Remote Comment capability

[drequivalent]

When I follow an account from Mastodon, I'm able to response only to new videos, that were uploaded since my server started federating with PeerTube.
I'd like to be able to comment on older videos, no matter if my instance is federating with PeerTube at the moment or not.

Correct me if I'm wrong, but I think ActivityPub doesn't allow you to do this in the way it works: it just emits metadata notifications for new content. For instance, you cannot get older toots on Mastodon after following somebody for the first time. (Maybe there's something to do at the standard specification level itself?)

[drequivalent]

Try to copy an URI of an old toot on an instance that does not federate with you to the search field. Mastodon will find this toot and let you respond.

[bnjbvr]

I see, makes sense.

[drequivalent]

It's kinda the same mechanism as with "Remote Follow", AFAIK.

I think this is a feature request on the Mastodon side 🤔

-> Recover old statuses through ActivityPub.

[drequivalent]

Will Mastodon implement a "Remote comment" link on Peertube pages? I don't think so.
Besides, why Mastodon? What if Pleroma or Aardwolf? Or another Peertube instance?

[Chocobozzz]

I'm sorry but I'm not sure to understand. I thought you wanted that on Mastodon, when you search a PeerTube video with its URL you have a result (which is not the case for now).

[drequivalent]

That would be a poor man's version of what I wanted.

What's better is "Remote comment" link right above the comments section which then asks for your Fediverse account and then redirects you to your Mastodon or whatnot with your video's page open ready for response.

[drequivalent]

Any news on this one?

[rigelk]

Maybe I'm mistaken but Mastodon, for instance, only supports follow and share intents (source).

There is mastodon/mastodon#916 tracking the implementation of such a feature.
I checked quickly on other fediverse software but couldn't find the feature either.

Any idea as to how to implement despite all of that, @drequivalent ?

Mastodon definitely shows me people's older posts from before I added them @bnjbvr

[ghost]

@leethax666 only on your own instance I think

@Chocobozzz I think the issue is that PeerTube is not giving JSON/XML AP responses for video links. https://github.com/tootsuite/mastodon/blob/master/app/services/fetch_atom_service.rb#L31-L32

A link such as https://peertube.cpy.re/videos/watch/da2b08d4-a242-4170-b32a-4ec8cbdca701 should have this in the HTML: <link rel=alternate type="application/atom+xml" href="..."> <link rel=alternate type="application/activity+json" href="..."> (make sure to update these links on navigation! I want to write a browser extension)

And respond to matching Accept: headers with the OStatus or ActivityPub views of the video.

This line in the router: https://github.com/Chocobozzz/PeerTube/blob/develop/server/controllers/client.ts#L19-L23 should be checking the Accept: header.

@riking I can only answer for the dynamic addition/removal of <link> entries during the navigation. Angular doesn't deal well with it. I grit my teeth trying to write it for feed autodiscovery. Here though, solving the problem of properly formating the header to respond to requests from Mastodon would only require to modify the generated header server-side (like you said, probably along those lines).

[Chocobozzz]

@riking Hello,

We give AP responses for video links: https://github.com/Chocobozzz/PeerTube/blob/develop/server/controllers/activitypub/client.ts#L44

Try

$ curl -H "Accept: application/ld+json" "https://peertube.cpy.re/videos/watch/5a6133b8-3e0c-40dc-b859-69d0540c3fe5"

For the HTML <link> you're right! I created a separate issue because as @rigelk said we are blocked by Angular.

[rigelk]

Now that Mastodon 2.5.0 implements remote reply/boost interactions through mastodon/mastodon#8202, at least we can redirect mastodon users to interact directly with the video.

[rigelk]

Implemented in 660d11e.

Consider removing

PeerTube/client/src/app/videos/+video-watch/comment/video-comments.component.html

Line 8 in 28da43c

customHtml="You can either comment on the page of your instance where this video is federated with your PeerTube account, or via any ActivityPub-capable fediverse instance. For instance with Mastodon or Pleroma you can type in the search box <strong>@{{video.account.name}}@{{video.account.host}}</strong> and find back the video. Direct commenting capabilities are being worked on in <a href='https://github.com/Chocobozzz/PeerTube/issues/224'>#224</a>."></my-help>

?

[rigelk]

@SerCom-KC on my todo 😉 I will integrate part of its content with the modal.
