Pynopticon

Pynopticon is a video recording utility that saves the last n frames before an interesting event to disk. This is useful if you just want to record the frames leading up to an interesting event.

import time
from pynopticon import Pynopticon

p = Pynopticon(record_frames=100)
p.start()
time.sleep(10)
p.save()

Optionally, you can upload the video to YouTube. This requires a client_secrets.json file, see instructions here.

import time
from pynopticon import Pynopticon, get_authenticated_service

youtube = get_authenticated_service(client_secrets_file="./client_secrets.json")
p = Pynopticon(record_frames=100, youtube=youtube)
p.start()
time.sleep(10)
p.save(upload=True, title="My Video", description="My Description")

There is also a server that exposes an http api, in case if you want to run Pynopticon on an external device.

# without upload:
python -m pynopticon

# with upload:
CLIENT_SECRETS_FILE="client_secrets.json" python -m pynopticon

api:

• /: visit in browser for live streaming
• POST /start: same as p.start() (after stop, server auto starts pynopticon instance)
• POST /save: same as p.save(). Set ?upload=true to upload to YouTube. Only works if CLIENT_SECRETS_FILE is set.
• POST /stop: same as p.stop()

config:

• RECORD_FRAMES: number of frames to record before an event. Default: 100
• CLIENT_SECRETS_FILE: path to client_secrets.json file. Default: None
• PORT: port to run server on. Default: 4004
• HOST: host to run server on. Default: 0.0.0.0
• CAM: camera index. Default: 0
