There's often a lot of magic involved in extracting the video URLs from
re-using cookies and referrers, and so on. Please do use the tool
youtube-dl, or the maintained fork yt-dlp, to extract these URL or even
to download the actual videos. The tool figures out the formats, the
URLs, and often even the de-encryption (not DRM though) of many many
web pages. (It can even call ffmpeg to download, and will do so by
default in many cases.)
To get the (or a) URL:
$ youtube-dl -g http://website-of-choice/page
If youtube-dl doesn't support a certain page, I load the page in Chrome
and look for the original file or m3u8 on the Network tab of the
developer console (Ctrl+Shift+C), and then pass that to ffmpeg.
