### Provide a description that is worded well enough to be understood

Tried to download video/audio with newest nightly build 2024.08.26.232811.
It says the site is unsupported. It think it triggers the wrong thing on the Twitter Card. It should follow the video tag with the mp4 Url.

### Provide verbose output that clearly demonstrates the problem

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