`"auto"`	Speech language: `auto`, `en`, `de`, `fr`, `es`, `zh`, `ja`, `ko`, `id`, `th`, `vi`
format	string	No	`"srt"`	Output subtitle format: `srt`, `vtt`

Example Request

curl -X POST http://localhost:1349/api/v1/tools/video/auto-subtitles \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@clip.mp4" \
  -F 'settings={"language": "en", "format": "srt"}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "async": true
}

Notes

This is an AI tool that requires the transcription feature bundle to be installed. If the bundle is not installed, the API returns 501 Feature Not Installed with instructions to install it via the admin UI.
The auto language option uses whisper's built-in language detection. Specifying the language explicitly improves accuracy and speed.
SRT is the most widely supported subtitle format. VTT (WebVTT) is the standard for web video players.
Progress updates are available via SSE at GET /api/v1/jobs/{jobId}/progress until the job completes.
