Hello,

I do not konw if this is the correct place to ask this question. But as I saw that there a Question purpose in the questionary I am posting it.

The question is: is YouTube using MPEG-DASH for delivering its videos?

I see that if I use the -F option in youtube-dl for some videos there is no "DASH video", e.g., https://www.youtube.com/watch?v=Us-TVg40ExM. So is YouTube maintainig a connection to the server and requesting the "piece" of video by the "range" field of the HTTP request? Or is it downloading fixed-time segments like stadarized by DASH?

Thank you!
