Sorry, I should have looked closer at this earlier in the process.

Honestly, this is way too complicated. Also many of these things will change with the new frontend.

Sorry this is best to but on hold for now. For the sake of reference, things I'd do differently:

• Auth like that in the url is very insecure, as that token, possibly with read/write access will be in plain text in the podcast app, in the logs, probably more places. We'd be better off to remove auth read only on the media files and the XML file, similar as with the cast integration. Or look into other ways how to lock down access...
• The caching approach and transcoding the media files on request will likely not be feasible on lower end hardware, as you'll reach timeouts. So mp3 files should just go next to the mp4 files. Then you also don't need a separate mp3 route for that, as it's just part of media.

Ultimately, I appreciate the attempt, but we'll have to revisit that at a later point in time and look into implementing that in a way that is better integrated and more a audio mode that can also be used as podcast.
