1 | ## Distributed Live Streaming with ZeroMQ and Flask Socket Connection
2 |
3 | ```python
4 | pip install requirements.txt
5 |
6 | ```
7 | ### Run Server
8 | ```python
9 | python main.py
10 | ```
11 | ```python
12 | python client.py
13 | ```
14 | ### Now Browse
15 | - [http://127.0.0.1:5000/](http://127.0.0.1:5000/)
16 |
17 | #### Use Built-in Webcam of Laptop
18 | ##### Put Zero (O) in cv2.VideoCapture(0)
19 | ```python
20 | cv2.VideoCapture(0)
21 |
22 | ```
23 | #### Use Ip Camera/CCTV/RTSP Link
24 | ```python
25 | cv2.VideoCapture('rtsp://username:password@camera_ip_address:554/user=username_password='password'_channel=channel_number_stream=0.sdp')
26 |
27 | ```
28 | #### Example RTSP Link
29 | ```python
30 | cv2.VideoCapture('rtsp://mamun:123456@101.134.16.117:554/user=mamun_password=123456_channel=0_stream=0.sdp')
31 |
32 | ```
33 | #### Change Channel Number to Change the Camera
34 | ```python
35 | cv2.VideoCapture('rtsp://mamun:123456@101.134.16.117:554/user=mamun_password=123456_channel=1_stream=0.sdp')
36 |
37 | ```
38 | #### Display the resulting frame in browser
39 | ```python
40 | cv2.imencode('.jpg', frame)[1].tobytes()
41 |
42 | ```
