1 | ## Video Streaming with Flask Example
2 |
3 | ### Website
4 | http://www.chioka.in
5 |
6 | ### Description
7 | Modified to support streaming out with webcams, and not just raw JPEGs.
8 |
9 | ### Credits
10 | Most of the code credits to Miguel Grinberg, except that I made a small tweak. Thanks!

12 |
13 | ### Usage
14 | 1. Install Python dependencies: cv2, flask. (wish that pip install works like a charm)
15 | 2. Run "python main.py".
16 | 3. Navigate the browser to the local webpage.

3 | class VideoCamera(object):
4 | def __init__(self):
5 | # Using OpenCV to capture from device 0. If you have trouble capturing
6 | # from a webcam, comment the line below out and use a video file
7 | # instead.
8 | self.video = cv2.VideoCapture(0)
9 | # If you decide to use video.mp4, you must have this file in the folder
10 | # as the main.py.
11 | # self.video = cv2.VideoCapture('video.mp4')
12 |
13 | def __del__(self):
14 | self.video.release()
15 |
16 | def get_frame(self):
17 | success, image = self.video.read()
18 | # We are using Motion JPEG, but OpenCV defaults to capture raw images,
19 | # so we must encode it into JPEG in order to correctly display the
20 | # video stream.
21 | ret, jpeg = cv2.imencode('.jpg', image)
22 | return jpeg.tobytes()
