ERROR: Unsupported URL: https://www3.nhk.or.jp:443/nhkworld/en/ondemand/video/<some_video_id_goes_here>

Videos on the site expire, some only last a week or so and some for 30 or more days.

The call to the http://api.nhk.or.jp/nhkworld/vodesdlist/v1/all/all/all.json looks like it returns the correct data.

I cloned youtube-dl and created a branch to work on but I did not get far. Someone familiar with the code can probably fix it faster than I can. But I will keep looking at it and try things anyway. Since I'm over my head I am filing this issue.
