Flask-OpenCV-Streamer

A Python package for easily streaming OpenCV footage, even with authentication

Installation

Install via PyPi using Pip / PipEnv:

pip install flask_opencv_streamer

Usage

Usage is quite straight forward. After importing, you can create as many streamer objects as you wish.

Example Code:

Without authentication (no login required to view page)

from flask_opencv_streamer.streamer import Streamer
import cv2

port = 3030
require_login = False
streamer = Streamer(port, require_login)

# Open video device 0
video_capture = cv2.VideoCapture(0)

while True:
    _, frame = video_capture.read()

    streamer.update_frame(frame)

    if not streamer.is_streaming:
        streamer.start_streaming()

    cv2.waitKey(30)

With authentication (A password will be generated for you, expiring every 24 hrs)

from flask_opencv_streamer.streamer import Streamer
import cv2

port = 3030
require_login = True
login_file = "logins.txt"
login_key = "loginkey.txt
streamer = Streamer(port, require_login, login_file=login_file, login_key=login_key)

# Open video device 0
video_capture = cv2.VideoCapture(0)

while True:
    _, frame = video_capture.read()

    streamer.update_frame(frame)

    if not streamer.is_streaming:
        streamer.start_streaming()

    cv2.waitKey(30)

If there is no logins file or key found at the path given, it will create one for you. Logins will be stored in a .txt file logins.txt but will be encrypted. Therefore, unless someone has the key (in this example, loginkey.txt) the logins.txt file will be able to show logins or passwords. It is very unsafe to keep the login key somewhere publicly accessible; it's suggested you hide it well and do not upload it anywhere.

Adding or removing your own logins

In your root project directory, you can include a templates folder which can be used for password change templates. Your file names must be:

• form.html: Contains the HTML form for the password change.
• pass.html: Contains the HTML for a pass event
• fail.html: Contains the HTML for a fail event
