This project is on-going, is hosted on PeerTube, and we aren’t too far behind, so I thought it might be of interest.

    Subscribing to his channel from Lemmy never even occurred to me (?!)

    Now is as good a time as any though to investigate Lemmy/PeerTube interactions:

    The search that lemmy will do:
    curl --header 'accept: application/activity+json' https://diode.zone/.well-known/webfinger?resource=acct:andybalaam_lectures@diode.zone | jq .
    The ‘activity+json’ links section reveals that the url is https://diode.zone/video-channels/andybalaam_lectures

    ‘Click’ on that:
    curl --header 'accept: application/activity+json' https://diode.zone/video-channels/andybalaam_lectures | jq .
    Interesting parts:
    ‘type’ is Group, which is what lemmy uses for communities
    there’s no ‘moderators’ link, so that’ll be empty on the community page
    ‘outbox’ is at https://diode.zone/video-channels/andybalaam_lectures/outbox which lemmy should be able to use to fetch the recent videos. It doesn’t work because community outboxes on Lemmy just list the last 20 posts directly, whereas PeerTube (and Mastodon) redirect you to a ‘outbox?page=1’ url.
    ‘playlists’ is at https://diode.zone/video-channels/andybalaam_lectures/playlists, which is what we want really (the Rust 101 playlist)
    These are of type Playlist though, which Lemmy doesn’t know what to do with.

    Following the ‘playlist’ link:
    –> https://diode.zone/video-channels/andybalaam_lectures/playlists?page=1 (posts 1 to 10)
    –> https://diode.zone/video-channels/andybalaam_lectures/playlists?page=2 (post 11)

    Bash script to get the URLs

    #!/bin/bash

curl --silent --header 'accept: application/activity+json' "https://diode.zone/video-playlists/fcec1b54-0908-452e-9d35-84c9627c3b50?page=1" > /tmp/page1.json
curl --silent --header 'accept: application/activity+json' "https://diode.zone/video-playlists/fcec1b54-0908-452e-9d35-84c9627c3b50?page=2" > /tmp/page2.json

for i in {0..9}
do
    item=$(jq -r ".orderedItems[$i]" /tmp/page1.json)
    url=$(curl --silent --header 'accept: application/activity+json' "$item" | jq -r .url)
    sleep 1.1s
    echo $url
done

item=$(jq -r ".orderedItems[0]" /tmp/page2.json)
url=$(curl --silent --header 'accept: application/activity+json' "$item" | jq -r .url)
echo $url

    gives us:

    I used endlesstalk.org’s Search to bring most of these through, before getting bored and using the API. e.g.:

    curl --request GET \
     --url 'https://endlesstalk.org/api/v3/resolve_object?q=https://diode.zone/videos/watch/03735b5f-8ace-411c-998e-7c4a58a11914' \
     --header 'accept: application/json' \
     --header 'authorization: Bearer $MY_JWT_TOKIN'

    So the bash script could easily be modified to resolve everything as well.
