Description of your issue, suggested solution and other information

NHL extractor fails.

Thanks
Ringo

I'm not sure if that's an extractor fail, as the m3u8 files have info about 5000k files, while the HTML source only refers to 1800k files (the mp4 5000k files don't exist as shown in the 404 error above).

Currently I check all formats one by one. If there's a better approach, please leave a comment here or open a new issue.
