Question

I used youtube-dl with proxy server to get json output in my python program. I found my proxy server was called 3 times.

def parse_url(url):
    
    ydl_options = {
        "dump_single_json": True,
        "proxy": "http://xxxxxxx:80",
        "nocheckcertificate": True }
    
    with youtube_dl.YoutubeDL(ydl_options) as ydl:
        try:
            info = ydl.extract_info(url, download=False)
            return info
        except Exception as e:
            return {'error': str(e)}

However, if I call youtube-dl in my terminal like this:

youtube-dl -J https://www.youtube.com/watch?v=aFkcAH-m9W0 --proxy http://xxxxxxx:80

I tested that my proxy server was only called once.

How can I modify my python code to only call proxy server once?
