1 | # Live-Streaming-using-OpenCV-Flask
2 | A Flask Web-App to stream live from local webcam or CCTV (rtsp link)
3 |
4 | ## Use Built-in Webcam of Laptop
5 |
6 | ### Put Zero (O) in cv2.VideoCapture(0)
7 |
8 | ``` cv2.VideoCapture(0) ```
9 |
10 | ### Use Ip Camera/CCTV/RTSP Link
11 | ``` cv2.VideoCapture('rtsp://username:password@camera_ip_address:554/user=username_password='password'_channel=channel_number_stream=0.sdp') ```
12 |
13 | ### Example RTSP Link
14 | ``` cv2.VideoCapture('rtsp://mamun:123456@101.134.16.117:554/user=mamun_password=123456_channel=0_stream=0.sdp') ```
15 |
16 | ### Change Channel Number to Change the Camera
17 | ``` cv2.VideoCapture('rtsp://mamun:123456@101.134.16.117:554/user=mamun_password=123456_channel=1_stream=0.sdp') ```
18 |
19 | ### Display the resulting frame in browser
20 | ``` cv2.imencode('.jpg', frame)[1].tobytes() ```
21 |
22 | ### Or this one
23 | ```
24 | net , buffer = cv2.imencode('.jpg', frame)
25 | buffer.tobytes()
26 | ```
