While the download was in progress, I ran the exact same command in another terminal, another folder, and the download was completed in a few seconds:

Description
Hello,
Important: The problem is random, maybe 1 chance on 8 to produce it. You have to download several videos in a row (about 10) to notice it.
Since a few weeks, randomly a youtube video can be slowed down to 48 Kio/s, so it takes 5-10 minutes to download a short video of 5 minutes instead of 4, 5 seconds, often the download does not succeed and stops after a few minutes.
This happens on several servers, several internet providers as well as with my private connection.
I even managed to launch a second download in parallel when the first one was taking time, the second one finished in 1 seconds, the first one in 5 minutes and was interrupted before the end. Same video, same connection, same command. (tested only with ipv4 because I don't have ipv6 on my servers or with my internet connection).
Attached is an extraction of the results with --dump-pages.
