@dirkf commented on GitHub (Apr 19, 2022):

The error message is quite correct because when Invoking downloader on 'https://.mp4', the string between / and . is empty. Obviously that's not a valid download link.

The reason is that the file member of the video object in the JSON data is empty:

  'video': {
    'id': '391634853',
    'file': '',
    'file_cast': '',
    'cast_available': true,

hmm, that's interessting, like I've noticed some time ago (when I had problemms with using ytdl with cda.pl) cda provides 2 types of videos (URLs)

for series (like that this issue is about)
for single films (e.g. https://www.cda.pl/video/218720891)
the interessting thing is, that for that second type, everything works fine

@dirkf commented on GitHub (Apr 20, 2022):

If the site doesn't offer a version of the content that you can play in your browser with EME disabled (or not implemented), yt-dl can't fetch it.

Broadcasters that use DRM implement it in different ways. Some apply it universally, some sporadically, some depending on the demand of the content originator.

Unless you can demonstrate that the show is playable as above, all we can do with yt-dl is change the extractor to report a DRM error. In https://github.com/yt-dlp/yt-dlp, the extractor could be made to understand --allow-unplayable-formats so as to allow you to fill your disk with apparently pseudo-random large files.
