Now click on My Courses in the Udemy navbar and refresh the page you will see some requests under Network Tab. Right click on request links to udemy.com/api-2.0/. Simply copy Request Headers and save to text file.

These instructions really are not clear. I would suggest to improve "Right click on request links to udemy.com/api-2.0/" to specify which request link to udemy.com/api-2.0/ - if any one is OK, then specify that. "Simply copy Request Headers and save to text file.": there are Request Headers displayed lower down in Dev Tools. To specify that you can save the headers via the right click context menu: "Right click on... and select 'Copy Request Headers' from the context menu". "and save to text file." -> "The headers are now in the clipboard. Paste them into a text file and save it to the udemy-dl directory"

So far so good?

Now the next point I cannot suggest a phrasing for as I could not work out what the instruction is trying to do. "Done run the udemy-dl against that text file it will start downloading the course."

What does it mean to run udemy-dl "against" a text file? I cannot see any option to use a text file as parameters to udemy-dl .

Hi!

just as the title mention, i have an error when i try to download course. "Udemy Says : 403 Forbidden retry after few minutes" Does anyone has the same error ?

Describe the bug Sometimes files with py, json, and text extension are skipped from being downloaded

To Reproduce Steps to reproduce the behavior:

1. udemy course url: https://www.udemy.com/course/python-for-beginners-learn-python-from-scratch
2. Run the following command to reproduce the error... python udemy-dl.py https://www.udemy.com/course/python-for-beginners-learn-python-from-scratch/ -k cookie.txt -u my_emails_address -p my_password -q 1080 -o "../Udemy_-_Python_3_from_Beginner_to_Expert_-_Learn_Python_from_Scratch" --skip-sub

Additional context First time seeing this occur and only with this course. Some of the py and txt files did download, but most were skipped. All naming conventions were the same for files successfully downloaded and for those that were skipped. I manually downloaded a few of the files being skipped and opened them in vs codium. I didn't see any issues with contents of files i.e. not corrupt or empty files. Any suggestions? Update: It's happening on https://www.udemy.com/course/docker-tutorial/ as well.

Update - i tried this same command on another course i have in my account and didnt got error on it . I dont know if that matters but this course on which i have got this error is kinda big in size - it has 41 chapters/sections and 405 lectures

Describe the bug Hello udemy-dl team. I downloaded the update that was released 10 days ago because when I download it, it sends me the message: Udemy Says: 403 Forbidden You should use cookie base method to authenticate or try again in a few minutes.

To Reproduce I have followed the guide written by the admin in the league for Google Chrome https://github.com/r0oth3x49/udemy-dl/issues/389 and I have created a file named cookies.txt

I have followed the 2 options available:

$ python udemy-dl.py https://www.udemy.com/course/universidad-python-desde-cero-hasta-experto-django-flask-rest-web/ --info -k cookies.txt

$ python udemy-dl.py -u [email protected] -p password https://www.udemy.com/course/universidad-python-desde-cero-hasta-experto-django-flask-rest-web/ - k cookies.txt

I don't get a successful result :(

Download a course fails with the current Git master (f5623f1195bfabf29467367ed47923afe03c944a). Login works fine, the overview pages are also fetched and with --sub-only I get the subtitle. But every video download is skipped with URLError : either your internet connection is not working or server aborted the request.

The course doesn't matter, but I just reconfirmed the problem with this free course: https://www.udemy.com/become-an-options-trading-expert/

Is there any way to make udemy-dl more verbose? Let me know if there are any other means for me to help in debuging.

When i'm trying to download any course any videos that have their URLs starting in blob:https://URL_UDEMY are being skipped.

the lectures are recognized but only assets in that chapter are downloaded. I have all requirements including ffmpeg installed & working in command line.
