Self-hosted podcast aggregator/streamer, NOT downloader - Lemmy.world

So I’m looking for a solution that is a self-hosted (docker preferably) podcast streamer/aggregator. I DO NOT NEED A DOWNLOADER. Ideally, I’d be able to add RSS feeds and stream them through a web interface that will keep track of progress, etc. I’m not talking about something that serves up downloaded podcasts either, I can do that in Plex/Jellyfin.
