1 | ## Live Streaming with Flask and Open-CV
2 | ```python
3 | pip install -r requirements.txt
4 | ```
5 | ### Run Server
6 | ```python
7 | python app.py
8 | ```
9 | #### Use Built-in Webcam of Laptop
10 | ##### Put Zero (O) in cv2.VideoCapture(0)
11 | ```python
12 | cv2.VideoCapture(0)
13 | ```
14 | #### Use Ip Camera/CCTV/RTSP Link
15 | ```python
16 | cv2.VideoCapture('rtsp://username:password@camera_ip_address:554/user=username_password='password'_channel=channel_number_stream=0.sdp')
17 | ```
18 | #### Example RTSP Link
19 | ```python
20 | cv2.VideoCapture('rtsp://mamun:123456@101.134.16.117:554/user=mamun_password=123456_channel=0_stream=0.sdp')
21 | ```
22 | #### Change Channel Number to Change the Camera
23 | ```python
24 | cv2.VideoCapture('rtsp://mamun:123456@101.134.16.117:554/user=mamun_password=123456_channel=1_stream=0.sdp')
25 | ```
26 | #### Display the resulting frame in browser
27 | ```python
28 | cv2.imencode('.jpg', frame)[1].tobytes()
29 | ```
30 | ## Or this one
31 |
32 | ```python
33 | net , buffer = cv2.imencode('.jpg', frame)
34 | buffer.tobytes()
35 | ```
