How to display video from RTSP link?

Using Streamlit
1

Hey, guys!

I’m trying to display a realtime video in a streamlit application from an RTSP link. I know I can use opencv to process it, but I can’t display it. Do you have any idea how I can do this? Below is a code I’ve already tried.

import cv2
import numpy as np
import streamlit as st

# Function to capture frames from an RTSP stream
def capture_frames(rtsp_url):
    cap = cv2.VideoCapture(rtsp_url)

    while cap.isOpened():
        ret, frame = cap.read()
        if not ret:
            break

        # You might want to resize the frame here if it's too large for display
        frame = cv2.resize(frame, (640, 480))

        yield frame

    cap.release()

# Streamlit app
def main():
    st.title('RTSP Stream Player')

    rtsp_url = st.text_input('Enter RTSP stream URL')

    if rtsp_url:
        st.text('Streaming from: ' + rtsp_url)

        # Create a VideoCapture generator
        frame_gen = capture_frames(rtsp_url)

        # Display the frames using Streamlit
        while True:
            frame = next(frame_gen)
            st.image(frame)

if __name__ == '__main__':
    main()
