Site support Request: Realm.io Videos

[aaronvegh]

Up till a couple weeks ago, Realm hosted their videos on Youtube, but they've now switched to Wistia. Here's an example page: https://realm.io/news/alexis-gallagher-3d-touch-swift/

Well, Wistia should already be supported, according to supportedsites.md

Edit:

Here is a link I found manually:
https://embed-ssl.wistia.com/deliveries/b7835fb9475ffcd2c117004ffa9005fd32c8872e.bin

Is that the video you wanted?

[aaronvegh]

I'm not really interested in the video per se; I'm looking to ensure that Youtube-DL can support videos on this site. I think the reason it can't find the video is that Realm is injecting the video tags after the page loads using Javascript. I don't know if Youtube-DL supports loading JS and pulling video data that way, but it should because several sites that I've run into do just that.

[Hrxn]

Which site?
Realm.com (Issue title) or Realm.io (Example link)?

Because realm.io doesn't look like a video site to me, how many videos are accessible there?

But you are right otherwise, the video embed isn't there initially, only after clicking that 'Play' symbol on the video..

[aaronvegh]

Yikes, sorry about that. It's realm.io, the mobile database developer. For some reason they publish a series of technical talk videos for iOS developers, so a naive visitor to the site wouldn't know they did such a thing. However, videos like those linked in my original are super-popular among developers. It seems they link primarily from their News page: https://realm.io/news/.

[Hrxn]

Okay, sounds interesting..

There are not that many videos there, I would assume, but it would be nice to get them easily, I agree..
So, if someone has the necessary time and skills to write a new information extractor, please go ahead.

BTW:

Mobile database? So, I can't use that database for a web application, a desktop app, or just as the database for my website backend? 😉

This seems to be related to #8347. The issue is that the embedded videos on the site are not detected. Example https://realm.io/news/benji-encz-unidirectional-data-flow-swift/

Here is another example video on realm.io where the download attempt fails. Any news meanwhile?

Another video link for you to test the implementation with.
