Giorgio Gilestro 3f0760c98e Picker: simpler keyboard shortcuts (±5 s / ±30 s) 
Dropped Ctrl+arrow (±0.1 s) and ,/. frame stepping — too fine for
spotting the barrier opening visually. Shift+arrow now jumps ±30 s
instead of ±1 s, which matches how analysts actually navigate (5 s
for fine, 30 s for skipping ahead). Drag the seekbar if you need
sub-second precision.

Cupido — web-based barrier-opening picker

A small FastAPI + HTML5-video app for annotating the barrier-opening moment in each tracked recording. Lives in its own Docker container so it can run on the lab server without polluting any existing environment.

What it does

For every video referenced by all_video_info_merged.tsv that has a tracking DB on disk and isn't yet in barrier_opening.csv, it serves a <video> element pre-loaded with that mp4. The analyst plays / scrubs / pauses at the moment the barrier opens, then clicks one of:

button meaning written to bad_rois
All barriers open every ROI (1..6) is usable post-opening empty
Upper barriers open only the top row opens (ROIs 1, 3, 5) 2,4,6
Lower barriers open only the bottom row opens (ROIs 2, 4, 6) 1,3,5

Plus a Skip (advance without saving) and Unusable (write opening_s = NaN).

Keyboard shortcuts

  • Space — play / pause
  • ← / → — ±5 s
  • Shift+arrows — ±1 s
  • Ctrl+arrows — ±0.1 s
  • , / . — ±1 frame
  • 1 / 2 / 3 — All / Upper / Lower
  • s — skip ; u — unusable

Run locally (docker compose)

cd scripts/barrier_picker_app
docker compose up --build

Then browse to http://localhost:8000/.

The container mounts:

  • /mnt/data/projects/cupido (data volume, read-only)
  • /mnt/ethoscope_data/videos (source mp4s, read-only)
  • data/metadata/ from the repo (read-write — for persisting barrier_opening.csv)

Adjust paths in docker-compose.yml if your layout differs.

Run without Docker (development)

cd scripts/barrier_picker_app
pip install -r requirements.txt
python app.py     # serves on http://localhost:8000

By default it expects:

  • merged TSV at /mnt/data/projects/cupido/all_video_info_merged.tsv
  • inventory at /cupido/data/metadata/video_inventory.csv
  • writes to /cupido/data/metadata/barrier_opening.csv

Override via environment variables:

CUPIDO_DATA_VOLUME=/path/to/data \
CUPIDO_INVENTORY_CSV=$(pwd)/../../data/metadata/video_inventory.csv \
CUPIDO_OUTPUT_CSV=$(pwd)/../../data/metadata/barrier_opening.csv \
python app.py
