Support for networked cameras via RTSP protocol?

j_b · October 22, 2021, 7:37pm

I’ve been working with Mycodo for about a month now and may have missed how to interact with networked cameras via RTSP. I am currently using urllib camera module, pointing to single snapshot rather than it capturing the continuous stream. Am I missing how to connect via RTSP or would this need to be a new feature request?

I’m not familiar with RTSP, but I’m sure it could be implemented. I also don’t have any networked cameras.

Support for IP cameras in general would be wonderful. I’ve got existing cameras that it’d be great to integrate.

What I’m using is old smartphone with good camera and an app called IP cam or something similar, turning the phone in to easily accessible cam. I’ve tried the stream option and it works, it’s just a bit harsh on the zero 2, forcing it to restart and rising temp to nearly 60C.

Hello everyone,

I found a solution for this, a bit cumbersome but it works.

github.com

cwk9/rtsp_screenshot/blob/82ca9a8ad853db51d4231e403bcc48c4fd034aa3/rtsp_screenshot.py

#!/usr/bin/env python3
#Grab an image from an RTSP Stream. 
#Returns cv2 image as numpy.ndarray. Can be written file using opencv.
#Example
#newimage = rtsp_screenshot(ipcam = '192.168.1.123', username = 'admin', password = 'yourpw', port = '554')
#cv2.imwrite('testimg.jpg',newimage)
import cv2 #open-cv lib is needed for RTSP stream.
import os
import sys
from copy import deepcopy

def rtsp_screenshot(ipcam = '', username = '', password = '', port = '554'):
#    ipcam = '' #list of hosts to grab data from.
#    username = ''
#    password = ''
#    port = '554' #udp port number

    try:
        if username != '' or password != '': 
            RTSP_URL = 'rtsp://' + username + ':' + password + '@' + ipcam + ':' + port

I have configured a cronjob on the pi that creates a new image of the stream in current.jpg every two minutes

Then I created an extra listening port in the nginx configuration (e.g. 88) and rooted the site to the folder where the image is stored.

You can then refer to adres:88/current.jpg via the URL request camera module
