Provide a description that is worded well enough to be understood

Cannot download this video or any other video on this site. When pressing F12 in web browser in Network tab there is no mpd or m3u8. Segment numbering are two part and not in order. Also The Stream Detector cannot detect anything.

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 site GETs https://dev.epicgames.com/community/api/learning/post.json?hash_id=4ORW (4ORW being the ID in the page URL), which returns JSON including this at .blocks[0]:

    {
      'type': 'video',
      'video_id': 'V_0hmdLF',
      'provider': 'kaltura',
      'caption': '',
      'autoplay': false,
      'video_url': 'qsep://cdn.qstv.on.epicgames.com/2aef4ec0-31df-4855-9eec-3cc75804689c?s=eyJraWQiOiJMRW13ZEZzVmMiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJPSndjYkhqSWJsejVEaEFocTh6ai9lWjB4WHpsSUtzemk0cFN2UmFnU2xRPSIsImV4cCI6MTcxNDA0MTM0MH0.T4hwrmVm2LHpWhFu3pF3zqbhmfWftJ9xgQx9krnr2eggeU4kBsROmoKT-aS2pKOpOIbA_Ktwv1QT09pZt4vtzw',
      ...,
    },

Kaltura is a video hoster that has an extractor; probably the qsep: scheme is an internal reference like blob:.

In the JS loaded from https://dev.epicgames.com/community/assets/main.2c420dfc13ced555.js, there is:

          kaltura: {
            partner_id: 2501632,
            uiconf_id: 50465532
          },

Someone skilled in the Kaltura arts might be able to conjure a video from partner_id=2501632, uiconf_id=50465532, video_id=V_0hmdLF but the best I got was Kaltura said: The access to this service is forbidden since the specified partner is blocked (1).
