When using a browser (or any HTTP) download or watching a video on youtube, I notice the download is very consistent... mostly peaking at the bandwidth. However, when I use youtube-dl to grab a video, it shows a very clear roof-tiling pattern; it goes up and when it reaches peak there is a sheer drop to almost zero... after which the speed starts to raise again and repeating this process.

Not seeing this using using Aria2 (on Windows) as an external downloader:

PS> choco install aria2
PS> youtube-dl --external-downloader aria2c --external-downloader-args "-j 12 -s 12 -x 12 -k 5M" https://www.youtube.com/watch?v=7IvmzEuVkSY
