Ingest

ingest

Thin yt-dlp wrapper. Atomic: one URL in, one source.mp4 + ingest.json out. Idempotent — if source.mp4 and ingest.json already exist for the same URL hash, skips the download.

Inputs

• url: video URL (required)
• id (optional): source id slug; defaults to a short sha1 of the URL
• workdir (optional): root work directory; defaults to ./work

Output

• ./work/<id>/source.mp4 — the downloaded video, mp4 container
• ./work/<id>/ingest.json — metadata, shaped as:

{
  "id": "<id>",
  "url": "<url>",
  "title": "...",
  "duration": 183.4,
  "fps": 30.0,
  "width": 1920,
  "height": 1080,
  "path": "work/<id>/source.mp4"
}

How

1. Compute id from URL (sha1(url)[:10]) if not given.
2. mkdir -p work/<id>.
3. yt-dlp -f 'bv*+ba/b' --merge-output-format mp4 --embed-metadata --print-to-file '%(title)s' work/<id>/.title.txt -o 'work/<id>/source.%(ext)s' <url>
4. ffprobe -v error -print_format json -show_format -show_streams work/<id>/source.mp4 → extract duration, fps, width, height.
5. Title comes from yt-dlp's .title.txt (merged-mp4 container tags are unreliable and often empty); falls back to the container title tag.
6. Write ingest.json.
