How to parse mjpeg http stream from ip camera in python?

To parse an MJPEG HTTP stream from an IP camera in Python, you can use the requests library to fetch the stream and the cv2 library from OpenCV to process and display the frames. Here's a basic example of how to achieve this:

  • Install the required libraries:

You'll need to install the requests and opencv-python libraries if you haven't already. You can install them using the following commands:

pip install requests pip install opencv-python
  • Fetch and Parse MJPEG Stream:

Here's a sample script to fetch and parse an MJPEG stream from an IP camera using Python:

import cv2 import requests import numpy as np # IP camera MJPEG stream URL mjpeg_url = "http://your_ip_camera_url/stream.mjpg" # Open the MJPEG stream response = requests.get(mjpeg_url, stream=True) if response.status_code != 200: print("Failed to open MJPEG stream") exit() # Function to read and display frames def show_mjpeg_stream(): bytes_stream = bytes() for chunk in response.iter_content(chunk_size=1024): bytes_stream += chunk a = bytes_stream.find(b'\xff\xd8') b = bytes_stream.find(b'\xff\xd9') if a != -1 and b != -1: jpg = bytes_stream[a:b + 2] bytes_stream = bytes_stream[b + 2:] frame = cv2.imdecode(np.frombuffer(jpg, dtype=np.uint8), cv2.IMREAD_COLOR) cv2.imshow('IP Camera Stream', frame) if cv2.waitKey(1) & 0xFF == ord('q'): break # Show the MJPEG stream show_mjpeg_stream() # Release resources cv2.destroyAllWindows() response.close()

Replace "http://your_ip_camera_url/stream.mjpg" with the actual URL of your IP camera's MJPEG stream.

Keep in mind that this example provides a basic way to fetch and display the MJPEG stream. Depending on your requirements, you might want to handle error cases, optimize the processing, and potentially use threading or multiprocessing to enhance the performance of the stream parsing and display.

Also, remember that MJPEG streams can vary in their format and behavior based on the camera's implementation, so you might need to adjust the code according to your specific camera's behavior.
