### Region

Germany

### Example URLs

- Single episode: https://www.ndr.de/kultur/Barbara-Nuesse-liest-Der-Akkordeonspieler-Folge-1,audio1468520.html
- Playlist: https://www.ndr.de/kultur/buch/Barbara-Nuesse-liest-Der-Akkordeonspieler-von-Marie-Luise-Scherer,akkordeonspieler104.html
- Overview of audiobooks: https://www.ndr.de/kultur/sendungen/am_morgen_vorgelesen/index.html

### Provide a description that is worded well enough to be understood

These are publicly available audiobooks that are usually playable for a week after release of an episode.

 The generic downloader worked fine until very recently if you supplied the direct link for the episode. The whole playlist was never recognized. 

I think they might have switched to [podloveplayer](https://podlove.org/podlove-web-player/) recently and yt-dlp doesn't know what to do with that. I'm not sure how popular that player is, but yt-dlp support might help with other sites as well as long as they use that. 

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
