Description of your pull request and other information

I came across same company websites that provided videos via video-cdn.net, e.g. this. Some more can be found with the help of Google. The PR adds an extractor for those videos.

Thanks for your work!

I've made a few comments.

Also, if there's some standard embedding that's used with this host, that embedding should be supported in the generic extractor.

Also, if there's some standard embedding that's used with this host, that embedding should be supported in the generic extractor.

I see so many different ways videos from this cdn are embedded, e.g. via a clickable image without any hint on the 'player-id' or a div element with mi24-video-player video-id and player-id attribute or a div with data-video-id and data-player-id attributes. I think it'll be hard to maintain all those different embeddings. What do you think, @dirkf?

These pages don't even mention the video host in the non-JS HTML seen by yt-dl:

• https://www.db.com/what-next/digital-disruption/cloud/developers-Entwickler
• https://www.hella.com/techworld/de/Werkstattausruestung/Pruef-Einstellwerkzeuge/ADAS-Kalibrierung-8266/

This has each video link as the value of the src attribute of an <iframe>:

Embedded links of the above type could be extracted. yt-dl doesn't find links like this by default (#12692, #6216) but a lot of extractors are doing something similar:

In due course we'll follow this refactoring of the generic extractor from yt-dlp. If a routine is added for this case, it should use the APIs there, eg add a local IE with class property _EMBED_REGEX and (temporary) class method _extract_from_webpage(cls, url, webpage) that generates (or returns) the unique entries from the page, and call that method from a new fragment in the generic extractor.

You need to delete l.5 to pass the Linter test (done). Otherwise all good so far.

@dirkf Thank you for the linter fix!

So, should I provide additional code for the generic extractor to at least find the iframe embeddings in this PR?

[dirkf]

Up to you, really.
