I see the obvious differences of the various resolutions, but there are files that appeaer to be identical, with the same file size and resolution, but the letters “hls” are added to the video. That said, I would like to know if there is a certain one that I should be using to script.
Honestly I don’t really know the difference there and was asking myself the same question. It shouldn’t matter what file you download though.
Found this for “what is hls?” Maybe it could answer something.
When Realcumber says to avoid, I avoid whenever possible.
