Migrate PeerTube RSS feeds to podcast feeds

[Chocobozzz]

Hi,

The next PeerTube version (7.1) will have a better support of podcast feed for channels: https://peertube2.cpy.re/feeds/podcast/videos.xml?videoChannelId=31158

Unfortunately, the podcast index seems to index many PeerTube channels using the classic videos media feed: https://peertube2.cpy.re/feeds/videos.xml?videoChannelId=31158

This feed doesn't favor the audio file for the default <enclosure> item and doesn't implement many Podcasting 2.0 features.

I would like to automatically migrate feeds of the podcast index database to the PeerTube podcast feed and also automatically redirect the podcast index to the podcast feed when someone tries to add the "classic videos" feed. I imagine the following solutions:

• Use a tag in the feed like <itunes:new-feed-url> so the podcast index crawler automatically follows the redirection
• Automatically redirect the podcast index crawler using HTTP header if the PeerTube instance detects it (using the user agent?)
• Another solution?

Thank you very much!

We might want to use a <podcast:txt> tag for this. Something like:

<podcast:txt purpose="p20url">https://peertube2.cpy.re/feeds/podcast/videos.xml?videoChannelId=31158</podcast:txt>

The <itunes:new-feed-url> tag is used in situations where the old feed url is going to go away. If that isn't the case here, then it would make sense to use a tag that would just direct 2.0 apps and directories to a better version of the feed.

Thoughts?

When those were indexed the first time, discovery, they were in the gap between the old RSS format and the new, as I did Server Version sniffing to weed out the ones that supported the new format and "upgraded" all feeds that were found.

I don't have that code any more, it is stuck in a dead server, but I can rewrite it in a jiffy, if needed, but would require privs in the API to rewrite/update the URLs.

Using <itunes:new-feed-url> would actually be the easiest variant, as one would compare fetched URL with URL inside the new-feed-url and if they don't match, fetch the new-feed-url.

I like this idea! I can support this in next PeerTube version

I added the tag on latest peertube dev branch.

You can see it in action on https://peertube2.cpy.re/feeds/podcast/videos.xml?videoChannelId=31158 or https://peertube2.cpy.re/feeds/videos.xml?videoChannelId=31158

I see this is now in production [1][2]

<podcast:txt purpose="p20url">
https://tube.kockatoo.org/feeds/podcast/videos.xml?videoChannelId=1032
</podcast:txt>

And a podcast with different matching [3][4]
