    if(option=="Video 1"):
        output_url='Videos\output_1.avi'
        input_url='Videos\1.mp4'
        #return redirect(url_for('Display_video', input_url=input_url,output_url=output_url))
    elif(option=="Video 2"):
        output_url='Videos\output_2'

    elif(option=="Video 3"):
        output_url='Videos\output_3'
        input_url='Videos\3.mp4'

Videos are stored in videos folder in project folder D:\Web-page\Videos

Displays Social_distanc_detection.html, but on clicking submit gives 405: The method is not allowed for the requested URL error

python html flask

Solution 1:^[1]

It seems that when you submit, it's trying to send a POST request to the social_distance_detection route (/) which is only set up for GET requests.

You could try putting this in your <form> tag:

action="/Display_video" method="get"

<form> tag documentation
