Cannot download video from udemy

See original GitHub issue

Hi there, I got 403 error when downloading course from udemy business. I used command: yt-dlp -u udemy@abc.com -p password -P '~/Downloads' -o '%(playlist)s/%(chapter_number)s - %(chapter)s/%(title)s.%(ext)s' https://abc.udemy.com/course/ielts-vocab-builder-002/ I’m sure that the username/password in command is correct. Please see the log:

Account shared. Answer from pukkandan: Cloudflare captcha is causing the issue. Will need to investigate further to find a solution

I want to watch Udemy video on mpv for studying and note-taking. I tested 2022.06.29 and found some issues and workaround.

        def is_logged(webpage):
            return any(re.search(p, webpage) for p in (
                r'href=["\'](?:https://www\.udemy\.com)?/user/logout/',
                r'>Logout<',
                r'"is_authenticated":true', # added
                fr'"email":"{username}"')) # added

Udemy login popup is updated. So it needs to be updated. But after a few successful logins, I couldn’t log in. Udemy just returnend the login popup html. I don’t know why. Maybe Udemy restriction?

Captcha page of cloudflare is changed. yt-dlp needs to be updated in udemy.py:L132-L139

        if any(p in webpage for p in (
                '>Please verify you are a human',
                'Access to this page has been denied because we believe you are using automation tools to browse the website',
                '"_pxCaptcha"',
                'cf-captcha-container')): # added
            raise ExtractorError(
                'Udemy asks you to solve a CAPTCHA. Login with browser, '
                'solve CAPTCHA, then export cookies and pass cookie file to '
                'yt-dlp with --cookies.', expected=True)

The course id is wrong in udemy.py:L205

    def _real_extract(self, url):
        lecture_id = self._match_id(url)

        webpage = self._download_webpage(url, lecture_id)

        course_id, _ = self._extract_course_info(webpage, lecture_id)
        #course_id = "3833504" # If I pass correct course id, it would get correct lecture info.

        try:
            lecture = self._download_lecture(course_id, lecture_id)

_real_extract passes wrong course_id to _download_lecture. It always gets 403 Forbidden. If course_id is correct, yt-dlp will download video properly. I wanted to make a PR but I couldn’t fix the 3 because I couldn’t pass playlist url which has real course_id to _real_extract.
