[Bug]: Podcasts downloading multiple files

[marsbars-marsbars]

What happened?

When manually getting new episodes to download, its almost as audio bookshelf does not recognize there already is a file / episode and it downloads again with a rather long random string to the filename, in some cases.

What did you expect to happen?

To recognize existing episodes and now re-download. (image shows another instance of multiple files )

Steps to reproduce the issue

2. Go to Episodes.
3. Change date back to ~ couple years to decades.
4. Set limit to anything from 3 - 3,000
5. Click the check new downloads

To clarify, is the auto download schedule triggering again before finishing downloading episodes? That could happen depending on how often you are checking for downloads, how many are downloaded per check, and your download speed.

No. I dont have auto download enabled, I just go and request past episodes and this is the result.

I've selected various ranges, from 3 to 3000; same results.

I'm not able to reproduce this. The way that the check for episodes works is it runs a function that filters out any episodes that you already have.

It primarily uses the guid which is set in the RSS feed for every episode. It falls back on using the enclosure url which is the url to the audio file in the RSS feed.

Those values are only set if the episode is downloaded using Abs. They are not set if the episodes are scanned in from your file system. I suspect something is going on with your setup where the episodes are being scanned in from the file system.

audiobookshelf/server/objects/mediaTypes/Podcast.js

Lines 213 to 217 in c4610e6

	checkHasEpisodeByFeedEpisode(feedEpisode) {
	const guid = feedEpisode.guid
	const url = feedEpisode.enclosure.url
	return this.episodes.some((ep) => (ep.guid && ep.guid === guid) || ep.checkEqualsEnclosureUrl(url))
	}

The easiest way to check if Abs has linked the podcast episode with an episode in the RSS feed is to use the search button on the podcast page.

When the episode is linked to the RSS feed you will see a green checkmark. If it is not linked (or just not downloaded) it will be a checkbox.

There is functionality built into Abs to match episodes with an episode in the RSS feed. To match them one-by-one you can press the edit button on any episode and use the "Match" tab.
To match all of the episodes in bulk you can use the quick match all episodes.

Interesting, some of those files/series might have come from a copy of other downloads because I frequently received socket errors. I'll re-test with deleting a few series and then downloading only ABS and seeing how it behaves. Thank you !
