Can not extract 1080p format

[yemingfeng]

Hello,
First of all, thank you very much for providing this framework, which allows me to download various contents anytime.
I am currently using the latest version: 4.11.5.
But I found that I cannot obtain the 1080p format, only 360p and 720p.
For example, URL: https://www.youtube.com/watch?v=8xg3vE8Ie_E
How can I obtain 1080pHD?
Thank you again for your help.
