Summary

🆕🛠️🧹

Improved and fixed RbgTumIE and RbgTumCourseIE extractors to handle new domain and URL formats. Added tests and refactored code for clarity and robustness.

Oh we are the coders of the tum.live domain
We extract the videos with skill and with brain
We fix the URLs and we test every case
We heave away and haul away and keep up with the pace

Walkthrough

• Update the RbgTumIE and RbgTumCourseIE extractors to support the new domain tum.live as an alternative to live.rbg.tum.de (link, link)
• Fix the extraction of some videos that have a query string in their m3u8 URL by including the optional query string in the _html_search_regex call for the m3u8 variable in the RbgTumIE extractor (link)
• Use the hostname variable from the _match_valid_url call instead of hardcoding the live.rbg.tum.de domain in the RbgTumCourseIE extractor, to make it more flexible and consistent with the RbgTumIE extractor (link, link)
• Add test cases to the RbgTumIE and RbgTumCourseIE extractors to check the extraction of videos and courses from the new domain tum.live (link, link)

I can see a few issues in the IE unrelated to your PR. I'll refrain from suggesting changes for them unless you are interested in looking at them.

Ok, it seems like there was a big change to the website layout yesterday, I have to adopt it now.

The new ui should be working, a new json extractor added, with the old html parser as backup
