Peertube support

[fgaz]

Problem

I'd like to set video urls to peertube videos and get the same functionality as youtube:

• thumbnail
• embed

Solutions

Implementing this isn't as straightforward as youtube.

• Requires detecting peertube instances, either through a hardcoded list or by querying /.well-known or /api
• The thumbnail url can't be trivially derived from the video id. It requires a call to /api/v1/videos/{id} to get thumbnailPath, which might have to be cached in the database to avoid calling the peertube API on every request.
• There might be security implications stemming from embedding arbitrary pages. An instance whitelist might be safer.

Alternatives

...don't

Additional context

Package with a peertube video: https://content.luanti.org/packages/fgaz/last_login_signs/

Maybe I could show the og:image of linked pages. I don't really want to add support for embedding lots of different video providers

I looked into opengraph video embeds, and it looks like it's safer than I thought. Mastodon for example embeds any video by putting twitter:player/og:video/og:video:url in an iframe like this

<iframe
  width="560" height="315"
  src="https://video.hardlimit.com/videos/embed/jNYwGM2QCqNCvykBmfBs1M?autoplay=1&amp;auto_play=1"
  frameborder="0" allowfullscreen=""
  sandbox="allow-scripts allow-same-origin allow-popups allow-popups-to-escape-sandbox allow-forms"
