Retry when connection disconnect not working

I am using youtube-dl for downloading the videos from YouTube. But in my office the internet will disconnect every 20Mb of download. [Error: Connection forcibly closed by remote server].

I have to type the URL again to resume the download and again it will disconnect after '20Mb' I want youtube-dl to reconnect and retry to download the file.

I tried using --retries switch but it is not retrying once disconnected.

Is there any inbuild method or Work around for this?

Solution

Educated guess

My best guess would be to specify a cache directory, and use the -c flag to force it to continue downloads if possible.

Source: youtube-dl man page

--cache-dir DIR
              Location  in  the  filesystem  where  youtube-dl  can  store  some  downloaded  information  permanently.   By  default
              $XDG_CACHE_HOME  /youtube-dl or ~/.cache/youtube-dl .  At the moment, only YouTube player files (for videos with obfus‐
              cated signatures) are cached, but that may change.

-c, --continue
              Force resume of partially downloaded files.  By default, youtube-dl will resume downloads if possible.

Alternative solution

If you want to give python a try, this script should do what you need with some minor tweaking.

import sys
import youtube_dl

def download_no_matter_what(url):
    try:
        youtube_dl.YoutubeDL(options).download([url])
    except OSError:
        download_no_matter_what(url)
    except KeyboardInterrupt:
        sys.exit()

if __name__ == '__main__':
    # Read the URL from the command line
    url = sys.argv[1]

    # Specify extra command line options here
    options = {} 

    # GET THAT VIDEO! 
    download_no_matter_what(url)
