--- title: "Third party" description: "Displaying the livechat with 3rd party software." weight: 20 chapter: false livechatnotranslation: true --- {{% notice warning %}} This page describes experimental features. These features are available with the plugin version >= 7.2.0. {{% /notice %}} ## Introduction Peertube is part of the Fediverse. So Peertube video can be watched from other Peertube instances, and from various other softwares: * from a Mastodon (or other fediverse application) instance, * from a mobile app (Fedilab, Tusky, ...), * from desktop fediverse app, * ... This livechat plugin is using well known standards, so it is possible to join chat rooms even when not viewing the video on Peertube. There are basically 2 ways to join the chat room associated to a video: * opening a web page (with an url like `https://yourinstance.tld/plugins/livechat/router/webchat/room/8df24108-6e70-4fc8-b1cc-f2db7fcdd535`), * using a XMPP client (and joining a room like `xmpp://8df24108-6e70-4fc8-b1cc-f2db7fcdd535@room.yourinstance.tld?join`) {{% notice warning %}} Joining the chat using a XMPP client is not always possible. It requires some DNS and server configuration. It will only be possible if instance's admins have correctly setup the [external XMPP clients connection](/peertube-plugin-livechat/documentation/admin/advanced/xmpp_clients/) feature. {{% /notice %}} {{% notice warning %}} Don't try to gues these url and connection methods yourself. Please report to next chapters. {{% /notice %}} ## Chat discovery ### Using ActivityPub The livechat plugin adds some data in Video ActivityPub objects, so that the chat can be discovered. {{% notice info %}} This requires Peertube >= 5.1 {{% /notice %}} This follows the [FEP-1970](https://codeberg.org/fediverse/fep/src/branch/main/fep/1970/fep-1970.md) recommendations. {{% notice warning %}} At the time of the writing, this FEP is in draft status, and the livechat plugin is a Proof-of-concept. Until the FEP is adopted, the specification can change, and the livechat plugin will be adapted accordingly. {{% /notice %}} Basically, the chat will be declared as `attachments` on the `Video` object, using the `discussion` relation. By default, here is an example of what you will get: ```javascript { "@context": [ "https://www.w3.org/ns/activitystreams", "https://w3id.org/security/v1", { "RsaSignature2017": "https://w3id.org/security#RsaSignature2017" }, { // ... } ], "to": [ "https://www.w3.org/ns/activitystreams#Public" ], "cc": [ "https://yourinstance.tld/accounts/root/followers" ], "type": "Video", "id": "https://yourinstance.tld/videos/watch/8df24108-6e70-4fc8-b1cc-f2db7fcdd535", "name": "The video title", // ... "url": [ /* ... */ ], "attachment": [ { "type": "Link", "name": "Chat for live stream: The video title", "rel": "discussion", "href": "https://yourinstance.tld/plugins/livechat/router/webchat/room/8df24108-6e70-4fc8-b1cc-f2db7fcdd535" } ] } ``` In case the instance has activated the [external XMPP clients connection](/peertube-plugin-livechat/documentation/admin/advanced/xmpp_clients/) feature: ```javascript { "@context": [ "https://www.w3.org/ns/activitystreams", "https://w3id.org/security/v1", { "RsaSignature2017": "https://w3id.org/security#RsaSignature2017" }, { // ... } ], "to": [ "https://www.w3.org/ns/activitystreams#Public" ], "cc": [ "https://yourinstance.tld/accounts/root/followers" ], "type": "Video", "id": "https://yourinstance.tld/videos/watch/8df24108-6e70-4fc8-b1cc-f2db7fcdd535", "name": "The video title", // ... "url": [ /* ... */ ], "attachment": [ { "type": "Link", "name": "Chat for live stream: The video title", "rel": "discussion", "href": "https://yourinstance.tld/plugins/livechat/router/webchat/room/8df24108-6e70-4fc8-b1cc-f2db7fcdd535" }, { "type": "Link", "name": "Chat for live stream: The video title", "rel": "discussion", "href": "xmpp://8df24108-6e70-4fc8-b1cc-f2db7fcdd535@room.yourinstance.tld?join" } ] } ``` #### Algorithm If you want to display the chat in a web page or in an iframe, here is what you should do: * get the Video ActivityPub object, * if there is no `attachment` key, stop. * loop through the `attachment` values (if `attachment` is not an array, just iterate on this single value) * search for an entry with `rel` === `discussion`, and with `href` using the `https` scheme (that begins with `https://`) * if found, open this href If you want to open the chat room using the XMPP protocol: * get the Video ActivityPub object, * if there is no `attachment` key, stop. * loop through the `attachment` values (if `attachment` is not an array, just iterate on this single value) * search for an entry with `rel` === `discussion`, and with `href` using the `xmpp` scheme (that begins with `xmpp://`) * if found, open this xmpp uri with your client, or connect to the XMPP room at that address #### Additional notes In the ActivityPub object, there is also a `peertubeLiveChat` entry. Don't use the content of this entry. This is specific to the livechat plugin, and can be changed or removed in a near future. It is currently required for some endpoint discovery. ### Using Podcast RSS feed The livechat plugin adds some data in Podcast RSS feeds under the [``](https://github.com/Podcastindex-org/podcast-namespace/blob/main/docs/1.0.md#live-item), so that the chat can be discovered for live streams. {{% notice info %}} This requires Peertube >= 5.2 {{% /notice %}} {{% notice info %}} The `` element is currently only supported for live streams. {{% /notice %}} This follows the [``](https://github.com/Podcastindex-org/podcast-namespace/discussions/502) proposal. {{% notice warning %}} At the time of the writing, this proposal is in draft status, and the livechat plugin is a Proof-of-concept. Until the proposal is adopted, the specification can change, and the livechat plugin will be adapted accordingly. {{% /notice %}} Basically, the chat will be declared as tag under on the `` element. By default, here is an example of what you will get: ```xml The video title e32b4890-983b-4ce5-8b46-f2d6bc1d8819_2023-07-06T18:00:00.000Z https://yourinstance.tld/videos/watch/8df24108-6e70-4fc8-b1cc-f2db7fcdd535 ``` In case the instance has activated the [external XMPP clients connection](/peertube-plugin-livechat/documentation/admin/advanced/xmpp_clients/) feature: ```xml The video title e32b4890-983b-4ce5-8b46-f2d6bc1d8819_2023-07-06T18:00:00.000Z https://yourinstance.tld/videos/watch/8df24108-6e70-4fc8-b1cc-f2db7fcdd535 ``` #### Algorithm If you want to display the chat in a web page or in an iframe, here is what you should do: * get the Podcast RSS feed for the channel, * if there is no `` element under the ``, stop. * find the `` you are looking for * `` can be used to cross-reference the items with ActivityPub * if there is no `` element under the ``, stop. * loop through the `` values (if `` is not an array, just iterate on this single value) * there should only be one, but you should expect to handle several just in case * search for the first entry `protocol` === `xmpp` and an `embedUrl` attribute * if found, open this embedUrl If you want to open the chat room using the XMPP protocol: * get the Podcast RSS feed for the channel, * if there is no `` element under the ``, stop. * find the `` you are looking for * `` can be used to cross-reference the items with ActivityPub * loop through the `` values (if `` is not an array, just iterate on this single value) * there should only be one, but you should expect to handle several just in case * search for the first entry `protocol` === `xmpp` and a `space` attribute * space should be an XMPP JID for a MUC * if found, open this XMPP JID with your client after converting it to a join URI, or connect to the XMPP room at that address
