The url variable is never defined

Yes it is, just before the pasted section.

oh you are right, nevermind then

Something like Sponsorblock for non youtube videos would be great. Another killer feature for me are automatic chapters if the podcast doesn't provide any

Hi, as a Antennapod user this sounds great. Can I sync my current playback position? Last time I tried Gpodder sync it felt very buggy

Yes, it works pushing the button on titlebar's left corner. Playback position is saved after pause, podcast swith or close the app. There is a setting to sync automatically after closing the app. It works well for me at least.
