Provide a description that is worded well enough to be understood

npo.py line 240 has a json request that needs to be done with a POST method, where it previously was a GET.

Provide verbose output that clearly demonstrates the problem

• 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
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

the video is DRM protected.

[VDK]

no the way how the API works has changed since monday. This Kodi video add-on was updated yeseterday

[bashonly]

OP's example URL is DRM-protected, but @VDK is correct that the API is requiring POST requests even for non-DRM content, e.g. https://www.npo3.nl/the-genius/21-11-2022/VPWON_1341105

this is likely not a complete fix though, as some of the other tests in the extractor still fail

[ttencate]

I can confirm that the patch works.

[dirkf]

Seems like the playlist IEs inherit from NPOIE for no reason?

[dirkf]

Also:

• the live radio page has changed URL and structure
• do radio fragments still exist?
• when handling npo:NPO_ID either from command-line or from redirection by a subsidiary extractor, the npo:... URL can't be passed in the API requests (HTTP 500).
