Summary

🛠️📺🆔

Improved extraction for MediaKlikk videos. The extractor now uses a better way to find the playlist url, updates the tests with fresh data, and adds a new field for the video identifier.

The MediaKlikkIE extractor
Was not very good at its factor
So it got a new way
To find the playlist url
And also a nice display_id actor

Walkthrough

• Add display_id field to info_dict of test cases and derive it from url path (link, link)
• Update test cases with new urls, ids, upload_dates and thumbnails that match current website layout and content (link)
• Extract playlist url from player json using traverse_obj and url_or_none instead of regex and raise error if invalid (link, link)

Old tests:

1. Dead URL, opens a 404 page. Fixed with a newer video
2. Dead URL, opens a 404 page. Fixed with a newer video
3. Live URL. Fixed with extra info
4. Dead URL, opens the video list page. Fixed with a newer video
5. Dead URL, opens an empty page. Fixed with a newer video

Good job finding some new tests.

However, the old tests have some URL formats that we still want to test for matching.

Instead of replacing the dead tests, we should add skip keys to the dead tests, and add the new tests below them. The value for the skip key should be the reason why we are skipping, e.g.

    }, {
         'url': 'https://...',
         'info_dict': {
             'id': '...',
         },
+        'skip': 'Webpage redirects to videos list',
    }, {
