Description

In this example it is 1 single mp4 file if I inspect in my browser. In other cases it the file loads in chunked .ts and if I inspect browser I see a network request for something like https://gumroad.com/r/59bd0a45c6b12585318c698c03e4752d/kSlnXCva3zW8Ryu-u5hT4g==/index.m3u8 (FYI this will 404 on this specific video but other real videos work this way).

If i pass the m3u8 URL to youtube-dl it downloads the video fine, but I'd like to avoid having to inspect element and pass the URL like above.
