I am facing a challenge in figuring out how to capture a video using openCV. While I have managed to display the video on an html template with the existing codes, I am uncertain about which codes are needed to actually record the video.
-camera.py-
import cv2
class VideoCamera(object):
def __init__(self):
self.video =cv2.VideoCapture(1)
def __del__(self):
self.video.releast()
def get_frame(self):
ret, frame = self.video.read()
ret, jpeg = cv2.imencode('.jpg' , frame)
return jpeg.tobytes()
-main.py-
from camera import VideoCamera
@app.route("/Record", methods=['GET', 'POST'])
def Record():
#return Response(generate_frames(), mimetype='multipart/x-mixed-replace; boundary=frame')
return render_template('record.html')
def gen(camera):
while True:
frame = camera.get_frame()
yield (b' --frame\r\n'
b'Content-Type: image/jpeg\r\n\r\n' + frame
+ b'\r\n\r\n')
@app.route('/video_feed')
def video_feed():
return Response(gen(VideoCamera()), mimetype='multipart/x-mixed-replace; boundary=frame')
-record.html-
<body>
<img id="bg" src="{{ url_for('video_feed') }}">
</body>
