Example URLs

Single Audio: https://www.deutschlandfunk.de/tanz-der-saiteninstrumente-das-wild-strings-trio-aus-slowenien-dlf-03a3eb19-100.html

Provide a description that is worded well enough to be understood

When visiting the mentioned example url with browser, there is a play button ("Hören"). On clicking it, my browser loads (among others) https://dradiohls.akamaized.net/hls/2023/03/03/tanz_der_saiteninstrumente_das_wild_strings_trio_aus_dlf_20230303_2105_03a3eb19/master.m3u8

Feeding this url as parameter to yt-dlp yields yt-dlp to succesfully download the wanted audio file. But it seems a little bit uncomfortable to harvest the url by using browser's developer tools.

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

A good target is <button alt="Anhören" ...>.

Then extract_attributes() and find these data items:

• url <- data-audioreference or data-audio or data-audio-src or data-audio-download-tracking-path
• id <- data-audio-diraid
• duration <- data-audioduration or data-audio-duration
• title <- data-audiotitle or data-audio-title or data-audio-download-tracking-title
• thumbnail <- data-audioimage
• uploader <- data-audio-producer, perhaps
• series <- data-audio-series
• channel <- data-audio-origin-site-name, perhaps.

Apparently not a very disciplined data dictionary at DLF.
