Short answer: You can't; It's impossible
Long answer: Those are HLS files, which is a media format akin to a playlist. You might have luck changing the file extension to .m3u8 and playing it in mpv/vlc, but it will likely fail as Patreon puts expiring signatures in the URLs.There is no full mp4 in HLS. HLS is a m3u8 playlist with a million small mp4 files in it. You should get that playlist, download all the files and stitch them together. Youtube-dl does that.
