### Region

worldwide

### Example URLs

https://www3.nhk.or.jp/nhkworld/en/tv/72hours/20221129/4026171

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

Some NHK video webpages like this
https://www3.nhk.or.jp/nhkworld/en/tv/72hours/20221129/4026171
include a (seemingly) embedded video with a pulsating play button.
I don't know if this video is thought to be played embedded(ly) or trigger a redirection.
When clicking on the play button, my Firefox instance does the latter and redirects here:
https://www3.nhk.or.jp/nhkworld/en/ondemand/video/4026171
On this landing page, there finally is the playable video.

When running yt-dlp with those URLs,
the 1st URL fails (with the error log provided below)
the 2nd URL is downloaded correctly.

Maybe the NHK extractor can be enhanced to use the 2nd URL when the 1st URL is provided ?

The video in the 1st URL links to the 2nd URL:

Extract from the source code:
`<a href="/nhkworld/en/ondemand/video/4026171/" class="c-tv-episode-info-video-navigate"><div class="c-tv-episode-info-video-navigate-icon"><!----> <img src="/nhkworld/common/assets/live/images/c-tv-episode-info-video-navigate/icon-nav-on-demand.svg" alt=""></div></a>`
