### Region

Czechia

### Example URLs

- Single video: https://esc365.escardio.org/event/1096

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

esc365.escardio.org uses Brightcove player but the page is unknown and falling back to generic extractor. When forcing brightcove:new, it fails to extract information.

Video itself can be downloaded from https://players.brightcove.net/6169276219001/VkDcrLTAv_default/index.html?videoId=ref:EVT1096 (brightcove player with parameters found in https://esc365.escardio.org/event/1096 page source), but it would be great to add direct support for esc365.escardio.org.

### 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
